RFL NCM

Network Communications Module

DESCRIPTION

The Network Communications Module (NCM) is an Asynchronous Data Module designed for use in

RFL IMUX 2000 T1 and E1 multiplexers. It provides one DCE Half/Full-Duplex channel between an

unlimited number of locations using a single 64 kbps DS0 time slot. The NCM provides a fast and

reliable NMS communication path between nodes of a T1 or E1 network, and can also be used for

party-line applications such as DNP and Modbus networking.

The NCM is remote-controllable when installed in an RFL remote controllable shelf. The following

module parameters can be configured remotely via NMS or locally via DIP switches. A DIP switch

setting selects whether the card is in remote or local mode.

INSTALLATION

Before the RFL NCM module can be placed in service, it must be installed in a multiplexer shelf.

Installation involves determining the module slot in the Main Shelf or Expansion Shelf where the

module will be installed, inserting a Module Adapter into the rear of the shelf behind the module slot,

connecting all signal and power wiring to the Module Adapter, checking the settings of all switches,

and inserting the module into the front of the shelf.

NOTES

Power supply and time slot considerations may affect the installation of this module into an

existing multiplexer shelf. Refer to the multiplexer manual for more information.

The following instructions are provided for installing an RFL NCM module into an existing system. If

the module was included as part of a system, installation was done at the factory. Otherwise, proceed

as follows:

Carefully inspect the module for any visible signs of shipping damage. If you suspect damage

to the module, immediately call RFL Customer Service at the number listed at the bottom of

this page.

Determine the module slot in the Main Shelf or Expansion Shelf where the module will be

installed.

The RFL NCM module occupies one module slot in the Main Shelf or Expansion

Shelf.

Determine which module adapter will be used to make connections to the RFL NCM module.

Each module in the IMUX 2000 multiplexer requires a Module Adapter. The

module adapter provides the appropriate connector for the desired interface.

There are three Module Adapters that are compatible with the RFL NCM:

The MA-402I module adapter is shown in Figure 1. This module is a two-port RS-

232 I/O which has two 9-pin D-subminiature (DC-9) connectors on its rear panel.

Each of these 9-pin connectors is wired in a standard RS-232 configuration as

shown in the table at the bottom of the figure. Each connector is labeled to show

the corresponding port on the NCM module.

The MA-485 module adapter shown in Figure 2 supports both 2-wire and 4-wire

RS-485 applications. The 2-wire mode supports only half-duplex, and the 4-wire

mode supports both half and full duplex. The MA-485 is typically used for party-

line applications such as DNP and Modbus networking, or simple point-to-point

applications. This module has one 6-position removable terminal block on its rear

panel, which is wired in accordance with the table in Figure 2.

The MA-490 module adapter shown in Figure 3 is an RS-232/Telnet I/O module

adapter used for systems that have an RS-232 port which needs Telnet link

capability. This module has two RS-232 ports using DB9 connectors and one

Ethernet port using an RJ-45 jack on its rear panel. One of the RS-232 ports is the

Craft port and the other is the Data port. The Craft port is used to set up TCP/IP

parameters, and the Data port is used for communications. Refer to the tables in

Figure 3 for wiring information.

Make sure the module adapter you are installing is correct for the desired

application. Make sure the programmable jumpers on these modules are set to the

desired configuration, as applicable.

Insert the Module Adapter into the rear of the shelf directly behind the module slot where the

RFL NCM module will be installed. Secure the module with the screws provided.

Connect the Module Adapter to the user equipment using the connector pin assignments

detailed in Figures 1, 2, or 3 as applicable.

Refer to Figures 4 & 5, and Table 1 for the location of DIP switches on the NCM module.

Set the module address using DIP switches SW1-1 through SW1-6 for the desired remote

address (SCB address).

For remote access, each channel module in the IMUX 2000 must have a distinct

module address. Valid addresses are the numbers “1” to “36”. In most

installations the address will be set to the number of the slot the module is

occupying. Table 3 shows the switch settings for the module address. (Consult

your multiplexer manual for details on using the remote access and configuration

features of the system.)

In E1 systems, set DIP switch SW2-8 to enable or disable CAS (channel associated signaling).

In T1 systems, this switch setting is ignored.

Place SW2-8 in the UP position to disable CAS.

Place SW2-8 in the DOWN position to enable CAS.

Select an unused time slot for the NCM using DIP switches SW2-1 through SW2-5. The NCM

uses one 64 Kbps digital time slot within the multiplexer’s aggregate rate. Set the time slot

using direct binary coding as shown in Table 4. Refer to the multiplexer manual for guidelines

on time slot selection.

Note that selecting an invalid time slot will disable the module. In T1 systems, only time slots 1

through 24 are allowed.

In E1 systems, time slots 1 through 31 are allowed, however, time slot 0 is reserved and cannot

be used. Time slot 16 is also reserved and cannot be used if CAS is enabled in E1.

10.

Select Bus direction by using DIP switches SW2-6 and SW2-7.

Place SW2-6 in the DOWN position to transmit in the A direction and receive

from the B direction. Place SW2-6 in the UP position to disable transmit in the A

direction and receive from the B direction.

Place SW2-7 in the DOWN position to transmit in the B direction and receive from

the A direction. Place SW2-7 in the UP position to disable transmit in the B

direction and receive from the A direction.

11.

Switches SW3, SW4 and SW5 are only used when the NCM module is in the NMS application

mode. In all other application modes these switch settings are ignored. Set Rotary Switches

SW3, SW4, and SW5 to the local CM address. SW3 sets the hundreds position, SW4 sets the

tens position, and SW5 sets the units position. The NCM supports CM addresses from 001 to

999. The “local CM address” must be set to the same address as the local Common Module

(CM3B, CM3C, CM3R, CM6B, or CM4).

12.

13.

Set DIP switches SW6-1, -2, and -3 to set the baud rate in accordance with Table 1. If the

system application mode is NMS, the baud rate must be set to the same baud rate as the local

common module. Otherwise, any baud rate can be used.

Set DIP switches SW6-4, -5, and -6 to set the parity in accordance with Table 1. If the system

application mode is NMS, the parity must be set to the same parity as the local common

module. Otherwise, any parity can be used.

Set DIP switches SW6-7 and SW6-8 to set the word length (number of bits per character) in

accordance with Table 1. If the system application mode is NMS, the word length must be set

to the same word length as the local common module. Otherwise, any word length can be used.

NOTE

In any Application Mode, the Baud Rate, Parity and Word Length settings of the NCM must

match at all nodes in the network. Additionally, In the NMS application mode, the Baud Rate,

Parity and Word Length settings of the NCM and CM must match at all nodes in the network.

15.

Switches SW7-1 and SW7-2 are only used when the NCM module is in the NMS application

mode. In all other application modes these switch settings are ignored. Use DIP switches SW7-

1 and SW7-2 to set the CM address Pass Setting in accordance with Table 1. Typically, if all

the nodes in a T1/E1 network have an NCM as shown in Figure 6, the address Pass Setting will

be set to only pass messages with addresses equal to the local CM address of the NCM. This

feature prevents the local node from responding to queries sent to remote nodes.

Place SW7-1 in the DOWN position

Place SW7-2 in the UP position

In this example, all inter-node communication is done via the NCM path and FDL (Facility

Data Link) is not used.

15. (continued).

If some of the nodes in a T1/E1 network have an NCM, and others do not as shown in Figure 7,

the address Pass Setting will be set differently at some of the nodes. In Figure 7, nodes 1, 2 and

3 have NCM modules, and nodes 4 and 5 do not have NCM modules. This network requires

that at nodes 1 and 2, SW7 is set as follows:

Place SW7-1 in the DOWN position

Place SW7-2 in the UP position

And at node 3, SW7 is set as follows:

Place SW7-1 in the UP position

Place SW7-2 in the DOWN position

Additionally all 5 nodes must have the CM setting UNIV = ON to enable the FDL path. This

allows a user to “transparently” communicate to all nodes regardless of which node the PC is

connected to. If the PC is connected to node 1, 2 or 3, a user can “talk to” nodes 1, 2 or 3 via

the NCM path, and “talk to” nodes 4 and 5 over the FDL path. If the PC is connected to nodes

4 or 5, communication to all nodes is over FDL.

SYSTEM OVERVIEW

The Network Communications Module (NCM) is an Asynchronous Data Module designed for RFL

IMUX 2000 T1 and E1 Multiplexers. The NCM provides one DCE Half/Full-Duplex channel between

an unlimited number of locations using a single 64 kbps DS0 time slot. The NCM provides an NMS

communication path between nodes of a T1 or E1 network, and can also be used for party-line

applications such as DNP and Modbus networking. The NCM automatically detects if the system is T1

or E1 and configures itself appropriately.

The NCM in NMS application mode is not required for T1, but could be utilized to speed up network

communications, or provide a communication path to remote locations. The NCM is required for E1

systems, because an out of network communication path does not exist.

The NCM supports RS-232, RS-485 (2W and 4W), and Telnet interfaces with the MA-402I, MA-485

and MA-490 Telnet I/O respectively, and supports Equipment and Payload Loop-backs. The NCM

does not support handshaking of any kind, and does not respond to RTS. The NCM uses Stop-bit

reduction during transmission of asynchronous data as a means to compensate for received baud

slightly greater than normal. For RS-232 applications, the NCM does keep CTS, RLSD and DSR

active at all times for external equipment requiring these to be active.

The NCM supports either one or two ports depending on the interface installed. Each port includes a

UART, and can transmit to and receive from the T1/E1 bus, and transmit to and receive from one

another, depending on the configuration and application. The ports support 38.4k, 19.2k, 9600, 4800

and 2400 baud, support 7 or 8 data bits, and support Even, Odd, Mark Space and No Parity.

The NCM utilizes a proprietary communication protocol over T1/E1 consisting of two data and two

idle/address frames. The two data frames make up the entire data package, and are transmitted and

received in consecutive frames. The idle/address frames occur only during idle-time between data

packages, and are also transmitted and received in consecutive frames. Only the NMS Mode currently

supports addressing.

The NCM does not support signaling bits within the T1/E1 data stream, however, the CAS setting on

the NCM module will “block” the selection of timeslot 16 for an E1 multiplexer using CAS,

preventing the NCM from potentially disrupting other modules in the network.

The NCM supports “Address Passing” and “Character Pacing” in the NMS Mode of operation.

“Address Passing” qualifies messages prior to sending them out of port (#2) to the CM-X module.

“Character Pacing” emulation is done as a result of the “Address Passing” requirement.

A Rogue Control feature is available which prevents a rogue PC program or another module from

“stepping” on the NCM time slot, and bringing down the entire NCM Path.

NCM BACKPLANE AND POWER CONNECTIONS

The NCM occupies a single slot in the multiplexer chassis and conforms to the RFL IMUX 2000 back

plane signal format. All T1 and E1 signals, and control signals passing through the back plane,

interface with the cross point Lattice device (U6). All inputs and outputs of the Lattice Device are

pulled up to 3.3V through approximately 50K Ohms.

The NCM requires digital +5Vdc and digital ground connections to the back plane. TP2 and TP12 are

the ground test points. The digital +5V from the back plane is routed to the Hot Swap Controller (U1,

which controls the ramp of the power to all of the ICs. The ramped digital +5V supply is only directly

used to provide power to the LEDs, DS1 through DS13, and can be monitored at TP1.

Linear voltage regulators U3 and U4 step-down the +5V digital supply to produce +2.5V and +3.3V

supplies respectively. The +2.5V is used exclusively to power the Actel FPGA (U2). The 3.3V is used

to power the Lattice device (U6), the I/O of the Actel (U2), the 49.152mHz oscillator (U11), and the

pull-up resistors on the module. The +2.5V and 3.3V supplies can be monitored at TP3 and TP4

respectively. All pins which connect to the back plane, except for voltages and grounds, are cut back to

prevent components from being driven before the module is fully powered.

TX INPUT PORTS

The NCM module supports one or two TX input ports depending on the interface adapter installed (i.e.

MA-402I, MA-485, or MA-490). An asynchronous data signal is applied to a TX input of the

appropriate interface adapter. The data signal is converted from RS-232, MA-485, or Ethernet to a

logic signal on the interface adapter before being fed through the back plane to the NCM module.

These logic signals pass through the Lattice device (U6), and are applied to the Actel’s (U2) UART

receive section. Indication of TX input activity can be observed at the IN1 and IN2 LEDs, and via the

NMS software.

RX OUTPUT PORTS

The asynchronous logic data signal is transmitted by the UART Transmit section of the Actel (U2),

and passes through the Lattice device and back plane to the interface adapter. The interface adapter

converts the logic signal to the appropriate interface format (i.e. RS-232, RS-485, or Ethernet),

depending on the interface adapter installed. The CTS and RLSD are always active for RS-232

applications (MA-402I) that require these to be active. Indication of RX output activity can be

observed at OUT1 and OUT2, and via the NMS software.

LOGIC ARRAY (ACTEL DESIGN)

The Actel FPGA controls, processes, and coordinates all functions of the NCM. It interfaces switches,

LEDs, SCB bus signals, T1/E1 bus signals, and I/O control lines. The Actel design can be broken

down into the following nine functions: SCB, Application Modes and Interfaces, UART Receive,

UART Transmit, T1 Transmit, T1 Receive, Rogue Control, Loop-backs, and Baud and Clock

Generator.

1. SCB MODULE

The SCB circuit is used to generate the read, write, and address data necessary to transfer control and

status data to and from the SCB bus. The SCB address is configured externally via SW1 and is

selectable between 1 and 36. The SCB circuit also communicates to the Common Module the

following information: Card Type (117), number of configuration bytes, and number of status bytes.

In LOCAL mode the position of configuration switches (SW1 through SW9) are “read” by the

Common Module, and then converted into standard P code and S code format.

In REMOTE mode, the NCM module does not rely on the position of configuration switches (SW2

through SW9). Instead, the Common Module “writes” the configuration to the NCM. The NCM

requires that it receives exactly the same information three consecutive times before it accepts the

updated configuration information as correct.

NCM “Service” is qualified in order to minimize user setup error, and prevents operation if the quality

of the bus signal prevents the logic from determining whether the multiplexer is T1 or E1. In general,

E1 does not allow the use of TS0 and TS16 if CAS is enabled, and T1 does not allow the setting of

TS0 or any setting greater than TS24. It is the users responsibility to be aware of the network setup

before selecting a channel to use. This qualification does not detect or prevent “stepping” on a time

slot previously in use, including those that may be used for Fast Reframing, or network

communications (NMX in E1). NCM “Service” is also qualified for non-existent and invalid modes of

operation.

2. APPLICATION MODES AND INTERFACES

NCM operation depends on the selected Application Mode, and the type of I/O interface installed. The

NCM uses an I/O type ID to determine which I/O is installed. If the installed I/O is the MA-485, an

additional bit is used to indicate whether it includes one or two ports. The two port version does not

currently exist.

The NMS includes the following Application Mode settings, and I/O types

Application Mode settings

NMS Mode

Broadcast Mode

Master Mode

D&I Slave Mode

End Slave Mode

The purpose of the NMS Mode is to provide a high-speed communication path between nodes for

NMS. The other application modes provide a communication path between an MTU and several

RTUs. The NMS Mode of operation requires the use of the MA-402I with two RS-232 ports, or the

MA-490 with two RS-232 ports and an Ethernet port. In respect to the NCM, Port 1 is the “Local” port

and Port 2 is the “CM” port. The additional RS-232 port on the MA-490 is used to configure the local

Ethernet Port. The NMS mode is a Broadcast-type application but includes “Address Passing” and

“Character Pacing” circuits for the “CM” port.

In the Broadcast Mode of operation, all nodes receive the same data regardless of who is transmitting.

The broadcasting applies to both ports of a two-port I/O.

The Master Mode of operation designates a particular NCM at a node, as the master. If the NCM is set

up for TERM/DI-A or DI-B operation, and the I/O has only one port, the actual functionality is the

same as the broadcast mode. If the NCM is set up for both DI-A and DI-B operation, the data received

from either bus is terminated and is not passed back onto the bus. If the I/O has two ports, Port 2 is

always the slave to the Port 1 master, and cannot transmit onto or receive from the T1 bus. Typically,

the master transmits to and receives from all of the slave locations. Only one slave can transmit onto

the T1 bus any time, otherwise the data received by the master will be corrupted.

The D&I Slave Mode of operation designates an NCM at a D&I node as slave that must pass data thru

but only transmits to and receives from the master. Set for TERM/DI-A or DI-B operation towards the

master location. Only one slave can transmit onto the T1 bus any time, otherwise the data received will

be corrupted.

The End Slave Mode of operation designates the particular NCM at a node as the terminating point of

a network that is not the master. The NCM is setup for TERM/DI-A or DI-B operation depending on

the direction to be terminated. If the I/O has only one port, the actual functionality is the same as the

broadcast mode. If the I/O has two ports, both ports are slaves that transmit to and receive from the

master, but not with one another.

The NMS uses the following I/O Interface types:

I/O Types/Module Adapter

RS-232 (or none)/ MA-402I

Ethernet/ MA-490

RS-485 4W/ MA-485

RS-485 2W/ MA-485

The MA-485 I/O is used for both 2W and 4W RS-485 applications, and will support all of the NCM

Application Modes except NMS mode. The jumper position on the I/O is set to either “2W” or “4W”,

and sets the Type ID accordingly. The input and output serial data is routed as required for the selected

RS-485 type. In “4W” mode, a jumper on the I/O will force the driver to always be enabled so that an

idle condition produces a MARK output. The “2W” mode only supports half-duplex operation, while

the “4W” mode supports both half and full duplex operation.

3. UART RECEIVE SECTION

The UART receivers are programmed for the appropriate baud, number of data bits, and parity for the

input data expected to be received. The input data, including start, stop, and parity, is sampled by a

64X nominal baud internal clock. The received parity bit is compared to the parity calculated by the

UART> Once the data is recognized as valid, the data is latched and is ready for transmission. The

UART receiver is reset if a framing error, parity error, or break indication is detected.

UART TRANSMIT SECTION

The UART transmitters are programmed for the appropriate baud, number of data bits, and whether or

not parity is to be enabled for the output data to be transmitted. This circuit reacts to a “Data Ready”

flag, and latches the data into its 16-byte FIFO. The data is then loaded into the transmitter shift

checked or regenerated. The end equipment is responsible for parity checking.

The NCM module utilizes two additional transmitter circuits that interface with the Common Module

exclusively in NMS mode of operation. These circuits include “Address Passing” and “Character

Pacing”. Typically, the NCM will allow messages meant for the particular node in which it is

physically installed, to pass, and block all others. However, the NCM can be configured to pass “any

address”, or a wide-range of addresses greater than or less than a specified address.

The Common Module is also given permission to talk to the bus in response to a message qualified as

an address match. All other Common Modules in the network will be forced off the bus as a result of

any valid address header but no address match. The most recent addressed Common Module will have

control of the bus until any other Common Module is addressed.

“Character Pacing” is required so that the NCM does not saturate the Common Module port with a

continuous data stream of characters following an address match. This prevents the Common Module

processor from “missing” characters if they are received without idle time between consecutive

characters.

5. T1 TRANSMIT MODULE

The T1 transmit module acknowledges the “Data Ready” flag set by either local UART receivers, and

latches the (character) data. The data is then transmitted in consecutive T1 frames at the proper time

slot on the positive edge of the T1 clock. Indication of T1 transmit can be observed at the TXA and/or

TXB LEDs, and via the NMS software.

If the NCM has both busses enabled, the data received from a T1 bus is re-transmitted back onto the

same bus on the next frame. This pass-thru data has higher priority over the data from the local UART

receivers.

The NCM, for all modes except NMS mode, transmits an idle pattern when data is not active at either

UART receiver, or the T1 bus (if applicable). The idle pattern may be interrupted at any time when

data is ready to be transmitted.

In NMS mode only, the NCM transmits an address pattern when data is not active at either UART

receiver, or the T1 bus (if applicable). The address pattern may be interrupted at any time when data is

ready to be transmitted. The address frames are received and terminated at the adjacent NCM in the

network.

6. T1 RECEIVE MODULE

The T1 receive module clocks in the receive data at the proper time slot on the negative edge of the T1

clock, and latches it one clock following the time slot. The data is decoded as being either data or

idle/address frame, and as being low or high frame.

In NMS mode, the NCM will block all data until low and high address frames are received in

consecutive T1 frames, decoded, and then determined to be a valid BCD address. Once low and high

address frames are latched, the “Address Valid” signal is activated. Indication of “Address Valid” can

be observed at the ADRA and/or ADRB LEDs, and via the NMS software. Indication of T1 receive

can be observed at the RXA and/or RXB LEDs, and via the NMS software

7. ROGUE CONTROL

The Rogue Control feature is used to prevent a rogue PC program or another module from “stepping”

on the NCM time slot and bringing down the entire NCM path. If enabled, both the local input(s) and

T1 receive inputs will monitor for rogue activity. The local port is squelched for at least two minutes

once a continuous data stream lasting for greater than 60 seconds is detected. The T1 receive data is

squelched for at least two minutes once a continuous data stream lasting for greater than 64 seconds is

detected on the bus. The T1 rogue threshold is set intentionally higher than the local port to prevent all

the nodes from reacting to a rogue at any of the local ports. However, a rogue occurring on the T1 can

(initially) trip several of the rogue detectors because all of the nodes downstream “see” the same data

pattern. (Note that the T1 received data is also squelched on a frame-by-frame basis if the T1

data/addressing protocol is not maintained. In the NMS mode, the data would remain squelched until

valid a address is once again detected.) The 0.5 seconds RED/0.5 seconds OFF cadence indicates an

active rogue at RXA, RXB, IN1 or IN2 LEDs. An active rogue status is also indicated for each input

via the NMS software.

8. LOOP-BACKS

When the NCM is enabled for Equipment loop-back, the serial data received at IN1 and/or IN2 is re-

clocked by the UART receiver(s) and then re-transmitted out of OUT1 and/or OUT2 by the UART

transmitter(s) respectively. The error status conditions are inactive, parity is not checked or re-

generated, data is not transmitted onto the T1 bus, and the EQLB LED will be illuminated orange.

When the NCM is enabled for Payload loop-back, the UART transmitter is internally connected to the

UART receiver input. The IN1 or IN2 local inputs are ignored. The OUT1 or OUT2 is held high. The

error status conditions are active, parity is checked, and the data is re-transmitted back onto the T1 bus.

The PALB LED will be illuminated orange. Only one port is activated for Payload Loop-back at a

time. Note: In broadcast or NCM mode, all ports not in the test loop may receive corrupted data

because data is received simultaneously from two sources.

9. BAUD AND CLOCK GENERATOR

The Baud and Clock Generator module divides down the 49.152mHz frequency provided by the

external board oscillator (U11). It generates the 64X Baud required for the UARTS, and clock

frequencies used for synchronous timers by other modules in the Logic Array.

LOOP TEST PROCEDURE FOR RFL NCM MODULES IN NMS MODE

INSTALLED IN DI-B CONFIGURED MULTIPLEXERS

The following procedure is used to test RFL NCM modules installed in IMUX 2000, DI-B configured

multiplexers. To test NCM modules installed in IMUX 2000 terminal multiplexers, use the procedure

on page 27 of this instruction data sheet. Before performing this procedure, make sure the system is

on-line and out-of-service.

Connect the male to female null modem RS-232 cable from CH2 of the MA-401I to the DB9

male connector on the CM I/O.

Open the door on the front of the IMUX 2000 multiplexer.

Connect a patch cord between the DS1-B EQUIP OUT and DS1-B EQUIP IN jacks on the

front of the IMUX 2000 chassis. The jacks are located on the Common Module.

With power applied to the IMUX 2000, check the indicators on the front of the power supply

module.

The POWER indicator should be lit.

Check the Service LED (DS13) on the front panel of the NCM. See Figure 4 and Table 1 for

location.

The Service LED should be illuminated green.

Check the ADRA LED (DS11) on the front panel of the NCM. See Figure 4 and Table 1 for

location.

The ADRA LED should be illuminated solid orange. (should not be red or green)

Orange indicates the NCM is receiving its own address.

Check the RXA LED (DS7) on the front panel of the NCM. See Figure 4 and Table 1 for

location.

The RXA LED should be illuminated red.

Connect the PC to the CH1 RS-232 connector using the male to female RS-232 connector. At

this point, the equipment should be connected as shown in Figure 11. Run the RFL NMS

communications software and set the parameters exactly the same as the CM and the NCM.

REMOTE CONTROL USING NMS

There are two ways to program the NCM module, locally using DIP switches, or Remotely using NMS

(Network Management Software). If your NCM module is to be used in NMS application mode, it is

highly recommended to set-up the NCM module using the DIP switches only, since the NCM card in

the NMS application mode is the vehicle for NMS communication.

Refer to the IMUX 2000 or IMUX 2000E Instruction Manuals for information on using NMS. Go to

the NCM module using NMS. Go to the NCM General Configurations and Status window for node 1.

The NCM General Configurations and Status window for node 1 of a T1 system is shown in Figure 12.

The General Configurations window is on the left and the Status window is on the right. The General

Configurations window, on the left, is where the user can change the NCM configuration parameters.

This window has three top-level pages selectable by the tabs at the top of the window as follows:

General, Address and Serial Port. The following discussion covers the settings on the “General” page.

Note that there is one check box and six parameters that must be set. The box can be checked or

unchecked and each of the six parameters must be set. The selections for each parameter can be

viewed by using the up and down arrows. Then click on the desired parameter to make your selection.

1. Module Enable

The Module Enable box can be checked or unchecked.

For the NCM module to be In Service, check the Module Enable box.

For the NCM module to be Out Of Service, uncheck the Module Enable box.

2. Time Slot

The Time Slot can be set from 1-24 for T1 networks and from 1-31 for E1 networks. Click on the up or

down arrows to make the selection.

3. Mode

There are three basic types of network modes:

Broadcast mode

NMS mode

A combination of Master, D&I Slave and End Slave modes.

Each of these modes is described in the table below.

Mode

Description

Broadcast

In Broadcast mode each node transmits to and receives from all other nodes in the

network. Typically when Broadcast mode is used, all nodes in the network are set to

Broadcast mode. Refer to Figure 13a for more information.

NMS

Typically when NMS mode is used, all nodes in the network are set to NMS mode. In

NMS mode each node transmits to all other nodes and each node selectively receives

messages from all other nodes in the network based upon addressing. In addition to

this, each node transmits its address to adjacent nodes during idle network time. Refer

to Figure 13b for more information.

Master

Typically, when one of the nodes in a network is a master, the other nodes are slave

nodes. There are two types of slave nodes: D&I slave nodes and End slave nodes.

Refer to Figure 13c for a typical network using Master and Slave nodes. The Master

node transmits to all other nodes in the network.

D&I Slave

End Slave

The D&I slave node only receives from and transmits to the master node, and it also

allows messages from the master to pass through to all other slaves. It also allows

messages from other slaves to pass through to the master.

The End slave node only receives messages from and transmits messages to the

master node

4. E1 Signaling

E1 Signaling can be set to CCS or CAS. If this is a T1 network, the E1 Signaling setting is ignored. If

this is an E1 network, set the E1 Signaling to match the local E1 multiplexer setting. For example, if

the local E1 multiplexer is set to CCS, set the E1 Signaling to CCS. If the local E1 multiplexer is set to

CAS, set the E1 Signaling to CAS. This locks out the use of time slot 16 for CAS (channel associated

signaling).

5. Rogue Detection

Rogue Detection can be enabled or disabled, and can be used in any mode but is typically used in

NMS mode. When enabled it monitors the local ports and the receive T1 messages. Rogue Detection is

used to prevent a rogue PC program or another module from “stepping on” the NCM time slot and

bringing down the entire NCM path. If enabled, both the local input(s) and T1 receive inputs will

monitor for rogue activity. The local input port is squelched for at least 2 minutes once a continuous

data stream lasting for greater than 60 seconds is detected. The T1 receive data is squelched for 2

minutes once a continuous data stream greater than 64 seconds is detected on the bus. The T1 rogue

threshold is set intentionally higher than the local port to prevent all the nodes from reacting to a rogue

at any of the local ports.

After all settings are made on the General page (Figure 12), click on the Address tab to get to the

Address window as shown in Figure 14.

The Address window has two major selections, CM Address Passing and Local CM Address. Both of

these settings apply to NMS mode only. Set the local CM address first.

Figure 14. NCM Address Configurations and Status window for Node 1

Local CM Address

The “Local CM Address” for the NCM module must be set to the same address as the local Common

Module (CM3B, CM3C, CM3R, CM6B, or CM4). The NCM supports addresses from 1 to 999 (see

note below) and is set by using the up and down arrows in the hundreds, tens and units boxes as shown

in Figure 14. For example, if your CM4 is set to Address 351, the “CM Address” of the NCM must be

set to 351. The next step is to set CM Address Passing.

NOTE

The CM3B, CM3C and CM6B support addresses from 1 to 99. The CM4 and CM6B support

addresses from 1 to 500.

CM Address Passing

The CM Address Pass setting controls the range of addressed messages that are allowed to pass from

the NCM to the local common module in accordance with the table below. There are four CM Address

Passing settings as follows, Any, = =, > =, and < = .

CM Address Pass

Description

Any

= =

> =

< =

Will pass any messages regardless of the “Local CM Address” setting of the NCM.

Messages without address headers are also passed.

Will only pass messages with addresses equal to the “Local CM Address” setting of

the NCM

Will only pass messages with addresses greater than or equal to the “Local CM

Address” setting of the NCM

Will only pass messages with addresses less than or equal to the “Local CM Address”

setting of the NCM

After all settings are made on the Address page, (Figure 14), click on the Serial Port tab to get to the

Serial Port window as shown in Figure 15.

Port 2 Enable

For the interfaces that physically have two ports, port 2 can be enabled or disabled. The MA402I has

two RS232 ports, one on port 1 and one on port 2. The MA490 has one RS485 port on port 1. The

MA490 has one Ethernet port on port 1 and one RS232 port on port 2. For example if you are using an

MA402I, you can disable port 2 if it is not being used.

Loopback

In normal operation all loopbacks are disabled. Loopback settings are used for troubleshooting

purposes. There are four loopback settings as follows:

1. Disable all loopbacks

2. Enable port 1 and port 2 equipment loopback

3. Enable port 1 payload loopback

4. Enable port 2 payload loopback

If the MA485 is configured as two wire, it does not support loopback.

After all NCM parameter selections have been made they must be written to the NCM card in the

network. This is done by using the “WRITE” operation as described in Section 7 of The IMUX 2000

Instruction Manual.

TROUBLESHOOTING

If there is an apparent malfunction, first check that the configuration is appropriate for the transmission

system in use, and that transmit and receive configurations are identical.

Problems may occur at the common equipment or facility level that may affect the operation of this

module. Refer to the “Maintenance” section in your multiplexer manual for system analysis

procedures.

REMOTE CONTROL USING SCL COMMANDS

When installed in an IMUX 2000 remote controllable shelf, the NCM module can be operated under

local or remote control. When under remote control, certain configuration parameters can only be

changed through the RS-232 remote port on the multiplexer. The remote interface for this module

involves two codes: a “P” (parameter) code, and an “S” (status) code. See the IMUX 2000 instruction

manual for more information on the remote control interface.

The NCM module reports itself as a “Type 117” module.

“P” CODES

“P” codes, when used in the parameter field on a “SET” command, allow the user to set certain

parameters on the module by remote control, just like setting the switches on a module under local

control. “P” codes also appear in the response to a “CONFIG?” query, showing the current parameter

settings on the module.

There are ten “P” codes for the NCM module: P01 through P10. Each of these P codes can be a

decimal number from 0 to 255, which can also be represented as an eight-digit binary number (in

parenthesis). The binary representation is more useful for setting and interpreting the “P” codes, since

each binary digit (0 or 1) corresponds to the ON or OFF setting for a particular switch on the module.

Table 6 describes the meanings of the “P” codes for the NCM module.

A typical NCM module response to a “CONFIG?” query looks like this:

* OK

NOTE

When using binary numbers with a SET command, they must be preceded by the letter “B” as

shown in the following example:

<MULTIPLEXER ADDRESS>:<CARD ADDRESS>:SET:P1 = B00000011;

Besides using the P code, it is also possible to turn module service on or off by sending one of the

following in the parameter field with a SET command:

SRVC = ON

SRVC = OFF
