Handling Energized Products
General Safety Practices
Do not touch or tamper with the power supply when the power cord is connected. Line voltages may
be present inside certain products even when the power switch (if installed) is in the OFF position or a
fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous,
energy hazards may still exist.
Before working on equipment connected to power lines or telecommunication lines, remove jewelry
or any other metallic object that may come into contact with energized parts.
Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is
provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug
is provided on the product, it should be connected to the protective earth at all times, by a wire with a
diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks
and cabinets.
Always make the ground connection first and disconnect it last. Do not connect telecommunication
cables to ungrounded equipment. Make sure that all other cables are disconnected before
disconnecting the ground.
Connection of AC Mains
Make sure that the electrical installation complies with local codes.
Always connect the AC plug to a wall socket with a protective ground.
The maximum permissible current capability of the branch distribution circuit that supplies power to
the product is 16A. The circuit breaker in the building installation should have high breaking capacity
and must operate at short-circuit current exceeding 35A.
Always connect the power cord first to the equipment and then to the wall socket. If a power switch is
provided in the equipment, set it to the OFF position. If the power cord cannot be readily
disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency
switch is installed in the building installation.
Connection of DC Mains
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the
ground. Any single pole can be externally grounded.
Due to the high current capability of DC mains systems, care should be taken when connecting the DC
supply to avoid short-circuits and fire hazards.
DC units should be installed in a restricted access area, i.e. an area where access is authorized only to
qualified service and maintenance personnel.
Make sure that the DC supply is electrically isolated from any AC source and that the installation
complies with the local codes.
The maximum permissible current capability of the branch distribution circuit that supplies power to
the product is 16A. The circuit breaker in the building installation should have high breaking capacity
and must operate at short-circuit current exceeding 35A.
Before connecting the DC supply wires, ensure that power is removed form the DC circuit. Locate the
circuit breaker of the panel board that services the equipment and switch it to the OFF position. When
connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the
positive pole and last the negative pole. Switch the circuit breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved should be incorporated in
the building installation.

Ports whose normal operating voltage is within the
limits of SELV, on which overvoltages from
telecommunications networks are possible.
FXS (Foreign Exchange Subscriber)
TNV-2 Telecommunication Network Voltage-2:
Ports whose normal operating voltage exceeds the
limits of SELV (usually up to 120 VDC or telephone
ringing voltages), on which overvoltages from
telecommunication networks are not possible. These
ports are not permitted to be directly connected to
external telephone and data lines.
FXO (Foreign Exchange Office), xDSL TNV-3 Telecommunication Network Voltage-3:
(with feeding voltage), U-Interface
Ports whose normal operating voltage exceeds the
ISDN
limits of SELV (usually up to 120 VDC or telephone
ringing voltages), on which overvoltages from
telecommunication networks are possible.
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a
qualified safety engineer.
Always make sure that the equipment is grounded before connecting telecommunication cables. Do
not disconnect the ground connection before disconnecting all telecommunications cables.
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.
Extra caution should be exercised during thunderstorms.
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The
earthing and bonding of the ground connections should comply with the local codes.
The telecommunication wiring in the building may be damaged or present a fire hazard in case of
contact between exposed external wires and the AC power lines. In order to reduce the risk, there are
restrictions on the diameter of wires in the telecom cables, between the equipment and the mating
connectors.

Order from: Cutter Networks
Ph:727-398-5252/Fax:727-397-9610
Caution
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.
Attention
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de
télécommunications 26 AWG ou de section supérieure.
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such
cases, a notice will be given in the installation instructions.
Do not attempt to tamper with any carrier-provided equipment or connection hardware.
Electromagnetic Compatibility (EMC)
The equipment is designed and approved to comply with the electromagnetic regulations of major
regulatory bodies. The following instructions may enhance the performance of the equipment and will
provide better protection against excessive emission and better immunity against disturbances.
A good earth connection is essential. When installing the equipment in a rack, make sure to remove all
traces of paint from the mounting points. Use suitable lock-washers and torque. If an external
grounding lug is provided, connect it to the earth bus using braided wire as short as possible.
The equipment is designed to comply with EMC requirements when connecting it with unshielded
twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for
high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on
certain cables. In such cases, special instructions are provided in the manual.
Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.
The compliance of the equipment with the regulations for conducted emission on the data lines is
dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss
(LCL).
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary
protection against surges on the data lines. Primary protectors should be provided in the building
installation.
The equipment is designed to provide adequate protection against electro-static discharge (ESD).
However, it is good working practice to use caution when connecting cables terminated with plastic
connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before
connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist
strap.

Installing the RIC-E1/R card.
5.1 ASM-MN-214 Card Cage
The ASM-MN-214 card cage contains one or two power supplies and up to
14 plug-in cards. The card types can be RIC-E1/R or other RAD rack version
modems/converters – any combination of up to 14 plug-in cards.
For each of the 14 cards, the rear panel (see Figure 5-1) contains a male connector
for the terminal block and a DB-25 connector. A protection cover protects the
terminal block connectors.
Line Connector
The line is to be attached to the rear panel terminal block connectors
(see Figure 5-1). It contains screws for connecting the transmit and receive pairs
and ground, if present. When operating RIC-E1/R with unbalanced E1 interface,
use a CIA/TB-BNC/214 adapter, which converts the terminal block connector into
two coaxial BNC connectors (see Figure 5-1).
The ASM-MN-214 card cage is also available with BNC coaxial unbalanced or
RJ-45 balanced line connectors.
DTE Connector
The 25-pin D-type female interface connector provides all interface signals for the
digital interfaces. Units with X.21 or V.35 interface require an external mechanical
adapter. Two optional interface attachments, CIA/X21/1 and CIA/V.35/1, can be
ordered separately from RAD. CIA/X.21/1 converts one DB-25 connector to an
X.21 15-pin connector. CIA/V.35/1 converts one DB-25 connector to a V.35
34-pin connector.
V.36 converter cards are supplied with a RAD adapter cable CBL-530/449F, which
converts between the DB-25 connector and a V.36 37-pin connector.

5.2 Power Supply
Power is supplied to the RIC-E1/R card from the ASM-MN-214 power supply via
the chassis. Each RIC-E1/R card has two fuses (F5 and F6), which protect the entire
system against power failure resulting from a short circuit in one card. The rating of
the fuses is 500 mA, 250V, slowblow (see Figure 5-6).
The ASM-MN-214 card cage can accept both AC or DC power supplies. LED
indicators located on the ASM-MN-214 front panel (see Figure 5-5) show activity
when the power supply is connected to the mains plug. The power supply
supports the full card cage with any combination of cards.
AC Supply
DC Supply
The AC power supply of the ASM-MN-214 is 100, 115, or 230 VAC, ±10%,
47 to 63 Hz.
The DC power supply is -48 VDC (-36 to -72 VDC) or 24 VDC (18 to 32 VDC). It
uses a DC/DC converter module to provide the power required for the cards.
Power Supply with Redundancy
This special ordering option is equipped with two separate power supplies,
operating together and sharing the load of the whole card cage. If either of the
power supplies fails, the other one will continue to supply power to the full card
cage.
Two LED indicators show activity of each power supply. They should both light
when mains power is provided.
Note
It is possible to combine AC and DC power supplies in the same cage.

4. When operating RIC-E1/R with unbalanced interface, use CIA/TB-BNC/214
adapter, which converts the terminal block connector into two coaxial BNC
connectors.
5. If required, attach the appropriate CIA (CIA/X.21/1, CIA/V.35/1, CIA/ETH) or
CBL-530/449F adapter cable to the DB-25 connector on the card cage rear
panel.
6. Connect the DTE cable to the DB-25 connector, other side of CIA or adapter
cable (depending on your version of the card interface).
7. Connect power to the ASM-MN-214 card cage:
ꢀ To connect AC power, connect the power cable to the mains supply.
ꢀ To connect DC power, refer to DC power supply connection supplement
of the ASM-MN-214 installation and operation manual.
The ASM-MN-214 card cage has no power switch. Operation starts when the
power is applied to the rear panel POWER connector. When applying power,
first connect the plug of the power cord to the ASM-MN-214 POWER
connector and then to the mains (outlet).

B.1 Introduction
IR-ETH is an interface module for RAD products, which is used for converting the
Ethernet (10BaseT or 10Base2) electrical levels to the TTL levels. It also converts
the Ethernet protocol to HDLC to enable long-distance transmission and avoid the
Ethernet collision limitation.
IR-ETH includes an internal, self-learning Ethernet bridge, which enables a high
performance link between two Ethernet segments at a low transmission rate. The
low-speed HDLC transmission is sent over the G.703 link.
Figure B-1 shows a typical application using RIC-E1 with IR-ETH module.

C.1 Introduction
The IR-ETH/V interface module replaces the IR-ETH/QN interface module.
The IR-ETH/V has improved functionality, however, it should be noted that there
are now two priority queues available. IR-ETH/V includes a high performance
self-learning Fast Ethernet bridge, which is connected to the LAN via a single
10BaseT or 100BaseT port, operating in full or half duplex and providing simple
and cost-effective interconnection between 10/100BaseT LANs. The IR-ETH/V
interface module also supports IEEE 802.1p frames and IEEE 802.1q frames,
enabling VLAN applications.
The module automatically learns MAC addresses of the LAN to which it is
connected. Its LAN table stores up to 2,048 addresses with 5-minute automatic
aging. Filtering and forwarding is performed at wire speed.
Figure C-1 shows a typical application using RIC-E1 with IR-ETH/V module.

Backpressure and Flow Control
DIP switch SW1/4 enables or disables both backpressure and flow control.
When the IR-ETH/V is set to half duplex, backpressure is active, and when the IR-
ETH/V is set to full duplex, flow control is active.
Note
Full duplex flow control activation requires autonegotiation to be enabled.
Backpressure is the term given when the buffer is filled from the LAN faster than it
is able to transmit to the WAN. In order to prevent packet loss, collisions are
forced into the LAN, which causes the link partners to go into backoff before
attempting to retransmit. Reducing, in effect, the traffic coming through the
interface.
Flow control is active only in full duplex mode. When the buffer is filled from the
LAN faster than it is able to transmit to the WAN, pause frames are sent to the
LAN, ordering the LAN to stop for a time interval indicated by the pause frame
until transmission starts again.
Note
To use the flow control option, the link partners (switches etc.) should support flow
control.

D.1 Introduction
IR-IP is a high-performance miniature IP router based on RAD's unique IP router
chip, the ChipRouter.
IR-IP works by taking each Ethernet frame from the LAN and determining whether
the IP packet is destined for the IP net on the Ethernet LAN. If not, IR-IP forwards
the packet to the WAN (E1) link. IP packets received from the WAN link are
automatically forwarded to the LAN if the IP net matches.
IR-IP includes hardware filters which handle all filtering operations at wire speed
from both LAN-to-WAN and WAN-to-LAN, without dropping a single packet.
Filtering and forwarding are performed at the maximum rate of 35,000 and
30,000 frames per second (wire speed), respectively. The buffer can hold
256 frames of maximum size of 1534 bytes and a throughput latency of one
frame.
IR-IP is available with 10BaseT (UTP) interface and is fully IEEE 802.3/Ethernet V2
compliant. The IR-IP interface can also operate in full duplex Ethernet
applications.
RIC-E1 equipped with IR-IP can be used as a Frame Relay Access Device (FRAD)
with an integral IP router. RFC 1490 is supported for a single DLCI on the E1 link.
Detection of the DLCI and the maintenance protocol is performed automatically.
This allows the IR-IP to be used as the termination unit of IP services over Frame
Relay at the customer premises, opposite a Frame Relay switch in the backbone.
Alternatively, Point-to-Point Protocol (PPP) can be run on the WAN link with
automatic negotiation on power-up, as well as support for PAP and CHAP
authentication. With this feature, the IR-IP can operate opposite any PPP
compliant access server or backbone router.
IR-IP supports HDLC, which is especially important for broadcast and multicast
applications where bandwidth overhead is critical.
IR-IP supports IP multicast at wire speed, making it suitable for any multicast
environment including high speed downstream environments, such as satellite and

ꢀ Ping utility, for checking IP connectivity.
The management subsystem of the IR-IP interface module is a separate,
independent entity. The communication with the IR-IP management subsystem is
made through the local LAN interface connector of the IR-IP module, designated
10BASE-T, using the Telnet protocol. Passwords can be used to prevent
unauthorized access.
Accessing the IR-IP Management Subsystem
The IR-IP interface module must be configured in accordance with the specific
requirements of the user’s application before it can be used in the user’s network.
As a result, it is not possible to supply default parameters to enable IR-IP to start
service without any preliminary configuration.
Therefore, to enable the user to establish Telnet communication and configure
IR-IP, IR-IP is delivered with a factory-default set of parameters. The default
parameters are automatically used:
•
Before IR-IP is configured by the user, e.g., when a new RIC-E1 with IR-IP
interface module is put into operation
•
After the user’s configuration parameters have been erased.
When the factory-default parameters are used, the ERR indicator located on the
RIC-E1 rear panel, near the IR-IP Ethernet interface connector flashes rapidly
(about three times per second). The flashing of the ERR indicator also serves as a
warning to the user that the IR-IP WAN (E1) interface does not send, nor does it
receive packets, and therefore IR-IP can be accessed only from the LAN.
After configuring IR-IP, it starts normal operation and routes the traffic in
accordance with the user-selected configuration parameters.
To change the parameters of an already-configured IR-IP, establish communication
from a Telnet host using the assigned IP address.
Default IP Communication Parameters
The factory-default IP communication parameters of the interface module are:
•
•
The default IP address of the IR-IP Ethernet port is 192.168.205.1, and the
default IP subnet mask is 255.255.255.252.
The port will accept IP communication only from the IP address
192.168.205.2. Therefore, as long as the factory defaults are in effect, you
must assign this address to the Telnet host used to configure IR-IP.
Using the IP learning mechanism, as explained below you can change the default
parameters.

Rescue Configuration
In case you have forgotten the IP address or the Telnet password, you will
generally not be able to view or modify the IR-IP configuration. The Rescue feature
allows you to overcome this problem.
ꢀ
To allow the IR-IP configuration:
1. Remove RIC-E1/R from the chassis.
2. Set section 6 of the DIP switch to ON.
3. Insert RIC-E1/R back into the chassis.
As soon as RIC-E1/R is powered on, it will respond to the default IP address
and permit entering configuration screens without password protection. All
the other configuration parameters remain unchanged.
4. After setting the parameters to desired values, remove RIC-E1/R from the
chassis and restore section 6 of the DIP switch to OFF.
D.5 Performing Preliminary Configuration
The software necessary for performing all the management and configuration
functions is stored in the IR-IP interface module, and therefore you only need a
regular Telnet host to perform all the activities described in this appendix.
A Telnet host is any computer, e.g., an IBM PC or compatible that fulfills the
following minimum requirements:
•
•
A standard 10BaseT Ethernet interface
A TCP/IP protocol stack, and therefore is capable of supporting IP
communication through the Ethernet interface
•
•
Telnet client software
A ping utility.
Outline of Preliminary Configuration
ꢀ
To perform the preliminary configuration procedure:
1. Connect the Telnet host to the IR-IP interface module.
2. Configure the Telnet host to enable communication with the IR-IP interface
module using the default IP parameters.
3. Establish communication with IR-IP and assign the prescribed IP address to its
LAN interface.
4. Establish again communication with IR-IP and continue the preliminary
configuration in accordance with the Quick Setup Menu section below.

Appendix D IR-IP Interface Module
Connecting the Telnet Host
Before starting the management and configuration activities, it is necessary to
establish IP communication between your Telnet host and the IR-IP interface
module. For this purpose, it is necessary to provide a communication path.
Because of the method used to assign an IP address to IR-IP Ethernet port, it is
recommended to connect the Telnet host directly to the IP router 10BASE-T
connector. This is made by connecting an Ethernet cross cable between the
Ethernet connector of the Telnet host and the IP router connector.
However, you may also connect through a common LAN: in this case, connect
your Telnet host and IR-IP to Ethernet hub ports using straight cables.
Preliminary Telnet Host Configuration
You can use the IP learning mechanism to configure the IP communication
parameters of the IR-IP LAN interface. In this case, skip to the Assigning the Router
LAN Interface Address section below.
If you prefer to use the factory-default parameters to establish IP communication
between your Telnet host and IR-IP, configure the Telnet host as follows:
1. Temporarily configure the host IP address as 192.168.205.2.
2. The initial destination IP address to be used by the host is 192.168.205.1.
Note
The first step in the preliminary configuration process is to assign the desired IP
address to the LAN interface of the IR-IP interface module.
After an IP address is assigned and saved, you must change the destination IP
address of the Telnet host to the new address, otherwise it is not possible to
continue the configuration process. At the same time, you can also change the
temporary IP address assigned to the host (192.168.205.2) back to its permanent
address.
Assigning the Router LAN Interface Address
The IP address of the IR-IP LAN interface must be configured as part of the
preliminary configuration process. To simplify this process, IR-IP includes a simple
and convenient IP address learning mechanism.
The IP address can be configured and changed at any time, even after the
complete IR-IP configuration process has been performed, because it does not
affect other configuration parameters. Moreover, the IP subnet mask is
automatically adapted to the new IP address.
IP Learning Mechanism
To simplify the configuration process, IR-IP has a special mechanism for
configuring the IP address of its LAN interface. Setting section 1, called IP address
learning, of the IR-IP DIP switch (Figure D-4) to ON enables this mechanism.
For RIC-E1/R the IP learning procedure is performed by pressing the IP LEARN
pushbutton on the card panel.
The IP learning mechanism enables IR-IP to learn its LAN interface IP address by
receiving frames sent by a ping utility to the prescribed LAN IP address.
Note
To use the IP learning mechanism, you do not need to know the current address of
IR-IP LAN interface, but only the prescribed IP address.

RIC-E1 Installation and Operation Manual
The IP address is actually retrieved from the ARP frames sent during pinging to
locate the ping destination, not from the ping frames.
To ensure that the process is correctly performed, it is recommended to check the
contents of the ARP table before starting the ping utility, to make sure that it does
not contain the address to be assigned to the IP router LAN interface.
ꢀ
To view and edit the ARP table contents:
If the Telnet host you are using runs under Microsoft Inc. Windows™ 95, 98 or
NT, use the following procedure to view and edit the ARP table contents:
1. Display the table using the arp -acommand.
2. If the table includes the intended IP address, remove it from the table using
the arp -dcommand.
If for some reason the IP learning process does not succeed, before repeating it
make sure to remove the IP address from the table.
Assigning a LAN IP Address to a New IR-IP
The following procedure enables you to configure the LAN IP address of a new
IR-IP router, i.e., a router using the default parameters (see the Accessing the IR-IP
Management Subsystem section above).
If RIC-E1 is already operating, skip Step 2 in the following procedure.
ꢀ
To configure the IP router LAN address:
1. Make sure the preparations described above have been completed, including
the configuration of the ping utility.
2. Turn RIC-E1 on and monitor the IP router indicators:
ꢀ The INT (LINK for RIC-E1/R) indicator turns on
ꢀ The ERR indicator lights steadily for approx. 15 seconds, and then starts
flashing at a rapid rate (about three times per second).
If the ERR indicator turns off, skip to the What to Do If ... section below.
3. Set section 1 of IR-IP DIP switch to ON or push the IP LEARN pushbutton on
the RIC-E1/R panel.
The ERR indicator starts flashing faster (approximately four times a second).
4. Send a ping to the new address to be used by IR-IP. A confirmation should be
received after the third ping: after the confirmation, the flashing will slow
down to approximately twice a second.
If your host does not begin to receive ping replies after three unsuccessful
attempts, skip to the What to Do If ... section below.
5. Return section 1 of the IR-IP DIP switch to the OFF position or push IP LEARN
again to return the button to its initial position.
The ERR indicator must turn off.
At this stage, the communication with IR-IP router is lost, because its IP address
has been changed. Therefore, you must reconfigure the destination IP address of
the Telnet host. If you wish, you may also change the temporary IP address
assigned to the host (192.168.205.2) back to its permanent address.

RIC-E1 Installation and Operation Manual
Appendix D IR-IP Interface Module
After changing the destination IP address of the Telnet host, it is recommended to
turn RIC-E1 off for a few seconds and then back on, before continuing the
configuration of the IP router in accordance with the Quick Setup Menu section
below. At this time, in Step 2 the ERR indicator turns off after the 15-second
interval.
Changing the LAN IP Address of a Configured IR-IP
The LAN IP address of an already-configured IR-IP can be changed while it
operates, this means it is not necessary to turn RIC-E1 off before starting the
configuration procedure. Note however that the IP traffic flow through IR-IP will
be disrupted until the other stations in the IP network learn the new address.
To change the LAN IP address of an already-configured IR-IP, use the procedure
described above for a new IR-IP with the following differences:
1. Configure the destination address of the ping utility to the new LAN interface
IP address. It is not necessary to change the Telnet host source address.
2. When ready, set section 1 of the IR-IP DIP switch to ON or push the IP LEARN
pushbutton on the RIC-E1/R panel.
The ERR indicator starts flashing faster (approximately four times a second).
3. Perform Steps 4, 5 of the procedure used for a new IR-IP.

LAN IP Address
Used to enter the IP address for the IP router LAN interface. This is the address to
which nodes connected to the local LAN send packets addressed to the WAN.
LAN IP Mask
Used to enter the IP subnet mask. The IP router supports a maximum of 254 hosts
on the LAN, therefore you must use Class C subnet masks. The basic subnet IP
mask for Class C addresses, which supports the maximum possible number of
hosts, 254, is 255.255.255.0. To help you understand the selection of IP subnet
masks, Figure D-9 provides a configuration example for a LAN with 6 nodes: the IP
subnet mask for a 6-node IP network is 255.255.255.248.

WAN IP Address
Used to enter the IP address for the IR-IP WAN interface, i.e., the IP address to be
used by IP hosts on the WAN to reach this IR-IP interface module.
If the WAN IP Address field remain blank, IR-IP operates in the Unnumbered
Router Mode.
WAN IP Mask
Used to enter the IP subnet mask for the WAN interface.
Default Gateway
Operation without Default Gateway
The IP interface module is intended to enable the extension of LANs through the
RIC-E1 E1 link. Therefore, its default routing operation is different from the default
routing operation of standard IP routers:
•
IR-IP forwards packets with destinations not located on the local LAN through
the WAN interface
•
Packets received from the WAN interface and destined to hosts located on the
local LAN are forwarded to the LAN; other packets are discarded.
The default operation is used when the Default Gateway field is blank.

Appendix D IR-IP Interface Module
Operation with Default Gateway
You can instruct IR-IP to send packets with destinations not located on the local
LAN to a specific router, which is called the default gateway. The default gateway
must be connected to the local LAN.
To use this option, enter the IP address of another router attached to the local LAN
in the Default Gateway field.
Note
It is very important to obtain the correct parameters from the system administrator
or ISP. The most common problem when establishing an IP connection is incorrect
configuration of IP parameters and default gateway. Do not try to guess these
parameters.
DHCP Relay
IR-IP can operate as a DHCP relay for computers on its LAN. In this mode, the
user does not need to configure the IP addresses and other related parameters for
the PCs on the LAN: they receive the configuration from the DHCP server via the
IR-IP module.

Read Protocol from DIP Switches
Selecting YES for this parameter forces IR-IP router card to use the WAN protocol
selected by section 2 of its DIP switch: PPP or Frame Relay.

RIC-E1 Installation and Operation Manual
Appendix D IR-IP Interface Module
D.13 Erasing User’s Configuration
The user-defined configuration parameters are stored in the IP router card flash
memory. After the user-defined configuration parameters are erased, the IP router
card automatically loads the factory-default parameters.
You may want to erase the current configuration parameters:
1. Before IR-IP is prepared for operation in a new application.
2. When you cannot configure IR-IP because its current LAN-interface IP address
and/or the Telnet password, are not known.
ꢀ
To erase the user’s configuration:
1. Turn RIC-E1 off.
2. Set all the four sections of the IR-IP DIP switch (Figure D-4) to ON.
3. Turn RIC-E1 on and monitor the ERR indicator: it must turn on and start
blinking.
4. While the ERR indicator is blinking (within 15 seconds), set sections 1 and 2 of
the DIP switch to OFF.
When the ERR indicator stops blinking and lights steadily, the IP router
configuration becomes erased.
Note
If you do not set sections 1 and 2 to OFF within 15 seconds of power-up, the IP
router card ignores the setting of all the four sections to ON and starts normal
operation. In this case, it is recommended to turn the RIC-E1 off and then back on.
To abort the whole operation, turn RIC-E1 off, return all the four-switch section to
the desired positions, and then turn the RIC-E1 on again.
5. Turn RIC-E1 off, and the return all the four sections of the DIP switch to the
desired positions.
D.14 Erasing IR-IP Software
You may erase the IR-IP application software, without erasing the user-defined
parameters.
After the application software is erased, IR-IP starts its TFTP server application, and
waits for the downloading of software by a TFTP client connected to its LAN
interface. The procedure to be used to download the application software in this
case is also described below.
You may want to erase the application software if the downloading of new
software using the Device Control menu (see Figure D-19) fails, and the IP router
card does not function properly.

ꢀ
To erase the application software:
1. Turn RIC-E1 off.
2. Set all the four sections of IR-IP DIP switch to ON.
3. Turn RIC-E1 on and monitor the IP router ERR indicator: it must turn on and
start blinking.
4. While the ERR indicator is blinking (within 15 seconds), set sections 3 and 4 of
the DIP switch to OFF.
When the ERR indicator stops blinking and lights steadily, the IP router
configuration becomes erased.
Note
If you do not set sections 3 and 4 to OFF within 15 seconds of power-up, IR-IP
ignores the setting of all the four sections to ON and starts normal operation. In this
case, it is recommended to turn RIC-E1 off and then back on.
Alternately, to abort the whole operation, turn RIC-E1 off, return all the four
switches to the desired positions, and then turn RIC-E1 on again.
5. Turn RIC-E1 off, and the return all the four sections of the DIP switch to the
desired positions.
Downloading New Software
After erasing the application software, you can download new software from any
computer that can serve as a TFTP client.
To enable the downloading, IR-IP automatically activates its TFTP server
application with the following factory-default IP parameters:
•
•
IP address:
192.168.205.1
Subnet mask:
255.255.255.252.
Connect the computer serving as a TFTP client to the IR-IP 10BASE-T connector in
the way as a Telnet host used for preliminary configuration (see the Performing
Preliminary Configuration section). The computer IP parameters must be
configured as follows:
•
•
•
IP address
192.168.205.2
255.255.255.252
192.168.205.1
Subnet mask
Default gateway
ꢀ
To download new software:
1. If necessary, turn RIC-E1 off.
2. Set all the four sections of the IR-IP DIP switch to OFF.
3. Turn RIC-E1 on and monitor the ERR indicator: it must start flashing.
4. Connect the computer to the IP router LAN interface and configure its IP
parameters as explained above.
5. Run a standard TFTP client application on the Telnet host, and download the
appropriate software file.
If the download is successful, IR-IP starts using the new software.
If the downloading fails, repeat the download process.

E.2 Selecting the IR-X.21B Timing
IR-X.21B interface module supports two clock modes:
•
•
EXT (external)
INT/LBT (internal/receive).
You must set the IR-X.21B clock to match the timing you have selected for RIC-E1.
The clock settings are made via the JP2 jumper located on the IR-X.21B board, as
shown in Figure E-3.
JP2
Figure E-3. IR-X.21B Module Layout
EXT Clock Mode
The EXT clock mode is used in applications of X.21 networks where the system
timing is provided by the X.21 network. The IR-X.21B module has an internal
16-bit FIFO buffer to compensate for the phase delay introduced to the system by
the line delay between the two units. Figure E-4 illustrates the buffer connection
and the flow of the receive, transmit and clock signals.
When RIC-E1operates in the external clock, you must set the IR-X.21B JP2 jumper
to EXT.

INT/LBT Clock Mode
The INT/LBT clock mode is used in applications where the IR-X.21B side uses the
clock signal from the E1 link. This mode is used mainly when the attached
equipment has an X.21 interface, but no ability to produce clock signals. The
module has a 16-bit FIFO buffer to compensate for the phase delay introduced by
the X.21 device. Figure E-5 illustrates the buffer connection and the flow of the
receive, transmit and clock signals.
When RIC-E1 operates in the internal or receive clock, you must set the IR-X.21B
JP2 jumper to INT/RCV.
