About Hotwire 8777 and 8779
TDM SDSL Units
1
TDM SDSL Overview
®
Hotwire Time Division Multiplexer Symmetric Digital Subscriber Line (TDM
SDSL) products maximize customer service areas by varying the DSL line rate.
This ensures symmetric DSL connectivity over a wide range of telephone line
distances and transmission line qualities. Hotwire 2-wire TDM SDSL products
transmit data over 14,000 feet (4.6 km) at rates up to 2.048 Mbps.
Hotwire products support autorate. Units first synchronize to the highest line rate
that the 2-wire loop supports, then automatically configures the unit to the highest
multiple of 64 Kbps supported by that line rate. Eight line rates are available. At all
rates, an 8 Kbps management channel is available, which enables functions such
as firmware downloads to remote units. Units can also be configured manually to
full or fractional T1 or E1 rates.

User Interface Access
You can communicate with the asynchronous terminal interface (ATI) using one of
the following methods:
Direct connection through the Management Serial port of the DSLAM (locally
or via an external modem).
Telnet session using a Network Management System (NMS) connected to a
LAN/WAN port on the DSLAM.
Telnet session through the Embedded Operations Channel (EOC).
NOTE:
Only one asynchronous terminal interface session can be active at a time, and
another user’s session cannot be forced to end. To automatically log out a
Security can limit ATI access in several ways. To set up security or a login ID, refer

Cross-Connecting Ports
4
Overview
Configuration of the cross-connections consists of the following steps:
❑ Determine how the ports will be connected and configured.
❑ On the Network Interface Options screen, enable the DSL ports that will be in
the cross-connection if necessary. The ports are enabled by default.
❑ On the DSX-1 or G.703 Interface Options screen, enable the DSX-1 or G.703
ports that will be in the cross-connection.
For G.703, specify whether Time Slot 16 is used for signaling (voice mode).
❑ On the System Clock screen, configure the system clock.
❑ On the Cross-Connect Mode screen:
— Define all DS1 Bypass ports.
— Define all DS1 Cross-Connect ports.
— Define all DS0 Cross-Connect ports.
❑ On the Assign Time Slots screen, configure the DS0 cross-connections.
This chapter describes the use of the Cross-Connect Mode and Assign Time Slots
configuration options presented on the other screens.
Examples in this chapter show screens for DSX-1 models. The principles of
cross-connection are the same for G.703 models.
IMPORTANT:
All DSL time slots are available for cross-connect regardless of DSL line
rate, but all time slots are available for data transport only if the DSL line
rate is the full rate (1552 for DSX-1 or 2064 for G.703). Configure only the
time slots intended for use.

4. Cross-Connecting Ports
Determining the Configuration
The Hotwire cross-connect system allows you to connect the DSX-1 or G.703
ports to the DSL ports in a variety of ways:
DS1 Bypass mode – The entire DSX-1 or G.703 interface is connected to the
DSL interface.
DS1 Cross-Connect mode (8777) – The entire DSX-1 interface is connected
to the DSL interface through cross-connect circuitry. Ports can be switched
through software.
DS1 Cross-Connect mode (8779) – The entire G.703 interface can be
connected to any DSL or G.703 interface. The entire DSL interface can be
connected to any DSL or G.703 interface through cross-connect circuitry.
Ports can be switched through software.
DS0 Cross-Connect mode (8777) – Any time slot of any DSX-1 interface can
be connected to any time slot of any DSL interface. Time slots can be
individually allocated for voice or data.
DS0 Cross-Connect mode (8779) – Any time slot of any DSL interface can
be connected to any time slot of any G.703 or DSL interface. Any time slot of
any G.703 interface can be connected to any time slot of any G.703 or DSL
interface. Time slots can be individually allocated for voice or data.
The example below shows a DS0 cross-connection between DSX-1
Ports 1 and 2. DSX-1 Port 1 is dedicated to voice and Port 2 to data.

NOTES:
— Although the example shows ports dedicated to voice or data, a port can
be configured for both voice and data.
— For G.703 ports using Common Channel Signaling (CCS) that are in DS0
Cross-Connect mode, you must explicitly configure the cross-connections
for Time Slot 16 and related time slots.
Cross-Connection Worksheets, contains a skeleton diagram for this purpose.
It also contains worksheets for documenting your time slot cross-connections
before you begin to configure them.

IP Addressing
5
Selecting an IP Addressing Scheme
Your IP addressing scheme depends in part whether the management card
controlling the chassis is running IP Conservative software.
Configurations Not Running IP Conservative Software
In a configuration not running IP Conservative software, the NTU’s network
interface IP address is assigned through the peer IP address of the LTU’s Network
Interface menu.
The termination unit is assigned an IP address and subnet through the DSLAM’s
Configuration → DSL Cards → Set IP Address menu. Once the address is
assigned, you can use the ATI to assign:
Peer IP addresses to the DSL ports. These addresses are used as the IP
addresses of the remote units, and must be in the same subnet as the DSLAM

5. IP Addressing
All Configurations
The NTU obtains its IP address when the PPP link is established over the EOC.
Use the ATI to assign:
An IP address for the TFTP server you wish to use to upload and download
and Configurations Using TFTP, and the documentation for your TFTP server.
Review the following information in preparation for selecting an IP addressing
scheme.
Any legal host address is allowed for a given subnet. The address choice
within the subnet is arbitrary.
A single route to a subnet is all that is needed to reach every device on a
subnet. The unit’s routing table supports a maximum of 20 routes.
IP Addressing Example
Figure 5-1, Peer IP Address Assignments, shows IP addressing in a typical
network. Note that the Peer IP Address:
Refers to the IP address of the unit configured as an NTU.

Controlling SNMP Access
There are three methods for limiting SNMP access.
Assign SNMP community names and access types.
Limit SNMP access through validation of the IP address of each allowed
SNMP manager.
Assigning SNMP Community Names and Access Types
The unit can be managed by an SNMP manager supporting SNMP. The
community name must be supplied by an external SNMP manager accessing an
object in the MIB.
To define SNMP community names, follow this menu selection sequence:
Main Menu→ Configuration→ Current Configuration→
Management and Communication→ General SNMP Management
Enable SNMP Management.
Assign the SNMP community names of the SNMP Managers that are allowed
to access the unit’s Management Information Base (MIB).
Specify Read or Read/Write access for each SNMP community name.
Limiting SNMP Access through the IP Addresses of the Managers
The unit provides an additional level of security through validation of the IP
addresses.
The SNMP Management option must be enabled. To control SNMP access with IP
addresses, follow this menu selection sequence:
Main Menu→ Configuration→ Current Configuration →
Management and Communication→ SNMP NMS Security
Options. The SNMP access can be limited by:
Enabling NMS IP address checking.
Add each IP address and access level.
NOTE:
Do not change or delete the IP address or access level of the NMS performing
the sets or enable IP address checking prior to adding the NMS to the table.

Remote Send Line Loopback
The local unit initiates this test by sending a line loopback Up or Down command
to the remote unit for 10 seconds. When the remote unit detects the loopback Up
command, it puts itself in line loopback and lights the front panel Test LED. The
remote unit remains in loopback until it receives a loopback Down command or the
remote unit’s test timeout value is exceeded. The Send Line Loopback tests both
units. External equipment can be used to verify the link.

All ports configured as system clock sources must be traceable to the same clock
reference. Ports in a cross-connect configuration that are not providing timing
themselves receive their timing from the system clock reference. All ports in a
cross-connect configuration are therefore synchronized to the system clock
reference.
On an LTU, the system clocks may be sourced from the DSX-1/G.703 interface
which is generating timing, or from the internal oscillator on the card (providing a
Stratum 4 reference). Typically, the primary clock source is a DSX-1/G.703 port
which is being used in a cross-connection. The LTU secondary clock sources are
restricted to G.703 ports configured for Bypass mode. On an LTU when the
system clock is configured for something other than internal, DSX-1/G.703 ports
configured for Bypass mode and internal timing will use the user-specified clock as
their reference.
On an NTU, the system clock may only be sourced from DSL ports being used in a
cross-connection. If all ports on an NTU are configured for Bypass mode, no
configuration for system clock is required (primary and secondary clock should
remain set to their default values).

A. Configuration Options
When a system clock source fails or is misconfigured, an alarm is reported.
Secondary clock failures are not reported unless the primary clock has also failed.
When the primary clock fails, clocking is switched to the secondary clock source, if
available. If a secondary clock is not available, the clock switches to secondary
holdover mode. In holdover mode, the system attempts to generate timing which is
consistent with the last clock reference. A switch is made back to the primary clock
when it becomes available. Holdover mode is meant to be used for short durations
while network synchronization is temporarily disrupted. The switch back to
primary/secondary clock is made when they become available again.

Using the Worksheets
The following worksheets are designed to help plan, visualize, and configure a
cross-connection. Time slot assignment worksheets are supplied to represent a
connection from the viewpoint of the DSX-1 or G.703 ports, or the associated DSL
ports. The unit can be configured using either viewpoint, so it may not be
necessary or useful to fill in all the worksheets.
Use the completed port connection diagram and time slot assignment worksheets
to configure the cross-connection using the Cross-Connect Mode and Assign Time
cross-connection.
