About the Hotwire 8799 Line Card

TDM SHDSL Overview

Hotwire® Time Division Multiplexer Symmetric High-bit-rate Digital Subscriber Line (TDM SHDSL) 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.

TDM SHDSL line cards can transport data at full (2.048 Mbps) or fractional payload rates over a 2-wire, full-duplex circuit over varying distances based on the conditions of the 2-wire loop. Examples include support for router, multiplexer and PBX connections on 24 gauge (.5 mm) cable up to 15,000 feet (4.6 km).

The line card is equipped with an automatic configuration capability that reduces the installation process to a simple plug-and-play procedure. Simply connect the card to the line and it automatically configures itself for the maximum data rate supported by the local loop. The card can also be configured for fixed line speeds to achieve maximum distances.

The Hotwire 8799 TDM SHDSL Line Card offers these standard features:



AutoRate Capability. Provides automatic configuration of line speed and data rate upon connection.



Embedded Operations Channel (EOC). Provides remote management via SNMP or Telnet session capability over the DSL network. The bandwidth of the EOC is a 3 Kbps dedicated channel.



Asynchronous Terminal Interface (ATI). Provides a menu-driven VT100-compatible terminal interface for configuring and managing the unit locally or remotely by Telnet session.



Local Management. Provides local management using the Management Communications Card (MCC) with a:

— Terminal or PC via the Management Serial port of the DSLAM.

— Network Management System (NMS) via the Management MCC port of

the DSLAM through the line card’s 10BaseT port.



Remote Management. Provides remote management:

— Out-of-band, using an external modem through the Management Serial

port of the DSLAM.

— Inband using one of the DS0 channels as the management channel to

transport SNMP traffic to the MCC card.

— Using SNMP or Telnet through the 10BaseT port of the MCC or the

Internal Management Channel (IMC).



Alarm Indication. Activates front panel LEDs.



Diagnostics. Provides the capability to diagnose device and network problems and perform tests, including digital loopbacks, pattern tests, and self-test.



Device and Test Monitoring. Provides the capability of tracking and evaluating the card’s operation, including health and status, and error-rate monitoring. A full suite of loopback tests are supported, which can be initiated locally or remotely. Performance statistics are also provided.



Remote Send Line Loopback

The local device 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.

Send and Monitor 511 Pattern

The Send command is used to send a test pattern over the DSL interface. This test commands the remote unit to start sending and monitoring a 511 pattern, and then sends and monitors a 511 pattern. Ones are sent in the time slots that are mapped to the DSL port that is in test.

Pressing Enter after selecting the Send and Monitor 511 Pattern Start command from the DSL & G.703 Tests menu initiates the test. The result field initially displays hh:mm:ss - Out of Sync, where hh:mm:ss is the time that the test has been running. The error count displays Out of Sync until the unit has detected the 511 pattern.

Once the pattern is detected, the error count field is updated once every 10 seconds. It is displayed as a five-digit number with the maximum count being

99999.

The Send and Monitor 511 test is not a loopback test. Each unit independently sends and monitors a 511 pattern.

Acitivating a Send and Monitor 5111 test causes the EOC (used for management) to be lost to the remote unit.

Spectrum Management

Possible Settings: Enable, Disable Default Setting: Disable

For an STU-C, enabling spectrum management limits the DSL speeds on the unit to meet either ANSI T1.417 or BT Access Network Spectrum standards. The purpose of Spectrum Management is to facilitate a reasonable spectral environment for the coexistence of multiple technologies in a loop plant with an acceptable level of crosstalk between them. In some countries, the DSL service provider must meet the spectrum management specification of that country. For example, in the United Kingdom, it is a requirement that the product comply with the OFTel PSD mask for the loop length requested (short, medium or long). Support for this requirement is provided by enabling Spectrum Management and properly setting the Estimated Line Length option (see Tabl e A- 1 , D S L

Interface Options).



Spectrum Management appears only when DSL Mode is set to STU-C.

Enable – Spectrum Management is enabled.

System Clock

The Primary and Secondary System Clock References determine the clock used by ports in a cross-connect configuration. For System Clock configuration options, refer to Table A-7, System Clock Options. A Help screen is provided online for further information. To access the System Clock screen, follow this menu selection sequence:

Main Menu→Configuration→Current Configuration→System Clock

main/config/system_clock Slot: 18 Model: 8799

SYSTEM CLOCK

System Primary Clock Reference Internal System Secondary Clock Reference Internal

-------------------------------------------------------------------------------Ctrl-a to access these functions, ESC for previous menu MainMenu Exit Save Help

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 STU-C, the system clocks may be sourced from the 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 G.703 port which is being used in a cross-connection. The STU-C secondary clock sources are restricted to G.703 ports configured for Bypass mode. On an STU-C when system clock is configured for something other than internal, G.703 ports configured for Bypass mode and internal timing will use the user-specified clock as their reference. On an STU-R, the system clock may only be sourced from DSL ports being used in a cross-connection. If all ports on an STU-R are configured for Bypass mode, no configuration for system clock is required (primary and secondary clock should remain set to their default values).

A-16 April 2003 8799-A2-GB20-10

Page 91

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.

NOTES:

— If a G.703 port is configured for Signaling_CAS, time slot 16 is used for

signaling and is not available for cross-connection.

— Make sure that the number of DSL time slots defined are supported by the

DSL line rate. The maximum number of useful DSL time slots depends on the configuration (see Table A-2, Payload Rates and DSL Line Rates for

G.703). Useful DSL time slots are contiguous and start at Time Slot 1.
