ADSL Protocol support

Introduction

Legacy Stinger ADSL Annex A LIMs, designed before the standardization and

implementation of ADSL2+ standards, do not have the capability to support ADSL2+.

LIMs that have been designed since that time support ADSL2+ features, depending on the

version of TAOS software that is installed.

Legacy ADSL Annex A protocols

All Stinger asymmetric digital subscriber line (ADSL) line interface modules (LIMs)

provide high-speed asymmetric data interfaces that support data transfer using the ANSI

discrete multitone (DMT) and the following protocols:

• ANSI T1.413

• ITU-T G.992.1 Annex A (G.dmt)

• ITU-T G.992.2 (G.lite)

ADSL2+ protocols

In addition to the legacy protocols, LIMs with ADSL2+ capability also support the ADSL

protocols and related standards shown below.

Important! When testing higher data transfer rates on ADSL2+ lines, network

equipment, test gear, and all links on the end-user or network must be able to support

10/100Mbps rates. ADSL2+ rates can not be properly tested on a network that does

not support 10/100Mbps Ethernet.

ADSL protocols and related standards Initial support

G.992.3 Annex A (G.dmt.bis) TAOS 9.6.0

G.992.4 Annex A (G.lite.bis) TAOS 9.6.0

G.992.5 Annex A (G.adsl2plus) TAOS 9.6.0

TAOS 9.6.1 is required for ADSL2+ support on

the Stinger Compact Remote.

G.992.3 Annex L (READSL2) TAOS 9.7.0

Single-ended loop testing (SELT) TAOS 9.7.2

Dual-ended loop testing (DELT) TAOS 9.7.2

ADSL LIM types

Introduction

As ADSL standards and hardware capabilities have changed, four types of Stinger ADSL

LIMs, in two broad categories, have been produced. LIM faceplates have changed and

some LIMs now have integrated line protection.

Legacy ADSL LIMs

Legacy ADSL LIMs were the first family of ADSL LIMs produced. They support the

legacy ADSL Annex A standards listed previously, and a maximum line rate of

18,016Kbps, but do not support ADSL2+ protocols.

LIMs with ADSL2+ capability

There are three groups of LIMs with ADSL2+ capability.

• Standard ADSL Annex A LIMs with ADSL2+ capability

These cards support all of the protocols listed previously.

• Enhanced processor LIMs with ADSL2+ capability

These cards support all of the protocols listed previously, but use newer processor and

components that allow additional IP features and the addition of integrated line

protection on one model.

• High bandwidth LIMs with ADSL2+ capability

These cards support all of the protocols listed previously, but support a maximum line

rate of 24,544Kbps and a total aggregate bandwidth per-card of 622Mbps. These LIMs

also contain enhanced processor components.

Integrated line protection

The use of enhanced processor components allow for the production of LIMs with

integrated line protection hardware. The resulting LIM/LPM card does not require a

separate, associated line protection module (LPM).

LIM faceplates

Legacy ADSL Annex A LIMs, and early LIMs with ADSL2+ capability have faceplates

with LEDs to indicate the status of individual ports. These LEDs are not present on LIMs

that use enhanced processor components. LIMs with integrated line protection hardware

have connectors for the line facilities located on the LIM faceplate.

These faceplates are illustrated in Figure 1-1.

ADSL LIM products and capabilities

Introduction

You cannot fully utilize the capabilities of an ADSL or ADSL2+ LIM unless it is installed

in a chassis that supports it, and the proper version of the TAOS software is installed on

that chassis.

Stinger FS chassis port limit

The backplane in the original Stinger FS chassis only supports the first 48 ports of any

LIMs installed in that chassis. Although 72-port LIMs can be installed in this chassis, only

the first 48 ports on the LIM can be utilized. All Stinger FS+, Stinger LS, Stinger RT, and

Stinger MS chassis provide full support for 72-port LIMs.

Installing an ADSL or ADSL2+ LIM

Purpose

This procedure describes how you install a LIM in a Stinger unit.

ESD Grounding

All Stinger chassis have at least one ESD grounding jack. Before installing or removing a

LIM, put on an antistatic wrist strap and plug it into an ESD grounding jack on the unit.

Ejector locks

Legacy LIMs have ejector locks that must be engaged during installation. (See

Figure 1-1 on page 1- 4.) Otherwise, physical installation is the same for all LIM models.

Installing a LIM

Prepare for installation by removing the blank slot cover or old LIM from the desired slot

on the unit. Use the following procedure to install the LIM.

........................................................................................................................................................................................................................

1 Align the LIM with the card guides and carefully slide the module into the unit.

WARNING

...........................................................................................................................................................................

Keep the connector on the LIM being inserted away from

components on adjacent LIMs.

Do not force the card.

................................................................................................................................

........................................................................................

2 Once the card has engaged its bus connector, press firmly to be sure it is fully seated.

Depress both ejectors simultaneously.

................................................................................................................................

........................................................................................

3 If the LIM is equipped with an ejector lock, slide the ejector lock up.

................................................................................................................................

........................................................................................

4 Using a number 2 Phillips screwdriver, secure the LIM by tightening the thumbscrews.

........................................................................................................................................................

E ND OF STEPS

Verifying operational status

Once the LIM is installed. Allow three to five minutes for it to become operational. Then

observe the behavior of the status lights on the LIM to verify its operational status.
