Configuring an ADSL 72-Port
Line Interface Module (LIM)
The Stinger asymmetric digital subscriber line (ADSL) 72-port Annex A line interface
module (LIM) provides 72 ADSL interfaces that support high-speed asymmetric data
transfer using the ANSI discrete multitone (DMT), G.lite, and G.dmt ADSL protocols.
The ADSL 72-port Annex A LIM, product code STGR-LIM-AD-72, is supported by
both the Stinger FS+ and Stinger LS chassis.
Installing an ADSL 72-port Annex A LIM
Install the ADSL 72-port LIM in the same manner as other LIMs. See the Stinger
Getting Started Guide for your unit for details. After installation, the module must be
configured following the instructions in this guide.
Table 1-1 shows compatible LIM models, Stinger chassis and line protection modules:

Interpreting ADSL 72-port Annex A status lights
Several status lights on the front panel of the ADSL 72-port Annex A LIM indicate
the status of the module and its ports. Figure 1-1 shows the front panel and status
lights of the ADSL 72-port Annex A LIM.
Figure 1-1. ADSL 72-port Annex A LIM
All status lights illuminate briefly upon startup or restart, then remain dark until the
module passes its power-on self test (POST). When the module passes the POST and
becomes operational, the ACTIVE light illuminates.

Table 1-2 explains the ADSL 72-port Annex A status lights.
Configuring ATM ADSL-DMT interfaces
A Stinger unit creates an al-dmt profile for each ADSL-DMT interface in the system.
For example, for an ADSL-DMT LIM installed in slot 14, the system creates the
following profiles:
admin> dir al-dmt

Overview of the al-dmt profile
Various discrete multitone (DMT) standards define the fast and interleaved data
latencies for each direction (upstream and downstream) of ADSL transmission. In the
Stinger profiles, you set parameters to specify the data rate, signal quality and power,
and data delay of the interface. The Stinger unit references these parameters in the
training process.
Table 1-2. ADSL 72-port Annex A LIM status lights
Light Color Indication
STBY Orange The module is a designated spare. The control
module switches traffic to the module if one of
the other modules fails.
ACTIVE Green The module or port is fully operational and no
errors have been detected.
FAULT Orange The module failed to pass its POST.
BYPASS Orange The module is in bypass mode. (The module
redundancy feature is activated.)
PORT Green The local and remote ends of the physical line
have achieved frame synchronization, and the
local end of the ATM link has achieved cell
delineation.
If the light is not illuminated, the port is inactive.

Configuring an ADSL 72-Port Line Interface Module (LIM)
Configuring ATM ADSL-DMT interfaces
Stinger®ADSL 72-Port Annex A Line Interface Module (LIM) Guide 1-5
The following sets of parameters are active in the current software version:
■ Line activation and DMT parameters
■ Rate adaptive mode parameters
■ Power spectral density (PSD) and power-level parameters
■ Fast and interleaved bit-rate parameters
■ Interleaving delay parameters
■ Noise margin parameters
■ Dynamic rate adaptive parameters
■ Trellis encoding
■ Automatic Gain Control
The following AL-DMT features are not yet supported:
■ Dual latency
■ Dynamic rate adaptation
These features are not present in the current software version. However, the
parameters related to these features are present in the Al-Dmt profile.
ADSL protocol support
The ADSL 72-port Annex A LIM supports the following protocol standards:
■ ANSI DMT—ANSI T1.413.2
■ G.dmt—ITU 992.1
■ G.lite—ITU 992.2, ITU 994.1
By setting the line-code parameter in the line-config subprofile to auto-select,
the LIM automatically detects and configures itself with the correct ADSL protocol.
This is the optimum setting for the ADSL 72-port Annex A LIM.
No matter which protocol is used, in general, the al-dmt profile parameters remain
the same and are configured in the same way. Exceptions are the line-latency-down
and line-latency-up parameters. When the G.lite protocol is specified or detected,
these parameters are automatically set to the value interleave.
Line activation and DMT parameters
Each direction of traffic (upstream and downstream) on an ADSL-DMT line can have
a different minimum and maximum bit rate. The ADSL 72-port Annex A LIM does
not support dual latency, which can use both the fast and interleaved channels in
both directions.
The Al-Dmt profile
The Al-Dmt profile contains the following parameters and subprofiles, shown with
default values, for activating and setting up an AL-DMT line. These profile and
subprofile parameters are described in the following tables.

example, 1:2:3), but you can assign a text string of up to
16 characters.
physical-address Specifies the physical address of the interface in the

disabled until you activate the line in the al-dmt profile.
sparing-mode Enables or disables port redundancy (sparing) and
specifies the mode.
The default value, inactive, disables LIM port
redundancy (sparing).
The automatic setting activates automatic sparing for the
port. The values of the error threshold parameters
specified in the
auto-lim-sparing-config:lim-sparing-config [slot

The manual setting deactivates the LIM port and
reestablishes the connection onthe same port of the spare
LIM.
