Setting T3 Mux Clocking; Performing Diagnostics; Looping An Individual Ds-1 Channel; Looping The T3 Line - Lucent Technologies PortMaster 4 Configuration Manual

You can now use the following command to set the T3 Mux board to provide clocking
to the backplane:
Command 1> set mux backplane-clock enable|disable

Setting T3 Mux Clocking

You can set a T3 Mux board to either provide clocking to the T3 line or obtain clocking
from the T3 line.
You use the external keyword to specify that the T3 Mux board obtain clocking from
the T3 line. When you use the internal keyword, the T3 Mux board provides clocking
for the T3 line. To set T3 Mux clocking, you must first set the view to the slot with the
installed T3 Mux board. For a T3 Mux board installed in slot 1, for example, you enter
the following command:
Command 1> set view 1
You can now use the following command to set T3 Mux clocking:
Command 1> set mux line-clock external|internal

Performing Diagnostics

This section describes how to enable a PortMaster 4 to conduct loopback tests on a
single DS-1 channel and on a T3 line.

Looping an Individual DS-1 Channel

To use the following command to perform diagnostic loopback tests on a single DS-1
channel within a T3 line, you must first set the view to the slot with the installed T3
Mux board. For a T3 Mux board installed in slot 1, for example, enter the following
command:
Command> set view 1
You then enter the following command to enable the PortMaster to perform loopback
tests on a single DS-1 channel:
Command 1> set mux channel-loop Channel auto|on|off

Looping the T3 Line

To use the following command to diagnose a T3 line, you must first set the view to the
slot with the installed T3 Mux board. For a T3 Mux board installed in slot 1, for
example, enter the following command:
Command> set view 1
You can then use the following command as a diagnostic to loop the T3 line:
Command 1> set mux line-loop auto|on|off
