WAN Card User Screens and Settings WAN Card
The headers of all WAN card screens show the types of modules installed on those cards. The
above example shows a WAN DUAL card with a CSU module on port 1 and a DSX/CEPT
module configured for T1 DSX operation on port 2. This card is installed in WAN card slot
W1 of the system. Its screen header designation is therefore
W1 CSU+DSX
.
The DSX/CEPT and HDSL modules also have identical parameters. These are described in
the next section of this chapter.
Table 6-2 lists several actions you can perform from the WAN Card Main Screen. These
actions appear in the bottom-highlighted line of the screen. To perform an action, simply press
the key corresponding to the capital letter of the desired action. For example, to save your
parameter settings, press “
s”
to invoke the
Save
commands.
Table 6-2. Main Screen Actions
Table 6-3 lists the CSU/DSX settings on the screen, along with their possible and default
values. For information about cross-connects and for the DS0 time slot map used to connect
your WAN to voice and data user cards.
In addition to the Local and Line Loopbacks described below, a single or dual WAN card with
a CSU Module will recognize and respond to industry-standard T1 loop-up and loop-down
codes generated and applied from the network or a remote device. However, the WAN card
will ignore those codes if it has a DSX/CEPT Module.
