2. These options are valid only if you have a CSU and the Line Code is ami . If you have
a CSU and the Line Code is b8zs , then this setting will default to n/a . If you have a
DSX module, then this setting will always default to n/a .
3. These options are valid only if you have a CSU. If you have a DSX module, then the
possible options are 0 (default), 133, 266, 399, 533, 655 , and csu .
4. The settings for AIS/ALM are affected by the setting of Group.
5. If the format is d4 or slc96, the only option to appear will be none .
6. If there is no redundant WAN card in the appropriate slot the only option that will
appear is n/a .
7. Selection of GROUP is a two-step process. After identifying the group number (1-4),
the user must select the secondary group (A, B, or C). At which point TCODR will then
become available.
STATE
In the standby state, the WAN port is electrically disconnected from the network. Set this field
to
stdby (standby) while configuring WAN links, and then change it to actv (active) when
starting normal operations. If the WAN is in loopback due to a command from a remote
device, the loopback will be dropped if you switch to
stdby .
MODE
In cross-connect systems, the Mode automatically defaults to ( xcon ).
FORMAT
The Format setting specifies the frame format to be used on the WAN link so that it matches
the frame format used by the T1 carrier. Set the Format parameter based on the type of frame
format the T1 carrier requires. If you are using an external Channel Service Unit (CSU), the
frame format must match that of the CSU. The options are
d4 (normal superframe), esf
(extended superframe), slc96 (subscriber loop carrier) and slcd4 (subscriber loop carrier - D4).
Table 7-3 lists the DS0 time slots and their corresponding SLC

assignments, based on
Bellcore TR-TSY-000008.
LINE CODE
The Line Code setting matches the Line Code used by the T1 interface to that used by the T1
network. Set the Line Code to the type of Line Code used. If you are connected to an external
CSU, the line code must match that of the CSU. The options are
ami and b8zs .
