DSX-1 Signaling Assignments and Trunk Conditioning

Procedure
1. Follow this menu selection sequence:
Configuration Edit/Display
Assignments
2. The DSX-1 to Network Assignments screen appears. This screen contains a
matrix of the current cross-connect status of all time slots on the Network
interface.
3. If you are using the 9261 Dual T1 NAM, you must choose which Network
interface to use. Enter 1 or 2 in the NETWORK field.
4. Move the cursor to the next editable time slot (underlined). Use the spacebar
or type in the desired time slot to display the desired time slot assignment.
5. Repeat Step 3 until all desired time slots are assigned. Select Save to save
the assignments, or press ESC to save and return to the Cross Connect
menu.
The second page of the DSX-1 to Network 1/2 Assignments screen enables you
to define the signaling assignments and trunk conditioning for each time slot on
the DSX-1 interface. You can specify whether robbed bit signaling information is
being passed within a given DS0, and the value of the signaling bits that will be
transmitted for that DS0 to the other cross-connected T1 interface if a Carrier
Group Alarm (CGA) occurs on a T1 interface.
Only those DSX-1-to-Network assignments from page 1 are displayed on this
page, from left to right and top to bottom in ascending order, by network and time
slot.
When a CGA condition (LOS, OOF or AIS) is declared for a T1 interface, the
signaling bits being transmitted to the other T1 interface for the DS0 are forced to
idle for two seconds (except for user-defined patterns which are transmitted
immediately). This drops any call in progress. The signaling bits are then forced
to the selected state (Busy or Idle), and remain in this state until the CGA
condition clears. At this point, the received signaling bits from the T1 interface
which formerly had the CGA condition are passed through to the other T1
interface.
NOTE:
Trunk conditioning will only occur on DS0s that are cross-connected to
another T1 interface. All other DS0s remain unaffected by trunk conditioning.
Enter one of the values shown in
Network side and the DSX-1 side. Although you can choose any value for the
DSX-1 side, the default value displayed is based on a typical setting that would
be used with the corresponding Network side value. Typical pairs of values are
shown in the table below. If you change the setting of None to anything else, the
DSX side value is changed to the corresponding default value.
