3. Configuration Options

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 Table 3-23, Signaling and Trunk Conditioning Values, in each of the fields on both the 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 Network side value, the DSX side value is changed to the corresponding default value.

Meanings

DSX-1 Side

 

 

 

None

No signaling used on this DS0. Use this setting if

None

 

there is no voice signaling information being passed

 

 

on this DS0 (clear channel).

 

 

 

 

RBS (default)

Robbed Bit Signaling is used on this DS0, but no

RBS

 

trunk conditioning. Signaling bits will be passed to the

 

 

T1 interface to which this DS0 is cross-connected

 

 

when this T1 interface is not in CGA, but the signaling

 

 

bits will be all ones when CGA is present.

 

 

 

 

The following values configure the cross-connect for RBS, as well as perform the trunk conditioning. Although ABCD signaling bits for each setting are described, only AB bits are transmitted when the cross-connected T1 network interface is using D4 framing.
