Table D-2. Link Configuration Parameters (Cont.)
Designation Function Values Configuration Guidelines OOS SIGNAL
When the CGA NONE mode is selected, this parameter determines the state of the A, B signaling bits sent to the main link during the periods the sublink is out-of-service. The signaling bits C and D are not affected (C is always “0”, and D is always “1”). Not displayed for G732N multiframes
SPACE – Both A and B signaling bits are forced to “1” during out-of-service periods. MARK – Both A and B signaling bits are forced to “0” during out-of-service periods. SP_MK – The A and B signaling bits are forced to “1” for 2.5 seconds, then switch to the “0” state until the out-of-service condition disappears. MK_SP – The A and B signaling bits are forced to “0” for 2.5 seconds, then switch to the “1” state until the out-of-service condition disappears. Default: SPACE
When NONE is used for CGA, select the OOS signaling mode used by the equipment connected to the corresponding link (relevant for sublink only).
Note: “1” – on-hook (idle) state “0” – off-hook (busy) state. This parameter is displayed only for FCD-E1 versions with a sublink.
OOS CODE
When either the CGA NONE or TRANS mode is selected, determines the code transmitted during out-of-service periods in the timeslots transferred between the sublink and the main link.
The available selections are 00 through FF (hexa) Default: FF
When NONE or TRANS is used for CGA, select the out-of-service code recommended for use in your network (relevant for sublink only).
Note: This parameter is displayed only for FCD-E1 versions with a sublink.
