Designation Function Values Configuration Guidelines
CGA
Selects the method used to
signal the carrier group
alarm (CGA) state (link
out-of-service) to the other
equipment connected to the
remote end of the sublink.
NONE When the sublink is in
the out-of-service
state, the
corresponding main link
timeslots carry the OOS
code selected by the
user.
TRANS Same as for NONE, but
the signaling bits are
not forced to the OOS
state.
FULL The state of the
timeslots and the state
of the signaling bits is
not changed. This mode
is
Default: NONE
The selection depends on your
particular application:
• NONE is suitable for voice
applications.
• TRANS applications with
common channel signaling
(proprietary signaling) and for
channelized data applications
• FULL is a fully transparent
mode, and is often used when
the sublink carries channelized
or unchannelized data
OOS_SIG
When NONE is selected for
the CGA parameter, this
parameter determines the
state of the signaling bits
during out-of-service
periods
FORCED BUSY – The signaling bits
are forced to the busy state
during out-of-service periods.
FORCED IDLE – The signaling bits
are forced to the idle state
during out-of-service periods.
BUSY IDLE – The signaling bits
are forced to the busy state for
2.5 seconds, then switch to the
idle state until the
out-of-service condition
disappears.
IDLE BUSY – The signaling bits
are forced to the idle state for
2.5 seconds, then switch to the
busy state until the
out-of-service condition
disappears.
Default: FORCED IDLE
Select in accordance with the
method specified for use in your
network.
OOS_CODE
When NONE or TRANS has
been selected for CGA,
selects the code transmitted
during out-of-service
periods
The available selections are 00
to FF (hexa).
Default: 00
Select in accordance with the
code specified for use in your
network.
Sublink Timeslot Mapping Considerations
Each sub timeslot selected by the user is connected to the timeslot with the
same number of the main link.
The handling of the timeslot is configured by means of its type:
