Designation Function Values Configuration Guidelines
CGA
Selects the method used to
signal the CGA (link out-of-
service) state to the other
link. The main link timeslots
assigned to the sublink carry
the signaling.
NONE – When the FCD-E1 sublink is in the out-of-
service state, the main link timeslots assigned to the
sublink carry the OOS code. In addition, the
signaling bits A, B also assume the OOS state (see
OOS SIGNAL).
TRANS – Same as for NONE, but the signaling bits
A, B are not forced to the OOS state.
FULL –FCD-E1 does not change the state of the
main link timeslots, or the state of the signaling bits.
Default: NONE
The recommended signaling method depends on the
application.
The NONE mode is non-transparent and is often used
when the sublink carries voice channels, for example, in
PABX or voice multiplexer applications.
The FULL mode is fully transparent and is often used when
the sublink carries channelized or unchannelized data.
Use the TRANS mode for voice applications with channel
associated signaling (proprietary signaling) and for
channelized data applications. This is the transparent mode.
Note: This parameter is displayed only for FCD-E1 versions with a sublink.
MAP MODE
Determines the selection
method for the sublink
timeslots transferred to the
main link.
USER – Free user selection of timeslots.
SEQ – Sequential selection of timeslots from a
user-specified slot.
Default: USER
The selected sublink timeslots are allocated the same
timeslots in the main link frame.
Note: This parameter is displayed only for FCD-E1 versions with a sublink.
TS TYPE 1..31
(when USER is
selected in MAP
MODE)
TS TYPE
(when SEQ is selected
in MAP MODE)
Controls the timeslot
connection state and type.
NC – Timeslot not connected to the main link
DATA – Timeslot handled as a data timeslot
VOICE – Timeslot handled as a voice timeslot
Default: NC
In USER mode, the type can be individually selected for
each timeslot
In SEQ mode, the selected type applies to all the timeslots
in the bundle
START TS
Selects the starting timeslot
for the SEQ timeslot
selection mode
Any number in the range of 1 to 31, consistent with
the desired number of user timeslots and with the
data channel timeslot allocations.
Default: 1
Do not select timeslot 16 when the framing mode is
G732N.
NUM OF TS
Selects the total number of
timeslots transferred as a
bundle from the sublink to
the main link, when using
the SEQ mode
Any number in the range of 1 to 31, consistent with
the desired number of user timeslots and with the
data channel timeslot allocations
Default: 1
