FF2 (1-64)# 21# (0-4)#
Specify which trunk channels are used for T1.
When assigning trunks as circuit type "3" (T1), start from
the highest-numbered trunk port in the DBS cabinet struc-
ture, and move down sequentially from there.
If Fractional T1 is used, make sure that the number of
trunks assigned to circuit type "3" (T1) matches the "Num-
ber of T1 Channels" setting (see STEP 5 above). Also, if
your CPC-B version is 5.0 to 6.02, make sure the remaining
trunk ports on the TRK card are opened for analog usage in
the "T1 Trunk Closure" address (see FF1 8# 7# in this DBS
Manual).
For changes to this parameter to take effect, the system
must be powered down, then powered back up.
0 = Loop Start
1 = Ground Start
2 = Analog DID
3 = T1
4 = Caller ID (loop start)
Version 6.1 or higher)
FF1 8# 4# 6# (1-64)# 1# (0-3)#
Specify the type of trunk signaling that each T1 channel
emulates.
Be sure to match the signaling ordered from the CO. If
your system uses T1 COP Version 1.1 or 1.2 and you wish
to use the "Ground Start" setting, it must be upgraded to
Version 1.4 or higher.
For changes to this parameter to take effect, the system
must be powered down, then powered back up.
0 = Loop Start emulation
1 = (reserved for future use)
2 = Ground Start emulation
3 = E&M
