FF1 8# 4# 4# 1# 2# (0-24)# for Master Cabinet
FF1 8# 4# 5# 1# 2# (0-24)# for Slave Cabinet
Specify the number of T1 channels used when "Fractional
T1" is needed (using only a portion of the 24 available
channels on the T1 card).
0 = None (no T1 channels are used)
1 thru 24 = Number of T1 channels used
FF1 8# 4# 4# 1# 3# (0 or 1)# for Master Cabinet
FF1 8# 4# 5# 1# 3# (0 or 1)# for Slave Cabinet
Specify the framing format used by the T1.
Be sure to match the framing format ordered from the CO.
In most cases, SF (SuperFrame; also known as D4) is used.
SF consists of 12 frames, with each frame including 192
information bits.
ESF (Extended SuperFrame) can also be selected. ESF
consists of 24 frames, and supports monitoring and mainte-
nance capabilities not available in the SF format.
For changes to this parameter to take effect, the system
must be powered down, then powered back up.
0 = SF (D4)
1 = ESF
FF1 8# 4# 4# 1# 4# (0 or 1)# for Master Cabinet
FF1 8# 4# 5# 1# 4# (0 or 1)# for Slave Cabinet
Specify the clear channel format used by the T1 for line
coding.
Be sure to match the clear channel format ordered from the
CO. In most cases, AMI (Alternate Mark Inversion) is
used. B8ZS (Binary 8-Zeros Suppression) can also be
selected.
For changes to this parameter to take effect, the system
must be powered down, then powered back up.
0 = AMI
1 = B8ZS
