Bit #
Name
Default
Bit 0/Force Receive Signaling All Ones (FRSAO). In T1 mode, this bit forces all signaling data at the RSIG and RSER pin to
all ones. This bit has no effect in E1 mode.
Bit 1/Transmit Time Slot Control for CAS Signaling (TCCS). Controls the order that signaling is transmitted from the
transmit signaling registers. This bit should be set = 0 in T1 mode.
Bit 2/Receive Time Slot Control for CAS Signaling (RCCS). Controls the order that signaling is placed into the receive
signaling registers. This bit should be set = 0 in T1 mode.
Bit 3/Receive Force Freeze (RFF). Freezes receive-side signaling at RSIG (and RSER if receive signaling reinsertion is
enabled); will override receive-freeze enable (RFE). See the Receive Signaling Freeze section.
Bit 4/Receive Freeze Enable (RFE). See the Receive Signaling Freeze section.
Bit 5/Unused, must be set to zero for proper operation.
Bit 6/Unused, must be set to zero for proper operation.
Bit 7/Global Receive Signaling Reinsertion Enable (GRSRE). This bit allows the user to reinsert all signaling channels
without programming all channels through the per-channel function.
0 = normal signaling data at RSIG and RSER
1 = force signaling data at RSIG and RSER to all ones
0 = signaling data is CAS format
1 = signaling data is CCS format
0 = signaling data is CAS format
1 = signaling data is CCS format
0 = do not force a freeze event
1 = force a freeze event
0 = no freezing of receive signaling data will occur
1 = allow freezing of receive signaling data at RSIG (and RSER if receive signaling reinsertion is enabled).
0 = do not reinsert all signaling
1 = reinsert all signaling
