Bits 4 to 0: Receive Channel Monitor Bits (RCM[4:0]). RCM0 is the LSB of a 5-bit channel select that
determines which receive DS0 channel data will appear in the RDS0M register.

Default
Bit 4 (T1 Mode): Receive Force Signaling All Ones (RFSA1)
Bit 4 (E1 Mode): CAS Mode Select (CASMS)
Bit 2: Receive-Signaling Force Freeze (RSFF). Freezes receive-side signaling at RSIGn (and RSERn if receive-
signaling reinsertion is enabled); will override receive freeze enable (RFE).
Bit 1: Receive-Signaling Freeze Enable (RSFE)
Bit 0: Receive-Signaling Integration Enable (RSIE)
19-5856; Rev 4; 5/11
0 = Do not force robbed bit signaling to all ones.
1 = Force signaling bits to all ones on a per-channel basis according to the T1RSAOI1–3 registers.
0 = The DS26514 will initiate a resync when two consecutive multiframe alignment signals have been
received with an error.
1 = The DS26514 will initiate a resync when two consecutive multiframe alignment signals have been
received with an error, or 1 multiframe has been received with all the bits in time slot 16 in state 0.
Alignment criteria is met when at least one bit in state 1 is present in the time slot 16 preceding the
multiframe alignment signal first detected (G.732 alternate criteria).
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 RSIGn (and RSERn if receive-signaling reinsertion is
enabled).
0 = Signaling changes of state reported on any change in selected channels.
1 = Signaling must be stable for three multiframes in order for a change of state to be reported.
