Function
Receive Signaling Marker (RSIGM)
PC(1:4).RPC(2:0) = 011
E1: Marks the time slots which are defined by
register RTR(4:1) of every received frame on
port RDO.
T1/J1: Marks the time slots which are defined
by register RTR(4:1) of every received frame
on port RDO, if CAS-BR is not used.
When using the CAS-BR signaling scheme,
the robbed bit of each channel every sixth
frames is marked, if CAS-BR is enabled by
XC0.BRM = 1.
Receive Signaling Data (RSIG)
PC(1:4).RPC(2:0) = 100
The received CAS signaling data is sourced by
this pin. Time slots on RSIG correlate directly
to the time slot assignment on RDO.
Data Link Bit Receive (DLR)
PC(1:4).RPC(2:0) = 101
E1: Marks the S
stream on RDO. The S
time slot 0 of every frame not containing the
frame alignment signal are selected by register
XC0.
T1/J1: Marks the DL-bit position within the data
stream on RDO .
