Receive Signaling Marker (RSIGM)

PC(1:4).RPC(2:0) = 011

E1: Marks the time slots which are defined by

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 Sa(8:4)-bits within the data

stream on RDO. The Sa(8:4)-bit positions in

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.
