Function
Receive Signaling Data (RSIG), port 1
PC(1:4).RPC(3:0) = 0100
The received CAS signaling data is sourced by this pin. Time
slots on RSIG correlate directly to the time slot assignment
on RDO.
In 4:1 system interface multiplex mode four received signaing
data streams are merged into a single data stream
respectively which is transmitted on RPB1 (bit- or byte-
interleaved).
Data Link Bit Receive (DLR), port 1
PC(1:4).RPC(3:0) = 0101
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.
Freeze signaling (FREEZE), port 1
PC(1:4).RPC(3:0) = 0110
The freeze signaling status is set active high by detecting a
loss of signal alarm, a loss of CAS frame alignment or a
receive slip (positive or negative). It will stay high for at least
one complete multiframe after the alarm disappears. Setting
SIC2.FFS enforces a high on pin FREEZE.
Frame Synchronous Pulse (RFSP) , port 1
RFSP, PC(1:4).RPC(3:0) = 0111
Active low framing pulse derived from the received PCM
route signal (line side, RCLK). During loss of synchronization
(bit FRS0.LFA = 1
during alarm simulation).
Pulse frequency: 8 kHz
Pulse width: 488 ns (E1) or 648 ns (T1/J1).
Receive Line Termination (RLT), port 1
PC(1:4).RPC(3:0) = 1000
General Purpose Input (GPI), port 1
PC(1:4).RPC(3:0) = 1001
The pin is set to input. The state of this input is reflected in
the register bits MFPI.RPA, MFPI.RPB or MFPI.RPC
respectively.
General Purpose Output High (GPOH), port 1
PC(1:4).RPC(3:0) = 1010
The pin level is set fix to high level.
