E1 Registers
RMFB: Receive Multiframe Begin (Output)
Marks the beginning of every received multiframe or optionally the begin of every CAS
multiframe begin (active high).
0010B
RSIGM: Receive Signaling Marker (Output)
Marks the time slots which are defined by register RTR(4:1) of every frame on port RDO.
0011B
RSIG: Receive Signaling Data (Output)
The received CAS multiframe is transmitted on this pin. Time slot on RSIG correlates directly
to the time slot assignment on RDO.
0100B
DLR: Data Link Bit Receive (Output)
Marks the Sa-bits within the data stream on RDO.
0101B
FREEZE: Freeze Signaling (Output)
The freeze signaling status is active high by detecting a loss-of-signal alarm, or a loss of CAS
frame alignment or a receive slip (positive or negative). It stays high for at least one complete
multiframe after the alarm disappears. Setting SIC2.FFS enforces a high on pin FREEZE.
0110B
RFSP: Receive Frame Synchronous Pulse (Output, low active)
RFSP marks the frame begin in the receivers synchronous state. This marker is active low
for 488 ns with a frequency of 8 kHz.
0111B
RLT: Receive line termination (input)
1000B
GPI: general purpose input
Value of this input is stored in register MFPI.
1001B
GPOH: General purpose output, high level
Pin is set fixed to high level
1010B
GPOL: General purpose output, low level
Pin is set fixed to low level
1011B
LOS: Loss of signal
Loss of signal indication output
1100B
RTDMT: Receive TDM tristate (input)
receive TDM i/f tristate (RDO, RSIG, SCLKR, RFM).
1101B
reserved
1110B
RCLK: RCLK output

XPC1 Constant Values
Name and Description
Value
SYPX: Synchronous Pulse Transmit (Input, low active)
Together with register XC(1:0) SYPX defines the frame begin on the transmit system
interface ports XDI and XSIG.
0000B
XMFS: Transmit Multiframe Synchronization (Input)
Together with register XC(1:0) XMFS defines the frame and multiframe begin on the transmit
system interface ports XDI and XSIG. Depending on PC5.CXMFS the signal on XMFS is
active high or low.
0001B
XSIG: Transmit Signaling Data (Input)
Input for transmit signaling data received from the signaling highway. Optionally sampling of
XSIG data is controlled by the active high XSIGM marker.
