Select Additional Optical Pin Functions
Together with bit LIM3.ESY the functionality of pin 80 is defined:
Programming of LOOP.SPN and LIM3.ESY and the corresponding
pin function is shown below.

H
Only bipolar violations are detected.
Bipolar violations and zero strings of 8 or more contiguous
zeros in B8ZS code or more than 15 contiguous zeros in AMI
code are detected additionally and counted in the code violation
counter CVC.
00… function of pin 80 XSIG: If SIC3.TTRF = 1, transmit data
from the system interface. Internal multiplexing with the XDI
data stream is controlled by XSIGM. No input function defined
for SIC3.TTRF = 0.
01… function of pin 80 SYNC2: external synchronization input
for the DCO-X circuitry
10… function of pin 80 ROID: Receive Optical Interface Data
(Input) and Pin 68: XMFB/XOID Transmit Optical Interface Data
(Output). At the same time data received on pin 2 are ignored,
data on pin XOID (pin 15) are undefined. Transmit data is
clocked off with the positive transition of XCLK. After Reset the
transmit multiframe begin marker is output on pin 68.
11… function of pin 80 XSIG: The signaling information from
the transmit system interface is received on pin XSIG. Bit
FMR5.EIBR should be cleared to disable internal signaling
access from registers XS1...12. The signaling information from
the line interface is transmitted on pin RSIG.
