Line Transmit Clock (28:1). Configurable outputs from
the internal cross connect. Can be used as the clock
signals for LINETXDATA(28:1) in DS1, E1, and DS2
modes.
Line Transmit Clock 29. Configurable output to the
internal cross connect for the protection or timing refer-
ence channel. Also used as the transmit global system
clock input for CHI (2.048 MHz, 4.096 MHz, 8.192 MHz,
or 16.384 MHz), PSB (19.44 MHz), and NSMI (51.84
MHz) modes.
Line Transmit Synchronous (28:1). Configurable
inputs/outputs to the internal cross connect. An output
when used as the negative rail of a DS1 or E1 output
port operating in dual-rail mode. In CHI mode, these
pins may be used as output TDM highways. In PSB
mode, bits 16:1 are used for the transmit data bus, and
bits 28:17 are not used. These pins may also be used
as DS2 I/O to the M12 block as follows: 7:1—Tx data
out. 14:8—Tx clock in. 21:16—Rx data in. 28:22—Rx
clock in.
Line Transmit Synchronous 29. Configurable input/
output to the internal cross connect. An output when
used as the negative rail of a DS1 or E1 output port
operating in dual-rail mode. In CHI and PSB modes, it is
used as the transmit system frame synchronization
input. In NSMI mode, it is the transmit system frame
sync output.
NSMI Receive Enable. Receive data enable for NSMI
mode.
NMSI Transmit Enable. Transmit data enable for NSMI
mode.
