Transmit Time Slot Octet Identifier Output 3 (TxCHNn_3) /
Transmit Overhead Synchronization Pulse (TxOHSYNCn):
The exact function of these pins depends on whether or not
the transmit framer enables the transmit fractional/signaling
interface, as described below:
If transmit fractional/signaling interface is disabled -
TxCHNn_3
These output signals (TxCHNn_4 through TxCHNn_0) reflect
the five-bit binary value of the current time slot being pro-
cessed by the transmit serial interface. Terminal Equipment
can use the TxCHCLK to sample the five output pins of each
channel in order to identify the time slot being processed. This
pin indicates Bit 3 of the time slot channel being processed.
If transmit fractional/signaling interface is enabled -
TxOHSYNCn
These pins are used to output an Overhead Synchronization
Pulse which indicates the first bit of each multi-frame.

:
Transmit fractional interface can be enabled by
programming to bit 4 - TxFr1544/TxFr2048 bit from
register 0xn120 to ‘1’.

Transmit Time Slot Octet Identifier Output-Bit 4
(TxCHNn_4):
These output signals (TxCHNn_4 through TxCHNn_0) reflect
the five-bit binary value of the current time slot being pro-
cessed by the transmit serial interface. Terminal Equipment
can use the TxCHCLK to sample the five output pins of each
channel in order to identify the time slot being processed. This
pin indicates the Most Significant Bit (MSB) of the time slot
channel being processed.
