Transmit Time Slot Octet Identifier Output 3 (TxCHNn_3) / Trans-
mit Overhead Synchronization Pulse (TxOHSYNCn):
The exact function of these pins depends on whether or not the trans-
mit 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 processed by the trans-
mit 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 processed by the trans-
mit 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.
