Transmit STS-1 Telecom Bus – Channel 1 – Input Data
Bus pin number 1:
The exact function of this pin depends upon whether the STS-
1 Telecom Bus Interface, associated with Channel 1 is
enabled or not.
If STS-1 Telecom Bus (Channel 1) has been enabled –
STS-1 Transmit Telecom Bus – Input Data Bus pin number 1:
