Transmit STS-1 Telecom Bus – Channel 1 – Input Data
Bus pin number 5:
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 5:
STS1TXA_D5_1:
This
“STS1TXA_D_1[4:0] function as the “STS-1 Transmit (Add)
Telecom Bus – Input Data Bus for Channel 1. The STS-1
Telecom Bus interface will sample and latch this pin upon the
falling edge of “STS1TXA_CK_1”.
