Receive STS-1 Telecom Bus – Channel 2 – Output Data
Bus pin number 1:
The exact function of this output pin depends upon whether
the STS-1 Telecom Bus Interface, associated with Channel 2
is enabled or not.
If STS-1 Telecom Bus (Channel 2) has been enabled –
STS-1 Receive Telecom Bus – Output Data bus pin number 1:
STS1RXD_D1_2
This output
“STS1RXD_D0_2 function as the “STS-1 Receive (Drop)
Telecom Bus – Output Data Bus for Channel 2. The STS-1
Telecom Bus Interface will update the data via this output
upon the rising edge of “STS1RXD_CK_2.
