Transmit STS-1 Telecom Bus – Channel 2 – Input Data
Bus pin number 4:
The exact function of this 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 Transmit Telecom Bus – Input Data Bus pin number 4:
STS1TXA_D4_2:
This
“STS1TXA_D_2[3:0] function as the “STS-1 Transmit (Add)
Telecom Bus – Input Data Bus for Channel 2. The STS-1
Telecom Bus interface will sample and latch this pin upon the
falling edge of “STS1TXA_CK_2”.

– Input data pin 4)
TXDS3OHIND_2 (Transmit DS3 Overhead Indicator –
Channel 2)
Transmit STS-1 Telecom Bus – Channel 2 – Input Data
Bus pin number 5:
The exact function of this 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 Transmit Telecom Bus – Input Data Bus pin number 5:
STS1TXA_D5_2:
This
“STS1TXA_D_2[4:0] function as the “STS-1 Transmit (Add)
Telecom Bus – Input Data Bus for Channel 2. The STS-1
Telecom Bus interface will sample and latch this pin upon the
falling edge of “STS1TXA_CK_2”.
TXHDLCDAT_5_2 (Transmit HDLC block data – Channel 2
– Input data pin 5)
TXDS3FP_2 (Transmit DS3 Frame Pulse – Channel 2)
Transmit STS-1 Telecom Bus – Channel 2 – Input Data
Bus pin number 6:
The exact function of this 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 Transmit Telecom Bus – Input Data Bus pin number 6:
STS1TXA_D6_2:
This
“STS1TXA_D_2[5:0]” function as the “STS-1 Transmit (Add)
Telecom Bus – Input Data Bus for Channel 2. The STS-1
Telecom Bus interface will sample and latch this pin upon the
falling edge of “STS1TXA_CK_2”.
