Receive STS-1 Telecom Bus – Channel 2 – Output Data
Bus pin number 5:
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 5:
STS1RXD_D5_2
This output
“STS1RXD_D_2[4:0]” 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.
RXHDLCDAT_5_2 (Receive HDLC block data output –
Channel 2 – Output Data Bus pin5):
This output pin along with RxHDLCDat_
RXDS3FP_2 (Receive DS3 frame pulse – Channel 2)
Receive STS-1 Telecom Bus – Channel 2 – Output Data
Bus pin number 6:
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 6:
STS1RXD_D6_2
This
“STS1RXD_D_2[5:0]” 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.
