TYPE
Receive STS-1 Telecom Bus - Channel 0 - Output Data Bus pin number
5:
The function of this output pin depends upon whether or not the STS-1
Telecom Bus Interface, associated with Channel 0 is enabled.
If STS-1 Telecom Bus (Channel 0) has been enabled
STS1RXD_D5_0
This output pin along with STS1RXD_D_0[7:6] and STS1RXD_D_0[4:0]
function as the STS-1 Receive (Drop) Telecom Bus - Output Data Bus
for Channel 0. The STS-1 Telecom Bus Interface will update the data via
this output upon the rising edge of STS1RXD_CK_0.

RXDS3FP_0 (Receive DS3 frame pulse - Channel 0)
Receive STS-1 Telecom Bus - Channel 0 - Output Data Bus pin num-
ber 6:
The function of this output pin depends upon whether or not the STS-1
Telecom Bus Interface, associated with Channel 0 is enabled.
If STS-1 Telecom Bus (Channel 0) has been enabled
- STS-1 Receive Telecom Bus - Output Data bus pin number 6:
STS1RXD_D6_0
This output pin along with STS1RXD_D7_0 and STS1RXD_D_0[5:0]
function as the STS-1 Receive (Drop) Telecom Bus - Output Data Bus
for Channel 0. The STS-1 Telecom Bus Interface will update the data via
this output upon the rising edge of STS1RXD_CK_0.
RXHDLCDAT_6_0 (Receive HDLC block data output - Channel 0 -
Output Data Bus pin 6)
RXDS3DATA_0 (Receive DS3 data - Channel 0)
Receive STS-1 Telecom Bus - Channel 0 - Output Data Bus pin num-
ber 7:
The function of this output pin depends upon whether or not the STS-1
Telecom Bus Interface, associated with Channel 0 is enabled.
If STS-1 Telecom Bus (Channel 0) has been enabled
- STS-1 Receive Telecom Bus - Output Data bus pin number 7:
STS1RXD_D7_0
This output pin along with STS1RXD_D_0[6:0] function as the STS-1
Receive (Drop) Telecom Bus - Output Data Bus for Channel 0. The
STS-1 Telecom Bus Interface will update the data via this output upon
the rising edge of STS1RXD_CK_0:.
