TYPE
Receive STS-1 Telecom Bus - Channel 2 - Output Data Bus pin num-
ber 4:
The function of this output pin depends upon whether or not the STS-1
Telecom Bus Interface, associated with Channel 2 is enabled.
If STS-1 Telecom Bus (Channel 2) has been enabled
- STS-1 Receive Telecom Bus - Output Data bus pin number 4:
STS1RXD_D4_2
This output pin along with STS1RXD_D_2[7:5] and STS1RXD_D_2[3:0]
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_4_2 (Receive HDLC block data output - Channel 2 -
Output Data Bus pin 4)
RXOHIND_2 (Receive Overhead Indicator - Channel 2)
Receive STS-1 Telecom Bus - Channel 2 - Output Data Bus pin num-
ber 5:
The function of this output pin depends upon whether or not the STS-1
Telecom Bus Interface, associated with Channel 2 is enabled.
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 pin along with STS1RXD_D_2[7:6] and 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)
RXDS3FP_2 (Receive DS3 frame pulse - Channel 2)
Receive STS-1 Telecom Bus - Channel 2 - 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 2 is enabled.
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 output pin along with STS1RXD_D7_2 and 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.
RXHDLCDAT_6_2 (Receive HDLC block data output - Channel 2 -
Output Data Bus pin 6)
RXDS3DATA_2 (Receive DS3 data - Channel 2)
