TYPE
Receive STS-1 Telecom Bus - Channel 2 - Output Data Bus pin num-
ber 1:
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 1:
STS1RXD_D1_2
This output pin along with STS1RXD_D_2[7:2] and 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.
RXHDLCDAT_1_2 (Receive HDLC block data output - Channel 2 -
Output Data Bus pin 1)
RXGFC_2 (Receive GFC output data - Channel 2)
Receive STS-1 Telecom Bus - Channel 2 - Output Data Bus pin num-
ber 2:
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 2:
STS1RXD_D2_2
This output pin along with STS1RXD_D_2[7:3] and STS1RXD_D_2[1:0]
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_2_2 (Receive HDLC block data output - Channel 2 -
Output Data Bus pin 2)
RXCELLRXED_2 (Receive cell received indicator - Channel 2)
Receive STS-1 Telecom Bus - Channel 2 - Output Data Bus pin num-
ber 3:
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 3:
STS1RXD_D3_2
This output pin along with STS1RXD_D_2[7:4] and STS1RXD_D_2[2:0]
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_3_2 (Receive HDLC block data output - Channel 2 -
Output Data Bus pin 3)
