TYPE
Receive STS-1 Telecom Bus - Channel 0 - 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 0 is enabled.
If STS-1 Telecom Bus (Channel 0) has been enabled
- STS-1 Receive Telecom Bus - Output Data bus pin number 2:
STS1RXD_D2_0
This output pin along with STS1RxD_D_0[7:3] and STS1RxD_D_0[1:0]
function as the STS-3/STM-1 Receive (Drop) Telecom Bus - Output Data
Bus for Channel 0. The STS-3/STM-1 Telecom Bus Interface will update
the data via this output upon the rising edge of STS1RxD_CK_0.
RXHDLCDAT_2_0 (Receive HDLC block data output - Channel 0 -
Output Data Bus pin 2)
RXCELLRXED_0 (Receive cell received indicator - Channel 0)
Receive STS-1 Telecom Bus - Channel 0 - 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 0 is enabled.
If STS-1 Telecom Bus (Channel 0) has been enabled
- STS-1 Receive Telecom Bus - Output Data bus pin number 3:
STS1RXD_D3_0
This output pin along with STS1RXD_D_0[7:4] and STS1RXD_D_0[2:0]
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_3_0 (Receive HDLC block data output - Channel 0 -
Output Data Bus pin 3)
SSE_CLK (Slow Speed Clock Interface for Egress Path)
Receive STS-1 Telecom Bus - Channel 0 - 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 0 is enabled.
If STS-1 Telecom Bus (Channel 0) has been enabled
- STS-1 Receive Telecom Bus - Output Data bus pin number 4:
STS1RXD_D4_0
This output pin along with STS1RXD_D_0[7:5] and STS1RXD_D_0[3:0]
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_4_0 (Receive HDLC block data output - Channel 0 -
Output Data Bus pin 4)
RXOHIND_0 (Receive Overhead Indicator - Channel 0)
