Receive STS-1 Telecom Bus – Channel 1 – Output Data
Bus pin number 4:
The exact function of this output pin depends upon whether
the STS-1 Telecom Bus Interface, associated with Channel 1
is enabled or not.
If STS-1 Telecom Bus (Channel 1) has been enabled –
STS-1 Receive Telecom Bus – Output Data bus pin number 4:
STS1RXD_D4_1
This output
“STS1RXD_D_1[3:0]” function as the “STS-1 Receive (Drop)
Telecom Bus – Output Data Bus for Channel 1. The STS-1
Telecom Bus Interface will update the data via this output
upon the rising edge of “STS1RXD_CK_1.
RXHDLCDAT_4_1 (Receive HDLC block data output –
Channel 1 – Output Data Bus pin 4)
RXOHIND_1 (Receive Overhead Indicator – Channel 1)
Receive STS-1 Telecom Bus – Channel 1 – 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 1
is enabled or not.
If STS-1 Telecom Bus (Channel 1) has been enabled –
STS-1 Receive Telecom Bus – Output Data bus pin number 5:
STS1RXD_D5_1
This output
“STS1RXD_D_1[4:0]” function as the “STS-1 Receive (Drop)
Telecom Bus – Output Data Bus for Channel 1. The STS-1
Telecom Bus Interface will update the data via this output
upon the rising edge of “STS1RXD_CK_1.
RXHDLCDAT_5_1 (Receive HDLC block data output –
Channel 1 – Output Data Bus pin 5)
RXDS3FP_1 (Receive DS3 frame pulse – Channel 1)
Receive STS-1 Telecom Bus – Channel 1 – 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 1
is enabled or not.
If STS-1 Telecom Bus (Channel 1) has been enabled –
STS-1 Receive Telecom Bus – Output Data bus pin number 6:
STS1RXD_D6_1
This
“STS1RXD_D_1[5:0]” function as the “STS-1 Receive (Drop)
Telecom Bus – Output Data Bus for Channel 1. The STS-1
Telecom Bus Interface will update the data via this output
upon the rising edge of “STS1RXD_CK_1.
