AD1

TTL
Receive STS-3/STM-1 Telecom Bus Interface - C1/J1 Byte Phase
Indicator Input Signal:
This input pin should be pulsed "High" during both of the following condi-
tions.
a. Coincident to whenever the C1/J0 byte (within the incoming STS-
3/STM-1 signal) is being applied to the Receive STS-3/STM-1
Telecom Bus - Data Input pins (RXD_D[7:0]).
b. Coincident to whenever the J1 byte(s) (within the incoming STS-3/
STM-1 signal) is being applied to the Receive STS-3/STM-1
Telecom Bus - Data Input pins (RXD_D[7:0]) input.
N
OTE
:
This input pin should be pulled "Low" during all other times.

TTL
Receive STS-3/STM-1 Telecom Bus Interface - Parity Input pin:
This input pin can be configured to function as one of the following.
The EVEN or ODD parity value of the bits (within the incoming STS-3/
STM-1 signal) which are currently being input via the RXD_D[7:0] input
pins.
The EVEN or ODD parity value of the bits (within the incoming STS-3/
STM-1 signal) which are being input via the RXD_D[7:0] input and the
states of the RXD_PL and RXD_C1J1 input pins.
The Receive STS-3/STM-1 Telecom Bus Interface block will use this
input signal to compute and verify the Parity of each byte within the
incoming STS-3/STM-1 data-stream.
N
OTES
:
1.
Any one of these configuration selections can be made by
writing the appropriate value into the Telecom Bus Control
register (Address Location = 0x0137).
2.
Tie this input pin to GND if the STS-3/STM-1 Telecom Bus
Interface is disabled.
W1
RxD_ALARM
I
TTL
Receive STS-3/STM-1 Telecom Bus Interface - Alarm Indicator
Input:
This input pin should be pulsed "High" for one RxD_CLK period coinci-
dent to whenever the Receive STS-3/STM-1 Telecom Bus Interface is
accepting a byte from an incoming STS-1 or STS-3c signal (via the
RxD_D[7:0] input pins) that is carrying the AIS-P indicator.
This input pin should be held at a logic "Low" at all other times.
N
OTES
:
1.
If the RxD_ALARM input signal pulses "High" for any given
STS-1 signal (within the incoming STS-3), the XRT94L31 will
automatically declare the AIS-P defect condition for that STS-1
or STS-3c channel.
2.
Tie this input pin to GND, if the STS-3/STM-1 Telecom Bus
Interface is disabled.
