DESCRIPTION
Receive DS1/E1 Clock Output - Channel 18:
This pin outputs either a DS1 (1.544MHz) or an E1 (2.048MHz) clock
signal to the Terminal Equipment. The XRT72L13 will update the data
on the "RxDS1Data_18" line, upon the rising edge of this signal.
Receive DS1/E1 Data Output - Channel 17:
This pin outputs either a DS1 or E1 signal from the M12 multiplexer.
Each bit, within the DS1 or E1 data stream is output upon the rising
edge of RxDS1Clk_17.
Receive DS1/E1 Clock Output - Channel 17:
This pin outputs either a DS1 (1.544MHz) or an E1 (2.048MHz) clock
signal to the Terminal Equipment. The XRT72L13 will update the data
on the "RxDS1Data_17" line, upon the rising edge of this signal.
Receive DS1/E1 Data Output - Channel 16:
This pin outputs either a DS1 or E1 signal from the M12 multiplexer.
Each bit, within the DS1 or E1 data stream is output upon the rising
edge of RxDS1Clk_16.
Receive DS1/E1 Clock Output - Channel 16:
This pin outputs either a DS1 (1.544MHz) or an E1 (2.048MHz) clock
signal to the Terminal Equipment. The XRT72L13 will update the data
on the "RxDS1Data_16" line, upon the rising edge of this signal.
Receive DS1 Data Output - Channel 15:
This pin outputs a DS1 signal from the M12 multiplexer. Each bit,
within the DS1 data stream is output upon the rising edge of
RxDS1Clk_15.
NOTES:
1. This output pin is inactive if the corresponding M12 DEMUX is
de-multiplexing an ITU-T G.747 data stream.
2. This pin will output the contents of DS2 channel # 4, if M12
MUX # 4 is bypassed.

Receive DS1 Clock Output - Channel 15:
This pin outputs a DS1 (1.544MHz) clock signal to the Terminal
Equipment. The XRT72L13 will update the data on the
"RxDS1Data_15" line, upon the rising edge of this signal.
NOTES:
1. This output pin is inactive if the corresponding M12 DEMUX is
de-multiplexing an ITU-T G.747 data stream.
2. This pin will output a DS2 rate clock signal (6.312MHz) if M12
# 4 is bypassed.
