DESCRIPTION
Receive DS1/E1 Clock Output - Channel 22:
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_22" line, upon the rising edge of this signal.
Power Supply Pin
Receive DS1/E1 Data Output - Channel 21
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_21.
Receive DS1/E1 Clock Output - Channel 21:
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_21" line, upon the rising edge of this signal.
Receive DS1/E1 Data Output - Channel 20:
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_20.
Receive DS1/E1 Clock Output - Channel 20:
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_20" line, upon the rising edge of this signal.
Receive DS1 Data Output - Channel 19:
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_19.
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 # 5, if M12
MUX # 5 is bypassed.
Receive DS1 Clock Output - Channel 19:
This pin outputs a DS1 (1.544MHz) clock signal to the Terminal
Equipment. The XRT72L13 will update the data on the
"RxDS1Data_19" line, upon the rising edge of this signal.
This output pin is inactive if the corresponding M12 DEMUX is de-
multiplexing an ITU-T G.747 data stream.
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
# 5 is bypassed.
Receive DS1/E1 Data Output - Channel 18
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_18.
