DESCRIPTION
Receive DS1/E1 Data Output - Channel 26:
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_26.
Receive DS1/E1 Clock Output - Channel 26:
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_26" line, upon the rising edge of this signal.
Receive DS1/E1 Data Output - Channel 25:
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_25.
Receive DS1/E1 Clock Output - Channel 25:
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_25" line, upon the rising edge of this signal.
Receive DS1/E1 Data Output - Channel 24:
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_24.
Receive DS1/E1 Clock Output - Channel 24:
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_24" line, upon the rising edge of this signal.
Receive DS1 Data Output - Channel 23:
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_23.
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 # 6, if M12
MUX # 6 is bypassed.
Receive DS1/E1 Clock Output - Channel 23:
This pin outputs a DS1 (1.544MHz) clock signal to the Terminal
Equipment. The XRT72L13 will update the data on the
"RxDS1Data_23" 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
# 6 is bypassed.
Receive DS1/E1 Data Output - Channel 22:
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_22.
