.
Transport modes:
Framer
—
LIU: Transmit positive-rail or single-rail DS1/E1 line
data output (to an external LIU).
M12 or E12 or VT Mapper: Transmit DS1/E1/VC/DS2/E2 data
output.
M23 or E23: Transmit DS2/E2 data output. Up to 21 DS2/12
E2 signals may be assigned to any of the 30 LINETXDATA
outputs.

Configurable Inputs/Outputs from the Internal Cross
Connect and Can Be Individually 3-Stated.
Transport mode:
Framer
—
LIU: Transmit DS1/E1 line clock output.
M12 or E12 or VT mapper: Transmit DS1/E1/VC line clock
output. If, in M12/E12 mode, DS1/E1 signals don
’
t go out of
the device, these pins may carry DS2 clock input/output for
M12/E12 deMUX.
M23 or E23: Transmit DS2/E2 clock input/output. Up to
21 DS2/12 E2 signals may be assigned to any of the 30
LINETXCLK outputs.
