Configurable Inputs to the Internal Cross Connect.
Transport Modes:
Framer—LIU: Received positive-rail or single-rail DS1/E1
line data input (sourced from an external LIU).
M12 or E12: Normally used as receive DS1/E1 data input. If
DS1/E1’s come from internal source, these pins may also be
used as DS2/E2 inputs.
VT Mapper: Receive DS1/E1/VC data input.
M23 or E23: Receive DS2/E2 data input. Up to 21 DS2/12
E2 signals may be assigned to any of the 30 LINERXDATA
inputs.
Configurable Inputs to the Internal Cross Connect.
Transport Modes:
Framer—LIU: Receive DS1/E1 line clock input
M12 or E12: Normally used as receive DS1/E1 line clock
input (unless for demand clocking mode in which they are
used as clock outputs). If DS1/E1 signals come from internal
source, these pins may carry DS2/E2 clk input.
VT Mapper: Receive DS1/E1/VC line clock input
M23 or E23: Receive DS2/E2 clock input/output. Up to
21 DS2/12 E2 signals may be assigned to any of the 30 LIN-
ERXCLK inputs.
