External Clock References
Positive HDB3 or NRZ Data Transmit outputs. Eight E1 data channel
outputs (channel<i>, i=<7..0>) at 2.048 Mbit/s, in either NRZ or HDB3
format.
Negative HDB3 Data Transmit outputs. Eight E1 data channel outputs
(channel<i>, i=<7..0>) at 2.048 Mbit/s when HDB3 coding is used.
Transmit clock outputs. The 2.048 MHz clock output of each of the eight
independent transmitters (TCLK<i>, i=<7..0>) is to be used with the
corresponding E1 data (TPOSD<i> and TNEGD<i>) signals when needed.
Demultiplexed NRZ data inputs. Eight E1 data channel inputs
(transmitters, channel<i>, i=<7..0>) at 2.048 Mbit/s received from the
demultiplexer.
Demultiplexed Clock inputs. Eight E1 clock inputs (transmitters; channel
<i>, i=<7..0>) at 2.048 MHz received from the demultiplexer. These clocks
can be gapped due to the SDH frame structure and the justification
process.
Demultiplexer Re-timing Clock. This is an external 2.048 MHz reference
clock input that can be used in each E1 transmitter to retime the E1 data
received from the demultiplexer (wander reduction if the E1 transmitter # i
is configured in retiming mode). This clock is also used as a blue clock in
each receiver to generate an AIS signal in case of RLOS.
