Serial PCM Data Outputs.
In Unstructured CES mode, each pin carries a
1.544 Mbps or 2.048 Mbps serial stream.
In Structured CES mode, each pin carries a
1.544 Mbps or 2.048 Mbps serial stream which
contains a 24-channel data stream in DS1 operation or
a 32-channel data stream in E1 operation.
Serial PCM Signalling Outputs or Output Loss of Signal
(LOS) Indicators.
In Structured CES mode, these pins output CAS
signalling.
In Unstructured CES mode, each of these pins outputs
an LOS or general purpose signal based on a user-
programmable value in TDM Control Register 3 for the
corresponding port.
