10.12 Trail Trace Controller
10.12.1 General Description
Each port has a dedicated Trail Trace Buffer for E3-G.832 or DS3/E3 PLCP link management
The Trail Trace Controller performs extraction and storage of the incoming G.832 or PLCP trail access point
identifier in a 16-byte receive register.
The Trail Trace Controller extracts/inserts E3-G.832 or PLCP trail access point identifiers using a 16-byte
register(one for transmit, one for receive). (E3-G.832 and PLCP Framing are mutually exclusive, therefore one
controller can be used for both.)
The Trail Trace Controller de-maps a 16-byte trail trace identifier from the E3-G.832 TR Byte of the overhead or
PLCP datastream in the receive direction and maps a trace identifier into the E3-G.832 or PLCP datastream in the
transmit direction.
The receive direction inputs the trace ID data stream, performs trace ID processing, and stores the trace identifier
data in the data storage using line timing. It removes trace identifier data from the data storage and outputs the
trace identifier data to the microprocessor via the microprocessor interface using register timing. The data is forced
to all ones during LOS, LOF and AIS detection to eliminate false messages
The transmit direction inputs the trace identifier data from the microprocessor via the microprocessor interface and
stores the trace identifier data in the data storage using register timing. It removes the trace identifier data from the
data storage, performs trace ID processing, and outputs the trace ID data stream. See
Figure 10-45

of the Trail Trace Controller with the DS316x devices.
