Overhead Data Communication Channel
Mapped to Logical Channels (LCs)
SONET Overhead Communication Channels
If four CX29503 devices are connected to the SI-Buses which are processing SONET
signals, at least one of the four devices will pass the following overhead data
communication channels across the Overhead TSB: DCCR, DCCM, F2, F3, and Z5
(N1).
If the SONET payload includes DS3 signals, then the DS3 TDL communications
channel will be carried on the overhead TSB. If that DS3 signal contains DS1 or E1
signals, then 28 DS1 FDL channels or 21 E1 Sa channels will also be carried on the
overhead TSB.
