PM5343 STXC
SONET/SDH TRANSPORT OVERHEAD TRANSCEIVER
4 APPLICATION EXAMPLE
The STXC is typically used to implement a portion of an STS-3/STM-1 line
Interface. The STXC may find application in many different types of SONET/SDH
network elements including switches, terminal multiplexers, and add-drop
multiplexers. In such applications, the STXC typically interfaces on its line side
with a clock and data recovery device (for the receiver) and a physical media
device such as a laser (for the transmitter). The system side interfaces directly to
the PM5344 SONET/SDH Path Terminating Transceiver (SPTX) where pointer
processing and path overhead termination are performed for an STS-3/STM-1
stream. The initial configuration and ongoing control and monitoring of the STXC
are normally provided via a generic microprocessor interface.
