OC-12/STM-4 Path Termination for HDLC Application
The CX29503 is targeted for a network edge application where SONET/SDH or PDH
traffic is terminated for HDLC payload processing. The CX29503 is targeted for
interfacing to Mindspeed’s OC-12/OC-3 SONET/SDH multiplexer on the line side
and Mindspeed’s 1,024-Channel HDLC controller (CX28500) on the system side.
Typical applications of the CX29503 in SONET/SDH and PDH applications are
illustrated in
In the OC-12/STM-4 application, four CX29503s are used along with a single OC-12
SONET/SDH multiplexer device and two 1,024-Channel HDLC controllers. This
application allows for a termination of tributary signals down to DS1/E1.
