Embedded Framers
The CX29503 contains DS3/E3, DS2/E2, and DS1/E1/J1 PDH framers. In this
document, DS1 refers to both DS1 and J1 formats unless specified. The J1 format is
enabled by setting the RINCF bit in the DS1/E1 Primary Control register (DS1/E1
Framer block, addr: 0x001).
See
Table 1-1. Number of Framer Blocks
The framers support full Performance Monitoring (PM) and network alarm detection
in the receive direction and network alarm insertion in the transmit direction.
Equivalent functionality is provided in the SONET/SDH domain at the VT1.5/VT2.0
and VC-11/VC-12 levels. At the STS-1/TUG-3 levels, the companion SONET/SDH
multiplexer device performs the network alarming and PM functions, although the
CX29503 performs a subset of this functionality.
Framing and SONET/SDH operation details are provided later in the data sheet.
