GENERAL DESCRIPTION
The DS3146/DS3148/DS31412 (DS314x) devices
include all necessary circuitry to frame and format up
to 12 separate DS3 or E3 channels. Each framer in
these devices is independently configurable to
support M23 DS3, C-Bit Parity DS3, or G.751 E3.
The framers interface to a variety of line interface
units (LIUs), microprocessor buses, and other system
components without glue logic. Each DS3/E3 framer
has its own HDLC controller, FEAC controller, and
BERT, as well as full support for error detection and
generation, performance monitoring, and loopbacks.
