The CN8330 is an integral DS3/E3 framer designed to support the transmission formats defined by ANSI T1.107-1988, T1.107a-1989, T1.404, and ITU-T G.751 standards. All maintenance features required by Bellcore TR-TSY-000009 and AT&T PUB 54014 are provided. In addition, the CN8330 can be optionally configured as a High-Level Data Link Controller (HDLC) usable with or without DS3/E3 framing overhead.
