CN8330

DS3/E3 Framer with 52 Mbps HDLC Controller

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.

The CN8330 provides framing recovery for M13, C-bit parity, Syntran, and G.751

E3 formatted signals. A First In First Out (FIFO) buffer in the receive path can be

enabled to reduce jitter on the incoming data. Transmit and receive data is available to

the host in either serial or parallel byte and nibble formats. Access is provided to the

terminal data link and the Far End Alarm/Control (FEAC) channel, as specified in

T1.107a-1989. Counters are included for frame-bit errors, Line Code Violations

(LCVs), parity errors, and Far End Block Errors (FEBEs).

Distinguishing Features

•

Supports DS3/E3 framing modes

Includes high-speed HDLC controller

(52 MHz)

•

Framing recovery for M13, C-bit

parity, Syntran, and G.751 E3 signals

Serial or parallel (octet or nibble)

interface modes

Average reframe time of less than

1 ms for DS3 and less than 250 µs

for E3

•

Supports the LAPD terminal data link

and FEAC channel as defined in

T1.107a-1989

Two operational modes are available: microprocessor and stand-alone monitor

control modes. The microprocessor control mode monitors all status conditions and

provides configuration control. The stand-alone monitor mode allows the CN8330 to

operate as a monitor providing status and alarm information on external pins.
