Description

•

Master (NT)/Slave (TE) modes of operation

Exceeds loop length requirements

The MT8930B Subscriber Network Interface Circuit

(SNIC) implements the CCITT I.430 and ANSI

T1.605 Recommendations for the ISDN S and T

reference points. Providing point-to-point and point-

to-multipoint digital transmission, the SNIC may be

used at either end of the subscriber line (NT or TE).

Complete loopback testing capabilities

On chip HDLC D-channel protocoller

8 bit Motorola/Intel microprocessor interface

Controllerless or microprocessor-controlled

operation

•

Mitel ST-BUS interface

An HDLC D-channel protocoller is included and

controlled through a Motorola/Intel microprocessor

port. A controllerless mode allows the SNIC to

operate without a microprocessor.

Low power CMOS technology

Single 5 volt power supply

Applications

The MT8930B is fabricated in Mitel’s CMOS process.
