MT8931B - Subscriber Network Interface Circuit

General Description

The MT8931B 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 pointto-multipoint digital transmission, the SNIC may be used at either end of the subscriber line (NT or TE).

Key Features

  • CCITT I.430 and ANSI T1.605 S/T interface Full-duplex 2B+D, 192 kbit/s transmission Link activation/deactivation D-channel access contention resolution Point-to-point, point-to-multipoint and star configurations Master (NT)/Slave (TE) modes of operation Exceeds loop length requirements ISSUE 2 August 1993 Ordering Information MT8931BC 28 Pin Ceramic DIP MT8931BE 28 Pin Plastic DIP MT8931BP 44 Pin PLCC -40°C to +85°C Descrip.
