Product Summary

The PEB3086FV1.4 is designed as one kind of ISDN Subscriber Access Controller that is based on the ISAC-S PEB 2086, and provides enhanced features and functionality. This device includes the S-transceiver (Layer 1), an HDLC controller for the D-channel and one B-channel protocol controller (HDLC or transparent) with advanced CMOS technology. The ISDN Subscriber Access Controller ISAC-SX integrates a D-channel HDLC controller and a four wire S/T interface used to link voice/data terminals to the ISDN. It is the successor of the ISAC-S PEB 2086 in 3.3 V technology. It includes the S-transceiver (Layer 1), an HDLC controller for the D-channel and one Bchannel protocol controller (HDLC or transparent) with reduced features dedicated for firmware download via the B-channel. The system integration is simplified by several configurations of the parallel microcontroller interface selected via pin strapping.

Parametrics
