Overview

The ISDN PC Adapter Circuit Extended IPAC-X integrates all necessary functions for a host based ISDN access solution on a single chip. It is based on the IPAC PSB 2115, combining the functions of ISAC-S PEB 2086 and HSCX-TE PSB 21525, with enhanced features and functionality.

It includes the S-transceiver (Layer 1), an HDLC controller for the D-channel and two protocol controllers for each B-channel. They can be used for HDLC protocol or transparent access.
