Description

The PM6388-RI is an electronic component model that falls under the product category of IC chips. Efficiently integrating eight E1 framers in a single device. The device is designed to terminate duplex E1 signals, transfer PCM data to/from 2.048 MHz system-side devices, and support fractional E1. It also provides optional backplane interfaces compatible with Mitel ST®-bus, AT&T CHI® and MVIP PCM backplanes that support data rates of up to 2.048 Mbit/s and 8.192 Mbit/s. Additionally, this model extracts and inserts up to three HDLC links from/to arbitrary time slots to support ISDN Primary Rate Interfaces and V5.1/V5.2 interfaces. It also offers per-channel payload loopback and per-link diagnostic and line loopback functionalities. The device is available in a 128 pin PQFP package, with a -40°C to +85°C Industrial temperature operating range.
