M29320

12-Port DS3/E3/STS-1 Electrical Integrated Line Termination Device for Transport Networks


Overview

Description

The M29320 provides a complete physical-layer solution for flexible high-bandwidth DS3/E3 services, including secure private leased lines and video conferencing. The M29320 replaces up to 3 discrete devices, enabling coste-ffective DS3/E3 services to be deployed in both new and existing platforms.

The M29320 includes 12 independent DS3/E3/STS-1E electrical line interface units (LIUs) with built-in digital jitter attenuators (DJAT), 24 DS3/E3 framers (12x in receive and 12x in transmit for monitoring only), and 12 STS-1 framers. Each port is capable of supporting DS3/E3/STS-1E mapped/demapped signals to/from SONET/SDH interface.
