DS2196 - T1 Dual Framer LIU

Description

The DS2196 T1 dual framer LIU is designed for T1 transmission equipment.

The DS2196 combines dual optimized framers together with a LIU.

Features

  • Two full-featured framers and a short/long-haul line interface unit (LIU) in one small package Based on Dallas Semiconductor’s single -chip transceiver (SCT) family Two HDLC controllers with 64-byte buffers that can be used for the FDL or DS0 channels Supports NPRMs and SPRMs as per ANSI T1.403-1998 Can be combined with a short/long-haul LIU or a HDSL modem chipset to create a low-cost office repeater/NIU/CSU, or a HDSL1/HDSL2 terminal unit with enhanced monitoring.

DS2196 T1 Dual Framer LIU www.maxim-ic.com GENERAL DESCRIPTION The DS2196 T1 dual framer LIU is designed for T1 transmission equipment. The DS2196 combines dual optimized framers together with a LIU. This combination allows the users to extract and insert facility data-link (FDL) messages in the receive and transmit paths, collect line performance data, and perform basic channel conditioning and maintenance. The DS2196 contains all of the necessary functions for connection to T1 lines whether they are DS1 long haul or DSX–1 short haul. The clock recovery circuitry automatically adjusts to T1 lines from 0ft to over 6000ft in length. The device can generate both DSX–1 line buildouts as well as CSU line buildouts of -7.5dB, -15dB, and -22.5dB.
