1.1 Overview

General

LRS-24 is a high-density SNMP managed modem chassis. The chassis has 12 slots

that accommodate up to 24 modems. Using modular interface cards, LRS-24 can

support xDSL, fiber or baseband modems in the same chassis under a single

management application.

Supporting different modem technologies enables a wide range of data-rates,

starting from 1.2 kbps in IDSL modems, through 2 Mbps with HDSL/fiber

modems, and up to 43 Mbps using fiber modems. This also enables ranges from

4.8 km at

2 Mbps over copper to 100 km over fiber modems.

LRS-24 is available in two different physical hub versions: LRS-24B (ANSI) or

LRS-24F (ETSI).

All cards can be replaced or cables removed during operation, without causing

interference to data transmission to/from other cards in the chassis.

Modular data interfaces allow modem connectivity via a wide range of data

interfaces. These include: V.24, V.35, X.21, RS-530, V.36, G.703 codirectional,

E1, built-in Ethernet bridge, or built-in IP router.

LRS-24 accepts a system clock via the DB-15 connector placed on the CM-2 card.
