modem rack, as well as some typical applications. The following topics are
discussed:
• Overview
• Physical Description
• Functional Description
• Technical Specifications.
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.
