1-2 LRS-24 Overview LRS-24 RADview/TDM
LRS-24 can also be managed from an ASCII terminal. It allows all functions of
SNMP except for GUI interface. The connection is made via a V.24 supervisory
port using SLIP or PPP.
Telnet support enables terminal connection over any IP network.
The CM-2 panel includes an alphanumeric display with two characters used for
alerting on fault conditions and for the hub IP address.
Power Supplies
LRS-24 operates with single or dual, AC or DC power supplies. Each power supply
supports a full LRS-24 hub, including modem cards. Redundant power supply can
be replaced during operation, without affecting system performance
(hot-swapping).
Cards in the LRS-24 chassis are capable of providing remote power feeding for
repeaters and remote standalone modems. To provide remote power feeding
order a separate standalone power supply, LRS-PS-FEED.
Product Options
Two different physical versions of the LRS-24 hub are available:
• ANSI − card insertion, LEDs and switches are at the front, but cable
connections are at the rear of the hub. This compact, 4U high unit complies
with the American ANSI standard. Cards can be hot-swapped without
removing cables.
• ETSI − card insertion, LEDs, switches and cable connections are at the front.
This version is 30 cm high (almost 6U), and complies with European ETSI
standard. Cards can be hot-swapped without removing cables.
