Product SummaryRAD's LRS-52 SHDSL modem rack is a dedicated chassis providing Symmetric High-Bitrate Digital Subscriber Loop (SHDSL) service within the Local Loop. The LRS-52 SHDSL modem rack provides a variety of options, making it suitable for a wide range of customers. Up to 24 SHDSL modems can be installed in a single LRS-52 SHDSL modem rack; the high density reduces the price per port. The LRS-52 SHDSL modem rack comes with an SNMP agent on board that provides simple and full management. Full diagnostics are also provided. When used in conjunction with the ASMi-52 SHDSL modem, the LRS-52 SHDSL modem rack provides a complete solution to deploying SHDSL services. Benefits• Operates over 2-wire and 4-wire lines, enabling service over any copper infrastructure • Utilizes TC-PAM line coding for extending the operating range to 9.5 km (5.9 miles) and eliminating the need for repeaters • Allows daisy-chaining of several units via Ethernet ports for uninterruptible management • Provides extensive diagnostics, including loopbacks, SHDSL and E1 performance monitoring Further Product InformationSHDSL modem rackThe LRS-52 is a manageable access system that offers a complete SHDSL solution in the Local Loop. Each port in the LRS-52 works opposite an SHDSL remote device in a point-to-point configuration, providing each port with an independent connection. The product supports SHDSL technology in full compliance with ITU and ETSI standards. The LRS-52 is a cost-effective non-modular modem rack that can be used with a dedicated number of ports. The user can choose between 12 and 24 ports in the 2-wire version, and between six and 12 ports in the 4-wire version. The LRS-52 is available in separate versions for each user interface (E1, V.35 or X.21). Built-in Ethernet bridge and Ethernet ports connect multiple chassisThe LRS-52 has an SNMP agent on board that provides full SNMP management of the central and the remote units. It includes a built-in Ethernet bridge and dual Ethernet ports for the connection of a large number of racks to single or multiple management stations. The same Ethernet segment used for managing the LRS-52 can be used to manage other elements in the network, such as backbone equipment, from the same management station. The LRS-52 has two additional ports, one for local ASCII terminal management and the other for station clock connection. The RADview SNMP application running on an HP OpenView or PC platform enables full management of the LRS-52 and the remote ASMi-52 SHDSL modem. The LRS-52 can operate with either a single or dual AC or DC power supply. Each power supply supports a working rack, enabling replacement during operation without any effect on system performance.
