LRS-16 managed SHDSL Modem Concentrator from RAD 

LRS-16 Managed SHDSL Modem Concentrator key features  include:
- Transparent modem concentrator with SNMP management
- E1 services over 16 SHDSL 2-wire lines
- Multiple data rates between 64 kbps and 2048 kbps
- Convenient and low-cost maintenance on PC or UNIX (HPOV) platforms using RADview SNMP management
- ASCII terminal or Telnet management
LRS-16 managed SHDSL Modem Concentrator from RAD
RAD's LRS-16 is a high-density SNMP managed modem concentrator. The chassis accommodates 16 fixed SHDSL modems, providing E1 services over 2-wire lines. LRS-16 employs standard SHDSL TC-PAM16 technology to extend the transmission range, thus enabling carriers to reach more customers at lower costs.

The LRS-16 uses an Embedded Operation Channel (EOC) for controlling and monitoring the remote unit. The management channel uses SHDSL overhead bits in compliance with ITU-T G.991.2 requirements, and operates without interfering with the data transmission.

The SHDSL port can be ordered with either 8 x RJ-45 connectors or 2 x DB-26 connectors convertible to 8 x RJ-45 via adaptor cable. In the latter case, the Ethernet ports are available with either 2 UTP or 1 UTP + 1 fiber-optic (SFP) connectors. The device with 8 x RJ-45 connectors is always supplied with 2 UTP connectors on the Ethernet ports.

LRS-16 is supplied in a 1U-high 19-inch enclosure.
Typical application for the LRS-16 SHDSL concentrator
RAD's LRS-16 TIMING
Each of the 16 ports inside the LRS-16 CO device can be separately clocked and locked on one of the following timing clock sources:
-  Internal, derived from LRS-16ís internal oscillator
-  External, supplied by the E1 port interface.
-  System, supplied by the station clock input.

LRS-16 has a station clock connection enabling clock distribution to all ports, so that all ports can be synchronized to the same station clock.

LRS-16 POWER SUPPLIES
LRS-16 operates with single or dual power supplies. A power supply can be hot-swapped (replaced) during operation, without affecting system performance.

MANAGEMENT OF LRS-16
LRS-16 is managed by a UNIX- or PC-based SNMP management system. The user-friendly software is GUI-based and runs on PC/Windows or HP-OpenView platforms. The SNMP management session can run over a 10/100BaseT Ethernet port.

Network management allows centralized control of all LRS-16 hubs, modem ports and remote modems in the network, including interface configuration, connection setup, alarms and monitoring. A single management station can control up to 64,000 LRS-16 hubs.

LRS-16 can also be managed from an ASCII terminal that performs all SNMP functions without a GUI.

Telnet allows terminal connection over any IP network.

The LRS-16 front panel features a two-digit alphanumeric display. When there are multiple hubs in the network, this display shows the number of the hub that can be configured by the user during normal operation.

LRS-16 SHDSL DIAGNOSTICS
RAD's LRS-16 features comprehensive diagnostic capabilities activated from either the ASCII terminal or an SNMP management tool. They include the following test options:
- Local analog and remote digital loopbacks
- SHDSL statistics collection for line performance monitoring
- E1 performance statistics per ITU-T G.706 requirements.

Performance information for the last 24 hours is available in graph and table format and can be saved in a file for accounting purposes.
