VCL-HSL (High-Speed Signaling Link) 

64 E1 Port Hi-Z Monitoring Equipment

 

 

Product Overview

Orion Telecom Networks Inc. offers the VCL-HSL (High-Speed Signaling Link) 64 E1 Port Hi-Z Monitoring Equipment is suitable for "non-intrusive" monitoring applications and may be used to monitor upto 32, "live" HSL E1 (High Signaling Link) traffic links in both transmit and receive directions.

Description

The VCL-HSL 64 E1 Port Hi-Z Monitoring Equipment is equipped with 64 E1 receive ports, through which the attenuated "tapped / monitored" signal of the 32 "live" HSL E1 links" is input from a high impedance (Hi-Z) point of a DDF / patch-panel. The equipment also provides 64 E1 transmit (output) ports from where the regenerated and reproduced E1 "monitored" link output is obtained by the user to connect to protocol analysers, test probes, billing servers etc. as a normal E1 output.

The VCL-HSL 64 E1 Port Hi-Z Monitoring Equipment is capable of monitoring an attenuated -20dBdsx (0.3 Volt Pulse) E1 signal received through a Hi-Z path, without in any way affecting or disturbing the "live" E1 traffic on the "live" E1 links which are being monitored.

The VCL-HSL 64 E1 Port Hi-Z Monitoring Equipment, occupies only a 2U high rack-space, and is a compact 19-inch stand-alone unit. The unit is powered by and operates from a -48V DC power supply.

An AC mains option is also available with an external AC-DC adapter.

The equipment is provided with an RS232 as well as a USB serial data interface for local equipment access and management through a serial data port. The equipment is also provided with a 10/100BaseT Ethernet interface for remote equipment access over a TCP/IP link.

The access for configuration and system management is provided through CLI (Command Line Interface) text commands which may be executed either from a serial (COM) Port of a PC or through the TCP/IP 10/100BaseT LAN Interface. The 10/100BaseT LAN Interface allows the equipment to be connected on a TCP/IP network for remote access for configuration and monitoring over a TCP/IP link.

The equipment supports SNMP V2 Trap monitoring.

The system is also supplied with an easy to use Windows XP and Windows 7 compatible Graphical User Interface for easy equipment control and management.

Dry contact relay alarm output is also available at rear of the system to connect the system to an external alarm output though a dry relay contact.

Internal resistive high-impedance isolation may also be used in the equipment to eliminate the requirement of an external patch panel with high-impedance Protective Monitoring Points (PMP).

Shelf Description:

VCL-HSL 64 E1 Port Hi-Z Monitoring Equipment is a 2U,  19 Inch Shelf, fitted with a backplane that provides rear access of all external interfaces, including the E1 2 Mbps electrical I/Os, safety ground and external alarm extension connectors. The system management and control interfaces are provided on the front panel for easy operator access.

The E1 2 Mbps, Input and the Output Interfaces are 120 Ohms, terminated on DB-37 connectors in the 19-inch 2U high version of the equipment.
