Product Overview

Comarra's E1 Multiplexer the VCL-MX, 2Mbps E1 voice and data, drop-insert (add-drop) multiplexer provides full range of voice (POTS) and digital data services to subscribers located at different locations, requiring to interconnect and establish a voice and data network over an E1 link. The VCL-MX is available in 4 versions, each providing different features and voice / data interfaces.

The VCL-MX, E1, Drop-Insert Multiplexer provides voice telephony and digital data services which may include:

The Multiplexer may be used in Terminal or Drop-Insert configuration to provide:

• Toll Quality Voice services
• Interconnect LAN (Campus Network)
• Provide LAN-WAN Interconnectivity
• Provide Leased Lines on DSL for SOHO Applications

The VCL-MX has an effective, CLI (text) based "Network Management System", which may be used for configuring the system, subsequent remote monitoring and management of the inter-connected systems in the network. Both Inband and Out-Of-Band configuration and monitoring options are available. An extensive set of alarms, for easy maintenance are provided in the system.
