Valiant's 4 x E1 Multiplexer the VCL-MX, 2Mbps E1 voice and data, drop-insert (add-drop) multiplexer  Version 3 (Deluxe Version) 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 3 versions, each providing different features and voice / data interfaces.

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

Advanced Features and Capabilities:

• 2Mbps, 4 E1 non-blocking cross-connect at 64Kbps (DS-0) level
• 1+1 Redundant Power Supply
• May be used in a Point-to-Point, Point-to-Multi point, Add-Drop (drop-insert), Tree and Star topology
• Telnet
• SNMP V2
• In-band and Out-of-band management
• GUI (Graphical User interface)
• Network Management System (Monitor and configure multiple units from a single central location)

Maintenance and Management features

• Serial Management Port (RS232) – COM Port

Analog I/O Interface Card (Dry Relay Contacts)

This interface card provides 8 Analog I/Os which may be used to extend either Dry Relay Contacts (Relay Normally-Open or Relay Normally-Close) or operate switches remotely (using 2A Dry Relay Contacts) between any two multiplexers using a 64 Kbps time-slot. The Dry Relay Contacts are rated at maximum 2 Amps, 30 Volts DC. 

Digital I/O Interface Card (Digital TTL Signal Transfer Card)

This interface card provides 8 digital I/Os which may be used to either extend digital I/O’s (logic high / low) signals between any two E1 Multiplexers or operate switches remotely (using logic high/low) signals between any two multiplexers. Drivers / Sense Logic operate using external voltage and ground references).

Universal Data Interface Card:

V.35 / V.36 / RS422 / V.11 / RS530 / X.21, DTE/DCE, "N" x 64Kbps Synchronous Data Interface, ONE Interface per Card - User Selectable Data Rate of "N" (1 thru 30) - DCE or DTE (User Configurable).
