VCL-MX Version 5, 12 E1 Voice and Data Multiplexer

VCL-MX Version 5 - 12 x E1 Multiplexer is a carrier class and cost-effective bandwidth provisioning equipment designed to manage and deliver services from the optical core to the access.

VCL-MX Version 5 – 12 x E1 Multiplexer may be used for inter-connecting legacy voice and data networks, provisioning and managing bandwidth on a E1 channelized level as well as 64Kbps, DS-0 time-slot level and as a digital-access cross-connect equipment. This 12 x E1 Multiplexer can be used in a Point-to-Point, Point-to-Multi point, Add-Drop (drop-insert), Tree and Star topology applications. Offers and supports telnet, SNMP V2, GUI, In-band and Out-of-band management options.

The VCL-MX, 12 x 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

New interfaces

Analog I/O Interface Card (Dry Relay Contacts) (VCL-MX-047):
Description: 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. Each chassis shall accept a maximum of 3 such analog or digital I/O interface cards. (Available with VCL-MX, Version 5).

Digital I/O Interface Card (Digital TTL Signal Transfer Card) (Part # VCL-MX-048):
Description: 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). Each chassis shall accept a maximum of 3 such analog or digital I/O interface cards. (Available with VCL-MX, Version 5). 

Universal Data Interface Card: V.35 / V.36 / RS485 / V.11 / V.28 / 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). (Available with VCL-MX, Version 3).
