VCL-MX Version 6 - E1 Multiplexer

Product Overview

Product Overview
VCL-MX Version 6 - 80 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 digitalaccess cross-connect equipment. Due to the
changing traffic patterns, there is a need to
support multiple services from the same
equipment like integrated data transport, better
network management etc. This necessitated
evolution to next generation E1 Multiplexer.

Redundant control card and power supply and
redundant control card options make it an ideal
solution for network service providers seeking to integrate and provide legacy and the next generation
services from a single platform.
Next generation E1 Multiplexer has emerged as one of the most economical and technologically viable
solutions for transmitting both (voice and data) over carrier networks. This technology offers savings
on investments / power and space to service providers.
Valiant Communications provides efficient solutions in this field using the E1 Multiplexer series
products. E1 Multiplexer provides a full range of solutions in this evolving field of next generation
telecom solutions. E1 Multiplexer family provides the unique advantage of carrying both voice and
data over PDH. In addition to being affordable, these products have built-in modularity, which allow
easy upgradeability. This upgradeability feature allows the customer to evolve in a “build-as-you-grow”
concept. Along with the Valiant Communications as Network Management solution the E1 Multiplexer
family provides the following features:

Toll Quality Voice Services

Interconnect LAN (Campus Network)
Interconnect computer terminals various types of data terminals
Provide LAN-WAN Inter-connectivity.

Chassis / System Backplane
All connections are made at the rear of the chassis, providing interconnections between the various
plug-in cards and to the network. VCL-MX Version 6 - E1 Multiplexer supports high-density PDH cards.
The line cards terminate a combination of Voice, Data and E1 Interfaces.
The VCL-MX Version 6 - E1 Multiplexer provides a host of features facility over a network of VCL-MX
E1 Multiplexers, for applications.
An extensive set of alarms, for easy maintenance are provided in the system.

System Management
VCL-MX Version 6 – Drop-Insert Multiplexer offers a variety of management options. The VCL-MX
Version 6 E1 multiplexer management software can be configured using CLI (English text) commands
and GUI (Graphical User Interface). The management and configuration commands may be executed
from a VT100 terminal, Windows HyperTerminal, any DOS based system, Linux or UNIX based
system, or Telnet (remote management).
The equipment provides a wide choice of access ports for connecting to and executing management
and configuration commands through its OAM Card.
The OAM card provides:
a)
b)
c)
d)
e)

COM Port (DB9, RS232 Serial Port).
USB Port
10/100BaseT Ethernet Port (each multiplexer may be assigned an IP address and connected to

a LAN / IP network for remote access and management through the 10/100BaseT Ethernet Port
for out-of-band management)
SNMP V2.
Additionally, a Windows-based GUI (Graphical User Interface) to access and manage the
equipment. The GUI may be installed on a Windows-based PC.

The VCL-MX has an effective, CLI (text) and GUI based "Network Management Interface", which may
be used for configuring and monitoring multiple systems from a single central location.
