VCL-MX
Version
6,
Upto 80 E1 Voice and
Data Multiplexer |
Description
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 digital-access 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 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.
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 data and
voice over PDH.

System Management
VCL-MX Version # 6
- Voice and Data Drop-Insert
Multiplexer offer a variety of management options, The VCL-MX 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:
- COM Port (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 configuration, management and access)
Telnet
SSH
SNMP, V2
Additionally, a Windows based GUI (Graphical User
Interface) for easy configuration, management and access.
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.
