Data Interfaces
For data traffic, it supports the following interfaces:
• Channelized E1 / Fractional E1 data with full cross-connect capability at 64Kbps, DS-0 level
• RS-232 asynchronous data
• Sub-rate multiplexing to provide 4 asynchronous data channels in a single 64Kbps time-slot
• V.24 synchronous data / asynchronous data
• G.703, @ 64 Kbps, co-directional
• V.35, V.36, X.21, V.11, RS530, RS449 synchronous, “n”x64Kbps data
• BRI ISDN “U” Interface
• Relay I/O Card (Dry Contact)
• IEEE C37.94 Teleprotection Interface
• Universal DCE/DTE synchronous “n”x64Kbps data interface
• 8E1 plus 100Mbps Ethernet fiber optical (1+1) protected transport interface
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 160Mbps Multiplexer and supports high-
density PDH cards. The line cards terminate a combination of Voice, Data and E1 Interfaces.
The VCL-MX E1 Multiplexer has a 160 MBits/sec backplane and provides a host of features including,
channel drop and insert facility over a network of VCL-MX E1 Multiplexers, for voice and data
applications.
An extensive set of alarms, for easy maintenance are provided in the system.
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:
a) COM Port (RS232 Serial Port).
b) USB Port
c) 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).
d) Telnet
e) SSH
f) SNMP, V2
g) 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.
