16 Port
Plus T1 Groomer
VCL-MegaConnect-Jr. for
Hi-Z Non-Intrusive Monitoring
Product Overview
The VCL-MegaConnect, 16 Port Plus T1
(also
available in E1) Monitoring Groomer is
suitable for non-intrusive monitoring of upto 8, "live" T1 traffic
links, bi-directionally (i.e. in both transmit and receive
directions through its 16 T1 receivers) through a high impedance
(Hi-Z) path. Additionally, the equipment also provides 4 output T1
ports that shall connect the aggregated time-slots which have been
non-intrusively "monitored" from the 8, "live" T1 traffic links to
the user's protocol analyzers, test probes, etc.
The VCL-MegaConnect, 16 Port Plus T1 Monitoring
Groomer, occupies only a 2U high rack-space, and is a compact
19-inch stand-alone unit. The unit is powered by and operates on a
-48V DC power supply. An AC mains option is also available with an
external AC-DC converter.
The equipment is provided with BOTH, RS232 Serial
Interface for COM Port connection and as well as a TCP/IP LAN
Interface (10BaseT) for providing equipment access through Telnet
over a LAN/TCI/IP link. The user may select and use either of these
ports for executing HyperTerminal text commands for configuration
etc. The access for configuration and system management is provided
through CLI (Command Line Interface) text commands which may be
executed either from a serial (COM) Port of a PC or through the
TCP/IP 10/100BaseT LAN Interface. The 10/100BaseT LAN Interface
allows the equipment to be connected on a TCP/IP network for remote
access for configuration and monitoring over LAN/TCP/IP link. The
system is also supplied with an easy to use Windows (95, 98, Me, XP)
Graphical User Interface that provides the user a complete control
to prepare multiple configuration "maps" and store them as easy to
read data files. Dry contact relay alarm output is also available at
rear of the system to connect the system to an external audio/visual
alarm output though a dry relay contact.
The Groomer is capable of non-intrusively
monitoring upto 8 "live" T1 links and grooming the selected 64 Kbps
time-slots to the 4 additional output T1 Ports provided in the
equipment. The 16, T1 receivers of the Groomer shall connect to the
8, T1 "live traffic" links which are to be monitored,
non-Intrusively. 4 additional (Normal-Z) output T1 Ports are also
provided by the equipment which shall route the aggregated data of
the "monitored" time-slots to the user’s test equipment, such as
protocol analyzers, test probes, billing servers etc.
The Groomer (T1 Monitoring DACS) is capable of
monitoring a -20dBdsx (0.3Volt Pulse) T1 signal through a Hi-Z path,
without in any way affecting or disturbing the "live" T1 traffic
that is required to be monitored.
The equipment offers the user with complete
flexibility to choose and select time-slots from each of the 8 T1
links that are being monitored, without limitation or restrictions,
through the internal TSI non-blocking switch (data received by the
equipment's 16 T1 receivers) and then aggregate the selected
time-slots to the 4 output T1 ports that shall connect to the test
probes etc.
The additional solutions are offered
and available for Hi-Z non-intrusive live traffic monitoring
applications are:
