64 Port
Plus - T1 Monitoring GROOMER
Hi-Z Non-Intrusive
Hi-Impedance Monitoring Solution
Product Overview
| The VCL-MegaConnect, 64 Port Plus - T1 Monitoring
Groomer is suitable for non-intrusive monitoring of upto 32, "live"
T1 traffic links, bidirectionally (i.e. in both transmit and receive
directions through its 64 T1 receivers) through a high impedance
(Hi-Z) path. Additionally, the
equipment |
 |
|
also provides 16 output T1 ports
that shall connect the aggregated time-slots which have been
non-intrusively "monitored" from the 32, "live" T1 traffic links
to the user's protocol analysers, test probes, etc. |
Description
The VCL-MegaConnect, 64 Port Plus - T1 Monitoring
Groomer (PDF 368 KB), occupies only a 3U high rack-space, and is a compact
19-inch stand-alone unit. The unit is powered by and operates on a
dual (1+1 protected) -48V DC power supply. An AC mains option is
also available with an external AC-DC Converter.
The equipment is provided with both, RS-232 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 32 "live" T1 links and grooming the selected 64 Kbps
time-slots to the 16 additional output T1 Ports provided in the
equipment. The 64, T1 receivers of the Groomer shall connect to the
32, T1 "live traffic" links which are to be monitored,
non-Intrusively. 16 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 analysers, 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 32 T1
links that are being monitored, without limitation or restrictions,
through the internal TSI non-blocking switch (data received by the
equipment's 64 T1 receivers) and then aggregate the selected
time-slots to the 16 output T1 ports that shall connect to the test
probes etc.
