| The VCL-MegaConnect,
64 Port Plus - T1 Monitoring Groomer, 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, 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
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.

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.
