32 Port
T1 Groomer
Hi-Z Non-Intrusive Hi-Impedance
Monitoring Solution - 2U high
| VCL-MegaConnect,
the T1 x 32 port Hi-Z Monitoring Groomer is available for
special non-intrusive monitoring (high impedance) applications
in which T1 ports can |
 |
| be connected to monitoring / billing equipment for
non-intrusive monitoring of live traffic or signaling, required
by billing servers etc. |
The
32 T1 Ports
Groomer for Monitoring (PDF) provides upto 16 T1 links (32 T1
Ports) plus 4 additional spare E1 ports (Normal-Z) to connect to the
measurement-probe, billing servers etc.
In the monitoring mode
the groomer provides the user a total of 32, T1 Ports. 32, T1 ports
shall connect to the “live traffic” E1 links which are to be
monitored, non-intrusively (Hi-Z) in both transmit and receive
directions. 4 additional T1 ports shall connect to the monitoring
equipment, such as billing servers etc.
The Groomer (T1
Monitoring DACS) is capable of monitoring a -20dBdsx (0.3Volt Pulse)
E1 signal through a Hi-Z path, without in any way disturbing the
live T1 traffic that is required to be monitored. The T1 connector(s)
shall be RJ-45 100 Ohms (for T1) and 120 Ohms for E1 and a "Y" cable
is provided (included) to connect T1 (or E1) Groomer equipment to
the T1 (or E1) ports that are required to be monitored.
The user shall have the full flexibility to choose and select upto a
maximum of 24 time-slots (to be monitored in both transmit and
receive direction), through the internal TSI non-blocking switch,
from any of the 32 T1 ports that are required to be monitored.
Additional solutions
offered and available for Hi-Z Non-Intrusive Monitoring applications
are:

The VCL-MegaConnect, 32
Port T1 monitoring groomer, occupies only a 2U high
rack-space, and is a complete 19-inch standalone unit. The unit
operates on a -48V DC input power-supply (AC input adapter is
optional for AC mains operation).
The system is 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. It may also accessed using CLI (Command Line Interface)
through a Serial (COM) Port of a PC using HyperTerminal text
commands. Dry contact relay alarms are also available at rear of the
system to connect the system to external audio and visual alarms
outputs.
The VCL-MegaConnect, 32
Port T1 monitoring groomer also has a TCP / IP Access feature
which allows the DACS to be connected on a TCP / IP network (10 / 100
Base Interface) for remote access for configuration and monitoring
using Telnet.
