32 Port E1 Groomer
Hi-Z Non-Intrusive Hi-Impedance
Monitoring Solution - 2U high
VCL-MegaConnect,
the E1 x 32 port Hi-Z Monitoring Groomer is available for special
non-intrusive monitoring (high impedance) applications in which E1
ports can be connected to monitoring / |
 |
| billing
equipment for non-intrusive monitoring of live traffic or
signaling, required by billing servers etc. |
The 32 E1 Ports Groomer
for monitoring provides upto 16 E1 links (32 E1 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, E1 Ports. 32, E1 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 E1 ports shall connect to the monitoring equipment, such as
billing servers etc.
The Groomer (E1 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 E1 traffic
that is required to be monitored. The E1 connector(s) shall be RJ45
100 Ohms (for E1) and 120 Ohms for E1 and a "Y" cable is provided
(included) to connect E1 (or T1) Groomer equipment to the E1 (or T1)
ports that are required to be monitored.
The user shall have the full flexibility to choose and select upto a
maximum of 31 time-slots (to be monitored in BOTH transmit and receive
direction), through the internal TSI non-blocking switch, from any of
the 24 E1 ports that are required to be monitored.
Additional solutions offered and
available for Hi-z Non-Intrusive Monitoring applications are:

Rear View
The VCL-MegaConnect, 32
Port E1 monitoring groomer, occupies only a 2U high rack-space, and is
a complete 19-inch standalone unit. The unit operates on a -48VDC
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 E1 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.
