The E1 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 120 Ohms for E1 (and 100 Ohms for T1) and a "Y" cable is provided
(included) to connect E1 Groomer equipment to the E1 ports that are required to be
monitored.
The equipment offers the user with complete
flexibility to choose and select time-slots from each of the 16 E1
links that are being monitored, without limitation or restrictions,
through the internal TSI non-blocking switch (data received by the
equipment's 32 E1 receivers) and then aggregate the selected
time-slots to the 4 output E1 ports that shall connect to the test
probes etc.
Additional solutions offered and available for Hi-z
Non-Intrusive Monitoring applications are:
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.
Applications
- 32 Port (plus 4 ports for connecting to monitoring
equipment) E1 monitoring groomer
- Monitoring of “Live Traffic” on E1 links which are
to be monitored, non-intrusively (Hi-Z) in both transmit and receive directions.
Indications and Alarm Monitoring

Programmable Features
- Specifying the priority sequence for clock selection.
- Enabling or disabling E1 channels (masking) of the E1
channels that are not is use.
- Creating a cross - connect between E1s (and T1) at DS-O
level (single time-slot level) using the Windows based, easy to use GUI.
- Telnet interface for remote programming.
