Monitoring Groomers
16/32 E1 Packet Monitoring

The E1 Groomer are capable of monitoring a -20dBdsx (0.3Volt Pulse) E1 signal through a Hi-Z path, without in any way distrubing the live E1 traffic that is required to be monitored. The E1 connector(s) shall be RJ45 120 Ohms 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 8 E1 links that are being monitored, without limitation or restrictions, through the internal TSI non-blocking switch (data received by the equipment's 16 E1 receivers) and then aggregate the selected time-slots to the 4 output E1 ports that shall connect to the test probes etc.

The VCL-MegaConnect, 16 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, 16 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.
