Monitoring Groomers
T1 32 Port Plus Groomer

The T1 Groomer (T1 Monitoring DACS) is capable of monitoring a -20dBdsx (0.3Volt Pulse) T1 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 RJ45 100 Ohms for T1 (and 120 Ohms for E1) and a "Y" cable is provided (included) to connect T1 Groomer equipment to the T1 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 T1 links that are being monitored, without limitation or restrictions, through the internal TSI non-blocking switch (data received by the equipment's 32 T1 receivers) and then aggregate the selected time-slots to the 4 output T1 ports that shall connect to the test probes etc.

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 -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 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.
