Valiant offers a wide range of STM-1, E1 and T1 Groomers for non-intrusive monitoring applications. The VCL-MegaConnect STM-1, E1 and T1, Hi-Z Monitoring Groomers may be used for non-intrusive monitoring of "live" STM-1, E1 and T1 traffic links, non-intrusively, through a high impedance monitoring point on a patch panel or a DDF. The equipment also allows the user to groom the selected time-slots carrying the monitored data to selected STM-1, E1 or T1 normal impedance ports which can be connected to protocol analysers, probes, test equipment, billing servers etc.

E1 VCL-MegaConnect Groomer offers bidirectional monitoring and unidirectional monitoring modes.

Solutions offered and available for Hi-z Non-Intrusive Monitoring applications are:

Product Description:

The VCL-MegaConnectTM, 64 Port E1 Groomer, occupies only a 6U high rack-space, and is a compact 19-inch stand-alone unit. The unit operates on a -48VDC input power-supply. An AC input adapter is also optionally available for AC mains operation. The equipment is provided with both, RS232 Serial Interface for COM Port connection and as well as a TCP/IP LAN Interface (10BaseT) for providing equipment access through Telnet over a LAN/TCP/IP link. The user may select and use either of these ports for executing HyperTerminal text commands for configuration etc. The access for configuration and system management is provided through CLI (Command Line Interface) text commands which may be executed either from a serial (COM) Port of a PC, or through the TCP/IP 10/100BaseT LAN Interface.

The 10/100BaseT LAN Interface allows the equipment to be connected on a TCP/IP network for remote access for configuration and monitoring over LAN/TCP/IP link, remotely. The system is also 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. Dry contact relay alarm output is also available at rear of the system to connect the system to external audio/visual alarm output though a dry relay contact.

Bidirectional Monitoring

In bidirectional mode the groomer is capable of non-intrusively monitoring upto 30 "live" E1 links and then groom the selected time-slots to the 4 E1 Ports provided in the equipment. The 60, E1 receivers of the groomer shall connect to the 30, E1 "live traffic" links which are to be monitored, non-intrusively.

The Groomer is capable of monitoring a -20dBdsx (0.3Volt Pulse) E1 signal through a Hi-Z path, without in any way affecting or disturbing the "live" E1 traffic that is required to be monitored.

The equipment offers the user with complete flexibility to choose and select time-slots from each of the 30 E1 links that are being monitored, without limitation or restrictions, through the internal TSI non-blocking switch (data received by the equipment's 60 E1 receivers) and then aggregate the selected time-slots to the 4 E1 ports that shall connect to the test equipment, such as protocol analysers/test probes, billing servers etc.

Unidirectional Monitoring

In unidirectional mode the Groomer is capable of non-intrusively monitoring upto 60 "live" E1 links and then groom the selected time-slots to the 4 E1 Port provided in the equipment. The 60, E1 receivers of the Groomer shall connect to the 60, E1 "live traffic" links which are to be monitored, non-intrusively.
