Product Overview

The VCL-MegaConnect, 64 Port Plus - T1 Monitoring Groomer is suitable for non-intrusive monitoring of upto 32, "live" T1 traffic links, bidirectionally (i.e. in both transmit and receive directions through its 64 T1 receivers) through a high impedance (Hi-Z) path. Additionally, the equipment also provides 16 output T1 ports that shall connect the aggregated time-slots which have been non-intrusively "monitored" from the 32, "live" T1 traffic links to the user's protocol analysers, test probes, etc.

Description

The VCL-MegaConnect, 64 Port Plus - T1 Monitoring Groomer (PDF 368 KB), occupies only a 3U high rack-space, and is a compact 19-inch stand-alone unit. The unit is powered by and operates on a dual (1+1 protected) -48V DC power supply. An AC mains option is also available with an external AC-DC Converter.

64 Port Plus-T1 Monitoring Groomer - Data Sheet (PDF)

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/TCI/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. 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 as easy to read data files. Dry contact relay alarm output is also available at rear of the system to connect the system to an external audio/visual alarm output though a dry relay Contact.

The Groomer is capable of non-intrusively monitoring upto 32 "live" T1 links and grooming the selected 64 Kbps time-slots to the 16 additional output T1 Ports provided in the equipment. The 64, T1 receivers of the Groomer shall connect to the 32, T1 "live traffic" links which are to be monitored, non-Intrusively. 16 additional (Normal-Z) output T1 Ports are also provided by the equipment which shall route the aggregated data of the "monitored" time-slots to the userís test equipment, such as protocol analysers, test probes, billing servers etc.

The Groomer (T1 Monitoring DACS) is capable of monitoring a -20dBdsx (0.3Volt Pulse) T1 signal through a Hi-Z path, without in any way affecting or disturbing the "live" T1 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 32 T1 links that are being monitored, without limitation or restrictions, through the internal TSI non-blocking switch (data received by the equipment's 64 T1 receivers) and then aggregate the selected time-slots to the 16 output T1 ports that shall connect to the test probes etc.

Non-Intrusive Monitoring Applications

Where TP is testing T1 Point and MP is Monitoring T1 Point.

VCL-MegaConnect T1, 64 Port Groomer

Shelf Description

The VCL-MegaConnect T1, 64 Port Groomer unit is a 3U, 19-inch shelf, fitted with a backplane that provides rear access of all external interfaces. The 1.544 Mbps electrical I/Os, power input, alarm extension and the NMS port are all accessed from the backplane.
