64 Port Plus - E1 Monitoring Groomer
Hi-Z Non-Intrusive Hi-Impedance Monitoring Solution

Product Overview

AceCom offers the MegaConnectTM 64 Port Plus - E1 Monitoring Groomer is suitable for non-intrusive monitoring of up to 32, bi-directional "live" E1 traffic links (i.e. in both transmit and receive directions) through its 64 E1 receivers. The Groomer is capable of receiving the “monitored” E1 signal inputs through the high impedance (Hi-Z) path of a patch-panel, without in any way disturbing the “live” E1 traffic links. The Groomer provides the “user” the facility to cross-connect 64Kbps time-slots through a completely “non-blocking” TSI switch, through which the selected SS7 signaling time-slots on the INPUT side E1 Ports can be connected to the OUTPUT side E1 Ports. The equipment provides 16 E1 Ports on the OUTPUT side from where the selected / cross-connected / aggregated SS7 time-slots may be connected to the protocol analysers, test probes, etc.

The 64 Port Plus E1 Hi-Z Non Intrusive Monitoring Groomer 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 redundant) -48V DC power supply. An AC input adapter is also optionally available for AC mains operation.

The equipment is provided with a USB and an RS232 Serial Interface for COM Port connections as well as a TCP/IP LAN Interface (10/100BaseT) for providing equipment access through Telnet over a 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 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 and TCP/IP link, remotely. The system is also supplied with an easy to use (Windows XP, Windows 7) 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 external audio/visual alarm output through a dry relay contact.

The E1 Groomer is capable of non-intrusively monitoring upto 32 "live" E1 links and grooming the selected 64 Kbps time-slots to the 16 additional output E1 Ports provided in the equipment. The 64, E1 receivers of the Groomer shall connect to the 32, E1 "live traffic" links which are to be monitored, non-Intrusively. 16 additional (Normal-Z) output E1 Ports are also provided by the equipment which shall route the aggregated data of the "monitored" time-slots to the user’s test equipment, such as protocol analyzers, test probes, billing servers etc.

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

Alternately, the E1 Groomer (E1 Monitoring DACS) may be also ordered in an “extreme” sensitivity version which is capable of monitoring a -30dBsx signal (0.1 Volts) and a -40dBsx signal (0.03 Volts), through a Hi-Z patch-panel, without in any way affecting or disturbing the "live" E1 traffic that are being monitored.

The extreme sensitivity version of the E1 Groomer provides the user with a signal equalizer and a wave-shaper option to handle very low / attenuated E1 input signals.

The equipment offers the user with complete flexibility to select and cross-connect time-slots from each of the 32 E1 links that are being monitored, without limitation or restrictions, through the internal TSI non-blocking switch. Any of the 64 Kbps time-slots on any of the “input” (monitoring-MP) ports can be cross-connected and aggregated to any “output” (test-TP) port.

The additional solutions are offered and available for Hi-Z non-intrusive live traffic monitoring applications are:
