32 Port Plus - T1 Monitoring Groomer Hi-Z Non-Intrusive
Hi-Impedance Monitoring Solution - 2U High

Product Overview

AceCom's MegaConnectTM 32 Port Plus - T1 Monitoring Groomer is suitable for non-intrusive monitoring of upto 16, "live" T1 traffic links, bi-directionally (i.e. in both transmit and receive directions through its 32 T1 receivers) through a high impedance (Hi-Z) path. Additionally, the equipment also provides 4 output T1 ports that shall connect the aggregated time-slots which have been non-intrusively "monitored" from the 16, "live" T1 traffic links to the user's protocol analyzers, test probes, etc.

The 32 Port Plus T1 Groomer for Monitoring provides upto 16 T1 links (32 T1 Ports) plus 4 additional spare T1 ports (Normal-Z) to connect to the measurement-probe, billing servers etc.

The equipment is provided with BOTH, RS232 Serial Interface for COM Port connection and 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. 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 an external audio/visual alarm output through a dry relay contact.

The T1 Groomer is capable of non-intrusively monitoring upto 16 "live" T1 links and grooming the selected 64 Kbps time-slots to the 4 additional output T1 Ports provided in the equipment. The 32, T1 receivers of the Groomer shall connect to the 16, T1 "live traffic" links which are to be monitored, non-Intrusively. 4 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 user’s test equipment, such as protocol analyzers, test probes, billing servers etc.

The T1 Groomer (T1 Monitoring DACS) is capable of monitoring a -20dBsx (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 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.
