The Aethra® modular system TGA1012 for alarm signalling over E1/G.704 lines, is the best solution for continuous monitoring aimed to carriers, call center, ISPs, public offices and those who need constant monitoring of their lines. The system is modular as the basic unit may be equipped with a variable number of interface modules in order to manage up to a maximum of 12 primary lines. Moreover, these units may be connected in cascade through RS485 serial port, up to a maximum of 6 units for a total number of 72 lines.
In addition to the alarms signalling feature, TGA1012 allows the conversion between interfaces 120 Ohm - 75 Ohm and vice versa, both Network side and Terminal side without any extra piece of hardware.
By using external devices, e.g. the D2000PRO, it is possible to be connected to one of the access under control and carry out tests over the line both toward the network and toward the terminal, as well as performing a monitor test in high impedance.
Besides, the optional remote management software, will allow you to control the status of the lines connected to TGA1012, reproducing the device accurately on the screen of your PC.
The optional matrix MTX200, will improve the system management allowing remote automatic access switching, in order to monitor and test the problematic lines using just one external test equipment.
