UTEL's largest Intelligent Switch Matrix Controller (ISMC). Ideal for very large density sites with the six individual switch busses capable of controlling 30000 line circuits. A single ISMC is required per building to control all TASM equipment. The ISMC128ES has 2 seperate four wire testbuses, allowing it to switch two circuits to two Test heads simultaniously. The four wires split the circuit allowing true 2 wire look in and look out.
Supplied in a chassis suitable for rack mounting in a 19" or ETSI standard frame, this unit is normally installed at the top of the first rack. It is supplied with a TestBus Patch Panel, cables, and all connectors ready for installation.
The TestBus Patch Panel has an RJ45 dual TestBus socket and an associated 8 screw terminal connector to provide an easy means of connecting Testheads to the dual TestBuses.
Powered by -48V from the local exchange Bus. Configuration software for a laptop is provided free of charge and makes installation very straight forward.
All cables are standard CAT5 and are supplied with the product. Colour coding ensures the correct wiring is installed. Wiring follows standard diasy chaining and naturally flows down the cabinet to the test access switches.
