Patching Features

Patching is a traditional manual patching system which provides front panel access to data communications channels by simply inserting patch cords or operating A/B switches and following established procedures. Patching is available to meet the requirements of most small to medium sized network control functions and is available in modular form based generally around a 16-channel 19" racking practice.

A/B Switching Features

A/B Switching is normally combined with the traditional manual patching system and provides a facility for enabling sparing of DTE or DCE equipment through the use of a toggle switch and electromechanical latching copper relays. A/B switching systems can also optionally provide an interface alarm functionality. The A/B switching function can be completely manual on a channel by channel basis or the switches can be controlled remotely. Remote control can be simply gang switching of up to 16 channels at a time or complete system switching can be controlled via an ASCII terminal or a proprietary management system.
