Description
The ATLB-12 card is a high capacity analogue telephone line card supporting 12 subscriber lines. The subscribers have access to all STENTOFON AlphaCom telephone features. A hot-line function is available for connection of telephones without dial buttons. When the handset is lifted, a preprogrammed number is dialed. This can be a call to another subscriber or activation of a function in the exchange. The board provides 6 configurable remote control outputs for interfacing of external equipment such as strobe lights, PA control signals and more. The card can be inserted in position 1-6 in the AlphaCom E7 exchange, and position 1-23 in the AlphaCom E20 and E26 exchanges. In AlphaCom E20 and E26 exchanges, the board can be plugged in or out while the exchange is running using the board hot-swap function.
