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.

Description

The ATLB board contains circuitry for connection of 6 2-wire telephones as AlphaCom subscribers. The board also provides one measurement channel for voice switching control. It plugs into any position 1 - 23.

When the hot-line function is activated for the station a preprogrammed number is dialed when the handset is lifted. When the handset is replaced, another number is dialed.

The board provides 6 remote control outputs RCO that are software-controlled (4 RCO's in AlphaCom E7). The line monitoring reports errors on all subscriber lines. If the handset is left off for 1 hour (programmable timer) a line error is reported.

The board can be plugged in/out while the exchange is running. A hot plug-in cable is needed for this purpose. The cable is included in the cable set for the exchange.
