Meridian Data Services Description
ADM
In the co-located mode, the ADM operates in conjunction with an SL-1
telephone to provide the interface with data terminal equipment in cases
where
• both voice and data calling are required
• answer-and-originate data calling capabilities are required
In stand-alone mode (no companion SL-1 telephone), the ADM supports
incoming data calls where no voice calling or data-call originating
capabilities are required (for example, computer ports and modems).
AIM
The AIM and its associated AILC port supports all types of outgoing and
incoming data calls where no voice calling or data-call originating
capabilities are required (for example, computer ports and modems).
ASIM
The ASIM supports all types of asynchronous and synchronous outgoing and
incoming data calls. Either keyboard or keypad dialing is used to establish the
asynchronous outgoing connections while only keypad dialing may be used
to establish synchronous outgoing connection.
Power supply
Power for each module is supplied externally as follows:
• One external power unit is required to provide local 24 V input to each
ADM or AIM. A 110 or 220 V ac to 24 V transformer must be used. Use
a P0593922 or P0610756 24 V transformer for the ADM. The A0290050
24 V transformer is recommended for use with the AIM.
• One external power supply (A0297998) is required for each ASIM. A
110 V ac input service should be used. An optional 220 V power supply
(A0318291) is available for the international market. The ASIM power
supplies are assembled with the units and it is not necessary to order them
separately.
