Equipment description
Configuration
Asynchronous Interface Line Card
553-2731-100
Standard 5.00
The AIM provides the interface between an RS-232-C compatible
asynchronous DTE through its AILC.
The connection to the AILC is made via a miniature 6-position jack mounted
on the rear of the housing. The module is equipped with a 7 ft (3.1 m)
6-conductor cord that is terminated with miniature 6-position plugs on each
end. The connection to the 110/220 V ac transformer is made with a 7 ft
(3.1 m) 2-conductor cord that is attached to the rear of the unit.
The AIM can only be connected to the AILC. It cannot be connected to the
DLC.
The AIM connects to the DTE through a 25-pin connector (that conforms to
ISO-2110) that is mounted on the rear of the housing.
AIM can be connected in the back-to-back mode if the send pairs of one set
are connected to the receive pairs of the other set and vice versa.
The AILC contains all the intelligence for the AIM. It is located in a PE shelf
and is used with and encodes information streams received from the AIM. It
routes this information through the Meridian 1 switching network to the
called data facility (computer or terminal).
Note: The AILC may also be used to connect the Meridian 1 switching
machine terminals, protocol converters, interface boards, X.25 gateways,
and other data transmission devices that use an RS-422 compatible
interface.
The AILC supports up to four AIM units. Each of the four channels has a
microprocessor that emulates the ADM to the Meridian 1 system, a switching
power supply, and other electronic components. The transmission between
the AIM and the AILC conforms to EIA RS-422 standards.
