MS+A1-4
Field of Application
The MT+A1-4 provides interface card four analogue interfaces for connecting
analogue trunk lines.
The MT+A1-4 interface card can be installed in any of the slots (1 to 12) of the
OpenCom 510 (see
Slots
starting on page 27).
Technical Information
The MT+A1-4 interface card can also be installed in a slave system.
The MT+A1-4 interface card supports pulse dialling as well as dual-tone multi-
frequency (DTMF) dialling.
Ringing tone detection works at 16

, 25 or 50 Hz. The analogue network ter-
minations are electrically isolated. The country-specific adaption is made by
the operating software.
Calling line identification presentation (CLIP), the consultation feature by
means of a flash key and/or earthing key and the transmission of call data
charges are not supported.
The MT+A1-4 interface card runs on software acquired from the system. After
the card has been installed it will automatically load the required software.
No settings need to be made on the MT+A1-4 interface card.
Pin Assignment
For information on the a/b interface pin assignment, refer to
a/b Ports
starting on
page 48.
Indicators
There are four LEDs on the front of the MT+A1-4 interface card.
