interface is a 9-pin D-type female connector.
The SLTA option card can be connected to a remote host via the telephone network
and a pair of modems.
The SLTA option card also contains a fibre-optic transceiver pair of one of the
following types:
- ST-type glass fibre-optic transceiver
- snap-in-type plastic fibre-optic transceiver
The transceiver types are not interchangeable and have to be specified in the order.
