5.3.5 Call to a DSS1 Terminal equipment on the S Bus (DDO)
The S external interface can be used to address a terminal equipment that has its
own direct dialling plan. The system dials the terminal's end destinations using
DDI numbers, which is equivalent to a DDO (direct dialling out) function. A fax
server is an example of one such terminal.
A PISN subscriber is created in the PBX for each outgoing direct dial number.
