Call to a DSS1 Terminal equipment on the S Bus (DDO)
The BRI-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. An external
fax server is an example of one such terminal.
A PISN user is created in the communication server for each outgoing direct dial-
ling number.
