Basic accesses can be configured as point-to-point or as point-to-multipoint (TEI
Management setting in the configuration of the network interfaces).
Point-to-Multipoint Connection without a communication server
The basic access in point-to-multipoint configuration allows a selective dial-up of
the terminals connected in parallel using MSN, the Multiple Subscriber Number.
Here the network itself provides a kind of direct dialling, so to speak.
