6.5.2.1
Basic parameters
Connection type
The type of connection depends on the equipment the gateway port is connected to. The
parameter must be the same for all interconnected pieces of equipment.
- Point-to-Multipoint is used to connect two to eight ISDN devices and it uses the MSN
service (Multiple Subscriber Number). This type of connection is used for telephones and
ISDN terminals.
- Point-to-Point is used to connect just two pieces of equipment and it uses the DDI
service (Direct Dialling In). This type of connection is used for PBXs, but cannot be used
for ISDN telephones and modems.
Note: For details on the ISDN line type see the registration sheet of your ISDN provider or contact your telephone
network administrator.
TEI Management
TEI (Terminal Equipment Identification) is an internal ISDN identification of connected
telephones.
- Auto must be used for the point-to-multipoint connection.
- 0 is used for the point-to-point connection. (Can be changed in exceptional cases.)
