Ascotel IntelliGate 2025/2045/2065
Part 4 Cabling interfaces 783
Example:
The address of a terminal with TSD 6 on S interface 0.12 on the 2025 / 2045
mainboard is: Trunk connection 0.12-6.
In some cases ISDN terminals do not log on to the PBX with a TSD. The system
automatically enters the first ISDN terminal to log on without an TSD as TSD 1 in
the numbering plan. Other ISDN terminals without a TSD cannot be operated on
the same S bus since TSD 1 has already been allocated. The other terminals on the
bus must log on with TSD 2...8 on the PBX.
PC Operator Console Office 1550
The V2 protocol must be set in the interface configuration.
2 PC Operator Consoles Office 1550 can be connected to an S bus in V2 mode.
