8.27 Configuring an Internal S0 Bus with Multiple Stations (Not for U.S.)

Each S0 bus can support up to eight terminals or telephones. For this purpose, one or more system ports must be configured as a Euro-bus.
In the U.S., S0 busses are internal only. Refer to Section 8.13, Configuring an ISDN Multi-Device Connection With Multiple Subscriber Numbers (for U.S. Only), on page 8-35 for configuration information.

Note
Note the following when starting up an internal S0 bus:
 |
A total of 64 MSNs can log onto each bus. They must be intered in the internal CDB numbering plan and should not be in used by another other telephones (such as optiset E). Sixty-three MSNs can occupy any position in the KDB. If you are starting up 64 MSNs, one must be the default MSN for this S0 port.
S0 Port |
Default MSN |
1 |
Internal station number of the last station position |
2 |
Internal station number of the next-to-the-last station position. |
... |
... |
|
 |
If you need more than 64 MSNs, add another S0 bus.Then proceed just as you would for configuring the first S0 bus. |
 |
You must assign MSN numbers to each terminal or telephone on the Euro-bus. |
 |
If you do not assign an MSN to the telephones, the default for this port will be used as the MSN for all telephones. In other words, a call placed to this default MSN will also be placed to all telephones connected to the bus. |
 |
The MSN setting on the telephone depends on the telephone. |
