Peripheral Boards
Connecting ISDN terminals (not for U.S.)
Depending on the system, you can set up a maximum of four internal S
0
buses (S
0
1 to S
0
4). A
maximum of eight ISDN terminals can be addressed on each S
0
bus.
The system does not assign the MSN until the S
0
port is configured on the “Euro bus”; the MSN
can be read out via administration.
When you set up an S
0
bus, it is assigned an MSN. This MSN is the first free station number in
the system. The S
0
station is immediately available under this MSN, without an outgoing sei-
zure.
Configuring an S
0
bus with a Mini-Western jack (not for U.S.)
S
0
telephones cannot be directly connected to an STLS board’s Mini-Western jack via the cable
supplied. You must first install a jack with cross-connected cables (see Figure 3-77).
>
If no MSN is entered in the terminal, a default MSN is automatically assigned after
you change the S
0
port to "Euro bus" in system administration.
