Program 10-03-06 = 0 (Extended Passive Bus) - assigned when the distance to the last
device is up to 500m. Up to 3 devices may be connected up to 50m apart.
Program 10-03-06 = 1 (Short Passive Bus) - assigned when the distance to the last
device is less than 200m. Up to 6 devices may be connected.
6. Program 10-03-07 can be used to add digits to the end of the extension number to increase
the size of the indial number range. If Program 10-03-07 = 0, the indial number to the S-Bus
ports are the logical port extension numbers, e.g. 208 and 209. If Program 10-03-07 = 1, the
indial number to the S-Bus ports will be, for example, 208X and 209X.
7. Program 10-03-14 (Service Protocol for S-point) should be left at default (0 = Keypad facil-
ity).
8. Determine the type of outgoing trunk the S-Bus device will select when it goes off-hook and
dials the trunk access code (e.g. 0).
ISDN Trunks Only:Program 20-25-20 = OFF
ISDN or PSTN Trunks:Program 20-25-20 = ON
9. Incoming calls to the S-Bus device can be assigned like any other extension, e.g. intercom
calls, trunk calls, direct in-dial.
Notes:
•
Line Key appearance for ISDN interfaces set as S-Point is disabled.
•
The ISDN interface set as S-Point will be assigned the next available
extension numbers, e.g. in a basic default system, the S-Bus extensions
numbers will be 208 & 209.
•
When the S-Bus lines are selected internal dial tone is provided. At this
point all internal topaz extension numbers can be dialled or a trunk
access code.
•
Note that the BRI interface must be assigned as point-to-multipoint
(default setting) when multiple devices are connected (Program 10-03-
03 = 0).

Caller ID
With Caller ID enabled, the system will provide information for ISDN calls that do
not contain the Caller ID information. Outgoing calls on ISDN trunks can send
extension based caller ID details with the call.

This feature requires ISDN trunks, or loop start trunks with disconnect supervi-
sion. Off-Premise Call Forward for Doorphones can be transferred to the external
party through ISDN lines only.
•

This feature only works on analogue trunk. ISDN trunks do not have the Forced
Trunk Disconnect available.
