ISDN SubAddress
using a sub address enables you to connect up to eight ISDN terminals to the same ISDN
telephone number and line. the terminals are addressed by using different sub addresses. to
call a terminal with a sub address, separate the ISDN telephone number and the sub address
with a * (asterisk). Note that this service has limited access on some ISDN networks.
Value space:
<S: 0, 20>
Format:
String with a maximum of 20 characters.
ISDN SubAddressSend
using a sub address enables you to connect up to eight ISDN terminals to the same ISDN
telephone number and line. the terminals are addressed by using different sub addresses. to
call a terminal with a sub address, separate the ISDN telephone number and the sub address
with a * (asterisk). Note that this service has limited access on some ISDN networks.
Value space:
<Off/On>

ISDN BRI Alert
Select if the system should respond with an alert message to all incoming setup messages, or
to the first incoming channel only.
Value space:
<Off/On>
Off:
When set to off (default) the system will respond with an alert message only to the
incoming setup message related to the initial channel. Note that if the PBX requires this
signalling you will only get connected on the first incoming channel.
On:
When set to on, the system will respond with an alert message to all incoming setup
messages.
ISDN BRI AutoActivation
Set the auto activation mode of the BRI interface (ISDN Layer 1).
Set AutoActivation to off when connecting ISDN Link BRI lines to equipment that enforces
deactivation of BRI lines that are not in use (power saving). this ensures that the ISDN Link
does not keep trying to reactivate the BRI lines when they are unused. the BRI lines will be
activated when making an outgoing call.
the ISDN Link will not report any layer 1 faults when AutoActivation is off, since it cannot
distinguish between a layer 1 fault caused by link deactivation of the attached equipment, and a
real layer 1 fault.
If AutoActivation is not set to off, and attached equipment enforces BRI deactivation, one may
experience cyclic BRI errors, and not being able to make outgoing calls when those cyclic
errors are active.
Value space:
<Off/Selected/All>
Off:
When set to off, no interfaces will be activated.
Selected:
When set to Selected, the system will activate the interfaces which are already on.
All:
When set to All, the system will activate all interfaces regardless of status.
ISDN BRI ChanId
Select if BRI Channel ID information should be sent to the PXB.
Value space:
<Off/On>
Off:
When set to off, Channel ID information is not sent. Default setting is off.
On:
When set to on, the system will signal to the PBX which BRI channels is used for the call.
Note: this setting must be set to on, to work with an ericsson MD110 PBX.
ISDN BRI InterfaceSearch
Selects whether to start searching for available B-channels from the highest numbered
interface or from the lowest numbered interface.
Value space:
<High/Low>
High:
When set to High, the system will start searching for available B-channels from the
highest numbered interface.
Low:
When set to Low, the system will start searching for available B-channels from the
lowest numbered interface.
