ISDN protocol configuration
1
Open the Configuration menu via the Function
menu > Advanced functions menu.
2
Double-clicking the ISDN configuration displays the
ISDN configurations implemented in NWC Voyager.
Switch to owner level to edit the entries:
•
Protocol
Select Euro ISDN for connection of equipment
conforming to the European ISDN standard.
Select NI-1 protocol for equipment conforming to
the NI-1 standard (National ISDN-1).
•
Date/time element
When enabled, date and time is sent to the connected
Terminal Equipment during call establishment. Some
ISDN devices do not survive this message. The date
and time transmission may then be disabled.
•
Layer 2 Activation
The layer 2 connection is deactivated after some
idle time as default. Some ISDN devices interpret
this as an alarm situation. Layer 2 dectivation can
then be disabled. When the ISDN protocol is set to
NI-1, this option is on as default.
•
Default service
Some ISDN devices can not signal their own MSN
number. Such a phone will be not able to use the
64 kbps service since all "unknown" speech devices
are required to use the 4.8 speech service. The
user can set NWC Voyager to map all "unknown"
devices to 4.8 speech (AMBE) service.
NB! Remember to revert to user level.
