Assigning DNs to the S- loop
You can have a maximum of 58 ISDN DNs on your system. However, there are only 28 default
DNs provided. The default ISDN DN range is 597 to 694. To add to the defaults, you need to use
DNs from the Companion range: 565 to 597 (change DN type to
ISDN and DECT )
Companion: If you have either a legacy Companion wireless system, which uses the
Companion DNs, or a legacy DECT portable system, which uses the ISDN and DECT DNs,
ensure you do not overwrite any DNs assigned to the handsets for these systems.
To assign device DNs to the loop DN (maximum of eight devices per loop):
1
Choose Services , Telephony Services , Loops.
2 Click the key beside the loop number (for example, Loop 201) where you want to assign DNs,
and beside the DNs on loop heading.
3 Click the Loop DN heading.
4
At the top of the navigation tree, click on the Add button.
5 In the Add DNs dialog, enter an ISDN DN.
Figure 78 Adding a DN to the Loop DN group
6
Click Save to add the DN.
7 Repeat steps 4 to 6 for all the DNs you want to add to the loop.
8
Click the DNs on loop heading.
9 In the Loop DN field, enter an ISDN DN that you assigned to the Assigned DNs group in the
previous procedure. This telephone acts in a similar way that a Prime telephone works.
Incoming calls that are not answered go to this device. Also, if the other devices on the loop do
not have specified DNs, calls coming into the Loop DN ring at all these devices.
• If you leave None in the field, unanswered calls will be dropped.
• If the field is left blank, none of the Assigned DNs will be able to make or receive data
calls.
