Installing and operating the IPBS and IPBL
Configuring trunks
Trunks cannot be configured (configuration sets will be greyed out) in the IPBS/IPBL when
Provisioning is used with IPO PBX. However, it will still be possible to activate a primary trunk
manually (see Activation of Primary Trunks on page 83). About Provisioning, see 4.1.6
Provisioning on page 37.
A shared trunk is used for connection between the IP-DECT system and an PBX which can be
an ACM PBX or an IPO PBX.
There are two kinds of trunks; primary and redundant. One or more primary trunks can be
configured. They are used in the first place. One or more redundant trunks can also be
configured. They are only used if none of the primary trunks are in "Active" mode. That is, all
primary trunks must be in "Down" mode.
Note:
Only one primary and one redundant trunk can be configured for the IPO PBX.
Note:
To configure primary and redundant trunks, do as follows:
1. Select DECT > Trunks.
2. To determine the status of the trunks towards the IP-PBX, enter in the Period (sec) field
how often the IPBS/IPBL shall send status inquiry messages to the IP-PBX.
3. Enter the IP Address of the IP-PBX in the CS IP Address field and the port of the IP-PBX in
the CS Port field.
4. Enter port address of the IPBS in the Local Port field.
5. If a redundant trunk shall be configured for connection to the IPO PBX, make sure that the
PBX Resiliency check box has been selected (DECT > Master).
6. Note: The PBX Resiliency check box will be disabled (greyed out) when Provisioning is
enabled in the IPBS/IPBL. About Provisioning, see 4.1.6 Provisioning on page 37.
