Installation and Operation Manual

IP-DECT Base Station & IP-DECT Gateway (software version 3.0.x)

buildings. If two Masters are configured within the same coverage area two different sync

systems will be created instead of one. This will make handover and roaming between the

systems impossible. As a consequense the air sync slaves will loose synchronization

frequently.

Configure Air Sync mode:

1 Select DECT > Air Sync.

2 Select in the Sync mode drop-down list:

• Master, if this IPBS is the Air Sync Master.

• Backup Master, if this IPBS is the Air Sync Backup Master.

• Slave, if this IPBS is an Air Sync Slave.

3 Click "OK".

Enable LED Indication of Air Sync

LED indication of air sync quality is enabled by selecting the LED Indication check box. This

indication is used to indicate the air sync quality when planning or troubleshooting the

system, see Verify the Air Sync Coverage on page 76.

Verify the Air Sync Coverage

1 Configure an IPBS to be air sync slave, to synchronize to the Base Station in the site

survey tool (SST). Different B-ARIs can be assigned to the SST. Depending on the B-

ARI different sync RFPIs has the be used in the IPBS.

2Assign SARI, see 8.5.24 SARI on page 75.

3 Assign a static IP address, see 8.2.2 Set a Static IP Address on page 57.

4 Enable Master. The Radio is using the local Master.

5 Enable LED indication of the air sync, see Enable LED Indication of Air Sync on page

76.

6 Power the IPBS using a battery pack.

7 Move the SST to the planed location of the Sync Master. Move the IPBS to the

planned IPBS locations with air sync hop 1 and check the upper LED (LED2, see also

LEDs on page 4). The upper LED should be off or green, if it is fixed amber or

flashing amber, the air synchronization is inadequate.

8 Move the SST to a location with air sync hop 1 and verify that the IPBS has good air

sync coverage at IPBS locations with air sync hop 2.

Repeat step 8 for all air sync hops needed.
