8.10.1.5 Interactions
Interactions with other features
IBS DECT and IBS PWT (Personal Wireless Telecommunications) cannot run together on the same
system. The first IBS plugged determines the system type (DECT or PWT).
To switch from one system to another, unplug all IBSs, make a warm restart and plug in the IBSs.
Interactions with other applications
IBSs are fully compatible with other wireless technologies such as VOWLAN.
Interactions with other software releases
OXO Connect release 5.1 requires 4 kinds of DECT initialization: Europe, Latin America, United-States
and China. See also:
8.10.1.6 Limits
Number of IBSs: 20 IBSs per cabinet is recommended, however, the number of IBSs is only restricted
by the available power.
DECT link limit: 3 links on an IBS with one UA access, 6 links on an IBS with 2 UA accesses.
DECT handset limit: up to 120 handsets on a system.
8.10.1.7 Performance and quality
IBSs are downloaded during the system start phase or when hot plugged. A system with many IBSs
plugged might take longer to complete the start phase.
Downloading 1 IBS takes about 30 seconds. It takes more time when several IBSs are plugged on the
same UA resource.
The end of restart is only possible after all the devices have been taken into account.
If an IBS downloading fails, the IBS restarts with the previously installed software.
