Figure 2: Example of an MX-ONE exchange with a main site and
remote sites which, from the synchronization point of view,
are independent from each other. Synchronization between
the gateways within each site is distributed by
synchronization ring. Each site is synchronized by a free
running MGU index 2. This must be used when a customer
site only has SIP routes.
Note: When moving between the different sites, the PP will lose connec-
tion and drop any ongoing calls. Power off and power on the PP
is recommended to avoid 'No System' in the display.
If a PP is not powered off before leaving a site the portable will loose
contact with the system (the display will show No system). Once the
portable has reached a coverage area again (remote site) the portable
will regain contact with the system, and a location registration will be
made.
