Plan the CS context

The configuration described above implies the following configuration:
• It is very important to specify from where to get the clock source for the packaging of the ISDN voice
frames. In our example we are connected to the PSTN network and get the clock source from the ISDN
over the ISDN port 2/3.
• We synchronize the time of the SmartNode to the ISDN time. (Refer to section
tings" on page 280). To get useful system event logs it is very recommended to set the system time!
• We need four ISDN ports, two for the PSTN and another two for the PBX. (Refer to section
ISDN ports" on page 283)
• Furthermore we need two PSTN interfaces. On each we bind two ISDN ports, which means, that we create
a line hunt group on every PSTN interface. (Refer to section
• For every remote H.323 device we need a H.323 interface. There are two in total. One gets the remote IP
address of the SmartNode in office A, the other the IP address of the SmartNode in office B. (Refer to sec-
tion "Configure call routing"
• We need a Session Router routing table to route the calls depending on the called party number. (Refer to
section "Configure call routing"
