Network Planning
The following describes the procedure for checking your network and planning
the type of communications between AIP and the IP terminals.
Note:
– Please note that the expertise of an experienced network engineer is
crucial for assessing and optimising the network environment.
– We strongly recommend that you examine the network using a special
check-list, which you can download from our support page (asco-
tel.ascom.ch). Our specialists will be happy to assist you on the basis
of the completed check-list.
1. Check whether your network environment complies with our recommenda-
tions ("Bandwidth Management", page 41); if not, please take the necessary
measures to comply with the requirements.
2. Determine the prioritisation method in accordance with the Chapter "Priori-
tising", page 42.
With regard to initialisation values ToS is activated and CoS deactivated
(TOS is recommended if the voice connection is to be set up via a WAN link.
CoS prioritises voice traffic at the level of the switches).
3. Plan the bandwidth control in accordance with the Chapter "Bandwidth
Management", page 41.
