PBX Networking Technical Details

Technical Details
A different PBX number must be set for each OpenCom 100 in a PBX network. This setting can be found in the Web console, in the menu PBX Configuration:
System: Settings under the heading System linking. You can also set the maximum value for the transit counter there. This value depends on the topology of the PBX network and should allow the system to have the maximum number of further connections possible.
You can display the connection status of the lines at any time in the Configurator menu System info: PBX: Trunks. You should check this in particular after making changes to a configuration to see whether all the lines used for system networking are operable.
Some of the features possible in Q.SIG are not supported by OpenCom 100 with all their options, for example callback on busy within the Q.SIG network. The call categories defined in Q.SIG (e.g. Emergency Call, Operator, Normal) and the Q.SIG name transmission feature (“user names”) are fully supported.
The code digits to be used for seizing a route with open numbering are not transmitted to the destination PBX and thus cannot be evaluated by it. To reseize a route (for example for a callback), you must set the appropriate digit prefixes in the trunk group configuration for the routes to be reseized.
Tip: If, for example, you are configuring a route which can be seized using routing code “5” and have selected one or more bundles for this route, change the Prefix for dest. call num-
ber at incoming internal setting to “5” for this bundle in order to enable the route to be reseized.
Owing to their hardware properties, not all S
0
ports of the OpenCom 100 can be used for PBX networking without restrictions. Depending on the type of system,
