General

Here you will find the overarching settings for exchange connections.

Table 1. Settings for auto completion of exchange access code for MiCollab, BluStar, Mitel One, and Dialer applications
Parameter	Explanation
Activate auto completion	Enables auto completion of exchange code. This feature is available for MiCollab, BluStar, Mitel One and Dialer applications.
Apply exchange prefix if dialling number has equal or more digits	Exchange prefix is added if the dialed number is equal to or more than the number specified in this field.

Table 2. Settings for exchange-to-exchange connections
Parameter	Explanation
Exchange-to-exchange connection	This setting lets you restrict or bar exchange-to-exchange traffic throughout the system: Not enabled: No exchange-to-exchange connections can be set up. Digital-digital only: For an exchange-to-exchange connection to be set up, both network interfaces must be digital. Digital-analogue also: For an exchange-to-exchange connection to be set up, at least one network interface must be digital. Analogue-analogue also: An exchange-to-exchange connection is always possible.
Disconnect timeout (min)	Only for call type Also analogue-analogue: The connection is cleared down after the set disconnect timeout.
Wait for connection	Lets you specify whether a configured Call Forwarding Unconditional to the exchange in the case of an external call is always switched through or only if the caller takes the call and sets up a connection as a result: The call forwarding unconditional is switched through only if a connection is set up. If the destination user is busy or unobtainable, this setting ensures that the caller does not incur charges for the connection up to the communication server. The call forwarding unconditional is always switched through.

Clock reference and clock reference table

The clock frequency of a communication server is provided (synchronized) by the public network via the basic accesses BRI-T and the primary rate accesses PRI. Should synchronization by the public network fail (due for example to exchange line interruptions), the communication server will use its own clock. The default settings made automatically are sufficient in almost all cases. Only change the settings if you have a special configuration that requires a change (e.g. for private networking or for CAS/R2).
