    General flags
 
General flags is used to define DISA options for ISDN lines.
To access the dialog box, double-click in the TrunksParam column in the tab and select the General flags tab.

10.4.5.1  
Area: Trunk, previous trunk, next trunk 
This box shows the trunk code, card, slot number, and physical port of the selected trunk. The individual slots/ports can be selected using the Next trunk and Previous trunk buttons.

10.4.5.2  
Area: DISA day/night, None, Only night, Only day, Day and night 
In the DISA day/night field, code receiver (CR) parameters can be configure for each line. There are four options for DISA day/night service. You can allow full external access to telephone features (such as voice mail and call forwarding) only when night service is active, only when day service is active, or at both times. If you select none, the DISA function will be deactivated.
One of the following options can be selected:
   -   None, line always has CR turned on
   -   Only night, line has CR connected only during the day
   -   Only day, line has CR connected only during the night
   -   Day and night, line without CR connection
To make sure the DISA settings are complete, you must also set the DISA DID number in the Daylight saving time/DISA. You must also active the Station view: FlagsDISA class of service flag under .
If DISA has been configured for an MSI line, this line can no longer be used for call management.
No DISA flag may be set for MSI lines with DTMF DID since otherwise the DTMF is stopped for this line. In this case, the DISA handling is completed in the same manner as the direct inward dialing on ISDN lines.

10.4.5.3  
Area: Circuit flags, Call prio./immed. tone call wait. 
By setting this flag (Call prio./immed. tone call wait), calls on this trunk are signaled to partners as having a higher priority. The priority is set to be the same as the priority of external calls. In other words, calls via a prioritized line are thus queued before existing internal calls, but after existing external calls. Note that existing first calls (not waiting calls) are usually never displaced, regardless of their ring type.
With call waiting, the caller always receives a ring tone immediately regardless of whether or not this flag is set.

10.4.5.4  
Area: CMI Flags, Echo Canceller, Echo Suppressor, Artificial Echo 
The CMI Flags (see also Settings | Cordless (Not in the USA)) determine the echo behavior for all mobile stations within the communication system that are phoning via this trunk.
Note that when using the trunk as a CMI extension connection or with mobile phones at an SLC, the line-specific echo parameters do not take effect.
The settings are made by the system depending on the line type used.
Exception: for 4-wire analog dedicated lines, the Echo Canceller must be manually set to OFF.
Should problems nonetheless occur, the behavior can be changed by switching it manually.
The default settings are as follows:

Connection to the CMI station via:  
Artificial Echo  
Echo suppressor  
Echo Canceller

The system cannot automatically differentiate between 2 and 4-wire TIE trunks. Consequently, in the case of an analog 2-wire TIE trunk hardware configuration, the Echo Canceller flag must be reset manually.
