I. general

MS26 system offers the users many facilities. While using these facilities erroneous operations may take place and this may cause problems for the users. Therefore, the software structure of the system must be known in detail so that the reasons of the errors that the users face can be found and solved.

This section is to give information about the most common software problems faced in MS26 system operation and the methods that can be used to overcome these problems.

Iı. software troubleshooting

CALLING AN EXTENSION:

a)    If another extension is ringing instead of the called extension, the called extension might have activated Follow Me.

b)    If the called extension is ringing only once, then he may have activated Do Not Disturb.

MAKING EXTERNAL CALLS:

a)    If the extension receives error tone upon trying to access a line:

The extension may not have sufficient External Call Authority.

Night Mode may have been activated and Night Mode External Call Authority of the extension may not be sufficient.

The line that the extension wants to access or all the lines may be Out Of Service.

The extension is not allowed to access the line that he is trying to.

The extension might have locked his telephone.

When the extension wants to activate Calling From Common Pool or Calling From Private Pool facilities, there may be no numbers stored in that pool or that pool may contain a number which is beyond the extension's External Call Authority.

There may be Call Prefix Restriction for the dialed number.

b)    If the external calls of a specific extension are suddenly cut, Outgoing Call Time-Out may have been defined for this extension.

AUTO-DIAL:

a)    If the extension receives error tone upon trying to activate Last Number Auto-Dial:

Another extension has activated Auto-Dial before this extension. In this case, the extension should wait until the other extension terminates Last Number Auto-Dial.

CAMP ON

If the extensions try to make external calls by Automatic Line Access, they cannot camp on the busy line.

CALL HOLD:

If an extension cannot put his calls on hold, then the authority to use either hook switch or "#" key to make Hook-Flash might not have been given to the extension.

LINE-LINE CONNECTION:

After the connection is established:

a)       The party who wants to continue the connection should be using a DTMF telephone set to be able to dial "9".

b)       If one of the parties hangs up within the first 45 seconds, the lines are released after the first 45 seconds, however if they hang up after the first minute then the lines are released immediately.

PASSWORD DEFINE / UPDATE & PHONE LOCK:

a)       The password should be between 001-999.

b)       The extension receives error tone if he enters a wrong password to cancel and update his password. After the third entry of a wrong password, he is prohibited to make further trials until the start of the next hour.

c)       The extension receives error tone upon trying to lock his telephone if he has not defined a password yet.

REMINDER SERVICE:

a)       If the extension is busy at the reminder time, then the extension rings at the next minute after his telephone gets idle.

b)       If the telephone does not ring at the reminder time, the extension may be failing to enter the code in the required format.

BACKGROUND MUSIC:

The extension receives error tone if the Music On Hold is not activated by the operator.

TIME & DATE SETTING:

If time or date is not changed after the operator uses Time & Date Setting, he may be failing to enter the codes in the required format.

EXTERNAL CALL DIVERSION:

a)    If External Call Diversions are not functioning, the system may be in day mode. Put the system in Night Mode to activate this facility.

b)    If one of the parties hangs up within the first 45 seconds, the lines are released after the first 45 seconds, however if they hang up after the first minute then the lines are released immediately.

If certain types of external calls (e.g. long distance or local) or no external calls can be received from the output device, the CRL Report Level might have not been chosen correctly by CRL Report Level (877 coded) program.
