There are four groupsavailable and the access codes are 50–53.If the station has an IN/OUT (or IG) key assigned to it:1. Press the IN/OUT key. It will light red when the station is in the group.2. Press the IN/OUT key again. The light is off when the station is out of thegroup.If the station does not have an IN/OUT (or IG) key:1. Lift the handset and dial 53.2. Dial the group number.3. Dial 0 to leave the group—OR—dial 1 to enter the group.4. Receive confirmation tone and hang up.Note: A station can be in more than one group.

See Program Station Key Assignments in the “System AdministratorProgramming” section.Operator GroupTo create a backup or relief operator (‘attendant position’), assign the main operatorand one or more backup individuals to the operator group. All but the main operatorshould be out of the group. When it is necessary to use a backup operator, put the de-sired backup station in the group and remove the main operator. When incoming calltraffic is heavy, you can have another station put itself in the operator group along withthe main operator to handle the extra call load.Note: Refer to MMCs 600 and 601 for assigning station and operator groups.Direct Inward System Access (DISA)From outside the office, selected individuals can call into the system on special DISAline(s). A security code must be entered to gain access.

To use DISA:1. Call in on a DISA line from any phone with tone dialling.2. When you hear the DISA dial tone, dial your security code (the extension num-ber plus your station passcode).3. If you are allowed access, you will receive system dial tone.4. Dial a line access code, receive outside dial tone and then dial a telephonenumber
