Outbound calls

This school had severe outgoing call restrictions in that the majority of extensions were barred for calling other extensions (with only two exceptions) primarily so that staff members couldn't "gossip" to each other in teaching-time.

Brief
The client needs 2 extensions (headmaster & deputy headmaster) to have unrestricted O/G access on the 2 exchange lines. Incoming exchange calls on the 2 exchange lines ring at these two extensions. Incoming calls should be able to be transferred to any extension. A music-on-hold source should be provided. There are 12 classrooms and these two extensions need to be able to call any classroom. Single-button extension-calling would be an advantage. They also need to be able to do an "all extension" page and perhaps also have access to other pre-defined paging groups. Paging to an eternal paging amplifier may also be required.

The 12 classrooms are to be barred from making any outside calls and are also barred from calling each other (i.e. they are able to call only the headmaster and the deputy headmaster). They can receive calls (either initiated from or transferred by) the headmaster or the deputy headmaster.

Telephones
The headmaster and deputy headmaster should have 20-key display telephones. Amongst other advantages, this gives them a visual indication of which classroom is calling and provides one-touch calling of classroom extensions. The 12 classrooms have non-display telephones fitted.

Programming considerations
The headmaster and deputy headmaster are placed into tenant group 1. All the classrooms are placed into tenant group 2. The exchange lines are placed into tenant group 1.

Cross-tenant-calling is allowed from T1 to T1 and also from T1 to T2. Extensions in T2 can call T1 but cannot call T2. This fulfils all the calling requirements of the customer’s brief.

All the classroom extensions have the function key disabled in programming. Two feature keys are programmed as DSS keys for the headmaster and the deputy headmaster. The other 7 feature keys could be programmed for either function codes or other system resources (paging, BGM etc) as required.

The headmaster and the deputy headmaster have exchange lines assigned to two feature keys. Twelve more feature keys are programmed as DSS keys for the 12 classrooms. Other feature keys are used as required for paging-group(s) and for external paging. Any "spare" feature keys can be used for functions, abbreviated numbers or resources as required.

The "0" and "9" codes normally used for calling the attendant or obtaining an exchange line are programmed as "null".
