VERSATILE KEYSYSTEM FOR BUSINESS COMMUNICATIONS
GPT Masterline systems offer a cost-effective way for modem businesses to
provide efficient communications throughout all levels of an organisation.
Masterline is available in three system sizes which range from eight to 24
trunk lines with up to 64 telephone users.
- MASTERLINE 816 - 8 trunks and 16 extensions
- MASTERLINE 1236 - 12 trunks and 36 extensions
- MASTERLINE 2464 - 24 trunks and 64 extensions
The systems employ common hardware technology which allows for simple
upgrading and also for the compatibility of instruments across the size range.
Wide Choice of Instruments
Each size offers the choice of executive standard and basic keystations. They
are of a pleasing, modem design which enhances the image of any office
environment, and are extremely simple to use. Dual red and green LEDs allow the
status of all trunk lines to be monitored at a glance. There is also the option
of approved loop dialling ordinary telephones to give cost-effective
communications in areas not requiring keystation features.
- Handsfree Operation: enables the user to make or answer calls without
lifting the handset.
- Abbreviated Dialling: each station can access up to 90 system
abbreviated dial numbers and store up to 10 personal numbers for single
- Do-not-disturb: permits managers to work without interruption.
- Manager/Secretary Link: allows one or more managers to forward calls to
- Office Paging: The integral paging system allows staff to be located
quickly to answer incoming calls or for immediate conversation with
- Complete Flexibility in the allocation of incoming call ringing in both
the day and night service modes.
Many of the features are allocated to specific telephones through system
programming and this enables the tailoring of specific facility packages for
individual staff members so as to best meet their functional requirements.
Masterline enables management to control the operating costs of the system. Six
levels of outside call restriction can be applied to
individual extensions which, together with the call logging facility; cuts
costs, inhibits call abuse and allows for the charging of calls on a
departmental or client account basis.
Hybrid PABX Operation
As well as operating in the traditional key system mode GPT Masterline can also
function as a hybrid PABX through the provision of up to two Direct Station
Select (D.S.S.) Consoles at nominated operator positions.
In addition to being used as a stand-alone system, Masterline can also be
connected to a PABX in order to give "behind PABX working" This provides a
department or specific group of employees with their own sub-communication
system, whilst still allowing them access to all the PABX features.
