The A series is an analogue hybrid key system that supports four sizes of modular CCU (pre-configured). System-specific handsets (analogue keyphones and two wire handsets) available in 6 key standard phones, 12 key standard, and 12 key executive display phones.
The SBS is an analogue hybrid key system, supporting analogue lines only, the user can utilise analogue keyphones or two wire handsets.
It is a modular system allowing expansion of incoming lines and extensions. Extra features such as trunk-to-trunk transfer on the SBS, and the ability to use the existing phones make the SBS an upgrade path from the A series. |
