British Telecom (BT) Octara Keysystem
The British Telecom Octara is a medium size keysystem designed for busy offices such as accountants, solicitors, travel agents, doctors' surgeries etc.
Initially equipped for 2 lines 6 extensions it expands using additional 2 x 6 cards up to the last card which is a 2 x 8. This gives a maximum configuration of 10 lines 32 extensions. The BT Octara system supports analogue lines only.
The BT Octara only supports its own terminal telephones TX21, TX23 and TX25 and cannot handle standard telephones such as cordless, fax machines etc. The system is analogue lines only and will not support ISDN. You can connect an answering machine via a switch 2A which diverts the incoming line before it gets to the system. External paging port connects into most public address systems. Music on hold port connects a music source.
There are still many British Telecom Octara systems around still working well. We have stocks of all BT Octara parts including CCUs, telephones and expansion cards.

Dennis's Trade Tip: If you are about to install or expand an BT Octara system remember that the extensions connect using a left hand socket 2/3C or 3/3C. Make sure the electrical supply is nice and clean or better still use a mains filter. British Telecom Octaras do not enjoy power surges or spikes so don't plug it in next to the customer's MIG welder!
