Digital Telephone Sets


System telephones from the optiset E family can be connected to all servers of the Hicom 150 series. 

They are designed to give quick and easy access to the many Hicom features and they can be easily adapted to the requirements of individual workstations. Features you need a lot can be assigned to feature keys. LEDs can give you an idea of activated features or busy lines. And additional terminals (e.g. PC, fax machines, telephones, headsets) can be easily connected directly at the workstation by simply plugging in different adapters from the underside of the telephone.

Thanks to interactive user guidance and acknowledged superior functionality, these system telephones offer significantly more than conventional telephones. And they even look good. They are available in the colours warm grey and black.

Accessories & Special Applications


Have you notice the really big display of the optiset memory set? That's your Operator. It has a build-in Alpha keypad with integrated notebook function. You can type in easily names, phone number and addresses. And voila, here you have your directory, right at your fingertip. Search for names by using the initial letter, or just browse through your list, as you would do it on your mobile phone directory.

And if you want to have some more features at a touch of a key, you can connect up to 4 Optiset Key Modules, each gives you 16 more feature keys with LEDs. But maybe you would prefer to know, which lines and telephones are busy right now? Then the Siemens Hicom Attendant BLP Busy Lamp Panel would be your first choice. There you have 90 additional feature keys and LEDs.

And the Optiset IP adapter connects to a LAN network

Flexible Adapter System

Talking about LAN. The new Siemens product HiPath comes as a module which can be easily integrated into your Hicom 150 PABX, starting from version H. HiPath uses the Hicom system's LCR function for voice, fax and data communication. No external routers, no additional servers or ISDN PC cards are required for the LAN PCs, because router functionality, firewall functions and security protocols are already integrated.
