The D102B is a device that fulfils both the function of a cordless telephone and a wireless doorphone.
The COMWEI wireless doorphone system allows to receive phone calls and calls from the doorphone in parallel. A digital radio channel in the DECT band was used for the two-way communication between the handset and the external panel, and between the handset and the telephone base.
If more than one handset is used in the system, it is enough to connect only the main base to the telephone network, so that all the handsets will gain the functionality of the phone.
