The conversion of telephony to IP often involves purchasing a new ICT system. Although these modern systems are state-of-the-art and offer all sorts of modern features, you will not find a connection for the existing door phones anywhere. Here's the solution:
With the TSA-a/b door phone adapter, door terminals with an older 4-core interface or a 2-core connection in accordance with FTZ 123 D 12-0, which perhaps cannot be easily replaced for structural reasons, can be connected to the analogue port of a modern, VoIP-enabled ICT system. The existing door terminal, from Siedle, Ritto, Grothe or Auerswald/FONtevo for example, can be kept.
The TSA-a/b is suitable for use on all conventional ICT systems with analogue subscriber ports.
