1st New Patton SmartNode DTA VoiP ISDN adapter
Model: SN-DTA/2BIS4V/EUI
Model SN-DTA from Patton saves tens of thousands of ISDN users when Telia and many other operators in Europe are now shutting down the ISDN network. On the one hand, it can function as a normal terminal adapter (NT) so that an ISDN telephone/fax/switchboard can be connected to a VoIP network, but also as a transparent extender of an ISDN line over IP between, for example, a switchboard and a subscriber.
Up to eight ISDN terminals
To S-DTA, you can connect a chain (ISDN BRI/S0) with up to eight terminals (with unique phone numbers) to each BRI port, which is also powered so that you don't have to use individual network adapters.
Supports the latest in traffic prioritization
For the highest speech quality, prioritization is required in the network. This is necessary so that real-time traffic such as e.g. speech, takes precedence. In SN-DTA you have 802.1p, TOS, Diffserv, 802.1Q with VLAN (insertion/deletion), which provides optimal conditions even in an already loaded network.
