Model SN-DTA from Patton saves tens of thousands of ISDN users when Telia and many other operators in Europe now turn off the ISDN network. On the one hand, it can function as a standard terminal adapter (NT) so that an ISDN telephone / fax / telephone exchange can be connected to a VoIP network, but also as a transparent extension of an ISDN line over IP between, for example, an exchange 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 telephone numbers) to each BRI port, which is also powered to avoid individual mains adapters.
Supports the latest in traffic prioritization
For the highest speech quality, priority is required in the network. This is necessary for real-time traffic such as 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.
