“ Elmeg CS290-U - ISDN telephone - light grey „
The price-performance ratio of the elmeg CS290 sets new standards for ISDN system telephones. With this model, ELMEG offers a price that is barely higher than that for an ISDN standard phone but with price-performance features and additional convenience functions that are professional grade.
The Up0 interface is increasingly prevailing as a cost-effective alternative with existing 2-wire phone lines, replacing the installation of ISDN 4-wire connections. Up0/S0 converters enable a fully digital ISDN connection with two basic channels over an existing 2-wire line. The combination elmeg CS290-U - direct Up0 connection without external converter is an especially elegant solution. And that's not all: the Up0/S0 module also offers an S0 output used by the elmeg CS290-U to connect additional standard ISDN terminal devices.
