Description

Fully duplex audio codec with ISDN and Ethernet 10/100-Base T-connection for remote control and the possibility to distribute audio over networks such as Intranet, ATM, etc. TCP for point-to-point and point-to- multipoint connections, UDP for Broadcast and Multicast modes. Additionally, an X.21 or V.35 interface as well as optionally up to three ISDN interfaces or mixed with POTS interfaces. Configuration and operation directly with the keypad.
