RAD Data comm Vmux-2100 Applications, Transmitting Compressed Voice and Signaling over IP Network

Chapter 1 Introduction Vmux-2100Installation and Operation Manual

Applications

Figure 1-1shows a Vmux-2100 application, where the gateway transmits compressed voice over an IP network, including transparent transmission of CCS and CAS signaling.
