1. G 711 ISDN D Channel protocols USA Master Slave configuration Appliance Documentation Introduction The Audio ISDN appliance M usicTAXI type VP 128 from DIALOG4 is designed for stationary use The MusicTAXI is compatible with ISO M PEG 11172 3 and supports bi directional Layer Ill and Layer Il The result is 2 x 15 kHz audio bandwidth using 2 B Channels This complies with the highest possible audio quality in conjunction with data reduction Moreover the MusicTAXI is compatible with the Philips 7 kHz telephone supporting the standard G 722 and framing according to H 221 The MusicTAXI can establish a connection to a PKI telephone and vice versa As soon as the device recognises that no MPEG data are being transmitted at an incoming call the G 722 standard is loaded into the DSP s automatically thus also establishing compatibility with the PKI telephone With the MusicTAXI a connection can be establish from and to nearly every analoque telephone even GSM Approx 20 different D Channel protocols are available for the MusicTAXI allowing a world wide use The protocols 1 TR6 and ETSI are already integrated before the device leaves the manufacturer These can be selected via the supervisor menu For the use of MusicTAXI at the American ISDN network the protocol National ISDN 1 is available The SPID numbers are supported from MusicTAXI The fact that irrespective of place configuration or baud rate a
