9. Appliance Documentation Introduction The Audio ISDN appliance MT REP is designed for mobile live use The unit is built into a PUR FOAM case with impact resistant frame to avoid mechanical damage All connectors and controls are recess mounted The MT REP is compatible with ISO M PEG 11172 3 and supports bi directional Layer Ill The result is 1 x 15 kHz audio bandwidth using 1 or 2 B Channels This complies with the highest possible audio quality in conjunction with data reduction and corresponds with the ITU recommendation for comment lines Moreover the MT REP is compatible with the Philips 7 kHz telephone supporting the standard G 722 and framing according to H 221 The MT REP 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 automatically into the DSPs thus also establishing compatibility with the PKI telephone Approx 20 different D Channel protocols are available for the MT REP allowing world wide application The protocols 1TR6 and ETSI are already integrated before the device leaves the manufacturer These can be selected via the supervisor menu The fact that a connection via ISDN can be established fully automatically from just about anywhere in the world irrespective of place configuration or baud rate is absolutely unique The dialed appliance is always configured by the calle
