FIG. 2 FUNCTIONAL ELEMENTS RTS SIP-ISDN
2.1 Functionality
The RTS SIP-ISDN System incorporates an ISDN telephone interface and a LAN inter-
face. The complete signal processing is taken over by a digital signal processors. In this
way the following functions are realised:
DSP1:
– G.711 Audio encoding and decoding
– G.722 Audio encoding and decoding
– Signalising management
– Control of the complete system (Keypad, display, relays, TTL, RS232)
Via the Audio channels 1 & 2 the Audio signal is inserted or output analogue or digitally.
If the digital AES/EBU Audio interface is used, two separate Sample Rate Converters are
available for automatic clock synchronisation. For external clocking a clock input and a
clock output are available
The configuration and operation can be primarily carried out via the front keypad and the
illuminated display .
Configuration and control is especially comfortable with the RTS SIP-ISDN Windows
PC Software which is included in delivery and which communicates with the system via
the RS232 or LAN interface.
