7.4.2 Terminal interfaces
The following technical data applies to the terminal interfaces:
Digital terminal interface DSI
• Proprietary interface, two-wire
• Two system phones of the MiVoice 5300 series can be connected per interface (AD2 protocol)
• One SB-4+/SB-8 radio unit can be connected (with 8 channels the SB-8 radio units requires two DSI
interfaces)
• Power supply min. 75 mA, limiting at approx. 80 mA, terminal voltage 36…48 V
• Line termination in the phone
• Transparent transmission of 2 PCM channels
Digital terminal interface BRI-S
• Standard Euro ISDN interface
• Phantom power supply min. 140 mA, limiting at approx. 170 mA, terminal voltage 36…41 V
• Up to 8 terminals can be connected
