ECHNICAL DATA
CHAPTER 7 ANNEX
• Loop current detection
• Call charge receive 12 or 16 kHz (frequency and level setting country-specific)
• CLIP detection in accordance with ETS 300 778-1
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
• Maximum of 2 simultaneous call connections
Analogue terminal interface FXS
• Configurable multifunctional interface for connecting analogue terminals and equipment.
• The following applies for the FXS mode Phone / Fax, two-wire door and general bell:
– Voice path with A/D and D/A conversion (standard PCM, A-law)
– Transmission as per ES 201 168 (level country-specific)
– Constant-current loop supply approx. 25 mA (with loop resistance £ 1000 W)
– Receive pulse or DTMF dialling
– CLIP display on 2 analogue terminals interfaces simultaneously.
– Ringing supply 40…43 V 50 Hz at load 4kW; no DC voltage overlay (country-specific versions
also with 25 Hz)
– No control key detection
– No charge signalling pulses
• For more technical details and cable requirements see Multifunctional FXS interfaces.
