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 equip-
ment.
• The following applies for the FXS mode Phone / Fax, two-wire door and general
bell:

– Receive pulse or DTMF dialling
– CLIP display on all analogue terminal interfaces (Mitel 415/430 only on 2 ana-
logue terminals simultaneously).
– Ringing supply 40…43 V 50 Hz at load 4kΩ; no DC voltage overlay (country-spe-
cific versions also with 25 Hz)
– No control key detection
