3.5 Telephony Interface (W35)
The Ericsson W35 includes dual POTS interface (FxS). The port marked
“Phone” is the primary port to be used for making phone calls. The other
port (marked “Phone/Fax”) is intended for fax machines and
complementary telephony services.
The ports are intended for on premises phones and should typically be
connected to devices within one building. Short loops (max 500Ω) are
supported.
The maximum ringing load for each port is 3 REN (corresponding to three
(3) old fashioned phones with mechanical bells or twenty (20) modern
phones with electronic ringing).
Characteristic impedance, gain, current etc of the ports are controlled by
software. DTMF dialing is supported. The ports have protection to prevent
the unit to be damaged by ESD (Electro Static Discharge).
