3.4.1 Built-in LED indicators
Each Ethernet connector has two built-in indicators.
The left indicator shows the speed of data traffic between the W3x router
and the connected client. If the speed is 100 Mbps, the indicator is green.
When the indicator is unlit, the speed is 10 Mbps.
The indicator to the right is yellow when a LAN connection is established
and flashes to show data traffic activity.
3.5 Telephony Interface (W35 only)
The Ericsson W35 includes dual POTS interface (FxS); the physical ports
marked “Phone” and “Phone/Fax”. The “Phone” port is the primary port to
be used for making CS*-phone calls. The “Phone/Fax” port is intended for
PS*-based telephony services. This support fax machines and
complementary telephony services.
* CS = Circuit switch, the traditional way of supporting telephony services.
* PS = Packet switch, the data-com way of supporting various
communication services, including telephony (also called VoIP).
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).
