N/C Keying Pin for CYG2000, do not use. Driving this pin LOW asserts the off-hook condition. The hook switch LED is current limited by an internal 470 resistor. 8 I OH 9 O RING Active LOW indicates an incoming ring signal. This is pulsed LOW by the AC ring signal at the ring frequency from 15-40Hz. 10 I/O RING Connection to telephone line Ring conductor. 11 I/O TIP 13 O CID2 Caller ID connection on CYG2020. CID1/CID2 connect to an external 1-Form-A solid state relay (IXYS IC Division LCA110). When the SSR is closed (connecting CID1 to CID2) Caller ID information is presented to LINE1/LINE2 after the first telephone ring burst. 14 O CID1 Caller ID connection. See CID2 above. 17 I GND Connected to host system ground. 18 I VCC Provides power to the hook switch LED. Typically +5V for appx. 8mA LED current. LED is current limited by an internal 470 resistor. VCC should not exceed 20V.

IXYS Integrated Circuits Division recommends two (2) approaches: (1) the modem should be installed in a wave-soldering process that uses a no-clean soldering flux that will mostly evaporate during the normal wave-soldering processes, (2) the modem should be soldered in by hand after the rest of the card is wave-soldered. 4.2 Reflow Profile These products have a maximum solder temperature as shown below.
