Clare recommends two (2) approaches. The modem should either use a no clean soldering flux that would mostly evaporate during the normal wave soldering processes, or be soldered in by hand after the rest of the card is wave soldered.

Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and effect its reliability.

N/C Keying pin for CYG2000/CYG2001, do not use. 8 I OH Driving this pin LOW asserts the off-hook condition. The hookswitch LED is current limited by an internal 470 resistor. 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 CYG2020/2021/2030/2031. CID1/CID2 connect to an external 1-Form-A solid state relay (CP Clare 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 hookswitch LED. Typically +5V for 8mA LED current. LED is current limited by an internal 470 resistor. VCC should not exceed 20V.
