CYG20XX Pinouts & Definitions
Function
Transformer isolated audio signal coupling path for the telephone line.
Transformer isolated audio signal coupling path for the telephone line.
When system is off-hook (OH driven LOW) LOOPI is driven LOW continuously
on CYG2010/2011/2030/2031 devices.
Keying pin for CYG2000/CYG2001, do not use.
Driving this pin LOW asserts the off-hook condition. The hookswitch LED is cur-
rent limited by an internal 470Ω resistor.
Active LOW indicates an incoming ring signal. This is pulsed LOW by the AC
ring signal at the ring frequency from 15-40Hz.
Connection to telephone line Ring conductor.
Connection to telephone line Tip conductor.
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.
Caller ID connection. See CID2 above.
Connected to host system ground.
Provides power to the hookswitch LED. Typically +5V for ≈ 8mA LED current.
LED is current limited by an internal 470Ω resistor. VCC should not exceed 20V.
