Description
The CYG2000/2001/2010/2011/2020/2021/2030/2031
are Data Access Arrangement (DAA) modules featuring
a 350V, 120mA, 15Ω relay used for hookswitch, optocou-
pler with minimum CTR of 33% for ring detection, and a
low distortion transformer with 28.8kbps capabilities.

Handling and Assembly Recommendations
The CYG20XX products are not hermetically sealed and should not be exposed to any liquid-based rinsing processes. 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.
