[VoIP] AECo 801 Test Handset (Buttinsky) question

[Steph Kerman]

The 801 is the orange test set with small "Styleline" dial.

According to GSP 100-203-100 Issue 3, "a low pass filter kit ... 
consisting of an inductor assembly ..., an inductor assembly holder ... 
and a resistor-capacitor assembly is available.  This filter kit allows 
the 801 hand test telephone to attach to customer carrier lines without 
disruption of carrier frequencies."  The kit is installed on the 
receiver bracket assy. 

Does anyone own an 801 containing this kit? 

Thanks
Steph
