Only thing is... he is reporting that the use of the phone does not disconnect service, just the ringer ringing disconnects it. I'm not sure that the Ringer has anything to do with the 2.4Ghz spectrum block. Or I should say, it would not use anymore spectrum ringing than Talking. I'd guess

How would the handsets know to ring if not told by the base via 2.4? It is probably making more noise while ringing than off hook. Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373 On Dec 27, 2011 8:33 PM, Tom DeReggi wirelessn...@rapiddsl.net wrote:

No, actually the ringing is generated by the handset from the power in its battery. The command to ring is just a series of 1's and 0's sent from the base unit to instruct the handset to ring. On 12/27/2011 5:40 PM, Josh Luthman wrote: How would the handsets know to ring if not told by the

The ringing current from the Telco to the base unit is 120 cycles per second AC. It would be more like AC hum on a sound system. I would bet the 2.4 phone system is using most if not all the band at pretty low power. Probably it is the wake up and setup for a call that is knocking out the ISP

What I'm getting at is what initiates the ring. The copper pair hits the base unit and then tells all the handsets in the house to ring. I'm suggesting that this is 2.4 and what causes the SM's problem. I've seen a ringing telephone cause a Dlink router to reboot 100% of the time, it was easily

Yeah, I am sure there is a huge amount of data transferred in the wake up command. The handsets go into a sleep mode to give max battery life. The ring command is probably just all 0's or all 1's like the old frame relay connections use to tell the other end to loop back. The actual talk data

Something about the ringing signal sent by the base to the handsets is different. My dad had wireless headphones that received a horrible pop when the cordless phone rang, but there was no interference when talking on the phone. That same phone used to interfere with 2.4 wifi. We switched to
