Telco: Optimum Online (Cablevision) severed by cable modem (Motorola Surfboard) with two lines
Problem with call waiting dropping calls
After third call waiting tone is heard in handset the original call is dropped. The second caller will get into Optimum Online voice mail as expected.
If a SLT is connected directly to the Cable modem phone jack a click is heard on the line after the third call waiting tone but the call is not dropped.
Any help is golden.

You must understand call waiting interrupts the system.....just like you trying to hang up.
Your "dial tone" is not dial tone.....it is reproduced by the line conditioning at the modem.
First, get rid of Call Waiting.
Second, get Optimum Online to set the modem correctly to operate correctly.
Third, get real dial tone is another option to take care of Second item.
Good Luck.
The CPC setting on the system needs to be adjusted. An SLT isn't smart enough to understand what the click you are hearing means, so nothing happens with the test call. The click you report hearing may be just enough of a drop in the loop voltage to signal (tell) the system to drop the call. This is also a problem when lines are served from a #1 or 1AESS office.
Panasonic systems have settings under CO Line parameters to address what they refer to as "CPC" or "Calling Party Control".
Thanks for the replies.
The three options given by KLD are kind of what I suspected are the problems. The next challenge is to convince optimum that the problem is theirs. I have been able to educate techs about cable TV transmition so they could correct TV problems. How and what would I ask to get them to correct this shortcoming. Optimums know it all "engineer" has all the answers as to why it is the telephone systems problem.
Ed, if "CPC" or "Calling Party Control" adjustment can alleviate the problem without involving optimum, wow. What settings would you recommend be tried? Can this be adjusted by telset programming?
Thanks again,
Bill
Ed, you are THE man.
Tried different "CPC" settings but found disabling the feature resolved the problem.
KLD, you are right, these VOIP companies are the problem because they are not subject to the regulations that are imposed on CLEC's to standardize the dial tone. I think government should step in here and impose the same regulations. What you say?
Went through Panasonic support but they wanted the customer to get a business modem which have better dial tone standards.
Thanks again guys, keep up the good work.
