Sending ABCD signaling on a PCM-4?

[DeanB]

Ancient business here.  Does anyone know the command for sending ABCD signaling from a PCM-4?  Is it "V731,?"? D>A mode of course - half channel.

Hi Dean,

I checked around here at NI to see if we had any information on the W&G PCM-4, but didn't find anything.  It also appears that W&G's website is not up www.wg.com.  The only suggestion I have is to try to hunt down a user's manual, and keep posting in other forums.

Good luck and happy hunting,

W&G doesn't even exist as a company anymore. They merged with TTC to form Acterna 5 years ago and now Acterna has been purchased by JDS Uniphase. I do a lot of pcm testing and have a lot of Acterna/TTC equipment but unfortunately, not the old W&G equipment. I couldn't find anything on Acterna's web site either but a call to customer service might work. A lot of used test equipment vendors list the PCM-4 as being available with manuals and though it probably won't be free, that might be the only option.
