Have you looked at your DS1 errors under TCM? That should tell you if you have problems with the signal. Also, your telco should be able to look and see if you have accumulated any slips. On Wednesday, September 29, 1999 2:14 PM, Christopher Arlis Hanes [SMTP:chanes@usacars.com] wrote:

I'm having a problem with static coming and going on my PRIs. The effect then is that users are unable to temporarily dial in - the modems aren't able to negotiate a connection. I'm fairly certain the interference is being produced on the utp cat 5 cable running about 25 feet on a ladder rack from the demarc point to my boxes. I'm planning on installing shielded cable immediately but was wondering if anyone has run into similar problems and has some advice? What is the best way to measure the noise on the line? I noticed under Performance Monitor on modems you can get s/n ratio info for each connection. What are acceptable levels?

Thanks, Chris Hanes
