This is very true - Here's where the confusion comes from: apparently in a 5ESS switch, when you provision a pri, it can be configured as a 5ESS (sometimes called "Custom" or "5ESS Custom" by the telco) and can also be configured as NI2 (sometimes referred to by the telco as "standard"). It's apparently VERY easy for your telco to provision a PRI to what they call "standard" (requiring the NI2 settings), but when you ask them what type of switch it is, they'll say 5ESS, which is in fact the type of switch, but not the type of PRI you have. The behavior Matthew describes is similar to what I've experienced when you have an NI2 PRI and set the DSP for 5ESS. Intermittently losing B-channels and/or D-channels. - Joel -----Original Message----- From: Paul Farber [mailto:farber@admin.f-tech.net] Sent: Tuesday, April 08, 2003 8:58 PM To: Discussion relating to the 3Com/US Robotics Total Control modem systems. Subject: RE: [USR-TC] need help! hiper dsp/pri keeps going to Biggest one will be Switch type. Some switch type are 'close' - 5ESS and NI2 are ones that I had problems with. The switch type was NI2 but my DSPs were at 5ESS... worked for a while but would drop B's, go remote out of service and other errors. Verify your line coding and switch type with telco... have them fax it to you if they can so if it changes you can show them. -- Paul Farber Farber Technology farber@admin.f-tech.net Ph 570-628-5303 Fax 570-628-5545 On Tue, 8 Apr 2003 matthew@the-spa.com wrote:

i did load all the settings from the first hiper dsp in that chassis.

i have to call the telco tomorrow and have them review all of their settings just in case that might be it.

thanks

...

Maybe have the telco confirm the new PRI is setup exactly the same as the rest of them....assuming you checked ALL the config settings to confirm they are the same. Best bet would be to just load all the settings from one of the other dsps...you can do that from tcm.

ok here is the situation...

i have a chassis with 11 hiper dsp's active, dual hiper arc's and a hiper nmc and dual 130's

i had 10 pri's running fine for the last two months.

added the 11th pri yesterday. it seems to run fine for a few hours, fills up with callers etc.

then it will get less "busy" than the rest of them, until it has nobody on it.

when i check it all of the channels are remote out of service.

if i do a hardware reset it goes back to normal for a few hours and then it does it all over again.

i have checked all of a the settings and i can't figure out what is wrong.

it seems to be identical to the other 10 pri's/hiper dsp's

same version etc.

can someone help me please?

thanks

matthew
