atcomsystems.ca/forum Forums General General Telephone & Systems Information low co volume

All of the responses are good but you left out the fact the call terminus was a call center. Call centers use 800 numbers so customers can reach them. The 800 equipment can be located anywhere in the US. If call volume exceeds design then calls are redirected to backup systems. All other things being equal, the problem is in the 800 equipment.

thanks jr
i didn't even think about 800 wild card.

after reviewing phone logs it looks like there are vol issues ingoing and outgoing
but 99% long dist

Sounds like the LD provider. If they are handling 800 calls coming in, and LD calls going out, then it is all going through their switches. Also, if their call volume is high, it is normal to get a small amount, say 2-3% of calls, that have low volume or another issue.

thnks a lot i sure appreciate everyone input
on this.

i hear ya brother

We had a similar problem with Norstar ICS. We were aware that the Copper in the area was crappy and had MCI test lines and Qwest test lines and sometimes they were good and sometimes they weren't. Our customer kept logs. We recommended to our customer to go with T1. They did and they are extremely pleased. It also provided them with the opportunity to have DID's. (PS..this went on for over a year until they got T1)

As a %ess technician and 1st level support for a major phone company, I may be able to shed some light on the subject. It is the 21st century. Most major LD company's will trunk using T1 or T3 fiber equip. Our company is like any other, we are 100% digital between offices. This kind of problem rarely comes about anymore, but some reasons could be lousy copper feeding customer, lack of loading coils or right at the edge of the CO service area. Loss on the copper and 1000hz to customer site should be -5db max in the copper. The signal comes off in the CO at 0db. There are a number of other factors. SLC's, DLC's, Remotes fed by t1 copper or fiber. In these situations, sometimes the trunking to connect to the world is not at the serving CO, it would be back at the Host office that could be hundreds of miles away. Since it is long distance where the problem seems to lie, the TANDUM switch could be anywhere in the nearest major metropolitian area.Levels are always run at levels to keep things in order at the CO. My suggestion is to have the phone company and you go to the site and measure the loss between your site and the CO. If they are off, they could add amplifiers(7306 westcoms) on each line to increase volume. You may also want to check the PBX and see if there is a 3db amp increase available on the PBX itself. One could also check the DB loss simply by using a transmission test set and dialingthe local 1000hz signal at the CO and reading the loss. Use 600 ohms and use the holding coil on the transmission set to hold the line after dialing. A T1 just seems quite expensive for a few lines. Brad

appreciate your's and all the other feedback on this subject. like you said this is not a common issue anymore. i have not done a loop test but i believe i have the equipment. my truck is gone right now so i can't give you the tester i have but it is meter i bought from mike sandman. i use it mostly for loop current. not exactly sure of the procedure though. when my truck is back i will post meter type. by the way the would max out a t-1 quick they already are using a frac for data.
ok truck is back the meter is a triplett 2
in addition to acv,dcv and ohms i have ckt it has loop ma, power inf, ckt noise and ckt loss(which is the test i need) i'm not sure how to seek the 1000hz from the co. call repair? i understand sandman may have a 1000hz generator.
