Here's the problem: I've got 50 lines coming into my site. I've got multitech Managed Rack 28.8Ks and motorola power modems. Users complain of: 1) Dropped connections 2) Slow connect speeds, 19.2-21.6K on average for 28.8K modems 4800 and 9600 occasionally with 14.4K modems The fact that 14.4K modems can't connect at 14.4K makes me convinced there is a problem. I've never seen that before until they made some changes with my wiring. 3) Unable to connect at all after retraining I talk to the engineer in charge of my central office and he says they can't do anything because they are only required to support 9600 baud. Which in my mind in a bunch of bull. This isn't the 80's anymore Bell Atlantic, wake up. They have suggested 1) I purchase $8K channel banks for each 24 lines and pay an extra $300/mo to bring the lines in on a T1. 2) Try "custoflex" lines which they say are their highest quality. These are only $5 more a month. I'm trying a few of these to see what happens. 3) I am also asking them to check for bridge traps. What I need are suggestions: 1) What can I do to get the phone co to do something. 2) What can I do to get some hard data to show them the problem. I'm willing to purchase some testing equipment. Please help, I am getting desperate.

Custoflex is just another name for Centrex service. As far as I know, the line quality does not change.

Better watch out! Often the degradation of our dial-up lines is the cause of "not the lines" that worked before, but the trunking network. RBOC's will install compression hardware with voice compression, fax bypass, and now... an attempt at dial-up data bypass in the form of voice/fax/data compression concentrators. Unfortunately, although fax bypass is now a relatively mature technology when layered with low rate voice channel encoding (ATC/ADPCM/LD-CELP, etc...) the data bypass end is NOT stable. If we're having dial-up data problems en-masse to a POP all of the sudden, the metallic plant hasn't suddenly becom bad! Something else is wrong. 1. You're beta testing your telco's attempts at compression; without cost benefit. 2. Once your telco gets compression working properly (at your cost... se 1) above). you will spend the same for connectivity while their costs drop dramatically! See your Public Service Commission... they're usually politicians with MBA's on the take... but the hardware changes should be accesible for your local telco should be available through your local PSC... if you live long enough.

>3) I am also asking them to check for bridge traps. Definitely have them check for this. We had some bridge tap on a two pair of wires that was being used by us for a Frame Relay connection. It was enough to cause the signal to degrade a couple of times per day and cause a reset of the connection - took about two minutes to come back up every time. The telco (GTE) finally sent someone out at 3 am with a $125,000 UNIX based pattern testing portable computer to send simulated traffic down the circuit. Finally one of the test patterns reproducibly caused the link to die. The tester was a stickler who wasn't going to leave until he had tried every possible pattern. Even though you're not doing the same application, make sure whoever runs tests on your lines runs every conceivable test...you never know which one will be significant ahead of time!! JPF
