Some telephone connections simply wont support the movement of data

at the rates required by the Vector. If you have trouble establishing a

reliable connection even with a speed drop, try redialing several times.

The telephone systems often route calls differently each time, and you

may pick up a cleaner circuit on a different call. The problem may also be

that your local loop runs a very long distance, is subject to cross-talk, or is

loaded by the phone company, causing the modems in the Vector (or

any modems, for that matter) to perform poorly. If possible, try a different

line. Finally, we find a change in long distance carriers (assuming you are

dialing long distance) can make a world of difference. Try dialing the

access code of a different carrier if you have difficulty, see page 36 for

some access codes. In general we find better connections with the larger

carriers (avoid Joes phone company if possible).

Vector performance can be affected by factors such as time of day,

weather, and geographic location. Once you have used the Vector, you

will probably gain a better understanding of how it works on different

lines and what can go wrong.

If you call Comrex for support, we will likely attempt to connect to each

of your Vectors from our office. This way, by connecting from a known

good line and carrier, we can often at least isolate which end of the

connection is causing the difficulty. To save your time and ours, please be

sure you have run through the above checklist before calling for support.
