If You Still Have Problems
If you are attempting to make a connection using HST modulation,
make sure that the modem at the other end of the line is HST
compatible, V.32 terbo compatible at 14.4 Kbps, V.32 compatible at
9600 bps, V.22 bis-compatible at 2400 bps, Bell 212A-compatible at
1200 bps, or Bell 103-compatible at 300 bps.
If none of the above corrects the problem, it's likely that the quality of
the phone connection is poor. The variable quality of phone line
connections may be due to any number of conditions in the phone
service's equipment or the current environment. Try several calls, and
if you still can't get through, try calling another device. If the second
device accepts your call, the problem may lie with the device you first
tried to call.
The problems described above are by far the most common ones that
users encounter. If the suggestions we've given don't clear up your
difficulties, try the following:
1 Review the manual carefully to see if you've missed something.
2 Call or visit your dealer. Chances are that your dealer will be able to give
you the assistance you need. This is much more efficient (and
time-saving) than returning the product to 3Com Corporation.
3 If your dealer can't help you, refer to the Customer Service Access Card
provided in this package. This card lists several important 3Com numbers.
4 If you must return your Business Modem to us, the Service Representative
you talk with will give you a Service Repair Order (SRO) number. Products
without an SRO number will not be accepted.
5 If you do return the Business Modem to us, please follow these
procedures:
a Ship the unit, postage pre-paid, in its original container. If the original
container is not available, pack the unit carefully in a strong box of
corrugated cardboard with plenty of packing material.
b Be sure to include your SRO number inside the package, along with
your name and address. Put your return address and your SRO number
on the shipping label as well.
c Ship the package to the following address:
