Placing Your ISDN Order through 3Com
To have your ISDN order placed for you, simply call 1-800-572-3Com.
A 3Com representative will ask what services you require on your
ISDN line, provide the appropriate information to your telephone
company, and schedule an appointment for the installation of your
ISDN line.
Placing Your Order through Your Telephone
Company
To order ISDN service through your phone company, call the company
and ask if they use National ISDN Ordering Codes.
If your phone company uses National ISDN Ordering Codes, go
to the “Using National ISDN Ordering Codes” section of this
chapter.
If your phone company does not use National ISDN Ordering
Codes, ask what sort of ISDN switch type your line will be using.
Take note of the type, then go to the “Ordering by Switch Type”
section of this chapter.
Using National ISDN
Ordering Codes
These codes simplify ordering ISDN service by grouping common
features and capabilities in packages that can be requested by name.
This means that you can order your ISDN service without discussing an
incredible number of parameters one-by-one with your phone
company’s ISDN representative.
Using an ordering code also ensures that the phone line will function
properly with your ISDN equipment.
One of the National ISDN Ordering Codes listed below will likely meet
your needs.
Note: Many other capability packages may be available for your ISDN
line, and many features can be added to your package individually.
However, not all capability packages may be available from your phone
company.
If you have any questions about what is included in a capability
package or how to add something to that package, ask your phone
company’s ISDN representative.
