Getting help from the Nortel web site

•search the Technical Support Web site and the Nortel Knowledge Base
for answers to technical issues
•sign up for automatic notification of new software and documentation
for Nortel equipment
•open and manage technical support cases
Getting help over the telephone from a Nortel Solutions Center

Support web site, and you have a Nortel support contract, you can also get
help over the telephone from a Nortel Solutions Center.
In North America, call 1-800-4NORTEL (1-800-466-7835).

10 How to get help
Getting help from a specialist by using an Express Routing Code
To access some Nortel Technical Solutions Centers, you can use an
Express Routing Code (ERC) to quickly route your call to a specialist in
your Nortel product or service. To locate the ERC for your product or
service, go to:
http://www.nortel.com/erc
Getting help through a Nortel distributor or reseller
If you purchased a service contract for your Nortel product from a
distributor or authorized reseller, contact the technical support staff for that
distributor or reseller.
