Support web site, and you have a Nortel support contract, you can also get
help over the telephone from a Nortel Solutions Center.

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

distributor or authorized reseller, contact the technical support staff for that
distributor or reseller.
