Reference Guide for the Model RT328 and Model RH348 ISDN Routers

ISDN Menus

Menu 2 is for configuring your ISDN line. Depending on what switch the telephone company has for your particular installation, you may have more than one telephone number. If you are in North America, you may also have SPIDs (Service Profile Identifiers). Make sure that you have correct and complete telephone numbers and SPIDs. You must complete the ISDN setup before your

system can make an outgoing call or answer an incoming call.
