1.Switch Type - Verify the switch type information with your telephone company. For North America, select the type of switch used by your telephone company. If your switch type is not currently shown, press the space bar to change to the next switch; repeat until you see the correct switch type. The Prestige will not be able to place or to receive calls if the wrong switch type is specified. If you are not sure, contact your telephone company to confirm the exact switch type.

2.B Channel Usage - If you are using one B channel of your Prestige with another device on the S/T bus, then select Switch/Unused. If not choose Switch/Switch.

3.Telephone Number(s) - Enter the telephone number(s) assigned to your ISDN line by your telephone company. Some switch types only have one telephone number. For North America, these phone numbers should be in a standard seven digit format (for example, 5551212). Note that the Prestige only accepts digits; do not include - and spaces in this field. This field should be no longer than 19 digits.

4.Analog Call - This tells the Prestige how to route an incoming analog call. Set to Phone1 if you wish to route the incoming analog call for this telephone number to the PHONE port 1 (a.k.a., POTS port in North America and A/B Adapter in Europe). Set to Phone2 if you wish to route the incoming analog call for this telephone number to PHONE port 2. Set to DOVBS if you wish to receive incoming Data Over Voice Bearer Service call.

5.SPID Number(s) - SPIDs are numbers used by a switch for identification purposes. Depending on your switch type, you may have zero, one, or two SPIDs assigned to your line. For example, if your switch type is Northern Telecom Custom, you will have to enter two SPID numbers.
