1. Switch Type—Verify the switch type information with your
telephone company. For North America, select the type of

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.

router with another device on the S/T bus, then select
Switch/Unused. If not choose Switch/Switch. The following
