CENTRAL OFFICE SWITCH

The UTA220 is designed for easy programming and operation. Using the front panel LCD display and push-button, the UTA220 can be set up for one of the following central-office switches:

•National ISDN-1

•NTI DMS100, BCS-30, BCS-31/32 or

•AT&T 5ESS, 5E4.2, 5E5, 5E6

Programming the UTA220 requires the following information, which is provided by the telephone company:

•Switch type and version

•Terminal Endpoint Identifiers (TEI)

•Service Profile Identifiers (SPID)

•Directory Number (DN) strings (only supplied with National ISDN and NTI DMS100 lines)

This information identifies the UTA220 to the telephone company. Until the UTA220 has been programmed with this information, the telephone company will not recognize the terminal adapter, and calls cannot be placed.
