This document is a virtual replica of hardcopy filed with the Public Service Commission of Maryland on Monday, June 3, 1996. An electronic copy was not available from the PSC and therefore the text of the Bell Atlantic tariff filing was re-entered into electronic form from the hardcopy source document. Please note three points. First, the official document is the hardcopy on file with the Public Service Commission. Individuals who wish to participate in the PSC proceeding or rely upon the tariff filing are advised to obtain an official copy from the PSC. Second, although efforts have been made to ensure that this electronic version accurately reproduces the contents of the hardcopy filing, it is possible that discrepancies exist. Please notify us of any discrepancies between the official hardcopy and our electronic reproduction. Third, this electronic copy does not contain the entire 6/3/96 tariff filing. Several pages were omitted. Those pages principally show the tariff pages as they will exist if the proposed Bell Atlantic tariff is approved in its entirety. New material proposed by Bell Atlantic is indicated by underlining thus. Revisions to existing test are marked by hard brackets [thus] for deletions. Text inserted by the typist is indicated by enclosure in asterisks *thus*. Bell Atlantic Letterhead Bell Atlantic - Maryland, Inc. John W.

Very truly yours, FILED *illegible signature* JUN 03 1996 PUBLIC sERVICE COM=N for *handwritten* OF MARYLAND Vice President External Affairs Description of Filing Establishment of regulations, rates and charges for Residential IntelliLinQ BRI Service and elimination of the trial. This filing provides for establishment of regulations, rates and charges for Residential IntelliLinQ Service and elimination of the trial. This tariff filing modifies rates for Residential IntelliLinQ BRI Service and there are several changes to the existing tariff other than the new price structures. The change charge has been eliminated completely. The cost for making changes to accounts has been covered in the non-recurring charges. In addition, "Secondary Directory Number" has been renamed "Additional Directory Number" in order to reduce customer confusion. Also, "Point to Multipoint" has been added as a rate item. This was included in the previous tariff as part of "Circuit-Switched Voice Service/Circuit-Switched Data Service/Alternative Circuit-Switch Voice and Data Service". Again, this item was segmented to lessen customer confusion of the tariff offering. Withdrawal of Residence PBX Trunks. This filing provides for withdrawal of Residence PBX Trunks. There are currently no units in service and Residential PBX Trunks has no customer demand. We believe it would be best to eliminate the service to reduce customer confusion.
