                        I.  INTRODUCTION

     1.   On February 26, 1999, the Common Carrier Bureau (Bureau) released the Number
Portability Designation Order, specifying issues for investigation with respect to Ameritech
Operating Companies (Ameritech) Transmittal Nos. 1186 and 1187, establishing rates, terms and
conditions for the provision of long-term local number portability.  On May 27, 1999, Ameritech
filed Transmittal No. 1204 proposing new monthly rates for its local number portability query
service charges with an effective date of June 3, 1999.  On our own motion, pursuant to section
204(a) of the Communications Act of 1934, as amended, we suspend Ameritech Transmittal No.
1204 and include Ameritech Transmittal No. 1204 in the investigation of CC Docket No. 99-35.  

                         II.  TRANSMITTAL NO. 1204
                                
     2.   The Number Portability Designation Order sets out the specific issues for the
Bureau's investigation of Ameritech Transmittal Nos. 1186 and 1187.  We find that Ameritech
Transmittal No. 1204 raises the same issues that were set for investigation in the Number
Portability Designation Order.  The Bureau, therefore, designates for investigation with respect
to Ameritech Transmittal No. 1204 all issues set for investigation in the Number Portability
Designation Order for this company.

                    III.   EX PARTE REQUIREMENTS

     3.   This tariff investigation is a "permit-but-disclose proceeding" and subject to the
