FOREWORD

This diskette set contains the Services Descriptions section of the ONA
Services User Guide, an update of information that was previously issued 
in the July 31, 1990 release of the ONA Services User Guide.

The Services Descriptions section of the ONA Services User Guide represents an 
agreement on the part of the BOCs for uniform names and technical descriptions 
of the BSAs, BSEs and CNSs that relate to the ESP requests included in BOC ONA 
Special Report Number 1, Issue 2 (October 1987).  Some items, marked with an 
asterisk (*) in their titles, have been deleted after the last issue of the 
report based on the availability of updated information indicating that they 
cannot be offered.  For each service listed, a table is provided that gives an
indication of which BOCs plan to offer the service, the individual BOC's 
product name, and whether the BOC classifies the service as a BSA, BSE or CNS.

The BSAs, BSEs and CNSs are each in an individual file, each named using the
service code number used by the ONA Tariff Reference uniform format.  The 
generic services have numbers from 1001 to 1093.  Region specific services 
have numbers as follows:

 o Ameritech - 2000-2009
 o Bell Atlantic - 3001, 3010, 3017 to 3027
 o BellSouth - 4000 to 4016
 o NYNEX - 5001 to 5040
 o Pacific Bell - 6001 to 6005
 o Southwestern Bell - 7000, 7034 to 7035, 7067 to 7069
 o U S WEST - 8001 to 8034, 8099

The utility program to use to view the service descriptions can be run by 
simply typing the command "library" and hitting the <return> key.  The utility 
program will provide the user with several options, including viewing service 
descriptions on the screen, sending the descriptions to an attached printer, 
or writing the descriptions to an output file named "report."  Before the 
"LIBRARY" utility is run, all files should be transferred from the floppy 
diskettes and loaded onto the hard disk of an IBM-compatible computer.  

This report does not supersede any information provided in the BOC ONA plans 
and amendments.  All capabilities described are not available in all switching 
or transmission systems.  The BSAs, BSEs and CNSs identified in this report 
cannot be ordered until appropriate tariffs are effective.  Some ONA services 
may not be tariffed in all areas.  The reader should refer to the individual 
BOC ONA plans and amendments or the BOC contacts listed in Appendix 2 to this 
report for information on BOC availability and deployment plans for the 
technical capabilities described in this report.

References to switching system generics that have not yet been released by the 
vendors are based on our current information about which features are planned 
for inclusion in those generic releases.  If the vendors change the availability
of any features for future generic releases that are referenced in this 
document, the availability of some services may be affected.

Technical references that are publicly available are listed for each service, 
where available.  Ordering information for each of the technical references 
may be found in the Bellcore Digest of Technical Information (including 
ordering information for reference documents published by individual regional 
companies).

Questions on this report should be directed to the BOC contacts listed in 
Appendix 2 to this report.  Appendix 2 is in a file called apx2.
