MODIFICATION OF COMMENT AND REPLY COMMENT DATES REGARDING
SIEME NS PETITION FOR RECONSIDERATION OF CALLER IDENTIFICATION RULES

                                   
                                   On July 23, 1997, Siemens Business Communication Systems, Inc. (Siemens) filed a petition requesting
that the Commission reconsider certain of its rules issued in Rules and Policies Regarding Calling
Number Identification Service -- Caller ID, Third Report and Order, Memorandum Opinion and Order
on Further Reconsideration, and Memorandum Opinion and Order on Reconsideration, CC Docket No.
91-281, FCC 97-103 (rel. March 25, 1997).

Specifically, Siemens states that: the Commission's rules are unenforceable against private branch
exchange (PBX) owners/operators because the language of the adopted regulations applies only to
carriers; actual notice of the Commission's rules has not been provided to PBX owners/operators and
will result in widespread non-compliance; manufacturers have only eight months, as opposed to the
needed twenty-four months, to incorporate the required upgrades; the Commission failed to conduct a
cost-benefit analysis before requiring upgrades of currently installed PBX systems; and that PBX
systems should enjoy the same exemptions as granted to Centrex systems that currently use *6 or *8
for dialing functions other than calling party number (CPN) blocking or unblocking.

Siemens recommends that the Commission take the following action: suspend the March 25, 1998
compliance deadline; grandfather all in-place PBX equipment; allow PBX manufacturers at least two
years or until January 1, 2000 to incorporate CPN blocking and unblocking signaling in new PBX
equipment; allow PBX systems the same dialing exemptions allowed Centrex systems; and clarify
which PBX signaling methods are acceptable for passing CPN blocking and unblocking information. 

On September 26, 1997, a Public Notice was issued establishing October 3, 1997 as the deadline for
filing comments in the above captioned proceeding.  We hereby modify those deadlines.  Interested
parties may file comments concerning this matter on or before 15 days from publication of this Public
Notice in the Federal Register.  Reply comments may be filed within 10 days after the date for filing

Commission, 1919 M Street, N.W., Washington, D.C. 20554.  Copies of documents filed with the
