Path: utzoo!telecom-request Date: Fri, 14 Jun 91 10:06:18 EDT From: Carl Moore (VLD/VMB) Newsgroups: comp.dcom.telecom Subject: COCOT Regulations With Reference to New NPA and Prefix Message-ID: Organization: TELECOM Digest Sender: Telecom@eecs.nwu.edu Approved: Telecom@eecs.nwu.edu X-Submissions-To: telecom@eecs.nwu.edu X-Administrivia-To: telecom-request@eecs.nwu.edu X-Telecom-Digest: Volume 11, Issue 457, Message 7 of 12 Lines: 19 I just got a message about some COCOTs not recognizing area codes 903 and 908, both of which have been fully cut over. Do the proposed or current COCOT regulations require up-to-date information for new area codes and prefixes, or did I overlook something in skimming over the mail? Failure of a system to recognize a new area code or prefix can be quite annoying, and my office (in eastern Maryland) is getting a new area code before this year is out. Over the years, I have heard (in this Digest and elsewhere) about problems in recognizing the following: N0X/N1X prefixes in Los Angeles area before 1980 (that's when New York City started getting them); 301-850 at or near the Baltimore-Washington International Airport; 202-994 in Washington, DC; 508 area code in Massachusetts.
