- Patrick, I just came across this in my new issue of [Telephony] and
- thought it would be of interest to the Telcom Digest group. In my
- opinion it is a very well written article. There is a lot of
- interesting information in this short article.

- DIALING AWAY U.S. AREA CODES

- The current endangered species in the news may not be an animal at
- all. The number of available area codes in the United States is
- dwindling rapidly. Chicago consumed a new code Nov. 11 and New Jersey
- will gobble up another one on Jan. 1.
-
- There are only nine codes left, and they are expected to be used up
- by 1995, said Robert McAlesse, North American Numbering Plan administrator
- and member of Bellcore's technical staff.
-
- "In 1947 (Bellcore) started with 86 codes, and they projected
- exhaustion in 100 to 150 years. They were off by a few years,"
- McAlesse said.
-
- When the 152 available codes are exhausted, Bellcore will use a new
- plan for creating area codes.
-
- A total of 138 codes already are assigned. Five of the remaining
- 14 codes are reserved for service access codes, and 9 are for
- geographic area codes.
-
- Under the current plan, a 0 or a 1 is used as the second digit
- while the first and last digits can range between 2 and 9. Under the
- new plan the first digit will be between 2 and 9 and the following two
- digits will be numbers between 0 and 9, McAlesse said.
-
- The new plan will create 640 potential area codes, he
- said. Bellcore isn't predicting when the newly created codes
- will run out.
-
- "The growth in new services and increase in the number of
- telephones are exhausting the codes. The biggest [increases] are
- cellular telephones, pagers, facsimile machines and new services that
- can have more than one number," McAlesse said.
-
- The current unassigned codes include 210, 310, 410, 706, 810, 905,
- 909, 910 and 917. The Chicago area took the 708 code, and New Jersey
- will take 908.
-
- In the Chicago metropolitan area, the suburbs were switched from
- the 312 area code to the new 708 code. Residents and businesses
- within the city limits retained the 312 code.
-
- Illinois Bell started preparing for the change two years ago with
- the announcements alerting business customers to change stationary and
- business cards, said Gloria Pope, an Illinois Bell spokeswoman. Now
- the telco is targeting the residential market with billboard reminders
- and billing inserts.
-
- The cost of technically preparing for the new code, including
- labor, is expected to reach $15 million. But Pope said that does not
- include mailings, public relations efforts and business packages
- designed to smooth out the transition. The telco will absorb the cost
- with budgeted funds, and no rate increase is expected, she said.
-
- Modifying the network to recognize the new code started about six
- months ago with translation work. Every central office in the Chicago
- Metropolitan area was adapted with a new foreign-area translator to
- accept the new code and route the calls correctly, said Audrey Brooks,
- area manager-Chicago translations.
-
- The long distance carriers were ready for the code's debut. AT&T,
- US Sprint and MCI changed their computer systems to recognize the new
- code before the Chicago deadline.
-
- "We are anticipating a pretty smooth transfer," said Karen Rayl, US
- Sprint spokeswoman.
-
- Businesses will need to adjust their PBX software, according to
- AT&T technical specialist Craig Hoopman. "This could affect virtually
- every nationwide PBX," he said. Modern PBX's will take about 15
- minutes to adjust while older switches could take four hours. In many
- cases, customers can make the changes themselves, he said. [END]
