Spring Brings Some Jeffersonians a New Telephone Exchange - 503

Effective April 15 at 7 p.m., personnel in six Jefferson buildings will be assigned a new telephone prefix ­p; 503. These individuals will retain their existing four-digit extension. The 503 exchange will be used for telephones and voice mail boxes as well as fax and computer modems currently using the 955 exchange in the Bluemle, Edison, Jefferson Alumni Hall, Martin, Scott and Sheridan buildings. Only highly publicized and clinical practice numbers in these buildings will retain the 955 exchange. All callers using the old exchange after April 15 will hear a new number message for 90 days.

To test how the new exchange will work, on March 4 at 7 p.m., the department of information systems (DIS) will change all of its 955 exchange to 503. After 7 p.m., call DIS using a "3" before the last four digits of the extensions you want to reach.

"Because we are rapidly approaching using all of the 10,000 numbers originally available to us in the 955 exchange, the decision was made to assign the 503 exchange to those areas less likely to impact consumers and clinical service related areas," said Al Giacomucci, acting director, department of information systems. "Implementing use of the 503 exchange in this way, makes it possible for Jefferson to retain the 955 exchange in our clinical areas."

Departments affected by this change will soon receive information from the department of information systems graphics and printing center concerning how to go about changing letterhead, business cards and buck slips and how to order postcards to notify those outside the University of their new number.

It's important at this time that you notify telecommunications to disconnect lines no longer in use yet still accruing charges, said Betsy McMenamin, support services manager, department of information systems, who will implement installation of the 503 exchange. This will free up scarce 955 numbers for reassignment in clinical areas.

If you have questions about the 503 exchange, please call the hotline at 3-9999. Your questions and concerns will be directed to Betsy McMenamin.
