Table Initialization in a Telephone Exchange
This article describes a method for selectively initializing tables fro a table
disk, a maintenance keyboard, or both in a stored program-controlled telephone
exchange at Initial Program Loading (IPL) time.
The proposed method is implemented by an initialization program which is
capable of processing a table disk which has been created by a system other
than the telephone system, and which may use any data format. The program
converts data from the table disk into data having a format executable by the
telephone system and stores the later data into a system disk. Data from the
table disk can be modified and new data can be entered into the tables through
the maintenance keyboard. The program permits the updated tables to be copied
into the table disk for further use.

If options Ynd and No are selected, all the table elements are entered into the
system from the table disk or the keyboard, respectively. If option Yes is
selected, the following message is displayed to the operator: 01 . Stop on each
