    7、ational telephone traffic statisticsColumn 1 Designation of the connection by giving the name of the outgoing exchange first and then thename of the incoming exchange. Two-way connections will be shown in alphabetical order.Columns 2 and 3 Number of circuits in operation as on 31 December of the yea

    8、r of the statistics.The number will be shown in column 2 when it refers to outgoing circuits and in column 3when it refers to both-way circuits.Columns 4 and 5 Number of circuits which would have been required during the year of the statistics.Column 6 Method of operation.The following abbreviations

    9、 will be used:A for automatic,SA for semiautomatic,M for manual,A + SA for automatic and semiautomatic.Column 7 Destination of traffic.Each relation will be shown in this column on a separate line.In the example given, the traffic routed over the Zrich-Kbenhavn circuits is destined forDenmark (termi
