ABSTRACT OF THE DISCLOSURE An automatic number identification system in a tributary office having simultaneous dual operation for high traffic capacity. A pair of identifiers operates in a tributary office through a common directory number network to simultaneously identify two calling stations. Each of the identifiers, having been seized by a trunk circuit requiring calling number ident- ification, initiate a program which applies an identification pulse through the local switching equipment to the sleeve lead of the calling line. The pulse is of relatively short duration compared with the program time. The first of the two identifiers to generate its pulse inhibits pulse generation in the outer identifier during the period of the program when the first pulse is traversing the common number network and the first identifier is detecting and storing the directory number significance of the pulse. When the line associated with the first pulse has been so identified, the second identifier is released to generate another pulse for application to the sleeve lead of the calling line associated therewith. Both identifiers then proceed sim- ultaneously to complete their respective identification programs and transmit the calling numbers to the toll center via the connected trunk circuits.
