Abstract

1,179,508. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Oct., 1967, No. 24410/69. Divided out of 1,179,507. Heading H4K. In an exchange in which an initial dialling connection is set up to a register and then, if an outgoing call is involved, an outpulsing connection from the register to a trunk is set up whereafter a direct connection between the caller and the trunk is completed, the initial path via the register may be used as a speech connection if a direct connection can not be set up due to internal blocking. The dialling connection may also be used as a speech path for a local call in the event of congestion. Mechanically latched cross-bars similar to those described in Specification 1,124,932 may be used. Overflow connections may be set up in the manner described in Specification 1,179,507.
