- 25 - METHOD AND APPARATUS FOR CONTROLLING A DIGITAL CROSSCONNECT SYSTEM FROM A SWITCHING SYSTEM Abstract This invention relates to apparatus and a method for controlling a Digital Access and Crossconnect System (DACS) from a connected toll switching system. All control messages from operations support systems (OSS) for making crossconnect changes in the DACS are first routed to the toll switch. The toll switch extracts information needed to update its database and sends a control message to the DACS. In addition, the toll switch responds to changes in traffic patterns, perhaps due to the loss of a transmission facility, to generate a crossconnect change message to the DACS to rearrange facilities for more optimum performance. Advantageously, the OSSs for DACS control and switch control is combined and thetoll network is made more responsive to traffic pattern changes and to losses oftransmission facilities.
