    摘要: A modular Common Channel Interoffice Signaling (CCIS) system is described for use with an electronic switching office. This system provides for minimal impact to the program instructions of the switching office. Virtually all modifiable CCIS program instructions are contained within the CCIS system. Therefore, any feature changes or additions to the CCIS system affect only the CCIS system and not the switching office. In addition, the central processing arrangement of the present CCIS system operates a large number of analog and/or digital transmission devices for CCIS data transfer.
