Arrangement for assembling an initial entry in a billing buffer

Claim 2

In a communication system using a multi-entry format including an initial entry, an answer entry and a disconnect entry for recording call records, the data comprising the initial entry being accumulated by a call processor and stored in a call processor call store and an initial entry pre-store, said data from said call processor call store and said initial entry prestore being assembled in a billing buffer to complete one initial entry, said system comprising a core memory having one portion thereof which forms at least one call processor call store and another portion thereof which forms said billing buffer, an initial entry pre-store, a data bus, a call store read buffer, and a data selector, said data selector being operable during a first pre-established time interval to couple said initial entry pre-store to said data bus to permit the data stored therein to be transferred into said billing buffer, the data stored in said call processor call store being read into said call store billing buffer during the time interval said data is being transferred from said initial entry pre-store into said billing buffer, said data selector being operable during a subsequent second time interval to couple said call store read buffer to said data bus to permit the call store data stored therein to be transferred into said billing buffer, and control means for establishing said first and second pre-established time intervals.

Claim 3

In a communication system using a multi-entry format including an initial entry, an answer entry and a disconnect entry for recording call records, the data comprising the initial entry pre-store being assembled in a billing buffer to complete one initial entry, said system comprising an initial entry pre-sotre, a data bus, a call store read buffer, and a data selector, said data selector being operable during a first pre-established time interval to couple said initial entry pre-sotre to said data bus to permit The data stored therein to be transferred into said billing buffer, the data stored in said call processor call store being read into said call store billing buffer during the time interval said data is being transferred from said initial entry pre-sotre into said billing buffer, said data selector being operable during a subsequent second time interval to couple said call store read buffer to said data bus to permit the call store data stored therein to be transferred into said billing buffer, and control means for establishing said first and second preestablished time intervals, said call processor upon storing all data pertinent to a call in said call processor call store requesting access to said billing buffer while the first word stored in said call store is read, said initial entry pre-sotre being coupled to said data bus and said data stored therein being transferred into said billing buffer during the time allotted to read three additional words stored in said call processor call store, said initial entry pre-store being disconnected from and said call processor read buffer being coupled to said data bus when the data stored in said initial entry pre-store has been transferred into said billing buffer to permit the data stored in said call store read buffer to be transferred into said billing buffer.

Claim 4

In a communication system using a multi-entry format including an initial entry, an answer entry and a disconnect entry for recording call records, the data comprising the initial entry pre-store being assembled in a billing buffer to complete one initial entry, said system comprising an initial entry pre-sotre, a data bus, a call store read buffer, and a data selector, said data selector being operable during a first pre-established time interval to couple said initial entry pre-sotre to said data bus to permit The data stored therein to be transferred into said billing buffer, the data stored in said call processor call store being read into said call store billing buffer during the time interval said data is being transferred from said initial entry pre-sotre into said billing buffer, said data selector being operable during a subsequent second time interval to couple said call store read buffer to said data bus to permit the call store data stored therein to be transferred into said billing buffer, and control means for establishing said first and second preestablished time intervals, said call processor upon storing all data pertinent to a call in said call processor call store requesting access to said billing buffer while the first word stored in said call store is read, said initial entry pre-sotre being coupled to said data bus and said data stored therein being transferred into said billing buffer during the time allotted to read three additional words stored in said call processor call store, said initial entry pre-store being disconnected from and said call processor read buffer being coupled to said data bus when the data stored in said initial entry pre-store has been transferred into said billing buffer to permit the data stored in said call store read buffer to be transferred into said billing buffer.
