Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
A telephone call distribution system for handling a special type call, said call containing at least automatic number identification (ANI) data, comprising: at least one central switching location for receiving said call and having means for processing; means for interfacing with an automatic location identification (ALI) data base having ALI data associated with said ANI data, said means for interfacing receiving said ANI data from said means for processing and returning said ALI data to said means for processing, and having means for storing said ALI data associated with said call; and means for connecting said means for processing to at least one remotely located terminal means for receiving said call, said means for processing also sending said ALI data to said terminal means.
Claim 2
Dependent Claim
124 words
A telephone call distribution system for handling a special type call, said call containing at least automatic number identification (ANI) data, comprising: at least one central switching location for receiving said call and having means for processing; means for interfacing with an automatic location identification (ALI) data base having ALI data associated with said ANI data, said means for interfacing receiving said ANI data from said means for processing and returning said ALI data to said means for processing, and having means for storing said ALI data associated with said call; and means for connecting said means for processing to at least one remotely located terminal means for receiving said call, said means for processing also sending said ALI data to said terminal means.
Claim 3
Dependent Claim
18 words
The telephone call distribution system of claim 1, wherein said means for connecting is a two-wire pair line.
Claim 4
Dependent Claim
27 words
The telephone call distribution system of claim 1, wherein said ALI data is sent to said terminal means before said call is received by said terminal means.
Claim 5
Dependent Claim
