Information recording system

Claim 2

In a telephone system having lines, the combination comprising a memory store including a plurality of storage locations selectively connectable to each of said lines, means responsive to a service request signal from a calling one of said lines for coupling said calling line to one of said storage locations addressable by a line location number determined by said request signal, and means responsive to additional signals transmitted from said calling line for enabling said coupling means to couple said calling line to different ones of said storage locations independently of said determined line location number.

Claim 3

In a telephone system, the combination set forth in claim 1 further comprising means enabled by said request signal for automatically registering said determined line location number identifying said calling line, and wherein said enabling means comprises means enabled by said additional signals for deleting registration of said determined line location number in said registering means and for substituting therefore line location numbers defined by said additional signals.

Claim 4

In a telephone system, the combination set forth in claim 1 further comprising means for automatically identifying a class of service of said calling line.

Claim 5

In a telephone system, the combination set forth in claim 3 wherein said enabling means further comprises first register means selectively connectable to said calling line for registering line location numbers defined by said additional signals in predefined register locations.

Claim 6

In a telephone system, the combination set forth in claim 4 further comprising second register means for automatically recording said determined line location number of said calling line.

Claim 7

In a telephone system, the combination set forth in claim 5 wherein said enabling means further comprises logic means enabled by said identifying means in combination with said first register means for clearing said determined line location number from said second register and for subsequently gating said defined line location number from said first register means into said second register means.

Claim 8

In a telephone system, the combination set forth in claim 6 wherein said enabling means further comprises means enabled by said logic means for directing said coupling means to couple said calling line to one of said storage locations addressed by said defined line location number.

Claim 9

In a telephone system, the combination set forth in claim 7 wherein said directing means comprises apparatus for transmitting said defined line location number from said second register means to said memory store.

Claim 10

In a telephone system a central office, lines connected to said central office wherein each said line is designated by a line location number, a memory store common to said lines and responsive to signals from said lines for storing information in storage locations addressable by said line location numbers, means responsive to a service request signal from a calling one of said lines for automatically recording the designated line location number of said calling line, means selectively connectable to said calling line for registering code numbers and line location numbers defined by signals transmitted from said calling line, means operatively responsive to said registering means in accordance with said defined line location number and a predetermined one of said code numbers for canceling the designated line location number recorded in said recording means and for substituting said defined line location number therefore, and means operative upon the substitution of said defined line location number for coupling said calling line to the memory storage location defined by said substituted line location number.

Claim 11

In a telephone system a central office, lines connected to said central office wherein each said line is designated by a line location number, a memory store common to said lines and responsive to signals from said lines for storing information in storage locations addressable by said line location numbers, means responsive to a service request signal from a calling one of said lines for automatically recording the designated line location number of said calling line, means selectively connectable to said calling line for registering code numbers and line location numbers defined by signals transmitted from said calling line, means operatively responsive to said registering means in accordance with said defined line location number and a predetermined one of said code numbers for canceling the designated line location number recorded in said recording means and for substituting said defined line location number therefore, and means operative upon the substitution of said defined line location number for coupling said calling line to the memory storage location defined by said substituted line location number.

Claim 12

In a telephone communication system a central office, lines connected to said central office wherein each said line is assigned a line location number and a class of service number the combination of which uniquely identifies said line, centralized memory storage equipment in said central office connectable to said lines for writing information signals transmitted from any said connected line into storage locations addressed by said line location numbers, first register means operatively responsive to a request signal from a calling one of said lines for recording the assigned line location number identifying said calling line, second register means selectively connectable to said calling line for recording additional signals defining line location numbers and code numbers dialed by said calling line, first relay means operatively responsive to said request signal for identifying the class of service number of said calling line, first logic means enabled by said first relay means in combination with the additional signals recorded in said second register means for detecting the recording of said code numbers and said line location number in said second register means, pulsing means enabled by said first logic means for canceling the assigned line location number recorded in said first register means, second logic means enabled by said first logic means for gating the dialed line location number recorded in said second register means into said first register means, second relay means enabled by said first logic means for ascertaining the completion of the registration of said dialed line location number in said first register means, third relay means enabled by said second relay means for connecting said calling line to said memory equipment, and means including make contacts of said third relay means for transferring said dialed line location number from said first register means to said memory equipment.

Claim 13

In a telephone communication system a central office, lines connected to said central office wherein each said line is assigned a line location number and a class of service number the combination of which uniquely identifies said line, centralized memory storage equipment in said central office connectable to said lines for writing information signals transmitted from any said connected line into storage locations addressed by said line location numbers, first register means operatively responsive to a request signal from a calling one of said lines for recording the assigned line location number identifying said calling line, second register means selectively connectable to said calling line for recording additional signals defining line location numbers and code numbers dialed by said calling line, first relay means operatively responsive to said request signal for identifying the class of service number of said calling line, first logic means enabled by said first relay means in combination with the additional signals recorded in said second register means for detecting the recording of said code numbers and said line location number in said second register means, pulsing means enabled by said first logic means for canceling the assigned line location number recorded in said first register means, second logic means enabled by said first logic means for gating the dialed line location number recorded in said second register means into said first register means, second relay means enabled by said first logic means for ascertaining the completion of the registration of said dialed line location number in said first register means, third relay means enabled by said second relay means for connecting said calling line to said memory equipment, and means including make contacts of said third relay means for transferring said dialed line location number from said first register means to said memory equipment.
