Speed calling control and store

Claim 2

In a private automatic branch exchange, a control and store arrangement capable of providing signals representing a full multi-digit number in response to receipt of an abbreviated number formed of first and second digit signals, comprising: storage means including a plurality of individual number stores each capable of storing a plurality of multi-digit numbers in a respective one of a plurality of storage locations therein, and store control means responsive to said first digit signal of said abbreviated number for accessing a particular one of said individual number stores allocated to said first digit and responsive to said second digit signal for accessing a particular one of said plurality of storage locations in said accessed number store allocated to said second digit.

Claim 3

Claim 4

The combination defined in claim 2, wherein two individual values of said first digit designate said other one of said number stores, said store control means including steering means for accessing one or the other number in a storage location of said other one of said number stores in response to detection of one or the other value of said first digit.

Claim 5

The combination defined in claim 2, wherein each of said number stores includes a matrix of horizontal and vertical lines having the cross-points interconnected through diodes to strapping terminals, the strapping terminals along each horizontal line being capable of connection to output lines in a decimal combination representing a multi-digit number.

Claim 6

The combination defined in claim 4, wherein said number stores each further include input gating meAns for applying a first voltage to a selected horizontal line of the matrix in accordance with the value of said second digit, so that upon receipt of said abbreviated number said first voltage will be applied to the input gating means on one corresponding horizontal line in each number store.

Claim 7

The combination defined in claim 5, wherein said input gating means in each number store is normally inhibited, and each number store further includes means responsive to a respective value of said first digit for enabling the input gating means in only that one number store, so that only the storage location in the number store identified by said first and second digits is accessed.

Claim 8

The combination defined in claim 6, wherein said store control means includes scanning means for sequentially scanning the vertical matrix lines in each of said numbers stores.

Claim 9

In a private automatic branch exchange, a control and store arrangement capable of providing a full multi-digit number in response to receipt of an abbreviated number formed of first and second digits, comprising: storage means including a plurality of number stores for storing a plurality of multi-digit numbers in respective storage locations, each number store including a matrix comprising m storage locations each accommodating one n digit number or two numbers of n/2 digits, store control means responsive to said first digit of said abbreviated number for accessing a particular number store and responsive to said second digit for accessing a particular storage location in said number stores, including steering means for directing the storage and readout of two n/2 digit numbers in each storage location, and selectively actuatable means in each number store for inhibiting said steering means in connection with that number store.

Claim 10

In a private automatic branch exchange, a control and store arrangement capable of providing a full multi-digit number in response to receipt of an abbreviated number formed of first and second digits, comprising: storage means including a plurality of number stores for storing a plurality of multi-digit numbers in respective storage locations, each number store including a matrix comprising m storage locations each accommodating one n digit number or two numbers of n/2 digits, store control means responsive to said first digit of said abbreviated number for accessing a particular number store and responsive to said second digit for accessing a particular storage location in said number stores, including steering means for directing the storage and readout of two n/2 digit numbers in each storage location, and selectively actuatable means in each number store for inhibiting said steering means in connection with that number store.

Claim 11

The combination defined in claim 8, wherein two individual values of said first digit designate each respective number store, said steering means being responsive to one value to effect readout and storage of one number in a storage location and responsive to the other value to effect readout and storage of the other number in that storage location.

Claim 12

The combination defined in claim 8, wherein each matrix comprises m horizontal lines and n vertical lines having the cross-points interconnected through diodes to strapping terminals, the strapping terminals along each horizontal line being capable of connection to output lines in a decimal combination representing a multi-digit number.

Claim 13

The combination defined in claim 10, wherein said number stores each further include input gating means for applying a first voltage to a selected horizontal line of the matrix in accordance with the value of said second digit, so that upon receipt of said abbreviated number said first voltage will be applied to the input gating means on one corresponding horizontal line in each number store.

Claim 14

The combination defined in claim 11, wherein said input gating means in each number store is normally inhibited, and each number store further includes means responsive to a respective value of said first digit for enabling the input gating means in only that one number store, so that only the storage location in the number store identified by said first and second digits is accessed.

Claim 15

The combination defined in claim 12, wherein said store control means includes scanning means for sequentially scanning the vertical matrix lines in each of said number stores.

Claim 16

The combination defined in claim 13, wherein a different odd and even value of said first digit of said abbreviated number is applied to each number store, said selectively actuatable means including control gate means for passing one of said values of said first digit to enable said input gating means and manually settable means for inhibiting said control gate means.

Claim 17

The combination defined in claim 14, wherein said steering means is responsive to the odd or even value of said firSt digit for controlling said scanning means to scan vertical lines 1 through n/2 or vertical lines n/2 + 1 through n, respectively, in each matrix.

Claim 18

The combination defined in claim 15, wherein said steering means is responsive to the inhibited condition of said control gate means for actuating said scanning means to scan all n vertical lines in each matrix.
