Abstract

Interactive subscriber telephone terminals have a display screen and softkeys which are controlled by management software. The management software may be downloaded from a remote server to control the display and softkeys. Different techniques for achieving this download are described. In one case each subscriber terminal has a memory in which can be preloaded a list of one or more Calling Line ID numbers corresponding to the telephone number of a server(s). If a server dials the subscriber terminal the calling line ID is compared with the list and, if there is a match, the terminal immediately goes off-hook and follows the protocol for a Server Initiated Download. In an alternative case each subscriber terminal is capable of calling out to predetermined server lines to obtain the ADSI scripts. This dial out of stored telephone numbers may be done on an automatic timed basis or may be initiated by a server calling a pager embedded in the subscriber terminal.

Claims

1. An interactive subscriber telephone terminal, comprising:

a display screen,

a plurality of temporarily definable response/data entry keys; and

local control means for selectively causing said display screen or said response/data entry keys to be controlled by one of;

remote signals transmitted to the terminal from a telephone switching office, and said local control means, the terminal further comprising;

means for selectively storing one or more telephone numbers of one or more remote servers, respectively; and

means for automatically dialling out from the terminal at predetermined times the one or more stored telephone numbers whereby download of management software to the terminal from a remote server is achieved.

2. A terminal according to claim 1 in which the means for selectively storing one or more telephone numbers is a NVRAM which also stores the predetermined times associated with each telephone number.

3. A terminal according to claim 2 in which the NVRAM is programmable by a command from a remote server to add, delete or change the one or more telephone numbers and associated predetermined times stored in the NVRAM.

4. A terminal according to claim 2 in which the NVRAM has been factory preprogrammed with the one or more telephone numbers and associated predetermined times stored therein.

5. A terminal according to claim 2 in which the NVRAM is programmable at the terminal by a subscriber to add, delete or change the one or more telephone numbers and associated predetermined times stored in the NVRAM.

6. An interactive subscriber telephone terminal, comprising:

a display screen,

a plurality of temporarily definable response/data entry keys; and

local control means for selectively causing said display screen or said response/data entry keys to be controlled by one of;

remote signals transmitted to the terminal from a telephone switching office, and said local control means, the terminal further comprising;

a pager means for receiving from a paging service radio messages each including a telephone number entered by a calling party via the telephone switching office; and

means for comparing each received telephone number with the stored one or more telephone numbers; and

means for dialling out from the terminal one of the one or more stored telephone numbers when a match is made with a received telephone number whereby download of management software to the terminal from a remote server is achieved.

7. A terminal according to claim 6 in which the means for selectively storing one or more telephone numbers is a NVRAM.

8. A terminal according to claim 7 in which the NVRAM is programmable by a command from a remote server to add, delete or change the one or more telephone numbers stored in the NVRAM.

9. A terminal according to claim 7 in which the NVRAM has been factory preprogrammed with the one or more telephone numbers stored therein.

10. A terminal according to claim 7 in which the NVRAM is programmable at the terminal by a subscriber to add, delete or change the one or more telephone numbers stored in the NVRAM.

11. A method of downloading management software from a remote server through a telephone network to an interactive subscriber telephone terminal which has a display screen, a plurality of temporary definable response/data entry keys and local control means, the method comprising:

the subscriber terminal dialling automatically the telephone number of the remote server at predetermines times; and

downloading from the remote server the management software when connection between the remote server and the subscriber telephone terminal is established.

12. A method according to claim 11, wherein the subscriber telephone terminal stores a plurality of remote server telephone numbers and associated predetermined times and the subscriber telephone terminal dials automatically all of the server telephone numbers at the associated predetermined times whereby each remote server downloads management software when connection between that remote server and the subscriber telephone terminal is established.

13. A method of downloading management software from a remote server through a telephone network to an interactive subscriber telephone terminal which has a display screen, a plurality of temporary definable response/data entry keys and local control means, the method comprising:

the server dialling a telephone number of a paging service of the subscriber and entering the server telephone number;

the paging service transmitting by radio the server telephone number which is received in a pager embedded in the subscriber telephone terminal; and

comparing the received telephone number with one or more telephone numbers stored in the subscriber telephone terminal;

if a match between the received telephone number and the one or more telephone numbers is made causing the subscriber terminal to dial out the matched telephone number; and

downloading from the remote server the management software when connection between the remote server and the subscriber terminal is established.
