Abstract
Abstract A method for remotely configuring a modem in a communication system is described herein. Specifically, the method allows a modem user the ability to modify or view the options of a remote modem by placing the remote modem first into a test mode. The method, following the execution of the test mode, provides some security through the use of a security code which is programmable by the remote user. The remote modem is then placed into a reconfiguration mode, after which the local modem transmit commands to the remote modem using a bi-sync protocol to ensure accurate reception of commands and responses. The process of remote configuration is terminated by exiting the reconfiguration and test modes.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
127 words
In a communications system having at least a first and a second modem , a method selectively operable by a user for remotely configuring a modem without using a tertiary channel, said method comprising the steps of: using said first modem to place said second modem in a test mode via a main channel; transmitting from said first modem via said main channel, following said test mode placement step, a predetermined coded signal identifiable by said second modem primarily causing said second modem to change from said test mode to a reconfiguration mode; configuring said second modem following identification of said coded signal via at least one signal from said first modem; and using said first modem to move said second modem out of said reconfigure mode.
Claim 2
Dependent Claim
127 words
In a communications system having at least a first and a second modem , a method selectively operable by a user for remotely configuring a modem without using a tertiary channel, said method comprising the steps of: using said first modem to place said second modem in a test mode via a main channel; transmitting from said first modem via said main channel, following said test mode placement step, a predetermined coded signal identifiable by said second modem primarily causing said second modem to change from said test mode to a reconfiguration mode; configuring said second modem following identification of said coded signal via at least one signal from said first modem; and using said first modem to move said second modem out of said reconfigure mode.
Claim 3
Dependent Claim
42 words
The method according to claim 1 wherein said method further includes the step of: receiving an acknowledgment from said second modem that said coded signal has been identified and that said second modem is in said reconfiguration mode after said transmitting step.
Claim 4
Dependent Claim
40 words
The method according to claim 1 wherein said method further includes the steps of: removing said second modem from test mode after said step of transmitting said coded signal when said coded signal is not identified by said second modem.
Claim 5
Dependent Claim
47 words
The method according to claim 1 further comprising the step of said first modem configuring said second modem only upon receipt of a predetermined acknowledge signal from said second modem in response to said second modem receiving a predetermined remote configuration code (RCC) from said first modem.
Claim 6
Dependent Claim
104 words
A modem for remotely configuring another modem in a communication system utilizing a main channel, said modem comprising: means selectable by a user for generating a signal for remotely placing said other modem in a said test mode; means for transmitting via said main channel a predetermined coded signal identifiable by said other modem causing said other modem to change from said test mode to a reconfiguration mode; means for generating a configuring signal for said other modem following identification of said coded signal by said other modem; and means for generating a signal for moving said other modem out of said reconfiguration mode.
Claim 7
Dependent Claim
104 words
A modem for remotely configuring another modem in a communication system utilizing a main channel, said modem comprising: means selectable by a user for generating a signal for remotely placing said other modem in a said test mode; means for transmitting via said main channel a predetermined coded signal identifiable by said other modem causing said other modem to change from said test mode to a reconfiguration mode; means for generating a configuring signal for said other modem following identification of said coded signal by said other modem; and means for generating a signal for moving said other modem out of said reconfiguration mode.
Claim 8
Dependent Claim
88 words
A remotely configurable modem for use in a communications system that uses a main channel and has another modem, said modem comprising: means for receiving a signal over said main channel from said another modem placing said configurable modem in a test mode; means for identifying a predetermined coded signal sent from said another modem which causes said configurable modem to switch to a reconfiguration mode; means for receiving configuring signals over said main channel from said another modem moving said configurable modem out of said reconfiguration mode.
Claim 9
Dependent Claim
88 words
A remotely configurable modem for use in a communications system that uses a main channel and has another modem, said modem comprising: means for receiving a signal over said main channel from said another modem placing said configurable modem in a test mode; means for identifying a predetermined coded signal sent from said another modem which causes said configurable modem to switch to a reconfiguration mode; means for receiving configuring signals over said main channel from said another modem moving said configurable modem out of said reconfiguration mode.
Claim 10
Dependent Claim
31 words
The modem according to claim 5 wherein said configuration signal generating means comprises means for generating a user selectable command code that corresponds to a modifiable function of said another modem.
Claim 11
Dependent Claim
28 words
The modem according to claim 6 wherein said configuration signals comprise at least one user selected command code that corresponds to a modifiable function in said configurable modem.
Claim 12
Dependent Claim
34 words
The method according to claim 1 wherein said using step includes said first modem transmitting a command to said second modem that causes said second modem to enter a remote digital loop (RDL) mode.
Claim 13
Dependent Claim
40 words
The method according to claim 2 further comprising the step of aborting the reconfiguration of said second modem if said first modem does not receive said acknowledgement within a predetermined window of time following the end of said transmitting step.
Claim 14
Dependent Claim
21 words
The modem according to claim 5 wherein said user selectable means comprises means for generating a remote digital loop (RDL) signal.
Claim 15
Dependent Claim
35 words
The modem according to claim 5 further comprising means for aborting said reconfiguration if said modem does not receive an acknowledgement signal within a predetermined window of time following the transmission of said coded signal.
Claim 16
Dependent Claim
17 words
The modem according to claim 6 wherein said test mode comprises a remote digital loop (RDL) mode.
Claim 17
Dependent Claim
40 words
The modem according to claim 6 further comprising means for aborting said reconfiguration if said configurable modem does not transmit over said main channel an acknowledgement signal within a predetermined window of time following the reception of said coded signal.
