Abstract

Modems are apparatus located at the ends of communication links to perform data communication between terminals (Data Transmission Equipment (DTE)) and/or central processing units (CPUs). Depending upon the application, the modems can be connected as point-to-point or multipoint configurations to leased lines or switched networks. The initial network configuration is usually performed at modem installation, via option switches that personalize the modem. The dynamic setting of the modem parameters by the attached control unit, or remotely through the communication line, allows both an initial and "on line" configuration. The dynamic setting would even allow a momentary definition of the modem behavior to satisfy traffic requirements.

Dynamic Setting of Modem Parameters

Modems are apparatus located at the ends of communication links to perform data communication between terminals (Data Transmission Equipment (DTE)) and/or central processing units (CPUs). Depending upon the application, the modems can be connected as point-to-point or multipoint configurations to leased lines or switched networks. The initial network configuration is usually performed at modem installation, via option switches that personalize the modem. The dynamic setting of the modem parameters by the attached control unit, or remotely through the communication line, allows both an initial and "on line" configuration. The dynamic setting would even allow a momentary definition of the modem behavior to satisfy traffic requirements. As an example, a tributary multi-point modem may momentarily be specified as a point-to- point modem with continuous carrier mode, for batch processing purposes or with the anti-streaming option disabled.

Methods have been described for performing network management or test operations via the central unit. Remote information is collected through the communication link using service speed or backward channel specific commands. The collected information is then assembled, analyzed, and checked for validity. The same method and equipment may be used for dynamically setting the modem parameters. The modems provided with non-volatile random- access memory (NVRAM), store the modem parameters. These parameters will be made accessible to the CPU, through the network management procedure, for both read and write operations. A command message may thus be sent onto the line...
