To: allow the user tq monitor the ADS, modem. Modem States ETE The Modem Icon consists: of two lights side by side: These lights are used to display the state of the modem. The left light signifies data is being transmitted whereas the right light signifies information. is ‘being. received.
Placing the mouse cursor on the Modem Icon will show a summary of the modems status by displaying the modem's state, upstream line rate and downstream line rate. Monitoring the ADS Modem ADS Test Application Pointing to the Modem Icon, and clicking on the: left-mouse button will display the ADS Test Application window. From this windows, the user will be able to run Diagnostics, review the ADS modem status and view the ATM/ ADS Statistics.
Modem Con Menu Pointing to the Modem Icon and clicking on the right mouse button will display the Modem Icon options window. from this window, the user will be able to: a. "Disconnect” the modem from or "Connect" the modem to. the ‘central . office equipment; b.Run a diagnostic test to test the modem; ¢. Monitor the ADS modem status; d. Monitor various. ADS. statistics; e. configure the PVC” values For REC1577 and RECTAL, Connecting and. Disconnecting the ADS.
ADS State displays the current status of the modem. These states are: Connected, Connecting, and Disconnected. Protocol The protocol section displays which ADS standard is being used. Transmit / Receive Rate In the Transmit and Receive section, the user will be able to see what kind of line rate is being achieved for both upstream and downstream line rates. ADS Statistics Menu From this menu, the user will be able to see: Error Count Information, ATM Transmission statistics and ATM Receive statistics.
ATM Transmission Side Statistics displays the number of packets transmitted. ATM Receive Side Statistics displays the number of good and bad packets received. Configuration Menu The Configuration menu will allow the user to check or change the ADS network modems PVC values for RFC1577 and RFCI483. To change the PVC values, simply select one of the RFC protocols, enter the VPI and VCI values, and then click on the PVC Setting button. Click Yes when asked to reboot the system.
