  • Patent number: 5663982
    Abstract: A first terminal (10) and a subscriber analog modem (20), operating at a data rate D, cause a modem pool analog modem (30), a modem pool digital modem (40), a subscriber digital modem (50), and a second terminal (60) to adjust their data rates to D. The two analog modems connect and then train, the modem pool analog modem thus adjusting its data rate to D. The two digital modems connect and then train, thus establishing an initial digital modem data rate. The modem pool analog modem sends D to the modem pool digital modem. The modem pool digital modem then sends D to the second terminal which, in turn, adjusts its data rate to D. The modem pool digital modem adjusts its data rate to D. The digital modems then re-train, thus causing the subscriber digital modem to adjust its data rate to D.
