Before you retry dialing, push a hook key over than 1.6 seconds and watch the tel lamp of the cable modem has gone out. When connecting the NTT circuit with a cable modem and talking over the telephone by the NTT circuit side , on hook takes about 1.6 seconds until a telephone call goes out similarly. But if the modem is power off, it goes out in about 0.1 seconds.
