Welcome to dialup connections :) This is serial connections for you. WIthout more details it's impossible to tell whether the remote or local side are dropping packets, or (more likely) line noise is causing a retransmit in the modem. Considering the packet is eventually getting through, the modem is probably recovering from a dropped packet or interrupted line. 30s delays sounds like call waiting.
