4.3 TCP Server
When the GPRS DTU works as a TCP server, note that:
The DTU must have a fixed IP address. That is, the wireless DDN private network
service is required.
The DTU detects link availability by monitoring the wireless side data. If there is no data
from the wireless side in two hours (this interval cannot be set), GPRS disconnects the
PPP link and redials.
