Figure 16: Point-to-point network with repeater
The following should be noted for the point-to-point network with repeaters:
All units in the network have „Repeaters in network‟ set to 1.
The main port protocol on the repeater is set to Hayes even though the main port is not used. This is
so the unit is in packet driven mode rather than data driven mode (see section 5).
Routing tables need to be set on the base and remote radio modems.
Other configuration parameters which may help in fine tuning the system operation are:
Rx packetiser timers. See page 18 for more information.
Max packet size.
Singlecast retries. See page 24 for more information.
