5.0 Network Topologies
5.4 Everyone-to-Everyone (E2E)
E2E mode is used for communications between all remote modems,
i.e. data from every modem is broadcast to every other modem in the network.
Considering the amount of data re-broadcasting (via the Master), it is a very bandwidth-
intensive network topology.
There are no specific factory default settings to configure modems for E2E operation.
To establish a basic E2E network:
Master
•
enter into Command Mode
•
load the &F1 factory default settings
•
change the Network Type (S133) to 2
•
change Packet Retransmissions (S113) from 5 to 0 (increase from 0 if re-
quired)
•
save the change using the AT&W command
•
go online with the ATA command
Slaves
•
enter into Command Mode
•
load the &F2 factory default settings
•
change the Network Type (S133) to 2
•
change the Unit Address (S105) to a unique number (range: 2-65534)
•
change the Destination Address to 65535 (the broadcast address)
•
save the change using the AT&W command
•
go online with the ATA command
An E2E network
requires a Master
modem.
The data being
transmitted from
remote units in an E2E
network travels to the
Master and is then re-
broadcast to all other
remotes.
