When the Gateway power fails, calls on Line 4 are routed to the Bypass line. Calls can be made or received using a regular
analog phone. When the Gateway recovers, the bypass is disabled so that this line cannot be used to eavesdrop on other
calls.
The DHCP server assigns the Gateway an IP address. If there is no DHCP server present, the Gateway assigns itself an IP
address (self-assigned link-local address).
The Gateway's PSTN lines are assigned as line 1 to 4. If a second Gateway is connected to the network, it is assigned
lines 5 to 8. Up to four Gateways can be connected, providing up to 16 PSTN lines.
