P-660R-F1 Support Notes

We can apply the schedule to the remote node in CLI by the commands:

wan node index []index#]

wan node callsch [index#]

wan node save

For example, if we want to apply the call schedule set 1 to remote node 1, we

could use the commands:

wan node index 1

wan node callsch 1

wan node save

 Time Service in P-660R-F1

There is no RTC (Real-Time Clock) chip so the P-660R-F1 should launch a

mechanism to get current time and date from external server in boot time. Time

service is implemented by the Daytime protocol(RFC-867), Time

protocol(RFC-868), and NTP protocol(RFC-1305). You have to assign an IP

address of a time server and then, the P-660R-F1 will get the date, time, and

time-zone information from this server. You can configure it in Web Configurator,

Advanced Setup, Maintenance -> System -> Time Setting.

12. Using IP Multicast

What is IP Multicast?

Traditionally, IP packets are transmitted in two ways - unicast or broadcast.

Multicast is a third way to deliver IP packets to a group of hosts. Host groups are

identified by class D IP addresses, i.e., those with "1110" as their higher-order

bits. In dotted decimal notation, host group addresses range from 224.0.0.0 to

239.255.255.255. Among them, 224.0.0.1 is assigned to the permanent IP hosts

group, and 224.0.0.2 is assigned to the multicast routers group.

IGMP (Internet Group Management Protocol) is the protocol used to support
