Based on years of customers experience for different applications, besides SNMP, DDNS,
H8959-4GSPT Cellular router has developed many functions for wireless network equipment,
such as ICMP check, interface flow check function, M2M terminal management function, task
management function and waking on demand function.

ICMP check
There is fake link (can get IP after dialing, but cannot link to destination address). Usually
LCP is used to avoid this. Besides LCP, H8959-4GSPT Cellular router can use another more
reliable checking way ICMP which check the link by PING. When abnormal link is checked,
the preset action will be executed to recover the link and systems quickly. Initially ICMP is to
check wireless link, and now it can be used to check VPN link and supports simultaneous
check in different rules. It supports maximum 10 ICMP check rules.
