1. “Register to network” and “Establish PPP with ISP” are two steps for establishing connection with the ISP.
2. If GuaranLink determines that the OnCell cannot establish connection with the ISP, it reboots the OnCell in
order to allow the OnCell to retry the connection once rebooted.
Common Settings
GuaranLink (default=Disable): Enable this setting to start the GuaranLink function.
Register to network timeout (min) (default=10): This setting is to specify how long GuaranLink
should wait to register to the network before the OnCell reboots itself.
PPP retry count (default=3 mins) This setting is to specify how many times GuaranLink should retry to
establish PPP with the ISP before OnCell reboots itself.
DNS/Ping remote host 1 and DNS/Ping remote host 2: This setting is for Cellular connection alive
checkand Packet-level connection check.” It specifies the target host of the DNS lookup and Ping
action. It could be either a domain name or an IP address.
GuaranLink Check Settings
ISP initial connection check (default=Disable): This function is to ensure that the OnCell can establish
connection with an ISP after it reboots.
Cellular connection alive check (default=Disable): Some ISPs may disable the connection if there is
no data transmitted in a specific period of time, depending on the ISP’s settings. This function ensures that
the cellular connection will be kept alive even if no data is transmitted for a period of time by performing the
check action of DNS lookup or ping action of DNS/Ping remote host 1 or DNS/Ping remote host 2. If the
check action fails after the retry count number specified in “Cellular connection alive check retry count”, the
OnCell will re-establish a connection with the ISP.
Cellular connection alive check interval (min) (default=5 min): This setting specifies the idle time
before GuaranLink performs the check action.
Cellular connection alive check retry count (default=3 sec): This setting specifies the number of
attempts to reach the remote target(s) before the OnCell re-establishes a connection.
Packet-level connection check (default=Disable): This function checks if the cellular network can be
accessed by performing the check action of lookup DNS or ping action of DNS/Ping remote host 1 or
DNS/Ping remote host 2. If the check action fails after the retry count number specified in “Packet-level
connection check retry count.the OnCell will re-establish a connection with ISP.
