rCell 100 MTR-EV3 User Guide
Field Description
SIM Pin The pin used to unlock the SIM for use (only required if the SIM is locked).
This does not apply to CDMA radios.
APN The Access Point Name assigned by the wireless service provider (carrier
specific).
Init String# Optional fields to apply additional AT commands that execute just before
every PPP connection attempt. Use these fields to expand functionality and
to troubleshoot.
Authentication
Authentication Type The type of authentication to use when establishing a PPP connection:
NONE, PAP, CHAP, or PAP-CHAP (either). Authentication may not be
required by the cellular service provider.
Username Name of the user that the remote PPP peer uses to authenticate.
Password Password that the remote PPP peer uses to authenticate.
Keep Alive
1
Used to periodically check if the cellular link is up; if not, the device tries to establish the link.
ICMP/TCP Check
1
An active check that provides the most reliable and reactive diagnosis of the cellular link, but requires
sending data through the cellular link.
Enabled
1
Enables the Active Keep Alive check. Depending on the plan type and data
usage, this may result in additional data charges.
Keep Alive Type
1
Protocol type for active keep alive, either TCP or ICMP. ICMP periodically
pings the designated host at the specified interval. TCP tries to make a
connection to the designated host at the interval specified.
Interval
1
Time in seconds between active checking of the cellular link.
Hostname
1
Host name or IP address for the keep alive check.
TCP Port
1
TCP port number to connect with the TCP server (only visible when Keep
Alive Type TCP is selected).
ICMP Count
1
Number of sequential, unsuccessful ping attempts to the specified host to
declare that the link needs to be re-established (only visible when Keep Alive
Type ICMP is selected).
Data Receive Monitor
A passive check that observes the absence of packets received over a given amount of time. This check
cannot reliably determine if the link is down; no network traffic may cause the monitor to signal to
shutdown and re-establish the cellular link even though the link was in a good state.
Enabled Enable or disable the passive monitoring of the cellular link.
Window The amount of time that can pass without receiving network traffic before
the cellular link is torn down and re-established.
1
If you choose PPP-IP Passthrough and Serial Modem mode, this field is not available.
