„ Bridged with Serial:
When this type selected, the MB5000 acts as a modem
between the cellular network and the serial port. You can attach a DTE device
such as Cisco router or PC with the serial cable, and then initiate a PPP
procedure on the client device.
Note:
MB5000 can connect the 3G modem automatically when received a PPP
connection request from a DTE device and disconnect it when received a PPP
termination. This mode also support auto disconnect like dial on demand. Make sure
the MB5000’s serial speed is match with the modem. (refer to “3.4.1.1
administration“ of this guide for the detail about how to set the serial speed)
z Keepalive: This can detect whether the WWAN connection is in good status. When
the WWAN connection is abnormal, keepalive module will detect it if keepalive is
enabled and the router will try to reconnect automatically. When the system is still
abnormal, modem will be restart. After consecutively restart for several (configurable)
times, if the system still could not turn well, the router will reboot automatically. Check
the box to enable the Keep-Alive feature. If the Keep-Alive is enabled, MB5000 will
detect the Internet connection health periodically with the interval specified. Once it
detects the Internet connection goes down, it will try to connect again. It will try to
re-connect several times (3 times by default). If all of the attempts fail, MB5000 will
reset the 3G data card modem. If still no help, MB5000 will reboot itself after several
attempts (3 times by default) fail.
