Data Communication and Host Modes
Data usage using Keepalive
Keepalive is an optional feature. If you frequently pass data with your modem, you most likely do
not need to have Keepalive enabled. When using Keepalive, be aware that a ping moves approxi-
mately 66 bytes of data over the network and is billable by the
carrier. The following *IPPING
settings will incur approximate monthly data usage in addition to any other data usage:
Caution: If *IPPINGADDR is left blank or is set to an invalid IP address (example,
an IP which is unreachable or one which is not a valid IP address), modem perfor-
mance will be adversely affected.
