Field Description
IP Compression Select whether compression is to be activated before data en-
cryption. If data is compressed effectively, this can result in
higher performance and a lower volume of data to be trans-
ferred. In the case of fast lines or data that cannot be com-
pressed, you are advised against using this option as the per-
formance can be significantly affected by the increased effort
during compression.
The function is enabled with ,.
The function is disabled by default.
Alive Check Select whether and how IPSec heartbeats are used.
A Teldat IPSec heartbeat is implemented to determine whether
or not a Security Association (SA) is still valid. This function
sends and receives signals every 5 seconds, depending on the
configuration. If these signals are not received after 20 seconds,
the SA is discarded as invalid.
Possible values:
• -3" (default value): Automatic detection of whether
the remote terminal is a Teldat device. If it is, ?#
* K<)" (for a remote terminal with Teldat) or 
" (for a remote terminal without Teldat) is set.
• ": Your device sends and expects no heartbeat. Set
this option if you use devices from other manufacturers.
• ?# <)" ,&: Your device expects a
heartbeat from the peer but does not send one itself.
• *: Your device expects no heartbeat from the peer, but
sends one itself.
• ?# * K<)": Your device expects a
heartbeat from the peer and sends one itself.

be propagated during phase 2.
