.TC<sec> = Tunnel Connect Timeout (default 22 seconds)
This timeout is used when the V-Tap ISDN tries to connect to the
Tunnel server. The default 22 seconds is enough to send 4 requests. If
no reply comes from the remote side within the timeout, the V-Tap
starts trying again after a few seconds with a new source port
number (see above). Storage onto SD card just continues and is not
interrupted by any connection or disconnection of the Tunnel.
.TI<sec> = Tunnel Idle Timeout (def 0 = always connected)
This timeout is used to disconnect the active tunnel connection, only
when no packets are received (sniffed) anymore from the local
connected network. Default, the idle timeout is disabled and the
tunnel stays connected forever.
.TK<sec> = Tunnel Keep-alive Timer (default 60 seconds)
This timer is used to keep the connection alive between the V-Tap
and the Tunnel server. Default, a dummy TCP packet is sent every 60
seconds by the V-Tap to the server.
.LX<size> = Maximum Data Size in packets (default 1024)
This sets the maximum length of the data portion inside all
communicated packets on the network for Tunnel, FTP and Web.
The length excludes the Ethernet, IP and TCP headers, which are 54
bytes together. The maximum length of any packet on the network
can be 1514 bytes, so that leaves max 1460 bytes for the data part.
The default length is based on optimal performance when sending
data from an SD card.
When sending directly on a WAN or very busy LAN, the length might
be decreased for better performance (try .LX512).
.LS<num> = LAN System Service Timer (default 18 = fastest)
The default value is for fastest network speed. When a lot of V-Tap
units are sending to the same Tunnel server, it might be better to
lower the speed to prevent an overload of streams.
The values 65 and 1 can be used for slow and slower sending.
The values 50 and 18 (same as 0) can be used for faster sending.
NOTE: When using the RTR Call Monitoring Software for the PC, the
LAN Service Timer must be set to 1 to get a constant audio stream.
