-----------------------------

Since many TNCs now support multiple AX25 connections,you
may wish to establish multiple simultaneous uplinks to your
local node. This can be donne successfuly, but somme precaution
are in order. The AX25 protocol is not capable of supporting
multiple simultaneous connections in wich both originator
and destination callsigns are identical. Consently, to achieve
multiple concurrent uplink from your TNC to a node, you must 
employ the following tactics:

1) If your TNC is capable of supporting independent originator
callsign ("MYCALL") on each channel, the you can establish
different callsigns for each channel (typically, your call with
SSIDs -0 -1 -2 etc.) and then uplink with impunity.

2) If your local node (let's say it's "ON4HU-1") has a mnemonic
identifier (let's say it's "MOUS1"), then the node will respond
to two different names:
example: C ON4HU-1
         C MOUS1

3) en moore...again the node respond with 17 different names
its callsign (ON4HU-1) plus its identifier with any valid SSID
Example: C MOUS1-0
           MOUS1-1
           MOUS1-2
           MOUS1-3
           ...
           MOUS1-15

Cosequently, you can establish multiple connect to a node as long as
you are careful to call the node by a different name when establih-
ing each uplink.

NOTE:  This is only valid on a node using identifier, this
       possibility do not exist for the other.
