We are in the closing phases of installing five more with one call

It is well to sort out "why".<br>
The root of the "requirement" is to *simplify* use of the AX.25
"connect" to a jnos node.<br>
Only for the AX.25 network.<br>
When the call is unique for the bbscall, <br>
==>then jnos responds to a connect request without requiring a
"prompting character".<br>
<br>
Using the idea "required" is an overstatement.<br>
Only ONE unique call is "REQUIRED" for all services on one jnos
incidence [node] <br>
BUT<br>
if the bbscall is not unique then the remote operator must enter a
character [usually a CR] to allow local jnos to resolve how to
respond to the request.<br>
<br>
Short answer:<br>
yes -- more than one.<br>
yes -- the SSID is the tool to give uniqueness to the call.<br>

Not really, but all [mycall, bbscall, ttycall, ETC] may have
[actually default to] one unique mycall with SSID [0-15].<br>
So one valid SSID scheme is:<br>
xx6xxx-0 home "all calls"<br>
xx6xxx-1 car "all calls"<br>
xx6xxx-2 truck "all calls"<br>
xx6xxx-3 boat "all calls"<br>
xx6xxx-4 hill-top somewhere "all calls"<br>
=>until you run out of SSIDs and it requires the ol' CR to get
going<br>
<br>
Another is:<br>
xx6xxx-0 home mycall<br>
xx6xxx-2 car mycall<br>
xx6xxx-4 truck mycall<br>
xx6xxx-6 boat mycall<br>
xx6xxx-8 hill-top somewhere mycall<br>
xx6xxx-1 home bbscall<br>
xx6xxx-3 car bbscall<br>
xx6xxx-5 truck bbscall<br>
xx6xxx-7 boat bbscall<br>
xx6xxx-9 hill-top somewhere bbscall<br>
==>you get 1/2 the number of rigs because you run out of SSIDs
sooner but no cr is needed.<br>
<br>
There is NO STANDARD for SSID assignment.<br>
Some have gone very OVERBOARD in setting SSID recommendations --
read with a skeptical eye.<br>
More importantly -- have fun!<br>
