This is the local ^^^^^ part of the X.121 address so that is where they are
found. A address is definitely NOT a Mnemonic, you may USE a mnemonic
to remember a address, indeed that is what we do when we put names
in phone books, the name is mapped to the addresss.

Cut the rest and toss -----------------


Since we are on this, I will do a quick refersher of X.121 addressing.
The X.121 addresses or  International Data Number (IDN) are broken
down into 3 parts:
1. Digital Country Code or DCC (3 diigits)
2.Public Switched Network or PSN (1 digit)
  NOTE the combination of DCC and PSN gives us the
  Digital Network Id Code or DNIC, which in our case is 3100, more on
this later.
3. National Terminall Number or NTN, which may be up to 10 digits, this is the
number you will see in normal local operations.
For example a call to K4GBB will only need the use of hte NTN...

KP4DJT-8 (Commands = ?) : gbb
Trying NODE @ 3100,352726... Type <RETURN> to abort
*** Connected to NODE @ 3100,352726 (Escape: ~. )
You are connected  to the K4GBB FPAC Node
Located in Cedar Cove, Florida

FPAC shows the DNIC (3100) but when the call was set up I only used the
352726 part of the address.



As we interconnect the network with other countries, you will see the full
address being used,  Here is a example of a call to the switch over in Paris,
France off of my switch.
Trying NODE @ 2080,175502... Type <RETURN> to abort
*** Connected to NODE @ 2080,175502 (Escape: ~. )
Bienvenue sur la derniere version de Fpac !
Welcome to the last release of Fpac!

208 is the DNIC,
0 is the NTN
175502

In this case in order to set up the call I had to use the full IDN in order to
establish the call. FPAC Linux has a resolver that will allow callsigns to
be mapped to addresses when the system can do so.

What we are interested in locally is the last 6 digits of the address that is
what should show up in the data base.
