These are ECHOlink nodes.  Their frequency and PL.
Putting them on the APRS-IS is the first step in implementing 
"AVRS" (automatic Voice Relay System) which allows an 
APRS  mobile to establish a VOICE link to any other APRS 
user on the planet by simply sending an APRS "connect" 
request to the callsign he wants to converse with...

See:  http://www.ew.usna.edu/~bruninga/avrs.html 

The "AVRS" server sees the connect request message,
and handles it from there.  Sending back to the CALLER 
and to the CALLEE an object showing them their nearest
nodes and the freq and tone letting them know that 
both are currently available and giving them the DTMF
numbers to dial to establish the connection.

One change we have noticed is that we want the object
name to include the ECHOlink or IRLP node number so
that it is more useful to the end APRS user...
