I agree with Bob (surprise).  The format Bob is recommending does everything needed to identify an Echolink RF node to a mobile, quickly identify the node number, identify the Echolink's callsign without "ghosting" that station, and identify the insertion "station".  As far as status meaning, that would best be answered by K1RFD.

Note that since this is insertion into APRS-IS, the insertion station can use any 1 or 2 character SSID, and it does not have to be a callsign.  For instance, EMAIL, EMAIL-2, WHO-IS, CQSRVR, WXSVR, etc. denote specialty servers.  You could use ECHOSVR or ELINK, for instance (callsigns on APRS-IS are limited to a total of 9 characters including SSID).  Do not use E-LINK because LINK is not a valid SSID and E is not a valid callsign (LINK is more than 2 characters, E is only one character where at least 3 are required).

Hope this helps.
