Anytime you are paging an alphanumeric pager, you are the alphapager protocol. You can think of the alphapager protocol as being tunneled over LRSS and LRSN. For simple paging, you can probably get away with never reading it. However, when you start wanting to change alert modes, configure the pager, or use any other advanced functionality (e.g. group paging, countdown timer, etc.) you'll need to look at the alphapager protocol documentation.
LRSN is an XML based protocol over TCP.
