Chapter 9: Pre-Access Commands
What preaccess is:
Preaccess is a system used by several large linking sytsems to specify which controller in the
network a DTMF command is intended to go to. A common configuration would be to enter
the "*" key before commanding the local repeater, "#99" before commanding a distant
controller via a link, and "#98" before commanding a different controller on the linking system.
The advantage of requiring the user to "preaccess" a controller before commanding it is that
you can use the same command names on each controller without confusion as to which one
you are talking to. This is a very simplified description, but it should give you the idea.
What you need to know:
Because the preaccess system works quite differently from the way the RLC-Club normally
works, there is a lot involved with changing back and forth. Commands 070 and 071 have been
provided to make the conversion to preaccess easy and painless. If you have converted a port to
preaccess and want to change it back, use command 072.
You always configure one port at a time for preaccess, so you can set up one port for preaccess
and leave another port alone. This allows you to have a mixed system. This might be useful if
you want to try out preaccess on one port without forcing all of the users of a repeater on a
different port to change the way they do things. It also allows you to use the RLC-Club to
interface between linking systems that do things differently.
