Call limit mode can be enabled (turned on) or disabled (turned off).
When call limit mode is on, the test set will not respond to any access probes from the access terminal (during events such as opening a session or connection, keep alive mechanisms etc.). This forces the access terminal to repeatedly send access probes.
