Parameters
<cnx cnf> 1 – 5 (PDP context configuration) a numeric parameter which specifies a
particular PDP context configuration
<tim1> 1 – 120s (default value = 30s) If module fails to activate the PDP context, a
timer of <tim1> will be started. When this timer expires, it will try to activate the PDP context
again.
<nbtrial> Attempt times from1 – 4 (default value = 2) Module will try to activate the PDP
context with max <nbtrial>
<tim2> 0 – 300s (default value = 60s)
0 Deactivated (connection will not close by itself)
For client sockets, module will try to connect to the server within <tim2>s; if <tim2> expires,
it will give up the connection.
<idletime> 0 – 1800s (default value = 30s) When all sessions are closed, the idle timer
starts with the idle time. When this timer expires, it will try to deactivate the PDP context.

reused.
