3.4.2.2 Exiting the Remote Connection
After completing the diagnostic session, the remote connection must be terminated.
Follow these procedures:
1. Complete or abort any operation currently under way.
2. Under EXIT, select the appropriate method of exiting.
Unless otherwise specified, always exit with a soft reset. Click on the Exit
with Reset button.
NOTE:
Resetting the system before exiting leaves the Avantra in a
known (idle) state. This helps to avoid confusion and pos-
sible problems to the customer later.
3. After transmitting the reset {MXRE} command to the Avantra, the program
issues a hang-up command to the modem. Make sure that the carrier detect
LED goes out, signaling that the connection has been terminated.
4. Call the customer site on the voice line to inform them that the Avantra is
back on line.
