9.1.4. Modem Mode
The Modem Mode provides features specifically related to modem communication. A
Modem Mode Port can perform all functions normally available in Any-to-Any Mode.
The Modem Mode is available at all TSM/RSM ports except the Network Port.
When a call is received, the unit will prompt the caller to enter a username and
password. The TSM/RSM allows three attempts to enter a valid username and
password. If a valid username and password is not entered within three attempts, or
if the user does not respond to the login prompt within 30 seconds, the modem will
disconnect.
