This section describes how to set Menu-7 Alarms I and Menu-8 Alarms II.
How Alarms Are Reported
The DSU/CSU always reports all alarm conditions to:
¥ The device connected to its Comm Port (such as a terminal, printer or modem)
¥ The device connected to the remote DSU/CSUÕs Comm Port if Connection is set to
FDL (in Menu-8 Alarm II on the local DSU/CSU)
If a modem is connected, the DSU/CSU causes the modem to dial out (if in Menu-7
Alarm I, alarms are Enabled and Block all Alarms is set to No and in Menu-8 Alarm II,
Connection is set to Modem and valid telephone numbers are set in Phone Number 1
or Phone Number 2).
