DCD Change
The DCD (Data Carrier Detect) signal has changed, also indicating that the modem
connection status has changed. For example, a DCD change to high also means
"Connected" between local modem and remote modem. If the DCD signal changes to
low, it also means that the connection line is down. When the DCD signal changes,
the EKI-1528/1526 will send an e-mail, or send a SNMP trap.
DSR Change
The DSR (Data Set Ready) signal has changed, also indicating that the data commu-
nication equipment's power is off. For example, a DSR change to high also means
that the DCE is powered ON. If the DSR signal changes to low, it also means that the
DCE is powered off. When the DSR signal changes, the EKI-1528/1526 will send an
e-mail, or send a SNMP trap.
