Counting the Call Events

The following events are counted for each incoming call on a channel:
Table 7 Call Event Descriptions
Event Description
SEIZE This message from a WAN module to a WAN manager
process on the main processor indicates that the central
office switch has sent a channelized T1/E1 seize event.
RING This message from a WAN module to a WAN manager
process on the main processor indicates that a call has
arrived.
Modem/device assignment (start of session)
CONNECT This message from the WAN module to the WAN
manager process means that the RAC has accepted the
call and the WAN module and the CO have agreed that
the call has been established.
Chat This process tells the modem to answer and waits for
process DCD.
DCD The modem has connected successfully with the remote
assertion modem.
Modems count only three of these events: modem assignment, the chat
process, and DCD assertion.
For non-modem calls, the chat process and DCD assertion are not counted
or don't occur at all. The call is considered to be successful once a device
has been assigned.
The table below shows some possible causes for counts which are less
than that of their preceding event:
