InOctets and OutOctets show the number of bytes received by the answering device and
transmitted by the calling device, respectively.
Note:
When an ISDN call disconnects from either a German 1TR6 switch or a Japanese NTT
switch, the switch sends call billing information to the call originator as part of the call
tear-down process. This information is written to the eventCallCharge (eventEntry 17) SNMP
object in the Ascend Enterprise MIB events group (10). An SNMP manager can then read this
object to determine the cost of the call. The eventCallCharge object is a read-only integer and
is applicable only if eventType is
callCleared (3)
. Otherwise, 0 is returned.
For more information, see Chapter 5, “Administering E1 and T1 Services.”
Displaying ISDN events
The Show ISDN command enables the MAX unit to display the last 20 events that have
occurred on the specified ISDN line. Enter the command in the following format:
show isdn
line-number
where
line-number
is the number of the ISDN line. (For details about how lines are
numbered, see the Network Configuration Guide for your unit.) For example, to display
information about the leftmost built-in WAN port, you would enter the following command:
ascend% show isdn 0
The MAX unit responds with one or more of the following messages:
PH: ACTIVATED
PH: DEACTIVATED
NL: CALL REQUEST
NL: CLEAR REQUEST
NL: ANSWER REQUEST
NL: CALL CONNECTED
NL: CALL FAILED/T303 EXPIRY
NL: CALL CLEARED/L1 CHANGE
NL: CALL REJECTED/OTHER DEST
NL: CALL REJECTED/BAD CALL REF
NL: CALL REJECTED/NO VOICE CALLS
NL: CALL REJECTED/INVALID CONTENTS
NL: CALL REJECTED/BAD CHANNEL ID
NL: CALL FAILED/BAD PROGRESS IE
NL: CALL CLEARED WITH CAUSE
In some cases, the message can include a phone number (prefixed by #), a data service
(suffixed by K for Kbps), a channel number, TEI assignment, and cause code. For example, the
following information might appear:
PH: ACTIVATED
NL: CALL REQUEST: 64K, #442
NL: CALL CONNECTED: B2, #442
NL: CLEAR REQUEST: B1
NL: CALL CLEARED WITH CAUSE 16 B1 #442
