REMOTE DEVICE CONNECTIVITY
Problem:
A remote device is not able to connect to the CyberSWITCH.
Set-up:
The system software should be up and running. (At the administration console: if you are in the
Connection Monitor window, exit to the “[System Name] >” prompt.)
1. Enable the call trace messages with the
trace on
console command.
2. Erase the current system messages using the
er
console command.
3. In a controlled manner, initiate an ISDN connection from the remote device.
Action:
1. After a connection has been initiated, view the system messages (display system messages by
issuing the
dr
console command). Look for the following call request messages among the
system messages:
In - INCOMING CALL Call Id=<call Id> Slot =<slot #> Port=<port #> Chans=<bearer
channel map> Ces=<comm endpoint suffix> Rate=<data rate>
Out - CONNECT Call Id=<call Id> Slot=<slot #> Port=<port #> Chans=<bearer
channel map> Ces=<communication endpoint suffix> ConnId=<connect Id>
In - CONNECT Call Id=<call Id> Slot=<slot#> Port=<port #> Chans=<bearer channel
map> Ces=<communication endpoint suffix> ConnId=<connect Id>
If the system reports these messages, then continue with the next step.
If the system does not report these messages, the remote device is not correctly connecting to
the system. Check and verify the configuration of the remote device.
2. If the system displays the following message among the system messages (display system
messages by issuing the
dr
console command),
Security Rejection-Invalid Calling Line Id - <#>
the network is indicating a calling line identifier that is not configured for any valid device in
the system Device list. The number “#” indicates the actual number presented by the network.
3. For Remote Bridge Devices:
If the system displays the following messages among the system messages,
Security Rejection - Caller did not negotiate security
Security Rejection - No Bridge Address given by caller
Security Rejection - Unknown Calling Bridge
Security Rejection - No Password given by caller
Security Rejection - Invalid Password given
Security Rejection - HDLC not supported by the caller
review the system configuration for the Device List. You can also refer to the System Messages
chapter for the message meanings and the appropriate actions to be taken.
4. For IP Host Devices:
If the system displays the following messages among the system messages:
IP Call Dropped: ID_RSP was not received from remote
IP Call Dropped: XID was not received from remote
