VoIP SERVICES ALARM MESSAGES
The NMC (Network Management Center) application Alcatel 4740 enables the following alarm mes-
sages specific to Voice over IP to be retrieved:
- Reset of VoIP CoCPU board xxxxx (message identical to those of the other boards in the system).
- VoIP CoCPU board xxxxx out of service.
• Diagnosis: reset and/or replace the board.
- DSP of VoIP CoCPU board xxxxx out of service.
• Diagnosis: reset and replace the VoIP CoCPU board if the fault persists or recurs.
- Ethernet interface of VoIP CoCPU board xxxxx Out of Service.
• Diagnosis: check the connection to the LAN and possibly the LAN components (Hub, switch,
etc.).
- Ethernet interface of VoIP CoCPU board xxxxx In Service.
- Remote gateway xxxxx Out of Service.
• Diagnosis: check the IP connectivity with the remote gateway (LAN, intermediate IP router) and
the status of the remote gateway.
- Remote gateway xxxxx In Service.
- External gatekeeper inaccessible.
• Diagnosis: check the IP connection with the external gatekeeper (LAN, intermediate IP router)
and the presence of the external gatekeeper.
- External gatekeeper refused.
• Diagnosis: check that the external gatekeeper has been configured correctly to accept the re-
gistration of Alcatel OmniPCX Office
- Automatic overflow: too much traffic to/from remote gateway xxxxx.
• Diagnosis: if this alarm occurs frequently, the bandwidth associated with this remote gateway
in the ARS table and the number of DSPs assigned to VoIP accesses must be increased if pos-
sible.
- Automatic overflow: VoIP call to/from gateway xxxxx refused because "not enough VoIP access
channels available".
• Diagnosis: if this alarm occurs frequently, the dimensioning of the DSPs must be reviewed:
either the bandwidth in the ARS table must be increased, or the number of DSPs assigned to
VoIP accesses must be increased, or another VoIP CoCPU board must be added.
- IP Telephony failures: no more DSP channels available.
• Diagnosis: if this alarm occurs frequently, the number of DSPs assigned to the IP subscriber pool
must be increased (either by reducing the number of VoIP access DSPs or by adding a VoIP Co-
CPU board).
- The IP Enabler cannot be initialized because of a DHCP server fault (no IP addresses available).
• Diagnosis: increase the number of IP addresses in the DHCP server range (this range of IP ad-
dresses must be greater than or equal to the number of IP Enablers to be installed).
