Communication Manager Maintenance Object Repair Procedures
Note: Whenever,
p. Error Type 3848: the IPSI or Tone-Clock circuit pack had a loss of clock. If error 2305 is
also logged, see Note (k).
q. Error Type 3856: the IPSI or Tone-Clock circuit pack had a loss of clock. If error 2305 is
also logged, see Note (l) for Error Type 2305.
r. Error Type 3857 and 3858: these errors are reported by software when an uplink message
is received from the active IPSI’s Archangel firmware. Both Error Types indicate that a loss
of one or more clock signals were detected by the archangel, and subsequently restored by
changing the CLKSEL lead.
Note:
the active archangel detects a loss of clock, it will alternate the state
of the CLKSEL lead until the lost clock signals are restored.
If the IPSI archangel restores the clock signals by activating the [A] IPSI/
Tone-Clock, then Error Type 3857 is reported. If the clock signals are restored by
activating the [B] IPSI/Tone-Clock, then Error Type 3858 is reported. A Cold 2
Restart should occur in a port network immediately after Error Type 3857 or 3858
is reported.
Duplex Reliability — Since there is only one IPSI in the port network, Error Type 3858 can
never occur. When Error Type 3857 occurs, it means the [A] IPSI archangel experienced a
loss of clock, but clocking was subsequently restored using the [A] IPSI/Tone-Clock.
High or Critical Reliability — If the [B] IPSI is active and the [A] IPSI is healthy when Error
Type 3857 is reported, then software attempts to initiate an IPSI interchange to activate the
archangel and PKT-INT on the [A] IPSI, thereby ensuring that the active Tone-Clock,
PKT-INT, and archangel are all on the same IPSI. If the [A] IPSI is unhealthy, then software
initiates a transition to EI-Fallback mode. If the [A] IPSI is active when Error Type 3857 is
reported, it means the archangel for the [A] IPSI had to switch the state of the CLKSEL lead
more than once to restore the lost clock signals.
When Error Type 3858 is reported, if the [A] IPSI is active and the [B] IPSI is healthy, then
software attempts to initiate an IPSI interchange to activate the archangel and PKT-INT on
the [B] IPSI. If the [B] IPSI is unhealthy, then software initiates a transition to EI-Fallback
mode. If the [B] IPSI is active when Error Type 3858 is reported, it means the archangel for
the [B] IPSI had to switch the state of the CLKSEL lead more than once to restore the lost
clock signals.
For the high and critical reliability configurations, Error Type 2305 should be logged against
TONE-BD for the standby IPSI/Tone-Clock after Error Type 3857 or 3858 is reported.
s. Error Type 3872: an IPSI or Tone-Clock circuit pack had a loss of Data Clocks. This error
will impact mainly users on station connected to Digital circuit packs. These users could be
with out service. If error 2049 is also logged see Note (k).
t. Error Type 3999: the circuit pack sent a large number of control channel messages to the
switch within a short period of time. If Error Type 1538 is also present, then the circuit pack
was taken out of service due to hyperactivity. If Error Type 1538 is not present, then the
circuit pack has not been taken out of service, but it has generated 50% of the messages
