It indicates that the circuit pack has received a bad control message from
the switch.

o. Error Type 3857, 3858
uplink message is received from the 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
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.
p. Error Type 3872
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
q. Error type 3999
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 necessary to be considered hyperactive. This may
be completely normal during heavy traffic periods. However, if this error
type is logged when the circuit pack is being lightly used, it may indicate a
problem with the circuit pack or the equipment attached to it.
1. Whenever, the active archangel detects a loss of clock, it will alternate the state of the
CLKSEL lead until the lost clock signals are restored.
