9-103ANN-BD (Announcement Circuit Pack)
9
NOTE:
As memory locations are marked faulty, the amount of availab le
memory decreases, lowering the amount of announcement time
available on the circuit p ack.
k. A transient error that does not cause an alar m can occasionally oc cur
duri ng a SPE, TDM BUS, or Tone Cl ock interc han ge. Er ror Type 2049It
is possible for a marginal Tone-Clock circuit pack to cause this error
against the ANN-BD without alarming the TONE-BD. If this error occ urs
again, replacing the Tone-Clock circuit pack may cl ear up this error. See
the FAIL case in the Clock Match Inquiry Test (#212).
l. Error Type 3840This error is not service-affecting and no action is
required.
m. Error Type 217 and 267Indicate that there is more than one TN750
Announcement circuit p ack inserted in the system. Remove the alarme d
circuit pack.
n. Error Type 2Check the Class of Restriction (COR) administered for the
Data Line extension assigned to the TN750 for up loading and
downloading announc ements. The extension can be found b y using list
data-module.
o. Error Type 3999Indicates that the circuit pac k sent a large number of
control channel messages to the s witch within a short period of time. If
error type 1538 is also present, then the c ircuit pack was taken
out-of-service due to hype ractivity. 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 b e considered hyp eractive. This may
be completely normal d uring heavy traffic period s. However, if this error
type is logged when the circuit pac k is being lightly used , it may indicate a
problem with the circui t pack or the equip ment attached to it.

Always investigate tests in the order p resented in the table below whe n
inspecting errors in the sys tem. By clearing error cod es associated with the
Control Channel Looparound Test , for example, you may also clear errors
generated from other tests in the testing sequence.
