Communication Manager Maintenance Object Repair Procedures
2. Remove the ATM-INTF administration and re-administer the slot (change circuit-pack)
to match the circuit-pack that is physically present in this slot.
f. Error Type 131: An ATM-EI circuit pack has been removed from the slot for 5 minutes.
1. Insert the ATM-EI circuit pack into its administered slot.
2. Another way to resolve or prevent this alarm is to remove the ATM-EI administration.
See Basic ATM PNC Administration, then remove the ATM-INTF administration
(change circuit-pack).
It is possible that the ATM-EI could be held in reset by the PN’s Maintenance board and is
not inserted in the system.
3. Try test maint P long on the maintenance board in the same PN.
g. Error Type 257: Expansion Interface Control Chel Test (#316) failed (board cot
communicate on the TDM bus control chel). Follow the suggested test procedures.
Error Type 258: The archangel is out of sequence (Aux Data indicates Angel number).
Error type 259: The expansion archangel link (EAL) to the active ATM-EI board is down.
See SYS-LINK (System Links).
h. Error Type 513: The ATM Crosstalk test failed. The board is either writing to or reading
from a TDM time slot that is not allocated to the board.
1. Test the board (test board location), and follow the procedures suggested for
this test. In random tests of a single DSP during low or high traffic, the same DSP can
be tested more than once.
i. Error Types 769 and 770: are board-degraded alarm errors that result when the ATM
switch is sending corrupted cells or excessive AAL/LAPD retransmissions (off-board ATM
cell corruption errors). These errors indicate the detection of a problem in handling ATM
cells that are received from the fiber interface.
Aux Data for these Error Types:
Error Type Aux Data Description
769 34 Excessive AAL-5 retransmission requests
769 35 Excessive LAPD retransmission requests
770 25 Uncorrectable ATM cell headers – threshold
771 26 VPI, VCI pair unknown
The problem is most likely not on the ATM-EI circuit pack reporting the errors, but it could
be due to one or more of the following reasons:
● The fiber is not snugly connected to either the board or the ATM switch.
● The PN’s packet bus is corrupting the cells. See PKT-BUS (Packet Bus) (Aux Data 35
only).
