April 2000
Maintenance Objects
3-151ATM-EI (Expansion Interface Circuit Pack)
3
The problem is most likely
not
on the ATM-EI circuit pack reporting the
errors, but it could b e due to one or more of the following reasons:
The fiber is not snugly connec ted to either the board or the ATM
switch.
The PN packet bus is corrupting the cells. See Packet maintenance
objects (Aux Data 35 only).
The fiber between the ATM switch and the ATM-EI is too long
(greater than 2km for multimode fib er). Use loopback to see if the
fiber is corrupting the cells.
Some other ATM-EI board is not receiving the cells prop erly.
The intervening ATM switch is dropping the ATM cells due to a
shortage of bandwid th, or the DEFINITY is using more than the
subscribed bandwidth.
Error Type 771: the ATM switch is sending cells with unknown VPI and VCI
address (wrong connec tion).
1. Ensure that the ATM-EI board address on the ATM switch matches
the ATM-EI (ATM) address on the DEFINITY side.
i. Error Type 1024-1151: These errors represent problems detected by the
ATM-EI board in response to SETUP and ADDPARTY requests from
software.
The Error Types and descriptions are in Table 3-63:
Aux Data values represent port network and angel numbers and
are in Table 3-64.
