1. If the same Error Type/Aux Data value occurs more than once in a
24 hour period, the circ uit pack should b e replaced. See ‘‘Shutting
down NT on the TN802’’ before removing the circuit pack.
If the MAPD board detects only o ne of these hardware problems, then the
error is resolved when none of these faults are detec ted for 10 minutes.
h. Error Type 51 4: LAN Extern al RAM Err or; ha rdwar e faul t in th e PPE
external RAM, used for message buffering to and from the Packet Bus.
This error should not occur regular ly.
1. If this error occurs 10 times within 30 minutes, rep lace the circuit
pack. See ‘‘Shutting down NT on the TN802’’ before removing the
circuit pack.
i. Error Type 769: Transmit FIFO Underflow (threshold is 3 errors within 10
minutes); the circuit pac k cannot find the “end of frame” bit when
transmitting a frame to Packet Bus.
1. Clear the alarm using the following c ommand sequence :
a. busyout board UUCSS
b. reset board UUCSS
c. test board UUCSS long clear
d. release board UUCSS
2. If the error recurs within 10 minutes, replace th e circuit pack. See
‘‘Shutting down NT on the TN802’’ before removing the circuit p ack.
j. Error Type 770: unable to Write LAN T ranslation RAM (threshold is 2 errors
within 10 minutes); a call is abor ted because there are no availab le
translation RAM locations for the call connec tion attempt.
1. Clear the alarm using the following c ommand sequence :
a. busyout board UUCSS
b. reset board UUCSS
c. test board UUCSS long clear
d. release board UUCSS
2. If the error recurs within 10 minutes, replace th e circuit pack. See
‘‘Shutting down NT on the TN802’’ before removing the circuit p ack.
k. Error Type 1537: LAN Bus Timeout; the circuit pack transmitted too m any
bytes on the LAN bus for a sing le frame. This condition may be caused by:
■an on-board fault
■faulty data received on one of the circuit pack’s exter nal ports. If
any of the ports on this circui t pack are alarmed, refer to the rep air
procedures for those maintenanc e objects.
