h. Excessive I-frame retransmission. Could indicate a noisy link. Recover as
in previous note. Aux values indicate the retransmission rate per minute.
See the "Link Recovery" section.
i. If the Aux Data value is 9, then the destination circuit pack (DIG-BD or
DS1-BD) is not inserted. Otherwise, DS1 maintenance detected a
hardware failure. (DS1 cable disconnected, loss of signal, DS1-BD
problems.) Not a Processor Interface Link problem. Check DS1-BD
maintenance. Only applicable to ISDN links. Aux value useless. Once the
DS1 signal is restored, maintenance automatically restarts the Processor
Interface Link. To hasten this process, test the appropriate DS1 Interface
circuit pack via test board PCS command. When Test #138 (loss of
signal) passes, the Processor Interface Link recovers shortly.
In addition to an indication that the link failed to establish the PI-LINK 2561
AUX_Data, the hardware error log is also updated. This error may indicate
two possible conditions:
1. A failure to detect the DTR from the peripheral.
When the DTR is not detected by the data module the AUX_Data is
set to 40. This indicates that the problem is most likely with the
peripheral or the connection to the peripheral.
2. A time-out on the EIA interface query request to the data module.
When the data module fails to respond to the EIA interface (query
request) the AUX_Data is set to 41. This may indicate problems
with the data module or connection to the data module. Other
errors specific to the data module may also be logged if this is the
case.
j. TN765 PI-BD determined that the ISDN link went down. Check
connectivity with the other end. Busyout and then release the link to
recover. Occurs if DS1 maintenance detected a problem or the remote
end is busied out or is down. This also occurs if the ISDN link is unstable
or if there is excessive noise on the line. See the "Link Recovery" section.
k. Excessive LAPD (link-access procedure on the D-channel) invalid frame
errors. Could be a noisy line or problems with the TN765 Processor
Interface circuit pack. Also check DS1-BD Maintenance documentation.
See the "Link Recovery" section.
l. Occurs 90 seconds after a 2817 Error Code if link does not recover. At this
time, all ISDN trunks associated with this link are put into a maintenance
far-end state (see ISDN-TRK for details). See the "Link Recovery" section.
m. The application level process associated with the link has failed to
establish a data connection with the far end. This problem prevents data
from being processed. The condition may exist even if the link is in a data
transfer state. Busyout, and release the link to restart it. This is not a
Processor Interface hardware problem.
