Increment ID:   I22A1730
Date created:   NOV 22, 2000


Effect on Traffic:
------------------
This increment has no effect on traffic.


Title:
------
LAIC firmware robustness fix


Detailed Description of Increment:
----------------------------------
This increment provides a more robust LAIC firmware when it is running on
LAIC cards showing intermittent faulty behavior.  With it, internal buffer
management will be less affected by those card, as more validation is made
before performing actions on buffers. This way, less data corruption takes
place and more messages can be processed by the LAIC, before reaching the
circuit pack failure threshold.  However, the firmware fix does not alter
normal operation with good LAIC cards.


System Configuration / Shelf Type Requirements:
-----------------------------------------------
This increment must be applied to all AN17.30 AccessNode configurations
and shelf types.


Prerequisite Increments Required:
---------------------------------
Increments I01A1730 through I21A1730 must be successfully applied prior to
application of this increment.


Loads Affected:
---------------
SP: ANXSPL17BU
LAIC application load: LAICL17BU
LAIC BOOT load: LAICBL17BU


Installation Instructions:
--------------------------
Download increment from the Web:
Either a) download the increment directly to the /iswd directory on the OPC.
       b) download the increment to tape and insert into the OPC tape drive.

  3) Verify the increment delivered has the correct Title 
     and Description.  Also verify that the status is 
     "READY TO APPLY".

  4) Press any key to return to the main menu. 

Apply the increment:
  1) >From the ISD main menu, select Apply an Increment. 

  2) In the list, select the number next to the increment you delivered. 

  3) Select one of these options: 
     1) Apply to ALL NEs (to set the increment fully into the system) 
     2) Trial on one NE (to test the increment to ensure that it causes 
        no problems) 

     If you select option 2, a list of NEs in the span of control appears. 
     From the list of NEs, select the number next to the one you want to 
     test.  A confirmation screen appears. 

  4) Type y to verify your selection. 

  5) When the application is complete, press any key to scroll through 
     the Summary screen(s) until you return to the main menu.

  7) Select Display to Screen.

  8) Verify that the status next to each NE now reads "APPLIED" 
     (or "TRIAL APPLIED" if you chose to run a test in step 3 above). 

IF THE INCREMENT INVOLVES THE APU YOU MUST DO THE FOLLOWING STEP
Dump the image: 
  1) From the ISD main menu, select Dump an APU Image. 

  2) Select one of the valid load types that can be dumped.

  3) Select one of the valid NEs matching your previous parameters. 

  4) Type y to verify your selection. 

  5) When the image is complete, press any key to return to the main menu. 

  6) Repeat steps 2-5 for each load type available.
