5.0 ATAS TESTING

5.1 Circuits tested by ATAS

ATAS will grab a new report from the WFA/C trouble list when the following conditions are met:

•

The circuit ID Service Code must be among the service codes in the ATAS tables.

•

The FLC code for the trouble report must be one that ATAS works from.

•

The trouble report must be a Customer Report (CR).

•

TEST field on the OSSTRE screen is populated with a “Y” (Yes).

•

The “TYPE” field on the OSSTRE screen must not be RFR.

The TEST field on the OSSTRE screen in WFA/C when populated with an “N” (NO) will trigger ATAS to add a note to

the log (OSSLOG) that the test flag is set to “N” and drop the ticket for manual intervention.

ATAS TEST FLOW

Below is a condensed recap of the ATAS trouble flow. See ATAS documentation for complete flows.

•

ATAS monitors the circuit in each direction for 15 seconds from the test point closest to the A end of the circuit.

ATAS notes access ID information in the log(OSSLOG).

•

ATAS looks for loopable devices on the WORD document. All ATAS tests are from the test point closest to the A

end, and will attempt to loop equipment farthest from the A end. Human Equipment Code Item(HECI) codes on a

WORD document identify loopable equipment. Verbiage such as “Demarc - 4W” on the WORD document also is

a trigger for ATAS to know there is loopable equipment. ATAS will assume there is a Smart Jack on the circuit

when “Demarc - 4W” verbiage is seen on the WORD document. This causes ATAS to attempt to loop the CSU at

the Z end of the circuit. ATAS will attempt to loop the circuit from the same test point it used to monitor the circuit.

•

Successful loopback of the CSU will result in a TOK - No trouble found message in the OSSLOG. CSU loopback

failure causes ATAS to attempt to loop the smart jack. ATAS continues with this sectionalization process.

•

ATAS will use the line code from the WORD document, however will check the other line code if errors are run on

a loopback. ATAS will note the line code used to produce error free results if other than the line code specified on

the WORD document.

DURATION OF ATAS TESTS

Loopback tests will be one minute in duration for all test patterns except all zeros. The all zeros test pattern is 15

seconds in duration.
