STEP 8 5 MONITOR 6 SIMULATE WINK 7 SIMULATE DELAY DIAL 8 SIMULATE BYLINK STEP 9 READ SET MS STEP 10 SET DBM TEST STEP 11 STEP 12 STEP 13 STEP 14 11 Select the correct function in accordance with trunk type. All equal access trunks use SIMULATE WINK, as do 911 and DID circuits. Select READ, If you wish to alter the default thresholds for digit power and duration. The default settings are 30 ms and -24 d. Bm. If READ was selected in STEP 9 use the SET MS and SET DBM keys to change the default settings. A change will occur and be displayed with each key depression. SET DBM will step from -24 to +4 in 2 db steps. SET MS will step from 30 ms to 120 ms in 5 ms steps. Select TEST BOTH Select BOTH NORM Select NORM. AUTO Select AUTO. After a record with an error occurs the 966 A will change to HOLD while the event is logged. After the event is logged, the Test Set will automatically switch to AUTO. SEE NOTES ON NEXT SLIDE 23

TEST #2 TESTING IN A TERMINATING MODE First go to Feature Select. You will see [AUTO] [SUPER] displayed. Press and release the MANUAL button. You will see PR 1 110. Press the EXAMINE button. You will see DUR 1 150. Press the EXAMINE button two more times. You will cycle past DUR 2 200 and then return to PR 1 110. You can adjust whichever value is showing in the display. PR means pre-wink or idle time. DUR means wink of off-hook duration time. All readings are in milliseconds. The limits are 20 MS to 500 MS. Pressing the AUTO button causes the count to go up. Pressing the HOLD button causes the count to go down. At first the count changes by 1, but if you hold the AUTO or HOLD button, after 10 counts, the count will change by 10 each time. If you release and press the button again, the count changes by 1. When you approach the limits, the count will change by 1 for approximately the last 10 digits, even if you were moving by tens. When you reach the end limit, the count will flash. To reset the wink timing to default timing press the HOLD and AUTO keys at the same time. If takes about 1 second for the defaults to be reset. You must be in wink adjust mode to reset to default timing. There is a 90 MS stand off built into the first pre-wink (PR 1). This means that if you adjust the PR 1 setting to its minimum of 20 MS, you will record a pre-wink time of 110 MS (90 + 20). Always add the stand off time to the display to figure total expected time from line seizure to wink. PR 1 and DUR 1 refer only to the starting wink. DUR 2 refers to all other winks except IDDD winks, which are set to 100 MS and are not adjustable. To exit the wink adjust mode, press the MANUAL button. This returns you to the [AUTO][SUPER] display. 24

TEST #3 TEST PROCEDURE FOR EQUAL ACCESS IDDD This procedure is performed at an analog signal point, with the 966 A-L 3 performing the terminating office functions. NOTE: If you wish to have a printer or PC attached to the 966 A, connect the printer or PC before turning on the power in STEP 1. If the printer was set for 1200 bps 7 data bits, even parity, one stop bit, Xon -Xoff disabled and attached to the 966 A prior to Step 1, a message stating copyright and 966 A switch settings would have been printed (assuming the ON-LINE mode of the printer was enabled). If no copyright message appears, turn the 966 Aoff and check all connections and printer settings. The only thing that the 966 A can change via the front panel is the baud rate which is done during the self-check cycle. Refer to your Operator’s Manual for complete details. STEP 1 Turn the set ON. After self-check is complete, these LEDs should be illuminated: REC 1, OFF, LOOP NORMAL, MONITOR, BOTH, NORM & AUTO. All other LEDs will be dark. POWER STEP 2 TR Connect TR to TR of circuit under test. T 1 R 1 E&M Connect T 1 R 1 to T 1 R 1 of circuit under test. Connect E&M to E&M of circuit under test. STEP 3 F OFF Depress the OFF/F key to enable the eleven possible feature selections. The F key LED is blinking. Use Features 1 through 5 for Non-Equal Access. Use Features 6 through 11 for Equal Access calls. 25

(6 = 1 record, 7 = 2 records, 8 = 3 records). The associated LEDs will blink after selections. Key 9, 10 or 11 must be selected to match the wink back after required for each record (9 = wink back after record 1, 10 = wink back after record 1, and 11 = wink back after record 3). For example: If 2 records are needed to complete the IDDD call and a wink is required after each record, press keys 7, 9 and 10. The 966 A will also send more than 1 wink between records. 26

TEST #3 TEST PROCEDURE FOR EQUAL ACCESS IDDD STEP 5 X EXAMINE ERROR The first depression of this key will result in the word [AUTO] appearing in the first set of brackets. A second depression will result in the word [SUPER] appearing in the second bracket. A third depression will result in both AUTO and SUPER flashing. If you are on the receive side of the DS 1 circuit select [AUTO]. If you are on the transmit side, select [AUTO] and [SUPER]. AUTO blinks on and off and prepares the set to automatically print any record with an error and then return to testing. Without this feature the 966 A will hold the record until the operator reviews the errors. SUPER blinks on and off and prepares the set to give interdigit and wink times. Wink timing details will only be printed if you are monitoring or simulating a wink start circuit. If no wink is sent or if a wink is mutilated, no time is recorded. If you are monitoring or simulating an equal access line, the last time given is called END-WINK to TERM OFF-HOOK. STEP 6 F OFF LOOP NORMA L STEP 7 LOOP REVERSE E&M ORIGNATING E&M TERMINATING STEP 8 6 STEP 9 11 SIMULATE WINK BOTH Depress the OFF/F key to lock in feature selection(s). Select Trunk Type in accordance with location and cable connections. The 966 A will now display all recorded digits. NOTE: If the Digital Interface is being used for access to a DS 0 circuit, E & M TERMINATING MUST be the selection. Select SIMULATE WINK. Select BOTH. 27
