5.7 Automatic redialing function requirement

5.7.1 Automatic dialing function requirement

5.7.1.1 Automatic repeated call attempts


Requirement:

  1. If an automatic repeated dial without dial tone detection, the dial digit should not send out within 2 seconds after on line.

  2. The Automatic repeated call should be equal or no more than 2 attempts and should wait more than or equal 1 minute after previor attemp.

  3. The Automatic repeated call is no limits on attempts if the wait time of repeated call is more than or equal 3 minutes after previor attemp.

  4. For Emergency call, the repeated call attempt is no limited.

Purpose: To prevent the unreasonable wast to the using of PSTN source.

Test method:



    1. Automatic repeated call attempts test circuit as Figure 48.

    2. Automatic repeated call attempts test method:

  1. Set loop simulator without sending dial tone and with sending busy tone after received all digits of the call.

  2. Set TE to automatic repeated call attemp mode.

  3. Measure and record the AC and DC voltage on the line of the test.

  4. Caculate the time from loop start to first digit sent out.

  5. Caculate the time from TE goes off line to the next on line.

  6. Count the total attempts of repeated calls, not including the first call.

5.7.1.2 Disconnection Time of automatic dialing


Requirement:

  1. Disconnection Time should be less than 20 seconds after busy tone send out.

  2. Disconnection Time should be less than 2 minutes of no answering ring back signals.

Purpose: To prevent the unreasonable design of TE to waisting of PSTN source.

Test method:



    1. Disconnection Time of automatic dialing test as Figure 48.

    2. Disconnection Time of automatic dialing test method:

  1. Loop simulator set to send busy tone after receiving the dial digits.

  2. TE set at automatic dial mode.

  3. Measuring the AC and DC voltage during all the test.

  4. Caculate the time when last digit dialled to release the line.

  5. Loop simulator set to send ring back tone after receiving the dial digits.

  6. Repaet step (2) to (4).

Test equipment:

  1. Loop Simulator.

  2. Storage Type Oscilloscope.



5.7.2 Automatic answer function requirement


Requirement: TE with Automatic answer function should

      1. Seizure the calling line before receiving more than 3 cycle rings.

      2. Release the line before passing more than 3 seconds after the calling party released the line at the other side.

Note: Item(2) is only suitable for the moden function TTE.

Purpose: To prevent the unreasonable design of TE in waisting of PSTN source.

Test method:


    1. Automatic answering function test as Figure 49.

    2. Automatic answering function test method:

  1. Set TE at on-hook mode.

  2. Using the calling party equipment diall to theTE.

  3. Loop simulator will send rings to TE.

  4. Count the number of rings received by TE till the line is seizured.

  5. Change calling side to turn to on-hook mode.

  6. Wait untill TE turn to on-hook mode.

  7. Record the timing and DC voltage in step (5) to (6).

  8. Caculate the time between calling party release the line and TE release the line.
