Testing PCM Service

Testing PCM Service

After configuring a PCM service, you need to test whether the service is available.

Testing Z Interface Extension Services

After configuring a Z interface extension service, you need to test whether the service is available.

Prerequisites

Tools, Equipment, and Materials

U2000, one private branch exchange (PBX), two telephones, and three telephone lines

Test Connection Diagram
Figure 1-18  Connection diagram for testing a Z interface extension service

Procedure

  1. Connect Phone2 and NE1, the PBX and NE2, and the PBX and Phone1 using telephone lines, as shown in Figure 1-18.
  2. Query the number of the PBX port connected to NE2 and the number of the PBX port connected to Phone1 by following instructions in the PBX Product Description.

    NOTE:

    The number of the PBX port connected to Phone1 is the telephone number of Phone1, and the number of the PBX port connected to NE2 is the telephone number of Phone2.

  3. Test the availability of the Z interface extension service between Phone1 and Phone2.
    1. Pick up Phone1 and initiate a call to Phone 2. After Phone1 is picked up, a dial tone is heard. After the call is initiated, a ringback tone is heard.
    2. After Phone2 rings, pick up Phone2 and speak. Check voice quality. The voice should be clear and noiseless.

      NOTE:

      If voice quality is poor, improve voice quality by setting port gains on the two NEs using the NMS. To set port gains, select a board to be configured in NE Explorer and choose Configuration > Port Management from Function Tree. On the FXS Port Configurations or FXO Port Configurations tab page, set RX Gain(dB) and TX Gain(dB). In this example, set port gain for NE2 on the FXO PortConfigurations tab page and set port gain for NE1 on the FXS Port Configurations tab page. If the call volume is too low, increase the port gains. If the call volume is too high, decrease the port gains.

    3. Initiate a call at Phone2 and check voice quality using the same method.

Follow-up Procedure

  • If the test fails, check service configurations according to Configuring Z Interface Extension Services.
  • In this example, you can diagnose faults on the FXS port of NE1 by performing a loop line test or circuit line test on the NMS. To perform a loop line test or circuit line test, select a board to be tested in NE Explorer and choose Configuration > Port Management from Function Tree. On the FXS Port Configurations tab page, right-click the port to be tested and choose Circuit Test or Loop Line Test from the shortcut menu.

  2. Test the availability of the FXS hotline service between Phone1 and Phone2.
    1. Pick up Phone1 and initiate a call to Phone 2. A ringback tone is heard at Phone1.
    2. After Phone2 rings, pick up Phone2 and speak. Check voice quality. The voice should be clear and noiseless.

      NOTE:

      If voice quality is poor, improve voice quality by setting port gains on the two NEs using the NMS. To set port gains, select the board to be configured in NE Explorer. Choose Configuration > Port Management from Function Tree. On the FXS Port Configurations tab page, set RX Gain(dB) and TX Gain(dB). If the call volume is too low, increase the port gains. If the call volume is too high, decrease the port gains.

    3. Initiate a call at Phone2 and check voice quality using the same method.

Follow-up Procedure

  • If the test fails, check service configurations by referring to Configuring Hotline Services.
  • In this example, you can diagnose faults on the FXS ports of NE1 and NE2 through a loop line test or circuit line test on the NMS. To perform a loop line test or circuit line test, select the board to be tested in NE Explorer. Choose Configuration > Port Management from Function Tree. On the FXS Port Configurations tab page, right-click the port to be tested and choose Circuit Test or Loop Line Test from the shortcut menu.

After configuring 2/4-wire audio and E&M trunk services, you need to test whether the services are available.

Prerequisites

Tools, Equipment, and Materials

U2000, two private branch exchanges (PBXs), two telephones, and four telephone lines

Test Connection Diagram
Figure 1-20  Connection diagram for testing 2/4-wire audio and E&M trunk services
NOTE:

    1. Pick up Phone1 and initiate a call to Phone 2. After Phone1 is picked up, a dial tone is heard. After the call is initiated, a ringback tone is heard.
    2. After Phone2 rings, pick up Phone2 and speak. Check voice quality. The voice should be clear and noiseless.

      NOTE:

      If voice quality is poor, improve voice quality by setting port gains on the two NEs using the NMS. To set port gains, select the board to be configured in NE Explorer. Choose Configuration > Port Management from Function Tree. On the ATI Port Configurations tab page, set RX Gain(dB) and TX Gain(dB). If the call volume is too low, increase the port gains. If the call volume is too high, decrease the port gains.

    3. Initiate a call at Phone2 and check voice quality using the same method.

    NOTE:

    If the test fails, check service configurations by referring to Configuring 2- or 4-Wire Audio and E&M Trunk Services.

    NOTE:

    Considering the AC voltage as an example, the following describes how to check Test Result by setting Test Judgment Criteria. The similar goes to other parameters.

    • In Test Judgment Criteria, AC Voltage Threshold (V) takes the default value 55, indicating that if the AC voltage exceeds the threshold value 55 V, wire A or wire B of the AC power cable touches an electrical power cable.
    • In Test Result, A-> ground AC voltage (V) is 0.000, indicating that the AC voltage is lower than the threshold value and that wire A of the AC power cable does not touch an electrical power cable.
    • In Test Result, B-> ground AC voltage (V) is 0.000, indicating that the AC voltage is lower than the threshold value and that wire B of the AC power cable does not touch an electrical power cable.
    • In Test Result, A->B AC voltage (V) is 0.000, indicating that the AC voltage is lower than the threshold value and that wire A and wire B of the AC power cable do not touch an electrical power cable.
