AMX instruction manual Testing the AXB-DTMF+, Off-hook line and off-hook phone troubleshooting

Configuration and Installation

Testing the AXB-DTMF+

Follow these steps to test the AXB-DTMF+:

1.Disconnect AXlink power.

2.Remove the cover from the unit housing and set the AUTO ANSWER jumper to AUTO ANSWER ON then reinstall the cover on the unit housing.

3.Reconnect AXlink power. The status LEDs should blink in sequence from right to left and the AXlink green LED should be blinking.

4.Place a call to the AXB-DTMF+ from an outside line.

5.The RING LED should light with an incoming ring.

6.The OFF HOOK LINE LED should light after 1 ring.

7.The DTMF RX LED should light when tones are sent from the calling telephone.

8.Check line quality and operation using an extension telephone connected to the PHONE jack.

9.Return the AUTO ANSWER jumper to OFF position, if desired.

Off-hook line and off-hook phone troubleshooting

The off-hook line and off-hook phone LEDs light only if there is a good telephone line connection. If either the off-hook line or off-hook phone LED fails to light, a faulty telephone line connection is indicated.

Make sure a proper phone line connection exists to light both off-hook and extension off-hook LEDs. Test the off-hook line by following these test procedures:

The extension telephone is optional and supplied by the user.

1.Take the AXB-DTMF+ off-hook by issuing the off-hook Send_Command from the central controller. If there is a good telephone line connection, then the OFF HOOK LINE LED lights.

2.If the OFF HOOK LINE LED fails to light, then there is a bad or faulty telephone line connection. Check the incoming telephone line and make sure it is working properly. Then, check the RJ-11 cable and its connection to the AXB-DTMF+.

Test the off-hook phone using the following steps:

1.Take the receiver off the extension telephone. If there is a good telephone line connection, then the EXTENSION OFF HOOK LED lights.

2.If the OFF HOOK PHONE LED fails to activate, make sure that an extension off-hook

Send_Command has not been issued (you can do a Send_Command extension on-hook to be sure; see the Operative Send_Commands section on page 7 for details). If this does not produce results, then there is a faulty telephone line connection. Check the incoming telephone line and make sure it is working properly. Then, check the RJ-11 cable and its connection to the AXB-DTMF+. Make sure the RJ-11 cable from the extension telephone is good.
