Introduction

...

• 1 PBX with a user (you can create a new user especially for the test or use the an existing one)
• 1 provisioned phone associated to this user
• 1 Dialplan procedure
• 1 provisioned BRI device (which was previously reset and upgraded to the latest version of firmware)
• 1 network cable to connect the ports involved in the test

...

The PBX plays the audio file in loop to keep the call running and give the possibility to test the device.   
It is recommended to perform this operation in the a specifically designed test environment in order to exclude the problems caused by some external factors, that could influence the result (the problems related to the operator, lines, configuration etc). 

The following logical scheme demonstrates the procedure. In this case W02BRI is used (in case W01BRI is tested, you need another BRI device, to set up the second port):

To perform the test:

• Create a user or use the an existing one to perform the test. In this example the user “test2” with the extension number 103 is used:
  

• Connect the Gateway to the Wildix test PBX and make the provisioning (refer to the online Guide if needed); connect the needed ports using the network cable RJ45:

...

“Up” indicates that the service works correctly, while “Down” indicates the problem on the line and/ or in the Gateway configuration:

Resolving issues with ISDN operator’s line connection

Issue 1.1. The physical link is not active

How to solve:

• Check/ substitute the wiring
• Check that the following wiring scheme is used (“straight” wiring):

...

• In case of the wiring to the network terminal Selta with DB9 connector, the correct scheme of the wiring is the following one:

Issue 1.2. The signal is not active

How to solve:

• Make sure that “Clock” is set up to “Use provided clock” in WMS -> Trunks, under the configuration menu of BRI/ PRI trunk
• Request an operator to check the line’s state

Resolving issues with PBX legacy/other devices connection

Issue 2.1. The physical link is not active 

How to solve:

• Check/ substitute the wiring
• Check the mode in which the ISDN interface of the PBX Legacy operates:
  • If it operates in TE mode with "Use provided clock" , the Wildix PRI Gateway should operate as NT with the clock set up to "Generate clock"
  • If it operates in NT mode with "Generate clock", the Wildix PRI Gateway should operate as TE with the clock set up to "Use provided clock"
