## Test Procedures

The following test-procedures ensure the proper functionality of the exchange.

### Extension lines

This test verifies that the extension lines and the telephones are connected and working.

##### The boards involved are

- ELU-A(2)
- ELU-C
- ELU-D3

#### Digital Telephones with/without display

Digital telephones can be connected to either ELU-D3 or ELU-C boards.

##### Start of test

1. Activity: Go to a telephone with display.
2. Activity: Read the display.

- Check: Does the telephone show the correct extension number?

1. Activity: Lift the handset.

- Check: Do you hear the dial tone?

1. Activity: Call an extension nearby and wait for it to ring. Pick up the other telephone and check for speech connection. Then hang up both phones.

- Check: Have all extensions been tested? If the answer is yes go to position 6.

1. Activity: Go to next telephone and continue with position 2.
2. End of test.

#### Analogue Telephones

Analogue telephones are connected to an ELU-A board.

To test, proceed similar to the digital telephones.

### Trunk lines

The test is designed to verify the connection between ASB 150 02 and the public exchange.

##### The following functions are to be verified

- digit transmission
- detection of external dial tone
- voice transmission
- detection of incoming call signal
- call metering

##### The boards involved are

- BTU-A
- BTU-A2
- BTU-B2
- BTU-C
- BTU-D
- BTU-E
- MFU

#### Preparations

- Use BMS to read out the individual number of the trunks connected to the system
- Connect a system telephone with display (A), to any line in the MDF.
  The telephone is permitted to initiate calls via all trunk lines
- Connect a system telephone with display (B), to any line in the MDF. This telephone shall be programmed as answer/reroute position for incoming calls via all BTU boards.

For the tests, it is desirable that the trunk lines have individual call numbers in the public exchange.

If this is not the case, a line can be selected by seizing all lines with the exception of the two used for each test.

##### Start of test

1. Activity: A goes off hook.

- Check: A receives dial tone.

1. Activity: A dials individual number of relevant trunk line.

- Check: A receives dial tone from public exchange.

1. Activity: A dials individual number of relevant trunk line in public exchange.

- Check: B receives external ring signal.

1. Activity: B answers.

- Check: A-B speech connection established.

1. Activity: A and B goes on hook.

- Check: None.

1. Activity: None.

- Check: Have all trunk lines been utilized for both incoming and outgoing calls? If yes, go to position 8, otherwise go to position 7.

1. Activity: Select next trunk line. Then go to position 1.

- Check: None.

1. Open all trunk lines that were seized.
2. End of test.

### VMU-boards

This test verifies the proper function of the VMU-(H)D board(s).

##### Start of test

1. Activity: Press the button named INFO on a telephone with display.

- Check: None.

1. Activity: Choose the function “absc”.

- Check: None

1. Activity: Choose the function “leave”.

- Check: None.

1. Activity: Choose the function “voice”.

- Check: None.

1. Activity: Speak.

- Check: None.

1. Activity: Choose the function “play”.

- Check: Verify that what you have said at position d is repeated by the telephone.

1. Activity: Have all VMU-board(s) been tested? If yes go to position 7.
2. End of test.

Note

When VMU-(H)D board(s) is (are) activated, the green LED will be lit.

### Cordless

Verify that the wiring to the Base Stations is correct.

#### Visual Checks

The power LED on every Base Station should be ON. The LEDs on the IC-CU2 and IC-LU boards should be OFF.

Note

Every Base Station accessible by persons other than trained personnel must have the cover mounted.

#### Test of the cordless

With the aid of the Cordless System Manager verify that the correct programming has been performed and using the systems menu check the status of the boards and Base Stations. The following test verifies the proper function of the integrated cordless system.

##### Start of test

1. Activity: Use a portable and dial an extension with display near by.

- Check: None.

1. Activity: Check that the correct calling extension number is displayed and pick up the ringing phone.

- Check: If voice connection has been established.

1. Activity: Put both telephone sets on hook.

- Check: None.

1. End of test

#### Radio Coverage Checks

The radio coverage verification consists of two tests:

- Base Station test,
- Area coverage test.

##### Start of Base Station test

The purpose of this test is to check if all Base Stations are operational.

1. Put a portable in the Service Display mode (refer to the Fault Tracing (1545-ASB 150 02 Uen).
2. Take ground plan (map) of the building where the Base Stations are indicated with their corresponding Base Station number.
3. Move close to each Base Station and check that the portable locks to it (the Service Display should display the correct Base Station number).

After having checked that all Base Stations are operational proceed with the area coverage test.

##### Start of Area Coverage test

The purpose of this test is to verify that there is satisfactory field strength to enable good speech quality everywhere within the covered area (rooms, elevator shafts, staircases). This test is executed with two portables and requires two persons.

1. Place the portable in the Service Display mode and call the other portable. One user of the portable should now start moving around the covered area. Both users must check that a good speech quality is maintained everywhere. Special attention should be paid to areas such as edges of the building and areas behind metal structures where there is a possibility of reduced speech quality.
2. Mark areas where RQI is not stable on 20hex and where cracking sounds or mutes are heard. A further Base Station should be installed in this area.

#### Portable Checks

This test checks for each portable the complete connection from system board to PABX. Furthermore it checks that the portables' numbers have been correctly programmed. The test is performed by calling all portables from one and the same portable.

1. Put all portables together in order of extension number on a table.
2. Go off-hook with each portable and check that the dial tone is heard.
3. Call with a portable (portable A) all other portables sequential and check that the portable with the corresponding number on its display rings when called.
4. Call portable A and check if it rings.

### IPU

#### Start test

##### Activity

Call a CN number which is only reachable via the VoIP line.

##### Check

If a connection can be established, the IPU is set-up correctly.

##### If a connection can’t be established, please perform the following steps

- Check whether the physical connection to the LAN is established (lower green LED in connection field 4 must be on).
- Check whether the DSM modules are mounted correctly (when selecting a VoIP-route the lower green LED in connection field 2 must be on). Use Command [dspinfo] of the IPU command line interface.
- Read out command 2152, to verify whether an IP-address is assigned to the IPU.
- To check the H.323 - or the proprietary gateway functionality of the IPU, program a so called loop via the LAN.

- Define a dummy PNR number and assign a new IP reference, referring to the IP-address of the own IPU.
- To enable incoming calls to the same IP-address for test purposes, the IP-address of the localhost (127.0.0.1) has to be defined in the IP-reference table, although there is no reference from the PNR table - needed for the proprietary protocol (101) only.

- Check with standard H.323 protocol - with gatekeeper assistance

- Define a dummy PNR number e.g. 7833 and assign IP reference = 0 (Call with Gatekeeper Assistance), do not remove any digits of the PNR, NPI for called numbers (command 9111) should be private/unknown
- "1000 node table": can be empty
- GW: set the Primary gatekeeper of the gateway with command 2191 (own IP address), NPI for called numbers incoming (command 2189) should be private/unknown. - Supported number = dummy PNR e.g. 7833
- GK: Activate the gatekeeper, trust your own gateway, check that the trusted GW state becomes "registered"
- Number Modification: remove the digits of the dummy PNR (number type private/unknown) - command 1930 =4

- Restart the IPU board!
- Program a supervision key for each IP trunk
- Dial the PNR number + an internal directory number in order to build up a so called loop via the LAN. If the call can be build up successfully, remove the previous configuration steps again and go to the next step, otherwise check all IPU commands again.
- Additional checks with a PC, which has to be located in the same LAN segment (subnet):
  open the DOS prompt and enter the command
  “ping <IP-address of the opposite node>”. If the address is not found, the address can’t be reached due to certain LAN configurations or the IP-address is not longer valid.

In case of speech delay variation or conversation interruption (due to packet loss) please check with the LAN administrator whether the routers are configured to support "Type of Service" (prioritization of voice packets) in the IP header.
