## Programming the System

Start RASC and check if all the boards have been detected. Then load the appropriate session for your country containing the trunk’s transmission levels and filter coefficients etc. (See RASC sessions for setting of tone and transmission parameters).

After programming background music or music-on-hold be sure to invoke a warm start to enable this function.

### Trunk programming

Trunk boards need special programming of the settings as required by the PTT network before the exchange can be used. In the RASC tool sessions are available for the specific markets, setting certain transmission parameters and tone characteristics e.g. level, cadences. Programming is executed with RASC. The following groups of commands have to be provided with proper values:

- External line parameters (group 10)
- Answer position for trunk lines (group 11)
- Line signalling diagrams (group 12)
- Register signalling diagrams (group 13)

The default values for trunk lines are 700 and following. Route 0 is to access to trunk 700. "9" is reserved for operator queue.

Refer to Fault Tracing Instructions (1545-ASB 150 02 Uen) showing the BTU-D start-up sequence.

### Tie line programming

#### BTU-C/2

Verify that the correct line signalling has been selected. Refer to command 1201 and select 12 for DC-loop signalling.

If DID with DTMF or MFC is used check if a board with register function is installed.

#### BTU-E

Verify that the far end has the same voice connection selected (2- or 4-wire).

Verify that the correct line signalling has been selected. Refer to command 1201 and select:

8 |  | Sweden E&M signalling

9 |  | Continuous E&M sign., A-Format

10 |  | Continuous E&M sign., D-Format

11 |  | Discontinuous E&M signalling

44 |  | CEPTL 1 (on BTU-E2)

45 |  | CAILHO discontinuous

46 |  | SSAC 15 - A (on BTU-E2)

If DTMF or MFC indialling is used, verify that a BTU-D or REG board is installed in the system. The same applies for the VMU-HD if the register function is activated.

### Programming the VMU HD (hard disk)

The hard disk should be inserted following prerequisites stated under Preparations for VMU-HD (hard disk). After the update invoke the following commands:

4603 |  | Enable data loading set to YES.

4450 |  | Load data after coldstart or board update. Not used if data is just added.

#### Announcement groups

The available announcement groups are 4401 to 4426 with groups 4411 to 4426 being only available on the VMU-HD.

4424 |  | The VMU-HD has all 64 references while the VMU-D provides only 32.

When invoking cold start or update card all data and messages are deleted but not the announcements.

### Number series

The completed exchange data sheets express the customer’s requirements with respect to facilities and number series. Program the system to the customer’s requirements. On initialisation the first ELU-_ board will acquire the extension numbers from 200 onward.

Note

If the system does not start up successfully and the red LEDs on nearly all cards are ON then the PROMs on the CPU-D(_) could be misplaced and must be corrected.
