Configuration Flow

Configuration Flow

This section describes how to configure PCM services and multiplexer group services.

PCM Service Configuration Process

This section describes the process for configuring a pulse code modulation (PCM) service.

Table 2-9 provides the process for configuring a PCM service.

Figure 2-21  Process for configuring a PCM service

Table 2-9  Process for configuring a PCM service
Step Operation Remarks
1 Configuring the Sub-rate Encapsulation Mode

Optional.

To configure a PCM service on an DXM board, configure the sub-rate encapsulation mode (V.110 or X.50 D3) according to the service plan.

2 Configuring a PCM Port

Required.

Configure port attribute parameters for a PCM board. Set the required parameters based on actual network conditions.

Set parameters as follows:

  • Select the board and service port, for example, 1-DXM-1(DDN-1), according to the service plan.
  • Set Protocol Mode (for example, RS232 Mode).
  • Set Serial Port Rate, for example, 9.6K (X.50 D3).
  • Set Phase Mode and Synchronous.
NOTE:

To configure Z interface extension services, FXS private-line services, or 2- or 4-wire audio and E&M trunk services on DXM boards, set Working Mode of internal ports to PCM30.

To set Working Mode, select an DXM board from the NE Explorer and choose Configuration > Framed E1 Interface from the navigation tree. Then, click Internal Port.

3 Configuring a DDN Clock Source

Required.

PCM services require clock synchronization between the interconnected NEs. It is advised to configure the DDN clock source on a peer third-party NE to trace the local Huawei NE, and retain the default value Local 2M System Clock for Clock Source Trace of the local Huawei NE.
NOTE:
Asynchronous sub-rate services do not require clock synchronization.
4 Configuring PCM Services

Required.

Configure 8 kbit/s and 64 kbit/s services. Set the required service parameters for PCM service encapsulation and access according to the service plan.

Set parameters as follows:
  • Select Source E1 and Sink E1, for example, DDN-9 or 2M-1(SDH_TU-65).
  • Set Source Timeslot Range and Sink Timeslot Range.
  • Set Bandwidth.
5 Creating SDH Services

Required.

Configure a cross-connection between the port for receiving/transmitting the PCM service and an SDH link. Set the required parameters according to the service plan.

Set parameters as follows:

  • Select Source slot and Sink slot of the link according to the service plan.
  • Configure Source Timeslot Range and Sink Timeslot Range.

PCM service: Testing PCM Services

G.703 64 kbit/s codirectional service: Testing DDN Services

Required.

After the PCM service is created, verify the service continuity.

Configuration Flow for Multiplexer Group Services

This section describes the configuration flow for multiplexer group services.

Table 2-10 shows the flow for configuring multiplexer group services.

Figure 2-22  Flow for configuring multiplexer group services

Table 2-10  Process for configuring multiplexer group services
Step Operation Remarks
1 Configuring the Sub-rate Encapsulation Mode

Optional.

To configure a multiplexer-group service, configure the sub-rate encapsulation mode (V.110 or X.50 D3) according to the service plan.
NOTE:
For pure data multiplexer-group services, the sub-rate encapsulation mode must be configured.
2 Configuring a PCM Port

Required.

For a data multiplexer group, configure only serial port management parameters for DXM boards. For an audio multiplexer group, configure port management parameters for DXM boards. Set parameter values according to the actual network plan.

Set serial port management attributes:
  • Select the board and service port, for example, 1-DXM-1(DDN-1), according to the service plan.
  • Set Loopback Mode to Non-Loopback.
  • Set Serial Port Rate, for example, 9.6K (X.50 D3).
  • Set Phase Mode and Synchronous.
Set serial port management attributes:
  • Select Port, for example, 1-DXM-1(DDN-1), according to the service plan.
  • Set Port Type to FXS Port.
  • Set Service Type to Hotline service.
  • Set A-Law/μ-Law to A-Law for the common members in the VF multiplexer group.
Set parameters for framed E1 ports as follows:
  • Set Working Mode to a proper value according to the service plan, such as PCM30.
NOTE:
For an audio multiplexer group, set Working Mode for Internal Port and External Port to PCM30 if Signaling Mode is 1E1M or 2E2M. If Signaling Mode is None, you do not need to specify Working Mode.
3 Configuring a DDN Clock Source

Required.

PCM services require clock synchronization between the interconnected NEs. It is advised to configure the DDN clock source on a peer third-party NE to trace the local Huawei NE, and retain the default value Local 2M System Clock for Clock Source Trace of the local Huawei NE.
NOTE:
Asynchronous sub-rate services do not require clock synchronization.
4 Configuring Multiplexer Group Services

Required.

Configure a multiplexer group service. Set parameter values according to the actual network plan. Currently, DXM boards support four multiplexer group modes: data-P2MP, data-meeting, VF-P2MP, and VF-meeting. You can specify the desired mode according to the actual networking condition.

5 Creating SDH Services

Required.

Configure cross-connections between multiplexer group service access ports and SDH links. Set parameter values according to the actual service plan.

Set parameters as follows:

  • Select Source slot and Sink slot of the link according to the service plan.
  • Set Source Timeslot Range and Sink Timeslot Range.
6 Testing Multiplexer Group Services

Required.

Verify availability of configured multiplexer group services.

Dry Contact Service Configuration Process

This section introduces the dry contact service configuration process.

Table 2-11 shows the dry contact service configuration process.

Figure 2-23  Dry contact service configuration process

Table 2-11  Dry contact service configuration process
Process Operation Remarks
1 Configuring the E1 Transmission Mode

This step is mandatory.

When dry contact services are configured, the E1 transmission mode needs to be configured based on service planning. The board currently supports E1 mode and 64K mode. The E1 mode is configured by default.

2 Dry Contact Service Configuration

This step is mandatory.

When dry contact services are configured, the input and output relay parameters need to be configured. Specify the values based on the actual networking situation.

3 Configuring Dry Contact Signal Combination

This step is mandatory.

When dry contact services are configured, dry contact signal combination needs to be configured based on service planning.

4 Creating SDH Services
NOTE:
This link is the general configuration for creating SDH services. Note that the SDH/PDH cross-connections of dry contact services are unidirectional.

This step is optional.

When cross-connections of dry contact services from the system side to SDH links are configured, parameters are configured based on service planning to implement dry contact signal transmission.

5 Testing Dry Contact Services

This step is mandatory.

After dry contact services are created, the connectivity of the services needs to be verified.
