Configuring the VoIP ISDN PRA User

Configuring the VoIP ISDN PRA User

This topic describes how to configure the VoIP ISDN PRA user. After the MG interface is configured, you can add the VoIP ISDN PRA user on this interface to implement the VoIP ISDN PRA service.

Configuring the Attributes of the E1 Port

This topic describes how to configure the attributes of the E1 port to ensure that the ISDN PRA port meets the actual application requirements.

Context

You can configure the impedance, line coding mode, and working mode of the E1 port.

Default Configuration
Table 1-48 lists the default values of the E1 port. When configuring the attributes of the E1 port, you need to modify the values according to the service requirements.
Table 1-48 Default values of the E1 port

Parameter

Default Setting

Port impedance

E1 mode: 75 ohm

Line coding mode

E1 mode: HDB3

CRC4

Enable

The mode for digital section access

Digital

Signaling type

CCS

Procedure

  1. In global config mode, run the interface edt command to enter the EDT mode.
  2. (Optional) Run the e1port impedance command to configure the impedance of an E1 port.
  3. (Optional; perform this step when you need to modify the line coding mode of the port) Run the e1port line-code command to configure the line coding mode of the E1 port.

    NOTE:

    In E1 mode, the system supports two line coding modes, namely, HDB3 and AMI.

  4. (Optional) Run the e1port crc4 command to configure the CRC4 function of an E1 port.
  5. (Optional) Run the e1port attribute set command to configure the digital section access mode of an E1 port.
  6. (Optional) Run the e1port signal command to configure the signaling type of an E1 port.

Example

Assume that the E1 ports on ISDN PRA board work in HDB3 line encoding mode, the CRC4 function is enable, To configure such E1 ports, do as follows:

huawei(config)#interface edt 0/1
huawei(config-if-edt-0/1)#e1port line-code 1 HDB3
huawei(config-if-edt-0/1)#display e1port line-code 1
  ---------------------
  F/S/P   linecode  
  ---------------------
  0/1/1   HDB3      
  ---------------------
huawei(config-if-edt-0/1)#e1port crc4 1 enable
huawei(config-if-edt-0/1)#display e1port attribute 1
  ----------------------------------------------------------
   F/S/P    Signaltype    CRC4    Impedance    Accessmode
  ----------------------------------------------------------

  ----------------------------------------------------------

Configuring the ISDN PRA User Data

This topic describes how to configure the ISDN PRA user data on the H.248 interface (the data must be the same as the corresponding data on the MGC) so that the ISDN PRA user can access the network to use the ISDN PRA service.

Prerequisites

The ISDN PRA service board must be inserted into the planned slot correctly and the board must be in the normal state.

Default Configuration
Table 1-49 lists the default settings of the attributes of the ISDN PRA user. When configuring these attributes, you can modify the values according to the service requirements.
Table 1-49 Default settings of the attributes of the ISDN PRA user

Parameter

Default Settings

Priority of the ISDN PRA user

cat3: (common user)

Flag of reporting the UNI fault of the ISDN PRA user

Disable

Sub-channel active mask of the ISDN PRA user

255.255.255.255

Threshold for the number of auto recoveries from deterioration faults

20

Procedure

  1. In global config mode, run the esl user command to enter the ESL user mode.
  2. Run the mgprauser add command to add an ISDN PRA.

    • When iid-map in the iua-linkset add command is configured to 1, interfaceid must be configured and be different from the interfaceid of other users in the same link set.
    • The terminal ID of an ISDN PRA user must be unique.
    • Each ISDN PRA user occupies 32 terminal IDs. You need to input only the first terminal ID when adding an ISDN PRA user. If the MG interface does not support the terminal layering function, plus (or minus) at least 32 to (or from) the terminal ID of the previous ISDN PRA user when adding an ISDN PRA user, and use the result as the first terminal ID of the current ISDN PRA user.
    • If the MG interface supports the terminal layering function, the terminal ID cannot be configured when an ISDN PRA user is added on the MG interface. The system automatically allocates a terminal ID for the user.

  3. Run the display mgprauser command to check whether the ISDN PSTN user data is the same as the data plan.
  4. (Perform this step when you need to modify the attributes of an ISDN PRA user.) Run the mgprauser attribute set command to configure the attributes of the ISDN PRA user.
  5. (Perform this step only after you modify the attributes of the ISDN PRA user.) Run the display mgprauser command to query whether the configured attributes of the ISDN PRA user are the same as the data plan.

Example

Assume that the MG interface ID is 0, link set ID is 0, IUA port ID is 0 (iid-map is 1), terminal ID is 223 (does not support the terminal layering function), user priority is cat2, UNI alarm report flag is enable, sub-channel active mask is 255.255.255.255, and the threshold for the number of auto recoveries from L1 is 30. To add such an ISDN PRA user connected to the 0/1/0 port, do as follows:

huawei(config)#esl-user
huawei(config-esl-user)#mgprauser add 0/1/0 0 0 interfaceid 0 terminalid 223
huawei(config-esl-user)#display mgprauser 0/1

(Optional) Configuring the System Parameters

This topic describes how to configure the system parameters including the overseas version flag and message waiting indication (MWI) mode according to the local standards to ensure that the response of the user terminal complies with the local standards.

Procedure

  1. Run the system parameters command to configure the system parameters.
  2. Run the display system parameters command to check whether the system parameters are the same as those in the data plan.

Example

To configure the overseas version flag (system parameter 1) to Hong Kong (parameter value 1), do as follows:

huawei(config)#system parameters 1 1                      
huawei(config)#display system parameters 1
  ----------------------------------------------------------------------------- 
  Parameter name index: 1     Parameter value: 1                                
Mean: Overseas version flag, 0:China, 1:HongKong, 2:Brazil, 3:Egypt,
4:Singapore, 5:Thailand, 6:France, 7:Britain MSFUK, 8:Britain ETSI, 9:Bulgaria,
10:Reserved, 11:Austria, 12:Hungary, 13:Poland, 14:Turkey, 18:Belarus,
20:Germany                                  
  ----------------------------------------------------------------------------- 

(Optional) Configuring the Overseas Parameters

By default, the overseas parameters are configured according to the Chinese standards. In the actual service configuration, the attributes such as the upper and lower thresholds of the flash-hooking duration can be configured according to the local standards to ensure that the response of the user terminal complies with the local standards.

Procedure

  1. Run the oversea parameters command to configure the overseas parameters.
  2. Run the display oversea parameters command to check whether the overseas parameters are the same as those in the data plan.
Example

To set the upper flash-hooking threshold (overseas feature parameter 0) to 800 ms (in compliance with the Hong Kong standard) and the lower flash-hooking threshold (overseas feature parameter 1) to 100 ms (in compliance with the Hong Kong standard), do as follows:

huawei(config)#oversea parameters 0 800
huawei(config)#oversea parameters 1 100
huawei(config)#display oversea parameters
{ <cr>|name<U><0,99> }: 1                                                          
                                                                                
  Command:                                                                      
          display oversea parameters 1                                           
    ----------------------------------------------------------------------------- 
  Parameter name index: 1     Parameter value: 100                               
  Mean: Hooking lower threshold(ms), reference: China:100, HongKong:100
