Class PDUAbstract

constructor

• new PDU(address: string | SCA, options?: PDUOptions): PDU

  Constructs a Protocol Description Unit (PDU) instance.

  Parameters

  • address: string | SCA

    The address as a string or SCA instance
  • options: PDUOptions = {}

    An object containing optional parameters for the PDU instance

  Returns PDU

Abstracttype

address

• get address(): SCA

  Represents the address of the recipient.

  Returns SCA

  The current address as an SCA instance

dataCodingScheme

• get dataCodingScheme(): DCS

  Retrieves the Data Coding Scheme (DCS) of the SMS message.

  The DCS indicates the data type of the message content (e.g., text, UCS2, etc.) and may influence how the message is displayed on the recipient's device.

  Returns DCS

  The current data coding scheme as a DCS instance

protocolIdentifier

• get protocolIdentifier(): PID

  Retrieves the Protocol Identifier (PID) of the SMS message.

  The PID is used to indicate interworking and teleservices. It determines how the message should be processed by the receiving entity.

  Returns PID

  The current protocol identifier as a PID instance

serviceCenterAddress

• get serviceCenterAddress(): SCA

  Returns the Service Center Address (SCA) of the SMS message.

  The Service Center Address is used by the GSM network to know where to send the SMS.

  Returns SCA

  The current service center address as an SCA instance

setAddress

• setAddress(address: string | SCA): PDU

  Sets the address of the recipient.

  This method updates the address for the PDU. It accepts either a string or an SCA instance. If a string is provided, it converts it to an SCA instance.

  Parameters

  • address: string | SCA

    The new address, either as a string or an SCA instance

  Returns PDU

  The instance of this PDU, allowing for method chaining

setDataCodingScheme

• setDataCodingScheme(dcs: DCS): PDU

  Sets the Data Coding Scheme (DCS) for the SMS message.

  Adjusting the DCS can change how the message content is interpreted and displayed by the recipient's device. This method accepts only DCS instances to ensure proper format.

  Parameters

  • dcs: DCS

    The new data coding scheme as a DCS instance

  Returns PDU

  The instance of this PDU, allowing for method chaining

setProtocolIdentifier

• setProtocolIdentifier(pid: PID): PDU

  Sets the Protocol Identifier (PID) for the SMS message.

  This method allows customization of the message's PID, which can affect delivery and processing. Only PID instances are accepted to ensure correct format and compatibility.

  Parameters

  • pid: PID

    The new protocol identifier as a PID instance

  Returns PDU

  The instance of this PDU, allowing for method chaining

setServiceCenterAddress

• setServiceCenterAddress(address: string | SCA): PDU

  Sets the Service Center Address (SCA) for the SMS message.

  This address is crucial for routing the message through the GSM network. The method accepts either an SCA instance directly or a string that will be converted into an SCA.

  Parameters

  • address: string | SCA

    The new service center address, either as a string or an SCA instance

  Returns PDU

  The instance of this PDU, allowing for method chaining
