  • Page 11: Principles Of Operation

    FT may change its location or a PT may be stationary mounted. A HW 86012/22 can be configured either as PT or as FT. For the most simple case, a point- to-point connection between two modules, one side must be configured as PT and the other...

  • Page 12: Connections

    Different types of connections are defined by the DECT standard. E.g. a data connection differs very much from a voice connection. Most available DECT devices only support voice connections. This explains, why it is usually not possible to send data from a HW 86012/22 to a consumer type of DECT “base station”.

  • Page 13: Firmware Description

    500 kbit/s per radio cell. Overview All functions of the HW 86012/22 are enabled by suitable firmware. This includes the processing of the DECT communication protocols, the control of interfaces and other features.

  • Page 14: Mode Selection

    3.1.2.1 Selection by Reset Sequence See HW 86012/022 Integration Manual for details on the reset sequence. If the download mode is entered, the download protocol is invoked. See section 5.5. When the configuration mode is entered it will be executed using a baud rate of 9.600 bd.

  • Page 15: System Security

    In compliance with GAP the firmware supports on-air subscription of PTs, meaning that the subscription information is exchanged over the air interface. Through on-air subscription the HW 86012/22 can be subscribed to DECT equipment of other manufacturers. Offline subscription is an alternative subscription procedure that does not require any information exchange over the air interface.

  • Page 16: Dect Identities

    According to the DECT standard a FT may own multiple ARIs, which are called PARI (primary ARI), SARIs (secondary ARIs) and TARIs (tertiary ARIs). In accordance with the GAP service profile (EN 300 444) HW 86012/22 supports one ARI which is then the PARI. SARIs and TARIs are not supported.

  • Page 17: Pt Related Identities

    PT in a DECT network. The DECT standard allows other IPUI types and allows multiple IPUIs at a PT. HW 86012/22 (as PT) does not use IPUI types other than N. However HW 86012/22 (as FT) is interoperable with PTs that use a different IPUI type.

  • Page 18: Subscription Identities

    FIRMWARE DESCRIPTION System Security 3.2.1.3 Subscription Identities During the subscription procedure defined in the DECT standard a UAK (user authentication key) is created. This key represents a pair (FT, PT) and must be known by PT and FT since it is used for the authentication procedure. When the FT requests an authentication from a PT it tests the correct UAK.

  • Page 19: Easysubs

    FIRMWARE DESCRIPTION System Security 3.2.2 EasySubs EasySubs is a powerful technique for handling of subscription information in the FT. Conventional FT implementations include a table of all subscribed PTs with their UAKs. Since memory is limited, the FT may only support a very limited number of subscriptions. The EasySubs technique avoids storage of UAKs in the FT but provides an efficient means for on-demand computation of UAKs from other information already available.

  • Page 20: On-Air Subscription Of Portable Terminals

    FIRMWARE DESCRIPTION System Security 3.2.3 On-Air Subscription of Portable Terminals The firmware supports on-air subscription according to GAP. In on-air subscription the public information is transmitted by the FT over the air interface. The on-air subscription procedure is described below. Step 1 Enable on-air subscription by setting SIAIR ON.

  • Page 21: Data Mode

    FIRMWARE DESCRIPTION Data Mode Data Mode The data mode is used to transfer user data from the module's RS-232 interface to the DECT network and vice versa. Several modes of operation are available to fit different applications. 3.3.1 Point to Point Operation •...

  • Page 22: Point To Multipoint Networking Operation

    Data Mode 3.3.3 Point to Multipoint Networking Operation These option are based upon CLDPS radio protocol. Typically, a set of HW 86012/22 modules (configured as PT) is used, operating to a wireles infrastructure consisting of HW 8614 Ethernet base stations connected to an Ethernet based loca area network (LAN).

  • Page 23: Tcp/Ip Data Mode

    CLDPS network to the LAN and WAN to any TCP/IP based server. There, the serial data stream can be terminated in a TCP socket connection. The HW 86012/22 module may be configured as a TCP/IP server (listening port) or client (active port) as required by the application. Protocols implemented in the software stack include TCP, IP, ARP, ICMP and DHCP.

  • Page 24: Swap Data Mode

    Just plain user data are transferred on the interface. As a couple of HW 86012/22 clients may need to be multiplexed on the server side, a dedicated protocol is used internally in the modules: SWAP (Secure Wireless Access Protocol) is based on PPPoE (RFC 2516) and LAP and allows for protected data link with adequate performance on the DECT / CLDPS link and the wired LAN.

  • Page 25: Ppp Data Mode

    Data Mode 3.3.3.3 PPP Data Mode The HW 86012/22 module may be configured to operate a PPP server. The host application‘s PPP client may initiate a PPP connection to the module, having the opportunity to use it’s own IP address or to trigger the module to receive an IP address from the network using DHCP.

  • Page 26: Usage Of Rs-232 Interface

    Whenever HW 86012/22 deactivates CTSO (CTSO goes high), the host shall stop output of data. HW 86012/22 tolerates up to 16 bytes being output by the host after deactivation of CTSO has occurred. The module activates CTSO again as soon as it is ready to accept more data from the host.

  • Page 27: Interworking Of Modem Lead Signals

    FIRMWARE DESCRIPTION Data Mode 3.3.4.3 Interworking of Modem lead Signals In transparent data mode the modem lead signals are available on the DTRI, DSRO, DCDIO and RIIO pins. DTRI, DCDIO and RIIO signals are interworked to the peer module. DTRI is always interworked to DSRO.

  • Page 28: Outgoing Call, Pt Interface

    FIRMWARE DESCRIPTION Data Mode 3.3.4.4.1 Outgoing call, PT interface In order to request a call, the PT-side host shall activate the DTRI signal (i.e. pull it to low level). An established call is indicated to the host through an activation of the DSRO signal. The DSRO signal remains active for at least 10ms.

  • Page 29: Incoming Call, Pt Interface

    FIRMWARE DESCRIPTION Data Mode 3.3.4.4.3 Incoming call, PT interface A call request from a FT is signalled to the PT-side host by an activation of the DSRO signal. If the PT is in DCE mode, the call request is also signalled by an activation of the RIIO output signal (see SPECC command).

  • Page 30: Call Release, Pt Interface

    DSRO signal from the HW 86012/22 is inactive the call has been released. The HW 86012/22 shall indicate a call release from the FT or the network to its host by deactivating DSRO for at least 5 seconds. After this time has expired the host must deactivate DTRI during the following second unless a new call shall requested.

  • Page 31: Data Transmission

    FIRMWARE DESCRIPTION Data Mode 3.3.4.5 Data Transmission This section describes the operational rules for data transmission in transparent data mode. 3.3.4.5.1 Alignment with call control Any data received from the host through the RS-232 interface while there is no call established will be discarded by the module.

  • Page 32: Example: Transparent Multipoint Mode

    FIRMWARE DESCRIPTION Data Mode 3.3.4.6 Example: Transparent Multipoint Mode In a configuration with 1 FT and 4 PTs the command SPMP ON on FT-side leads to the transparent multipoint mode (see SPMP command): FT to PT: FT sends 26-byte data packets to each connected PT. PT to FT: Each PT sends 26-byte data packets to FT.

  • Page 33: Modem Lead Signals In Cldps Mode

    Data Mode 3.3.4.7 Modem Lead Signals in CLDPS Mode The HW 86012/22 module provides a fully featured RS232 serial interface. The modem lead signals have enhanced functionality, depending on the data mode selected, the state of client or server configuration (SPTCPMODE resp. SPTM) and the configuration of enhanced call control (SPECC).

  • Page 34: Configuration Mode

    4. The protocol continues at step 1. By successful completion of step 3 any modified configuration data has been saved in the non-volatile memory of the HW 86012/22. 3.4.3 Leaving the Configuration Mode The configuration mode is terminated by a reset sequence or by the EXIT configuration command.

    APPENDIX Protocol Data Mode 5.1.2 Usage of RS-232 Interface 5.1.2.1 Connection of the interface In protocol data mode only the interface signals TXDI and RXDO are used. The modem lead signals DTRI, DSRO, DCDIO, and RIIO are not used. However the status of the lead signals can be signalled over the protocol data channel.

  • Page 94: Address Field (Addr)

    SAPI Call Handle: This 7-bit wide binary field is a unique identifier of a connection. Call handles are allocated by the HW 86012/22 during call establishment and are used throughout the call for addressing a specific connection. SAPI: This 2-bit wide field contains higher layer information. It identifies the service access point on the upper interface of the LAP protocol.

  • Page 95: Data Field (Data)

    Protocol Data Mode 5.1.3.4 Data field (DATA) The variable length Data field is used to carry a LAP frame. The HW 86012 supports Data field of up to 26 bytes length. The length of the Data field is not explicitly signalled but derived at the receiver from the frame boundaries detected by flag fields.

  • Page 96: Transparency

    APPENDIX Protocol Data Mode 5.1.4.2 Transparency The byte value 0x7E is reserved for the flag field of the HDLC frame (see section 5.1.2). If any of the address, data or FCS fields contains a byte with value 0x7E, it must be removed prior to transmission in order to avoid misinterpretation as flag field by the receiver.

  • Page 97: Lap Protocol Overview

    APPENDIX Protocol Data Mode 5.1.5 LAP Protocol Overview LAP (link access protocol) is a widely spread protocol for safe data transmission. It provides end-to-end error correction and flow control for a data link. Each data link requires its own instance of LAP. There exist multiple variants of LAP which differ in some details of their frame structures and their ways to establish a connection.

  • Page 98: Lap Information Elements

    APPENDIX Protocol Data Mode 5.1.6 LAP Information Elements A LAP frame consists in a control byte and an optional information field. LAP frame CONTR Information There are different frame types, information frames (I-frames) and supervisory frames (RR-, RNR-, REJ-, SABM- and UA-frames). CONTR: The 1-Byte wide control field defines the frame type and, depending on the frame type, other information element.

  • Page 99: Information Frames

    APPENDIX Protocol Data Mode 5.1.6.1 Information frames When data is transmitted over LAP, it is segmented into I-frames. Each I-frame is identified by a sequence number. This number is incremented for every new I-frame. When an I-frame is repeated, e.g. due to a detected transmission error, it retains its original sequence number.

  • Page 100: Information Elements In The Addr Field

    M: The more bit indicates that a LAP frame is split on multiple HDLC frames and that another segment follows. HW 86012 does not support LAP frame split. The more bit is always 0. C/R: The command / response bit allows the distinction between command and response frames.

  • Page 103: Sender Procedures

    APPENDIX Protocol Data Mode 5.1.7.5 Sender procedures Sending I-frames When an I-frame is sent, its sequence number (i.e. the value of V(S)) is transmitted in the N(S) field of the control byte. V(S) is incremented directly after the transmission. Timer DLU.04 is started.

  • Page 104: Receiver Procedures

    APPENDIX Protocol Data Mode 5.1.7.6 Receiver Procedures Receiving I-frames When an I-frame is received the following procedure applies: If the self busy condition is set, the frame is discarded. Otherwise the receiver checks if N(S) is equal to V(R). In this case the frame is accepted and its content is passed to the higher layer.
