Introduction. HiSpeed WAN Communications Support Overview The HiSpeed WAN Communications kits are a family of components which enable running applications needing a large bandwidth or high performance access to wide area networks. A HiSpeed WAN Comm. kit is composed of: • A multi-channel or mono-channel X.25 adapter. Each channel is customized with a daughter-board and an associated attachment cable, providing thus one of the following physical interfaces, V24/V28, V24/V35, leased X21. • X.
PAGE 14
The figure shows the HiSpeed WAN Comm. software (or bullx25) components: • X.25 protocol and tests which are loaded at bootstrap into the HiSpeed WAN Comm. adapter. • Adapter driver which handles communications between the HiSpeed WAN Comm. adapter micro-code and applications using one of these communications providers: – TCP/IP, – OSI stack, – XX25, – HVX stack. • Configurators for setting up the X.25 adapter and the interface (if TCP/IP) according to the network subscription.
PAGE 15
Chapter 1. X.25 Introduction X.25 Overview The X.25 protocol was first defined at the end of the seventies by CCITT Recommendation X.25. Further revisions of the recommendation were published in 1984 and 1988. The International Organization for Standardization (ISO) has also published the X.25 recommendations as ISO 8208 and ISO 7776. The X.25 protocol is designed to manage communications on a wide area network (WAN).
PAGE 16
DTE and DCE Two types of equipment are used on an X.25 network: • DTE (Data Terminal Equipment) is an equipment which uses the network for communications. A process on this DTE has to communicate with another process running on another equipment. • DCE (Data Circuit-Terminating Equipment) is an equipment which provides access to the network, that is establishes, maintains and ends the connections. Every DTE must have an associated DCE.
PAGE 17
In a direct connection through an X.25 line, the two equipments located at each end of the connection must apply the following rule: one must be declared as DTE type and the other as DCE type. See the figure 4. X.25 Line DTE DCE Figure 4. X.25 Direct Connection : DTE and DCE Network User Address Each X.25 line in an X.25 network is identified by a number called the Network User Address (NUA) which is assigned by the network provider of the X.25 line subscription. While most public networks use the X.
PAGE 18
Figure 5 shows four DTEs connected to an X.25 network. For each of them a defined number of virtual circuits has been subscribed, but not all of these virtual circuits are active. DTE1 has configured four virtual circuits, two of them are active and connected to DTE2, another is active and connected to DTE3, the last is available. DTE4 has configured two virtual circuits, but it is not communicating with any other DTE and both virtual circuits are available. DTE 2 DTE 1 DCE DCE DCE X.
PAGE 19
The X.25 Protocol Layers The X.25 protocol comprises the three lowest layers of the OSI model, as shown in the figure 6: • physical layer, • link layer, • network layer or packet layer. DTE DTE Applications Applications including highest layers including highest layers X.25 Network DCE DCE Packet Layer Packet Layer Packet Layer Packet Layer Link Layer Link Layer Link Layer Link Layer Physical Layer Physical Layer Physical Layer Physical Layer Modem Modem Modem Modem X.25 Line X.
PAGE 20
X.25 Link Layer The link layer is responsible for the reliable transfer of blocks of data across the physical layer. It provides error detection, flow control and sequencing of blocks of data provided by, and delivered to, the network layer. The link layer uses a link access procedure to ensure that data and control information are accurately exchanged over the physical circuit between the DTE and DCE.
PAGE 21
HDLC Frame Types There are three types of frames: Format Commands Information I Supervisory RR Receive Ready RNR Receive Not Ready REJ Reject Unnumbered SABM Set Asynchronous Balanced Mode Responses RR Receive Ready RNR Receive Not Ready REJ Reject DISC Disconnect DM Disconnect Mode UA Unnumbered Acknowledge FRMR Frame Reject Figure 9. HDLC Frame Types Information frames I Information frame transfers user data.
PAGE 22
X.25 Network or Packet Layer The packet layer manages the establishment, maintenance and termination (routing) of connections while providing the upper layer with independence from the data transmission and switching functions used to connect systems. The packet layer protocol specifies how virtual circuits between DTEs are established, maintained and cleared.
PAGE 23
X.25 Packets Types Different types of packet are used for making a call and accepting a call, transferring data and terminating a call. Here is the list of the X.25 packet types; some of them are DTE specific or DCE specific, the others may be generated either by a DTE or by a DCE.
PAGE 24
The figure 11 shows a simple example of transferred packets during a call between two DTEs using a switched virtual circuit (SVC): 1. A makes a call, which B receives. 2. B accepts the call; A receives a call saying the call has been connected. 3. A sends some data, but does not ask for acknowledgment. 4. A sends some more data, which B acknowledges. 5. A clears the call; B receives indication of this and confirms that is has received the indication. 6.
PAGE 25
Brief Explanation of X.25 Packets Call Set-Up and Clearing Packets Call-Request Packet transmitted by a DTE to ask that a connection for a call be established throughout the network. Incoming-Call Packet transmitted by a DCE to inform a DTE that another DTE has requested a call. Call-Accepted Packet transmitted by a called DTE to indicate to the DCE that it accepts the incoming call.
PAGE 26
Restart Packets Restart-Request Packet transmitted by a DTE to request that a link be restarted. Restart-Indication Packet transmitted by a DCE to indicate to a DTE that a restart-request packet has been received. Restart-Confirmation Packet transmitted either by a DCE or a DTE to confirm that the link has been restarted. Diagnostic Packets Diagnostic 1-12 Packet used by a DCE to indicate errors conditions which cannot be indicated by usual indication packets. HiSpeed WAN Comm.

Lowest logical channel number for an incoming SVC Range of possible values: [0] 0 to 4095 Number of logical channels for incoming SVCs Range of possible values: [0] 0 to 1024 on a 4Port HiSpeed WAN Comm. line 0 to 256 on a 1Port HiSpeed WAN Comm.
PAGE 74
The packet level mode is defined by the subscription, it is generally the same value as the frame parameter Type of line. Optional address in call request/accept packet [allow] Modification or not of the addresses in the call-accepted and call-request packets Two possible values: allow Packets are transmitted without any address changes forbid Packets are transmitted with some address modifications.
PAGE 75
The value must be either 0 (meaning that the inactivity timer is disabled) or in the range 1 to 255 (in seconds) Default Attributes for SVCs The default value of an attribute cannot be set higher than the maximum negotiable value for this attribute (see Maximum Negotiable Attributes for SVCs). However, the maximum negotiable value can be increased before a default value is modified. Any attribute value may be modified for an individual call, using the optional facilities in the call-request packet.
PAGE 76
Maximum Negotiable Attributes for SVCs For each way (reception and transmission) of a switched virtual circuit, three attributes have to be configured: packet size defined in bytes packet window number of packets that can be outstanding without acknowledgment throughput class speed at which the packets travel through the network During a connection, there may be, using optional facilities, negotiations concerning flow control (packet size and window) or throughput class in order to use temporary values inst
PAGE 77
Optional Facilities Optional facilities are those which may or may not be offered by the network provider and to which customers choose whether or not to subscribe. The facilities implemented on HiSpeed WAN Comm. adapters refer to these main concerns: – incoming and outgoing data accesses, in general or according to the membership of a Closed User Group, – redirection and retransmission of data, – charging of communications.
PAGE 78
Redirection notification [enable] Indication to a DTE receiving a call whether this one has been redirected. Two possible values: enable disable Call redirection [enable] Redirection of a call to another DTE when the first one is busy or out of order. Two possible values: enable disable Charging information [enable] Retrieval of information in order to compute the billing.
PAGE 79
Flow control negotiation [enable] Possibility for a DTE to negotiate the flow control parameters (packet and window sizes). If the flow control parameters are not present in the call packet, the default values are selected.

Change / Show Incoming Calls Routing Display and/or modification of the routing parameters related to an X.25 line selected from the list. Warning: This facility must be used carefully, the default configuration being valid for most of standard cases. The addressing routing solves possible conflicts between applications using the same SPI (Subsequent Protocol Identifier) on different communications stacks.
PAGE 81
Warning: It is impossible to configure the same address (with the flag set to used) for two different stacks. Example How to manage the coexistence between these two applications: PAD over OSI Stack and Videotext over XPI/XX25 Stack by using the sub-addressing routing.

Problem Solving You can perform these simple tasks: • after having installed and configured a HiSpeed WAN Comm. adapter, in order to check that everything is working correctly, • when an abnormal behaviour of a HiSpeed WAN Comm. adapter is detected, in order to determine which component is out of order or not configured correctly. Refer to Appendix E. HiSpeed WAN Comm. Adapter and Port Numbering, for more information.
PAGE 115
Check Port Status The lsdev command also lists the status of the HiSpeed WAN Comm. ports. The port status must be ’Available’. If the port status is ’Defined’, while the adapter status is ’Available’, it means that the interface daughter-board is not plugged into the corresponding location or is out of order.
PAGE 116
Check Status of the Physical, Frame and Packet Levels The xdmanage command displays the status of layers 1, 2 and 3, that is physical, frame and packet levels, of all the available HiSpeed WAN Comm. lines. #xdmanage Port Physical Layer x25l Connected Frame Layer Connected Packet Layer Connected For each level, the status is indicated: Connected the adapter is connected to the network. Connecting the adapter is trying to establish the connection.
PAGE 117
If the packet level is not connected • Check if the network parameters have been correctly configured. If you are connected to a public network, the configuration must correspond exactly to the subscription parameters. The most important parameter is: – Packet Level Mode [DTE/DCE]. Monitoring of the X.25 Traffic on an Adapter or on a Port If the previous checks have not found the problem, run the xdmonitor tool in extended mode in order to display all the traffic on an adapter or on a specified line.
