1-4 Chapter 1 CAUTION: The system must not load any of the following modules: - extended memory managers, such as HIMEM, QEMM, or EMM386. - disk compression utilities, such as Disk Doubler. - any terminate-and-stay-resident (TSR) programs. Verify that the Novell environment meets the following criteria: • NetWare O/S version 3.12 or version 4.1 (Runtime version included with DCP_link). • Novell MultiProtocol Router (Branch Link or Enterprise version) MPR 3.0, (included with DCP_link).
Hardware Configuration Chapter 2 FACTORY DEFAULT SETTINGS ......................................................................2-2 BASE I/O ADDRESS .........................................................................................2-3 HOST INTERRUPT LEVEL (IRQ SETTING)........................................................2-5 DCP286I-SBC ADAPTER CONFIGURATION ..................................................2-6 JUMPER SETTINGS ........................................................................
2-2 Chapter 2 DCP_link features an 80x86 microprocessor based “intelligent” WAN adapter to provide powerful co-processing capabilities. The adapter utilizes 1Mb of on-board shared memory to transfer commands and data to the NetWare server. DMA channels are included to support full-duplex operation. This chapter describes the factory default configuration of the DCP286i/386i/486e and tells how to configure the board for WAN applications.
Hardware Configuration 2-3 NOTE: The Base I/O address and IRQ settings are the same for all adapters. Data Clock Direction, DTE, is correct for all connections except V.35. Other switch or jumper settings unique to an individual adapter type (i.e., DCP286i-SBC, DCP386i, or DCP486e) are detailed in a separate section of this chapter specific to each adapter. Base I/O Address The Base I/O address is selected via switch SW1, which may be labeled CR ADDR (Control Register Address) on some adapters.
2-4 Chapter 2 SW1 - Base I/O Address Settings Figure 2-1 SW1
Hardware Configuration 2-5 Host Interrupt Level (IRQ Setting) The jumper block used to set the IRQ is unique to each adapter type. DCP286i - J13 DCP386i - J6 DCP486e - J11 Refer to the specific adapter section for the location of this jumper. The available IRQ jumper settings are: / IRQ 2 Figure 2-2 Host Interrupt Level Jumper Plug Settings Use one jumper to select the appropriate interrupt level.
2-6 Chapter 2 DCPx86i/e Adapter Configuration The remainder of Chapter 2 is divided into three sections according to adapter type (DCP286i-SBC, DCP386i, or DCP486e). Please refer to the section for the adapter you are installing.
Hardware Configuration 2-7 Figure 2-5 shows the factory default options for the standard adapter configuration. The factory default setting, as shown, calls for jumper blocks to be in place on each jumper, thus enabling each option: Figure 2-5 Factory Default Jumper Block Placement Figure 2-6 - Jumper Block J1 Options Software Compatibility Level Jumper J1:1-2 selects the software compatibility level of the DCP286i-SBC.
2-8 Chapter 2 Control Register 4 Read Option Set Jumper J1 to enable (J1-3 to J1-4 connected) host read access to Control Register 4. Window Group Select The DCP286i-SBC contains memory that is shared by the host. The host software can select the size of the window that is shared using jumper J1:5-6. The factory default setting (J1-5 to J1-6 connected) allows window sizes of 16K, 32K, 64K or 1MB. By removing this jumper, window sizes of 16K, 64K or 128K are made available.
Hardware Configuration 2-9 Setting Data Clock Direction (DTE or DCE) J7, J8, J9 and SW-3 set the synchronous data clock direction (DTE or DCE) for port 1. Jumpers J4, J5, J6 and SW2 set the synchronous data clock direction (DTE or DCE) for Port 2.

NOTE: Jumper block J6 sets the Host Interrupt Level and SW1 sets the base I/O address for the 386 adapter. Reference the beginning of this chapter for details on these settings.
2-12 Chapter 2 Figure 2-12 DCP386i Factory Default Jumper Connections PC I/O Channel Check The factory default setting (J1-2 to J1-3 connected) for the DCP386i provides an interrupt line to the PC for parity errors in the shared memory. This is the I/O Channel Check signal on the PC bus. A parity error may instead interrupt the local processor at level 0 of the local 82C59. This can be done by placing the jumper in the LCL position (J1-1 to J1-2 connected).

6-2 Chapter 6 Introduction Emulex Frame Relay software is a streamlined, connection-oriented framemode data service based on frame-switching /relaying technology--the process of quickly transporting HDLC (High-level Data Link Control) frames through a network. This software is based on Frame Relay, a WAN telecommunications protocol standard specified by the International Consultative Committee for Telegraphy and Telephony (CCITT) and ANSI (American National Standards Institute).
Frame Relay Configuration 6-3 Emulex Frame Relay encapsulates data frames and routes them through the Frame Relay network based on the Data-Link Connection Identifier (DLCI), which identifies the local permanent virtual circuit (PVC) end point of the router. DLCIs are defined through the configuration process or teamed through the Emulex Frame Relay link management protocol. A Frame Relay network has the following characteristics: • Transports frames transparently.
6-4 Chapter 6 The Frame Relay network switch monitors the access rate and size of data frames transferred through the mesh network. The data throughput CIR is guaranteed by the network, but allows for excess bursts (Be) of data not to exceed the access rate (AR) of the connection. The committed burst size (Bc) sets the maximum amount of data that the network agrees to transfer in a specified time period.
Frame Relay Configuration 6-5 communicate with three remote sites using a minimum of 32 Kbps sustained bandwidth, the physical interface must be able to support at least 3 x 32 Kbps = 96 Kbps. You should also consider traffic pattern characteristics (bursty or sustained) when specifying interface speed. Encoding Option - Corresponds to the encoding set on the physical line to which the Emulex Frame Relay router is attached. It can be NRZI (nonreturn to zero inverted) or NRZ (nonreturn to zero).

X.25 Configuration Chapter 7 INTRODUCTION ................................................................................................................7-2 Virtual Circuit Service...............................................................................................................7-3 Logical Channel Numbers .........................................................................................................7-4 Diagramming Your X.25 Network .....................................................
7-2 Chapter 7 Introduction Emulex X.25 software operates in a NetWare server or NetWare router/bridge PC environment and provides services for NetWare products and other applications (including independent developer applications) requiring wide area connectivity Emulex X.25 uses the 1984 CCITT X.25 Recommendation, which defines the interaction between data terminal equipment (DTE) and data circuitterminating equipment (DCE) of a packet-switching network.
X.25 Configuration 7-3 Virtual Circuit Service X.25 uses two mechanisms, providing a logical path between end points, called virtual circuits. A virtual circuit provides a connection-oriented service, similar to that of circuit switching but with the following exceptions: • Limited to a connection between two end points. • Economical statistical multiplexing for establishing a logical path through the network.
7-4 Chapter 7 Logical channels differentiate the virtual circuits supported by the packet level. Each packet is associated with a logical channel which is mapped to the appropriate destination of the virtual circuit. Multiple connections are provided simultaneously by multiplexing virtual circuits over the access line. This enables a more effective use of the access circuit for the available bandwidth and the traffic density for each logical channel.
X.25 Configuration 7-5 Diagramming Your X.25 Network To ensure that all connections to the X.25 network are properly diagrammed, complete these step: 1) Diagram the existing X.25 network showing all router access points and mark the X.25 addresses. 2) Draw each type of connection from the local router to its corresponding partner. For PVC-type connections, show the LCN assigned by the X.25 network service provider and the partner name. For SVC-type connections, list the partner names. Planning Your X.
7-6 Chapter 7 Maximum Frame Size (Nl) - Determines the maximum frame size (in octets) allowed to be received on the link. It is automatically configured from the packet size and maximum packet size information. Retry Count (N2) - Determines the maximum number of times a frame should be retransmitted because of the expiration of the Retry Timer (Tl). A large value for this parameter increases the probability of a correct transfer between the DTE and DCE.
X.25 Configuration 7-7 When establishing a connection to an X.25 network, you must set this parameter to DTE (the default value) if you are connecting to a X.25 service provider. Default Inbound/Outbound Packet Size - The Inbound Packet uses the default packet size for a inbound call unless another packet size is specified. Set this value to correspond to your network subscription.
7-8 Chapter 7 T25 (Data Packet Retransmission Timer) - Specifies the amount of time, in seconds, that the DTE waits for the appropriate acknowledgment after transmitting a data packet. If the T25 timer expires, the packet layer resets the virtual circuit. T26 (Interrupt Timer) - Specifies the amount of time, in seconds, that the DTE waits when an Interrupt Request packet is sent for an interrupt confirmation to be received. If the T26 timer expires, the packet layer resets the virtual circuit.
X.25 Configuration 7-9 Two Way SVC, Number of LCNs - Determines the lowest LCN that can be used for two-way SVCs. This number must agree with your network subscription. Outbound, Lowest LCN - Determines the lowest LCN that can be used for outgoing logical channels for SVCs. The value must be greater than or equal to the Lowest two-way SVC LCNs value plus the Number of two-way LCNs value. Outbound, Number of LCNs - Determines the number of logical channels reserved for outbound-only SVCs.
7-10 Chapter 7 Reverse Charging Calls - Offers the equivalent of a collect call. It is allowed on a per-call basis and is specified in the Call Request packet by the calling DTE. Closed User Group (CUG ) - Allows the configuration of one or more virtual private networks within a larger public network. A user may gather a number of DTEs into a single logical group and restrict the group’s access ability to receive incoming calls or to make outgoing calls to the restricted “open” portion of the network.

7-16 Chapter 7 Inbound Authentication - Toggle between Enabled or Disabled. Restricts incoming calls to authentication. The originator (server ID and address) of each call coming in on the X.25 link is first checked against the Authentication Database before it is given access to the server. Only those calls in the table are accepted. All other calls are rejected. Note: When Inbound Authentication is Disabled, the X.25 link will accept all inbound calls regardless of originating ID or address.
X.25 Configuration 7-17 Configuring the WAN Call Directory The WAN Call Directory is a list of WAN Call Destination configurations you want to use for each virtual circuit. You must create at least one WAN Call Destination configuration for each desired destination. WAN Call Destination configurations contain parameters to be applied by Emulex X.25 software when establishing and maintaining calls to the destination. Two basic types of call configurations are possible: permanent and ondemand.

Press for a list of configured PVC numbers. NOTE: PVC Numbers may only be configured provided the Wan Call Circuit type is Permanent and the X.25 profile for that interface has been defined. The PVC number must match the Logical Channel Number (LCN) assigned by the X.25 network service provider at subscription time.
X.25 Configuration 7-21 This parameter specifies the maximum delay between attempts to establish a connection (the retry interval). The delay is set initially to 8 seconds and increases exponentially until the maximum retry interval is reached. The range of time intervals is 00:00:00 to 23:59:59 (hh:mm:ss). For permanent calls, the default value is 10 minutes (00:10:00). For ondemand calls, the default value is 2 minutes (00:02:00).
