6-2 Chapter 6 Introduction Emulex Frame Relay software is a streamlined, connection-oriented fram e- mode 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 telecom munications protocol standard sp[...]

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 Rela[...]

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 t[...]

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 i ndependent develope r applications) requiring wide area connectivity Emulex X.25 uses the 1984 CCITT X.25 Recomm endation, which defines the interaction b[...]

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 ci rcuit 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 statistic[...]

7-4 Chapter 7 Logical channels differentiate the virt ual circuits supported by the packet level. Each packet is associated with a logical channel which is mapped to the appropriate destination of the virt ual circuit. Multiple connections are provided simultaneously by multiplexing virtual circuits over the access line. This enables a more effecti[...]

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 conn[...]

7-6 Chapter 7 Maximum Frame Size (Nl) - Determines the maximum frame size (in octets) allowed to be received on the li nk. It is automatically configured from the packet size and maxim um packet size information. Retry Count (N2) - Determines the m aximum number of tim es a frame should be retransmitted because of the expiration of the Retry Timer [...]

X.25 Configuration 7-7 When establishing a connection to an X.25 network, you must set this parameter to DTE (the default valu e) 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 corre[...]

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 I[...]

X.25 Configuration 7-9 Tw o 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, Low est 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 va[...]

7-10 Chapter 7 Reverse Charging Calls - Offers the equivalent of a collect call. It is allowed on a per-call basis and is speci fied in the Call Request packet by the calling DTE.
