The network includes one MUXserver 320 Remote Terminal Server which is connected to the host computer system via an Ethernet Local Area Network (LAN). The network supports up to 32 active remote asynchronous terminals or printers, via synchronous links and remote terminal multiplexers as follows: · Up to two synchronous links are supported by the MUXserver 320 - one at up to 64Kbps and one at up to 19.2Kbps. · Up to three DECmux 300 remote terminal multiplexers may be connected, via modems, in a daisy-chain fashion to each synchronous link. The total MUXserver 320 network is limited to six DECmux 300s. · Depending on its particular model and configuration, each DECmux 300 may have 4, 8, 16 or 32 asynchronous ports. · The total number of asynchronous devices attached to the MUXserver 320 network is limited only by the available asynchronous ports on the DECmux 300s. · The number of active users is limited to 32. · The number of sessions is limited to 128. The network connects each remote terminal to the host LAN with access to certain LAT and INTERNET services offered by the LAN. The MUXserver 320/380 Network Reference Manual describes the features of the MUXserver 320 remote terminal network. The MUXserver 320 product family consists of two variants of the MUXserver 320 and eight variants of the DECmux 300 which are listed in Table B-1. Introduction 1-1 1.2 Typical MUXserver 320 Network Configuration Figure 1-1 illustrates the configuration principles of a MUXserver 320 network. It shows: · One MUXserver 320 connected to either an ULTRIX load host or VMS load host via an Ethernet local area network, · A console terminal connected to the MUXserver 320's Supervisor port, · Up to two synchronous links serviced by the MUXserver 320, · Up to three DECmux 300s connected, in daisy-chain fashion, to each synchronous link. Thus the total MUXserver 320 network is limited to six DECmux 300s. Many different configurations for the network are possible but all are subject to the following configuration constraints: · There can be only one MUXserver 320 in a MUXserver 320 network, but there may be many MUXserver 320s on a single LAN. · The maximum number of DECmux 300s in a MUXserver 320 network is six. · The DECmux 300s are connected to the MUXserver 320 via synchronous links either directly or indirectly via daisy-chaining the DECmux 300s. · A maximum of three DECmux 300s can be daisy-chained together. · The MUXserver 320 Network must be a linear network - it must not contain circular synchronous link paths. As a result, there is only one synchronous link path between any DECmux 300 and the MUXserver 320 and between any two DECmux 300s. · Synchronous links must not have a propagation delay of more than 100mS. · Because they introduce excessive delays which adversely affect network performance, satellite links on synchronous links are not supported. 1-2 Introduction Figure 1-1: MUXserver 320 Network Configuration Principles 1.3 The MUXserver 320 The MUXserver 320 is shown in Figure 1-2. The MUXserver 320 may be installed in a variety of environments, including offices, computer rooms and satellite equipment rooms. The MUXserver 320 can be placed on a desk or table, or can be mounted in a standard rack cabinet. Digital Equipment Corporation can supply a wall/partition mounting bracket to mount the unit directly onto an office wall or to suspend it from partitioned office walls. This bracket must be ordered separately. See Appendix B for ordering information. All controls, indicators and connectors used to install and operate the MUXserver 320 are located on the rear panel of the unit, as shown in Figure 1-3.

Console connector This 6-pin Modified Modular Jack (MMJ) connects a console to the MUXserver 320's Supervisor Port for installation, configuration, or troubleshooting. ------------------------------------------------------------ 1.4 Connecting the MUXserver 320 Connections can be made to the MUXserver 320 as follows: · Ethernet Port A transceiver cable connects the MUXserver 320 to the Ethernet network via the Ethernet port (see Figures 1-4 and 1-5). The transceiver cable can be connected to: * Another transceiver cable section, * A DELNI Local Network Interconnect, * A transceiver on a standard Ethernet coaxial cable for Digital baseband networks, or * A ThinWire Ethernet Station adaptor (DESTA) on a ThinWire Ethernet coaxial cable (see Figure 1-5). Figure 1-4: Standard Ethernet Coaxial Cable Connection 1-6 Introduction Figure 1-5: ThinWire Ethernet Coaxial Cable Connection · Synchronous Links A synchronous link on the MUXserver 320 network typically includes the following components (see Figure 1-6): * An adaptor cable which connects the synchronous port to a synchronous modem. The correct adaptor cable must be used to select the appropriate interface standards for connection to the modem. The adaptor cables are 60cm (2ft) long and are designed to be used with the corresponding extension cables. Such cabling is required at both ends of the synchronous link. Refer to Appendix B for ordering information. * A synchronous modem for interfacing between the adaptor cable and the leased communications line. Modems are required at each end of the communications line. Link speeds supported by the network depend on the interface selected. Table 1-4 shows the link speeds supported for the various interfaces. Local synchronous link connection is also possible by using a RS-422-A/Null Modem unit interconnect cable (BC19Y-10). This cable directly connects two synchronous links and no leased communications line is required (see Figure 1-6). If a connection longer than 3m (10ft) provided by the BC19Y-10 is required, a custom cable will have to be made.
