Connecting Asynchronous Network Modules to Asynchronous Devices Chapter 5 Connecting Serial Network Modules Connecting Asynchronous Network Modules to Asynchronous Devices An asynchronous network module provides two or four 68-pin receptacles. Each receptacle connects to asynchronous devices by means of an octal cable that has a 68-pin plug at the module end and eight connectors at the network end, one for each of the eight EIA/TIA-232 serial ports. Depending on the type of cable, the network end consists of either RJ-45 connectors or male DB-25 connectors. RJ-45-to-DB-25 adapters are also available. Ports are numbered from right to left and from bottom to top, as labeled on the module rear panel. (See the "Asynchronous Network Module Interface Numbering" section on page 5-6.) Octal Cables Octal cables are not provided with the network module. For ordering information, see the "Obtaining Technical Assistance" section on page xi. Use an octal cable, and adapters if necessary, to connect each of the module's 68-pin receptacles to one or more asynchronous modems, terminals, or other devices. (See Figure 5-1.)

The cables connect the network module to a patch panel or one or more asynchronous modems, terminals, or other devices. (See Figure 5-2.)
