Connecting Serial Network Modules to a Network 6-5
Asynchronous Network Modules Interface Numbering
Ports are numbered from right to left and from bottom to top, as labeled on the module’s
rear panel. (See the “Asynchronous Network Modules Interface Numbering” section on
page 6-5.)
Octal cables are not provided with the network module. For ordering information, see the
“Cisco Connection Online” section on page xiv.
Use an octal cable, and adapters if necessary, to connect each of the modules’s 68-pin
receptacles to one or more asynchronous modems, terminals, or other devices. (See
Figure 6-1.)

Asynchronous Network Modules Interface Numbering
Certain Cisco IOS configuration commands identify asynchronous ports by an interface
number (or a line number, which is the same as the interface number). The interface number
of a port on a asynchronous network module is related to the slot number where the module
is installed and the unit number of the port in the module.
