Connecting Asynchronous Network Modules to Asynchronous Devices
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
Octal Cables
Octal cables are not provided with the network module. For ordering information, see the
Technical Assistance" section on page
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
12-in-1 Smart Serial Cables
The Cisco NM-16A/S network module uses sixteen 12-in-1 Smart Serial cables. The cables connect the
network module to a patch panel or one or more asynchronous modems, terminals, or other devices. (See
