Cisco Terminal Server

Terminal  Server 

A terminal or comm server commonly provides out-of-band access for multiple devices. A terminal server is a router with multiple, low speed, asynchronous ports that are connected to other serial devices, for example, modems or console ports on routers or switches.
The terminal server allows you to use a single point to access the console ports of many devices. A terminal server eliminates the need to configure backup scenarios like modems on auxiliary ports for every device. You can also configure a single modem on the auxiliary port of the terminal server, to provide dial-up service to the other devices when network connectivity fails.

async network modules that are inserted into routers, providing the same access server/terminal server capabilities but in a card. Those cars are called NM-16A and NM-32A cards and you must have a router that has a NM (network module) slot 
these modules use the 68-pin OCTAL Cables such as the CAB-OCTAL-ASYNC
