Cisco NIM-16A
Cisco NIM-16A 16-Port Async Serial NIM
The NIM-16A is supported in the NIM slots of all 4000 Series ISR platforms.
The asynchronous interface modules for the 4000 Series ISRs are specifically designed for terminal server use. This capability allows for out-of-band management of console ports, giving the network operator full console access to a network of remote devices from a central location.
The asynchronous interface modules for the Cisco 4000 Series ISRs do not support Serial Line Internet Protocol (SLIP) or Point-to-Point Protocol (PPP). Asynchronous routing and data encapsulation features are thus not supported.
