NM-16A/S Product Specifications

Cisco Systems Asynchronous/Synchronous interfaces are the most versatile serial connections that Cisco offers. These A/S interfaces support a wide variety of protocols and applications, including WAN concentration, transport of SDLC and Bi-sync data, and asynchronous terminal connections. Cisco announces the availability of the NM-16A/S that has double the interface density of the NM-8A/S.

Common Support Questions
- Q. What versions of Cisco IOS� are required to support the NM-16A/S?
- A. NM-16A/S support is included in 12.2(15)ZJ and the first release of 12.3T. All IOS� 12.4 main line and 12.4T releases support the NM-16A/S. The NM-16A/S is supported in all IOS� feature sets.
- Q. Which router models support the NM-16A/S?
- A. The NM-16A/S is supported in the Cisco 2600XM Series, Cisco 2691, Cisco 2811, Cisco 2821, Cisco 2851, Cisco 3631, Cisco 3660, Cisco 3725, Cisco 3745, and Cisco 3800 Series.
- Q. Why isn't the NM-16A/S supported in the 2600 non-XM models, 3620, 3640, or 3640A?
- A. The 2600 non-XM models and the 3620 do not have enough memory capacity to introduce new hardware or software features.
- Q. How many NM-16A/S Network Modules are supported in each router?
- A. The number of NM-16A/S Network Modules in a router is limited only by the available network module slots.
- Q. What are the maximum speeds supported by the NM-16A/S?
- A. Like the NM-4A/S and NM-8A/S, the NM-16A/S interfaces support a maximum synchronous speed of 128 Kbps, and a maximum asynchronous speed of 115.2 Kbps.
- Q. What is "lead manipulation"?
- A. The NM-16A/S introduces a new feature called "lead manipulation". This allows the user to ignore input signals on the physical interface, view the state of the input signals, and to monitor the transitions of the input signals.
- Q. What are the differences between the NM-4A/S, NM-8A/S, and NM-16A/S?
- A. In order to achieve higher port density, the NM-16A/S uses the Smart Serial connector that is also used on the WIC-2T WAN Interface Card. Thus customers must order Smart Serial cables for use with the NM-16A/S instead of the "5-in-1" cables used on the NM-4A/S and NM-8A/S. The Smart Serial interface supports all of the physical interfaces that are supported by the "5-in-1" interface, plus EIA/TIA-530A.
