Information About NM-8AM-V2 and NM-16AM-V2 Network Modules
Two new analog modem network modules, the 8-modem NM and the 16-modem NM, support basic telephone service connections on Cisco 3600 series, Cisco 3700 series, and Cisco 2600XM series routers, and allow:
- Use standard telephone connections on RJ-11 connectors.
- Up to 16 remote analog modem users to connect to a Cisco 2600XM series
- Up to 32 remote analog modem users to connect to Cisco 3725
- Up to 64 remote analog modem users to connect to Cisco 3745
- Up to 96 remote analog modem users to connect to Cisco 3660
Combined with the differentiated services delivered through Cisco IOS software, Cisco 3700 series, Cisco 3600 series, and Cisco 2600XM series routers users have best-of-breed scalability, flexibility, and investment protection, all in cost-effective, multifunctional platforms.
