Connecting Cisco Voice Network Modules to the Network

Note For the NM-HD-1V, NM-HD-2V, and NM-DS-2VE network modules, DSPs are on-board and are not

field-replaceable units (FRUs).

Note The NM-HD-1V, NM-HD-2V, and NM-HD-2VE network modules replace the NM-1V and NM-2V

network modules. The NM-1V and NM-2V network modules are still available for use on Cisco 2600

series, Cisco 3600 series, and Cisco 3700 series routers.
