60-Channel High-Density Voice Network Module
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.

60-Channel High-Density Voice Network Module
This section describes the 60-channel high-density voice (HDV) network module, shown in Figure 6. When used in conjunction with T1/E1 multiflex trunk interface cards and packet voice digital signal processor modules (PVDMs), this module is also called a digital T1/E1 packet voice trunk network module.
