Cisco Cisco NM-1V One Voice Fax Interface Card Slot Network Module Guide De Dépannage

  

Cisco Voice Network Modules provide enterprises, managed service providers, and service
providers the ability to directly connect the public switched telephone network (PSTN) and legacy
telephony equipment to existing Cisco 2600, Cisco 3600, and Cisco 3700 routers. The NM-1V and
NM-2V carrier modules support Voice Interface Cards (VICs) to provide this connectivity.

Note: The NM-1V and NM-2V carrier modules do not support WAN Interface Cards (WICs), which
are data-only interface cards. The "V" in the product name indicates that these are voice carrier
modules. The WIC carrier module product numbers are NM-1W and NM-2W.
