The Cisco Fourth-Generation T1/E1 Multiflex Trunk Voice and WAN Network Interface Modules (NIMs) support data and voice applications on the Cisco 4451-X integrated services routers. These cards combine WAN-interface-card (WIC), voice-interface-card (VIC), ISDN Primary Rate Interface (PRI), dial-access integration, and channelized-data (CE1T1) functions to provide unparalleled flexibility, versatility, and investment protection through their many uses. Customers who choose to integrate data and voice in multiple steps preserve their investment in a T1/E1 WAN interface. The T1/E1 modules contain an onboard Cisco Packet Voice Digital Signal Processor Module 4 (PVDM4) slot, which requires a fourth-generation PVDM4 module. A PVDM4 on the T1/E1 module is necessary for the voice features. The PVDM4 also provides for echo cancellation of up to 128-ms echo-tail length for demanding network conditions.

You can insert the Cisco T1/E1 NIMs into the NIM slot on the supported Cisco 4000 Integrated Services Routers (ISRs). In addition to the features listed in Table 1, these modules support both T1 and E1, providing additional flexibility for supporting T1, fractional T1, E1, and fractional E1 for both voice and WAN applications simultaneously. All modules include the drop-and-insert multiplexing capability, which eliminates costly external third-party channel service units/data service units (CSUs/DSUs) and drop-and-insert multiplexers.
The fourth-generation Cisco T1/E1 NIMs add improvements over the Cisco Second- and Third-Generation T1/E1 Multiflex Trunk Voice and WAN Interface Cards (MFT VWIC2s and VWIC3s, respectively). The fourth-generation T1/E1 modules enable each port to be clocked from an independent clock source for data applications. Voice applications can now be clocked independently from data applications, with all ports for voice applications clocked from a single source.
The T1/E1 modules contain an onboard Cisco Packet Voice Digital Signal Processor Module 4 (PVDM4) slot, which requires a fourth-generation PVDM4 module. A PVDM4 on the T1/E1 module is necessary for the voice features. The PVDM4 also provides for echo cancellation of up to 128-ms echo-tail length for demanding network conditions. Refer to Table 2 for all configuration options offered with the modules.
These fourth-generation modules also provide increased port density per chassis compared to the Cisco Integrated Services Routers Generation 2 (ISR G2) platform.
