Product Details


NIM-1CE1T1-PRI is a Cisco Multiflex Trunk Voice and WAN network interface module for ISR 4000

series. Cisco® Fourth-Generation 1-, 2-, 4-, and 8-Port T1/E1 Multiflex Trunk Voice and WAN Network

Interface Modules (NIMs) support data and voice applications on the Cisco 4000 Integrated Services

Routers (Figure 1). 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

superior 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. These

NIMs are not supported with Cisco 2900 and 3900 Integrated Services Routers.


Key Features of Cisco 4000 Series Integrated Services Router T1/E1 Voice and WAN Network

Interface Modules include:


●   Basic T1/E1 data: The MFT versions act as WICs, supporting T1, fractional T1, E1, and fractional

E1. To simplify remote management, these modules integrate a fully managed DSU/CSU for T1

deployments and a fully managed DSU for E1 deployments.


●   E1/G.703 data: In addition to the basic T1/E1 data support, the CE1T1 versions also support

structured G.703 with G.704 framing and unstructured E1 (G.703) applications.


●   T1/E1 packet voice: All the modules support packet voice applications by providing T1, fractional

T1, E1, and fractional E1 connections to private branch exchanges (PBXs) and central offices, thereby

enabling new services and reducing voice and fax toll charges. An additional onboard PVDM4 is required.

Also, each NIM has its own PVDM4, so each module can be connected to a different service provider

with no single clock domain restriction.


●   Mixed data and packet voice: All the modules can simultaneously support both data and voice,

reducing the complexity and number of network components and facilitating a graceful migration to

bandwidth-efficient packet voice.


●   Mixed data and packet voice with drop and insert: You can deploy all the modules as T1/E1 drop

-and-insert multiplexers with integrated DSUs/CSUs, reducing the complexity of the network and the

cost of the central-office ports by efficiently combining time-division multiplexing (TDM) voice (PBX),

IP voice, and data on the same trunks.
