DATA SHEET

CISCO SECOND-GENERATION 1- AND 2-PORT
T1/E1 MULTIFLEX TRUNK VOICE/WAN INTERFACE CARDS

This flexible, multiservice solution supports multiple data, voice, and integrated data and voice applications, facilitating the

migration from data only or channelized data and voice to packet voice solutions and simplifying deployment, management,

and sparing.

INTRODUCTION

The Cisco

Second-generation 1- and 2-port T1/E1 Multiflex Trunk Voice/WAN Interface (MFT VWIC2s) support data and voice applications on

the Cisco 1721 (data only), 1751 and 1760 Modular Access Routers, the Cisco 2600XM Multiservice Router, the Cisco 2691 Multiservice Platform,

the Cisco 3662 Telco Versatile DCN Access Platform, the Cisco 3725 and 3745 Multiservice Routers, and the Cisco 1841 (data only), 2801, 2811,

2821, 2851, 3825, and 3845 Integrated Services Routers. The Cisco MFT VWIC2 combines WAN-interface-card (WIC) and voice-interface-card

(VIC) functions to provide unparalleled flexibility, versatility, and investment protection through its many uses. Customers who choose to integrate

data and voice in multiple steps preserve their investment in a T1/E1 WAN interface because the Cisco MFT VWIC2 cards can be reused in packet

voice applications. The 2 port T1/E1 MFT VWIC2 is shown below.

The Cisco MFT VWIC2 interface cards add numerous improvements over the Cisco 1- and 2-port T1/E1 Multiflex Voice/WAN Interface Cards

(MFT VWICs). The MFT VWIC2 cards have an onboard slot for a Cisco MFT Dedicated Echo Cancellation (ECAN) Module (part number EC-

MFT-32 or EC-MFT-64), offering an enhanced echo-cancellation capability for demanding network conditions. The T1/E1 MFT VWIC2 cards

support both T1 and E1, providing additional flexibility in configuring the Cisco MFT VWIC2s for supporting T1, fractional T1, E1, and fractional

E1 for both voice and WAN applications. All MFT VWIC2 modules now 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 Cisco 2-port MFT VWIC2s

also can enable each port to be clocked from independent clock sources for data applications. This independent clocking capability is not supported

for voice applications or with the Cisco ATM/Voice Advanced Integration Modules (part number AIM-ATM, AIM-VOICE-30, AIM-ATM-VOICE-

30).

The Cisco MFT VWIC2 cards can either be inserted into the WIC, VWIC and high-speed WIC (HWIC) slots on the supported Cisco 1721, 1751,

1760, 1841, 2600XM, 2691, 2801, 2811, 2821, 2851, 3662, 3725, 3745, 3825, and 3845 access routers, or they can be used in the VWIC slot(s) on

the Digital T1/E1 Packet Voice Trunk Network Module (NM-HDV), IP Communications High-Density Digital Voice/Fax Network Modules (NM-

HDV2), IP Communications High-Density Digital Voice NM with 1 T1/E1 (part number NM-HDV2-1T1/E1), IP Communications High-Density

Digital Voice NM with 2 T1/E1 (part number NM-HDV2-2T1/E1), 2 slot IP Communications Enhanced Voice/Fax Network Modules (NM-HD-

2VE), 2 WAN Card Slot Network Module (NM-2W), 1 10/100 Ethernet 1 4/16 Token Ring 2 WAN Card Slot NM (NM-1FE1R2W), 1 10/100

Ethernet 2 WAN Card Slot Network Module (NM-1FE2W-V2), and 2 10/100 Ethernet 2 WAN Card Slot Network Module (NM-2FE2W-V2) when

used with a supported access router.
