Product
Description: Cisco 1700, 1800, 2600, 2600XM, 2800, 3600, 3700, and 3800 Series Multiflex
Voice WAN Interface Card (VWIC), 1-Port RJ-48 Multiflex Trunk-T1/E1 and Generation.
The Cisco VWIC2 combines 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 VWIC2
cards can be reused in packet voice applications.
T1/E1 Voice: The Cisco 1- and 2- port T1/E1 VWIC2
(voice and WAN) versions act as a VIC, supporting 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.
Mixed Data and Voice: The Cisco VWIC2 interface cards
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.
The Cisco VWIC2 cards can be inserted into the WIC or
high-density WIC (HWIC) slots on the following routers:
- Cisco 1721 Modular Access Router (data only)
