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 Unstructured 2nd Generation.
This Cisco VWIC2-1MFT-G703 is designed to work with the
following platforms: Cisco 2600XM series, Cisco 2691, Cisco 2800
series, Cisco 3662 (Telco models), Cisco 3700 series, and Cisco
3800 series.
The second-generation 1- and 2-port T1/E1 multiflex trunk (MFT)
voice/WAN interface cards (multiflex VWICs) support data and
voice applications in Cisco multiservice routers. The multiflex
VWIC combines WAN interface card (WIC) and voice interface card
(VIC) functionality to provide the following improvements:
• Support for both T1 and E1—T1/E1 MFT VWIC2 cards provide
additional flexibility in configuring the MFT VWIC2 cards by
supporting T1, fractional T1, E1, and fractional E1 for both
voice and WAN applications.
• Drop and insert capability on all versions—All MFT VWIC2
modules now include the drop and insert multiplexing capability,
which eliminates external third party CSU/DSUs and drop and
insert multiplexers.
• Enhanced clocking capabilities—The 2-port MFT VWIC2s can enable
each port to be clocked from independent clock sources for data
applications. This independent clocking capability is not
supported for voice applications and not supported with the
AIM-ATM-VOICE-30 module.
• Dedicated echo cancellation option—MFT VWIC2s have an onboard
slot for a multiflex trunk dedicated echo cancellation module
(EC-MFT-32 and EC-MFT-64), offering an enhanced echo
cancellation capability for demanding network conditions.
