A WAN interface card, or WIC is specialized network interface card (NIC),
which allows devices to connect to the WAN. (NIC provides an interface device
and a local network). WIC has an interface Channel Service Unit / Data Service
Unit (CSU / DSU) that enables the board to colloque with a router that is
connected to the WAN. The term is used especially in conjunction with equipment
constructed by Cisco Systems.

WIC is a type of circuit board of standard
size to fit an expansion slot on the router. WIC is available to the ordinary
telephone service (POTS), wireless networks, and ownership of cable networks. A
WIC is crafted for appliance with all accustomed network protocols. data rates
of 56 kbps for dial-up connections to the higher speed WAN acceptance. The
methods include half-duplex, full duplex, synchronous and bisync.
Composition
of second-generation 1 - and 2-port T1/E1 Multiflex Trunk (MFT) voice / WAN
interface cards (Multiflex VWIC) that support voice and data applications in
Cisco Multiservice Routers. Multiflex ...
... VWIC combines WAN Interface Card (WIC) and
voice interface card (VIC) functionality, the following improvements.

In

VWIC2-2MFT-T1/E1 Multiflex Trunk Voice/WAN Interface Card there is support
for T1 and MFT cards E1-T1/E1 VWIC2 mean greater flexibility in configuring the
MFT VWIC2 cards support T1, Fractional T1, E1 and fractional E1 for both voice
and WAN applications. ability to fall and integration in all versions - All
modules now include fall VWIC2 MFT employability and multiplexing, which
eliminates external third party CSU / DSU multiplexer and inclusion and
integration. Capacity Building for synchronization.

In

VWIC2-2MFT-G703 Multiflex Trunk Voice/WAN Interface Card the 2-port MFT
VWIC2s can enable each port by a controlled clock source of computer
applications. This independent clock is not supported for voice applications and
not supported by the module-ATM-VOICE-30 AIM. Dedicated echo cancellation option
- MFT VWIC2s a seat aboard Multiflex trunk dedicated echo form (EC-MFT-32 and
EC-MFT-64), which provides greater responsiveness for accurate network
conditions.
Switched Ethernet is a layer of adequate data link and physical
layer commission for local area networks. In the upper layers, Internet Protocol
(TCP / IP) has become the norm. attenuated LANs as a rule consist of one or more
switches assembled together, often at least one router is associated to a cable
modem, DSL modem or Internet connection.

Large LAN characterized by the
appliance of duplicative links with switches using the spanning tree protocol to
avert loops, their aptitude to administer different types of traffic through the
quality of service (QoS) and traffic separate virtual LANs. LAN also assumes a
large variety of network devices such as switches, firewalls, routers, load
balancers and sensors.

LAN can have relationships with other LANs via
leased lines, leased services, or by tunneling over the Internet using VPN
technologies. Depending on how relationships are assured and secure in a LAN and
the distance, a local network is also categorized as a metropolitan area network
(MAN) or wide area networks (WANs). The network topology describes the layout
address of connections between devices and network segments. The most common
types are bus topology, ring, star bus, star and multilayers.
