Interface or line modules Cisco (line card, interface module) allow you to expand the router or modular platform with the required functionality, including the necessary access ports at speeds 1GbE, 10GbE, 40GbE or 100GbE. Mainly for each series of modular routers or chassis Cisco releases various expansion modules for a certain line of devices, but in most cases, the module can be used in more than one line (for example. interface module Cisco EHWIC-4ESG compatible with routers Cisco ISR G2 1900 series, 2900 series and 3900 series).
depending on the platform, interface module Cisco can support a small number of ports, as is the case with small routers Cisco 1900 series and 48 ports in one module for 7600 series chassis. Interface modules and boards Cisco support many different interfaces and can be used both on the network Ethernet, as well as in other data networks.
