Introduction
The Cisco MWR 1900 Mobile Wireless Edge Router running Cisco IOS Release 12.2(8) MC2 or a later
Cisco IOS Release 12.2 MC is a networking platform optimized for use in mobile wireless networks. It
extends IP connectivity to the cell site and Base Transceiver Station (BTS), and through a Fast Ethernet
interface to the BTS, provides bandwidth-efficient IP transport of voice and data bearer traffic, as well
as maintenance, control, and signalling traffic, over the leased line backhaul network between the BTS
and leased line termination and aggregation node via compression (cRTP/cUDP) and packet
multiplexing (PPPMux and MLPPP). It supports a limited set of interfaces and protocols, but offers high
performance at a low cost while meeting the critical requirements for deployment in cell sites, including
small size, extended operating temperature range, high availability, and DC input power flexibility.
