Introduction

MTA48WR Wireless ADSL2+ Router is a DSL broadband access device which allows ADSL connectivity while providing 802.11g wireless LAN capabilities for home or office users. It supports ADSL2/ADSL2+ and is backward compatible to ADSL, even offers auto-negotiation capability for different flavors (G.dmt, G.lite, or T1.413 Issue 2) according to central office DSLAM’s settings (Digital Subscriber Line Access Multiplexer). Also the feature-rich routing functions are seamlessly integrated to ADSL service for existing corporate or home users. Now users can enjoy various bandwidth-consuming applications via MTA48WR Wireless ADSL2+ Router. Maximum Rate: 24 Mbps for downstream and 1.2 Mbps for upstream
