Infrastructure Design
The University of Maryland Academic Telecommunications System (UMATS)
provides internet, library, and interactive video services to all
University System of Maryland institutions (USM). The UMATS backbone
consists of a DWDM fiber interconnection between College Park,
University of Maryland Baltimore County, University of Maryland at
Baltimore, and the William Donald Schaffer Building. From these
sites, sonet (OC-3) and TDM (DS-3 and T1) circuits fan out to various
other sites. The DWDM ring provides high bandwidth for the USM
institutions in the Baltimore-DC corridor and redundant access for all
UMS institutions to the internet links contracted by UMATS. The DWDM
ring also supports the developing Internet 2 service as well as a
variety of research and production services for UMATS' partners and
clients. The State of Maryland and the Maryland Department of
Transportation have provided the fiber between Baltimore and College
Park that makes this robust service possible. UMATS, through regional
hubs at USM institutions, is also able to share at cost-effective
prices access to telecommunication services for University
partnerships with the state's environmental and medical facilities,
K-12 programs, community colleges, 4 year higher educational
institutions, and other state, national, and international educational
partners.
