Data Network & Internet
The UMnet Backbone Network interconnects numerous networks and facilitates collaboration between users of those networks.
On-Campus Backbone Connections
Provides a LAN attachment to an interconnecting Backbone for departments on the University of Michigan-Ann Arbor campus.
Off-Campus Backbone Connections
Provides an attachment to the UM FDDI Backbone for off-campus LANs for departments of the University of Michigan-Ann Arbor campus. Connections such as T1 and ISDN are available.
U-M Backbone Interconnect Network Connections
The UMBIN provides an attachment for the primary backbones on the Ann Arbor campus. The UMBIN attaches the backbones to each other and to the Internet.
Internet2
Through ITCom, the University of Michigan has established a billing arrangement with two cable companies for their cable modem service: Comcast and Charter Communications. This arrangement allows U-M departments to pay for cable modem service for their faculty or staff using an internal account. The arrangement does not include scheduling an installation, performance, or repair/outages.
Coaxial Cable
Fiber Optic Cable
Access to interbuilding fiber can be acquired by renting access to ITCS's extensive fiber plant and/or having intrabuilding fiber installed.
Station Cable
Installation of station cables in virtually any campus location, for use by voice and/or data services. This will be needed if there isn't a communications outlet in a location where service is required.
Circuits
ITCom installs and maintains many various circuits for use by departmental data network and telephone services.
Data Center Network Attachment
Units may install and operate their own machines in the Arbor Lakes data center.
Access to the space is provided by ITCS/UMCE. Machines in the data center attach
to an ITCom LAN which is attached to the UMnet backbone. ITCom leases attachments
to this local area networkto UM units.
LAN Installation & Upgrade
This is a Local Area Network (LAN) installation service. ITCom installs shared, switched and fast ethernets. Look at this if you want to build your own departmental LAN or need an upgrade.
Maintenance & Repair - Service Agreements
Through this service a department can have their network maintained. ITCom will first benchmark a departmental network and then maintain it so it continues to function at that level. Software upgrades to hardware, monitoring and hardware repair are included. Hardware upgrades are not included.
Network Evaluation & Benchmark
This service evaluates the state of a departments LAN. Recommendations can then be made to bring the network up to a healthy state.
This is a service that allows machines to get their IP addresses and other information assigned by the network themselves rather than having to have this done manually by a person. Basically, it allows a network administrator to attach a computer to a U-M network and then have that computer figure out its own configuration for connecting to the Internet automatically.
IT Communications provides the Northwood DSL Network Service for residents of the University's Northwood complex (Northwood I-V).
If you have questions regarding a current or upcoming project, you can contact the appropriate ITCom Field Coordinator. They can address your concerns related to the installation of voice, video, and data service.
For students living in University Housing, the University provides high-speed Internet access in residence halls via ResComp, and in Northwood Apartments via the Northwood DSL Network Service.
Students, staff, and faculty members who live in group houses or in private residences can obtain high-speed Internet access through any of a number of commercially available Internet service providers.
The Network Operations Center (NOC) is comprised of a team of network specialists who monitor networks, including UM backbones and departmental LANs, and provide first-level troubleshooting for customers' networks 24 hours a day, 365 days a year.
U-M Virtual Private Network
The U-M VPN is available to all University of Michigan students, faculty, and staff who have a valid U-M uniqname and umich password. It provides an encrypted VPN for all network computing needs.
