What are the advantages of this over a leased line installation? What is the difference between connectionless and connection-oriented networking? Solution 4. The Michigan Terminal System: The Michigan Terminal System (MTS) is one of the first time-sharing computer operating systems. Developed in 1967 at the University of Michigan for use on IBM S/360-67, S/370 and compatible mainframe computers, it was developed and used by a consortium of eight universities in the United States, Canada, and the United Kingdom over a period of 33 years (1967 to 1999). The software developed by the staff of the University of Michigan\'s academic Computing Center for the operation of the IBM S/360-67, S/370, and compatible computers can be described as a multiprogramming, multiprocessing, virtual memory, time-sharing supervisor that handles a number of resident, reentrant programs. There is a large subsystem, called MTS (Michigan Terminal System), for command interpretation, execution control, file management, and accounting. There are Michigan terminal system are using a several Modems and POTS connections. Advantage of this over a leased line installation: Michigan Terminal Systems are used a leased line is Private circuit. A leased line is a private bidirectional or symmetric telecommunications line between two or more locations provided in exchange for a monthly rent. Sometimes known as a private circuit or data line in the UK The Michigan Terminal System are many leased networks. Leased lines are used to build up private networks, private telephone networks (by interconnecting PBXs) or access the internet or a partner network (extranet). · Site to site PBX connectivity · Site to network connectivity · International private leased circuit Site to site data connectivity: Terminating a leased line with two routers can extend network capabilities across sites. Leased lines were first used in the 1970s by enterprise with proprietary protocols such as IBM System Network Architecture and Digital Equipment DEC net, and with TCP/IP in University and Research networks before the Internet became widely available. The other Layer 3 protocols were used such as Novell IPX on enterprise networks until TCP/IP became ubiquitous in the 2000s. Today on words point to point data circuits are typically provisioned as either TDM, Ethernet, or Layer 3 MPLS. Site to site PBX connectivity: Terminating a leased line with two PBX allowed customers to by-pass PSTN for inter-site telephony. The customers to manage their own dial plan (and to use short extensions for internal telephone number) as well as to make significant savings if enough voice traffic was carried across the line Site .
