(Lieberman 21). The practice began with the development of India's technology universities and training infrastructure. The programming skills needed in software development are readily available in countries like India and China. A company can hire well-trained, professionally educated IT workers from India at a significant savings over hiring IT workers in the west (Lieberman 16). A technology worker costs some five times less in India than in America, which is the primary incentive to outsource work. The global availability of digital internet connections, combined with communications tools such as email, instant messaging, faxes, videoconferences, and cellular phones has empowered the foreign worker to provide services that do not necessarily require direct physical contact (Lieberman 15).

Conversely, suppose that there are faults in PNNI in a multiple node network. Since it is a hierarchical protocol, we can group the nodes into two peer groups. Each peer group then behaves like a single node. These two connected peer groups behave like our previous two nodes, so the faults will manifest in this two-node network as well. Therefore, we confine ourselves to a two-node network for our verification and testing study. The tool set we use is PROMELA, SPIN  , and PITHIA  for modeling, simulating, and generating tests for the protocols, respectively.

Advantages of T1 Each T1 is equivalent to 24 separate circuits between two sites, an advantage for T1 because multiple lines and multiple-site networks are expensive and hard to manage. The end-user equipment at each site can be PBXs, videoconferencing systems, imaging systems, or host computers. T1s connecting two PBXs are called tie trunks. For some old PBXs that cannot directly receive a T1 signal, a T1 line must first be terminated at a channel bank. Analog lines are subject to noise and signal deterioration, and equipment that is used for reconstructing the analog signal cannot make them suitable for data transmission, because analog lines amplify both original signal and noise.
