ISDN can be divided into two distinct functional areas: 1. Signaling 2. Transport of user data ISDN uses out-of-band, message-oriented signaling to control everything regarding a call. In message-oriented signaling, every operation, from telling the system the phone is off-hook to disconnecting the call, is performed by sending messages back and forth. The signaling channel then assigns separate channels to transport the

Weathering steel: Using ASTM A242, A588 or A709 W grade steel does not require painting, except at the ends. Special steel: Using special chemical composition steel or with special heat treatment, such as quenched and tempered plate (usually A514 or A517 grade). Hybrid steel section: This is used to describe a section, which is composed of more than one type of steel (e.g., web is composed of grade 50W steel and the anges are composed of 70W). Type 4 Aluminum, wrought iron, or cast iron. Wrought iron and cast iron were commonly used before 1900. Type 5 Stone or brick masonry. 2. Selection of modern materials: A choice can be made for arriving at optimum solution for the use of available construction materials. Steel versus concrete: Structural steel has the advantage of being a permanent material with repetitive uses extending over decades. When recovered from the demolition of a disused bridge, it is salvaged and sent to steel mills and foundries for re-rolling. With the expansion in transportation systems, there are supply shortages, resulting in higher price as the demand for steel increases. Recent trends are for greater use of precast prestressed concrete girders in small and medium span ranges, although steel girders are applicable to any span length. HPS 70W steel welded girders are increasingly being used for long spans. Both steel and reinforced concrete are essential materials for bridge construction as indicated by the use of steel in the form of steel reinforcing bars, prestressing strands, rolled steel joists, or welded plate girders. Epoxy coated reinforcing steel bars Substructure rebars are generally plain uncoated bars. Galvanized steel rebars are used in marine environments. Both epoxy coated and galvanized steel bars are more expensive than plain bars. While local bond properties between concrete and uncoated bars is known, tests need to be performed to determine local bond of different types of chemical used in coatings. Modern concrete materials Composites, ber reinforced polymer concrete, and exodermic decks are being successfully used. Recycling of construction materials Good quality aggregate has the potential to be cleaned and reused for all types of concrete construction. Recycled concrete aggregate from debris can be washed and reused. So far the practice has been to use the debris in land lls and to some extent in pavement construction. Normal weight concrete Lightweight concrete High performance concrete High performance steel Aluminum Glue laminated timber: Glulam hardwood bridges are economical for small spans. The following precautions are also applicable to timber bridges: Timber friction piles can be damaged while driving in rm ground. Timber pile piers in rivers should not be subjected to debris accumulation. Timber bridges are posted for low speed.

Research and development (R&D) covers a large area of testing. Testing at this stage is usually manual and extremely rigorous and exhaustive, concentrating as it does on a complete understanding of the component/PCA/NE under test. Broadly speaking, two types of testing occur, functional and parametric. The parametric tests (pulse mask analysis, bit error rate tests, etc.) usually are confined to the early development stages of a product, i.e. the design of specific circuits, PCBs, and basic ASICs. A synchronous tester required in this area usually is a parametric tester with some (limited) ability to construct and transmit synchronous signals. In addition, some simple alarm generation also might be necessary. Two types of R&D functional testing can be identified, leading-edge and steadystate. The leading-edge tester deals with the standards as they evolve, providing the new services as soon as they are defined. For this type of investigation it is necessary that all the bytes in the frame structure can be accessed, altered, and tested. The ability to perform rigorous and exhaustive tests on all parts of the structure is vital in leading-edge R&D applications, where new capabilities are constantly being addressed. Figure 30.11 shows a typical instrument used for leading-edge design, the HP 75000 Series 90 SDH/SONET analyzer. Based on the VXI standard, the instrument is modular, flexible, and capable of accessing all the EOC bytes. In addition, it has sophisticated stressing and capture capabilities that facilitate the rigorous testing required. The user of steady-state R&D testing tends to be behind the evolving standards, concentrating on the well-established aspects of the standards, building second-generation equipment that often is cheaper and/or more compact than the leading-edge or firstgeneration devices. Cost then starts to become a more important factor in the choice of instrument. The range of bytes that might need to be accessible usually is a small, well-defined subset of the entire structure, so a less sophisticated tester probably is called for. Often the steady-state user is designing gear in an area where the standards are well-defined and the behavior of the protocol is understood; the designer is looking for a good source of synchronous signals to do the basic day-to-day testing on an engineer s bench. Typically the steady-state design lab will have access to a high-end or leading-edge instrument for final detailed testing.
