Carrier Ethernet services are defined from a subscriber perspective (and hence they re also referred to as retail services ). As shown in Figure 2.6, the MEF has developed an Ethernet Services Definition Framework that defines any Carrier Ethernet service in terms of a predefined Ethernet service type. Each of these Ethernet service types (described next) are, in turn, defined by a set of Ethernet service attributes that define its capabilities. Some of these attributes apply to the UNI, others to the EVCs, and still others to both the UNI and EVCs associated with the service type. Specific parameters associated with each of these Ethernet service attributes ultimately define the Ethernet service fully. This seemingly complicated approach is also illustrated in Figure 2.6, but it will become clearer when real-life examples are discussed later in the chapter. It is helpful to remember that every service is defined in terms of a service type and invariably has a set of UNI and EVC attributes13 that will uniquely define it. Before delving into the specific service types (which are defined in terms of the Ethernet service attributes), it is useful to understand these service attributes.

Supervision information, such as on-hook or off-hook, refers to the state of the interface. Control information, such as hold or forward, can refer to a variety of valueadded features, such as 800 or free phone services. The major contribution of the Intelligent Network and ISDN beyond older networks is primarily in the area of control. Addressing and alerting are familiar and therefore somewhat self-explanatory concepts. When a call is placed, the signaling system is responsible for:

longitudinal frame behavior is offered by moment connections between the ends of beams and pinned connections with the structural approach slab resting on grade.

This document should be reviewed and updated twice per year by the BC committee. Additionally, the 50 Tier 1 employees should receive formal training annually to keep them updated with policies and procedures. Tier 2 employees should receive a yearly e-mail or other document to keep them updated on the procedures.

In order for two applications running on two different computer systems to communicate with one another (such as a database application executing on a server and a

The original version of C included a feature that is sometimes described as the implicit int rule (also called the default to int rule). This rule states that in the absence of an explicit type specifier, the type int is assumed. This rule was included in the C89 standard but has been eliminated by C99. It is also not supported by C++. Since the implicit int rule is obsolete and not supported by C++, this book does not use it. However, since it is still employed by many older C programs, it is still supported by C++ Builder for C programs and a brief discussion is warranted. The most common use of the implicit int rule was in the return type of functions. Years ago, many (probably, most) C programmers took advantage of the rule when creating functions that returned an int result. Thus, years ago a function such as
