Application Server (AS) - A logical entity serving a specific RoutingKey. An example of an Application Server is a virtual switch elementhandling all call processing for a unique range of PSTN trunks,identified by an SS7 SIO/DPC/OPC/CIC_range. Another example is avirtual database element, handling all HLR transactions for aparticular SS7 DPC/OPC/SCCP_SSN combination. The AS contains a setof one or more unique Application Server Processes, of which one ormore is normally actively processing traffic. Note that there is a1:1 relationship between an AS and a Routing Key.Application Server Process (ASP) - A process instance of anApplication Server. An Application Server Process serves as an activeor backup process of an Application Server (e.g., part of adistributed virtual switch or database). Examples of ASPs areprocesses (or process instances) of MGCs, IP SCPs or IP HLRs. An ASPcontains an SCTP endpoint and may be configured to process signallingtraffic within more than one Application Server.Association - An association refers to an SCTP association. Theassociation provides the transport for the delivery of MTP3-Userprotocol data units and M3UA adaptation layer peer messages.IP Server Process (IPSP) - A process instance of an IP-basedapplication. An IPSP is essentially the same as an ASP, except thatit uses M3UA in a point-to-point fashion. Conceptually, an IPSP doesnot use the services of a Signalling Gateway node.Failover - The capability to reroute signalling traffic as requiredto an alternate Application Server Process, or group of ASPs, withinan Application Server in the event of failure or unavailability of acurrently used Application Server Process. Failover also appliesupon the return to service of a previously unavailable ApplicationServer Process.Host - The computing platform that the process (SGP, ASP or IPSP) isrunning on.Layer Management - Layer Management is a nodal function that handlesthe inputs and outputs between the M3UA layer and a local managemententity.Linkset - A number of signalling links that directly interconnect twosignalling points, which are used as a module.MTP - The Message Transfer Part of the SS7 protocol.MTP3 - MTP Level 3, the signalling network layer of SS7MTP3-User - Any protocol normally using the services of the SS7 MTP3(e.g., ISUP, SCCP, TUP, etc.).Network Appearance - The Network Appearance is a M3UA local referenceshared by SG and AS (typically an integer) that together with anSignaling Point Code uniquely identifies an SS7 node by indicatingthe specific SS7 network it belongs to. It can be used to distinguishbetween signalling traffic associated with different networks beingsent between the SG and the ASP over a common SCTP association. Anexample scenario is where an SG appears as an element in multipleseparate national SS7 networks and the same Signaling Point Codevalue may be reused in different networks.Network Byte Order: Most significant byte first, a.k.a Big Endian.Routing Key: A Routing Key describes a set of SS7 parameters andparameter values that uniquely define the range of signalling trafficto be handled by a particular Application Server. Parameters withinthe Routing Key cannot extend across more than a single SignallingPoint Management Cluster.Routing Context - A value that uniquely identifies a Routing Key.Routing Context values are either configured using a configurationmanagement interface, or by using the routing key managementprocedures defined in this document.Signalling Gateway Process (SGP) - A process instance of a SignallingGateway. It serves as an active, backup, load-sharing or broadcast1 process of a Signalling Gateway.Signalling Gateway - An SG is a signaling agent that receives/sendsSCN native signaling at the edge of the IP network [11]. An SGappears to the SS7 network as an SS7 Signalling Point. An SGcontains a set of one or more unique Signalling Gateway Processes, ofwhich one or more is normally actively processing traffic.

Or is it at the base of the hand? Is it on the palm-side or back-side? By using precise anatomical terminology, we eliminate ambiguity Anatomical terms derive from ancient Greek and Latin words Because these languages are no longer used in everyday conversation, the meaning of their words does not change Anatomical terms are made up of roots, prefixes, and suffixes The root of a term often refers to an organ, tissue, or condition, whereas the prefix or suffix often describes the root For example, in the disorder hypertension, the prefix “hyper-” means “high” or “over,” and the root word “tension” refers to pressure, so the word “hypertension” refers to abnormally high blood pressure Anatomical Position To further increase precision, anatomists standardize the way in which they view the body Just as maps are normally oriented with north at the top, the standard body “map,” or anatomical position, is that of the body standing upright, with the feet at shoulder width and parallel, toes forward The upper limbs are held out to each side, and the palms of the hands face forward as illustrated in [link] Using this standard position reduces confusion It does not matter how the body being described is oriented, the terms are used as if it is in anatomical position For example, a scar in the “anterior (front) carpal (wrist) region” would be present on the palm side of the wrist The term “anterior” would be used even if the hand were palm down on a table 1/10 Anatomical Terminology Regions of the Human Body The human body is shown in anatomical position in an (a) anterior view and a (b) posterior view The regions of the body are labeled in boldface A body that is lying down is described as either prone or supine Prone describes a facedown orientation, and supine describes a face up orientation These terms are sometimes used in describing the position of the body during specific physical examinations or surgical procedures Regional Terms The human body’s numerous regions have specific terms to help increase precision (see [link]) Notice that the term “brachium” or “arm” is reserved for the “upper arm” and “antebrachium” or “forearm” is used rather than “lower arm.” Similarly, “femur” or “thigh” is correct, and “leg” or “crus” is reserved for the portion of the lower limb between the knee and the ankle You will be able to describe the body’s regions using the terms from the figure 2/10 Anatomical Terminology Directional Terms Certain directional anatomical terms appear throughout this and any other anatomy textbook ([link]) These terms are essential for describing the relative locations of different body structures For instance, an anatomist might describe one band of tissue as “inferior to” another or a physician might describe a tumor as “superficial to” a deeper body structure Commit these terms to memory to avoid confusion when you are studying or describing the locations of particular body parts • Anterior (or ventral) Describes the front or direction toward the front of the body The toes are anterior to the foot • Posterior (or dorsal) Describes the back or direction toward the back of the body The popliteus is posterior to the patella • Superior (or cranial) describes a position above or higher than another part of the body proper The orbits are superior to the oris • Inferior (or caudal) describes a position below or lower than another part of the body proper; near or toward the tail (in humans, the coccyx, or lowest part of the spinal column) The pelvis is inferior to the abdomen • Lateral describes the side or direction toward the side of the body The thumb (pollex) is lateral to the digits • Medial describes the middle or direction toward the middle of the body The hallux is the medial toe • Proximal describes a position in a limb that is nearer to the point of attachment or the trunk of the body The brachium is proximal to the antebrachium • Distal describes a position in a limb that is farther from the point of attachment or the trunk of the body The crus is distal to the femur • Superficial describes a position closer to the surface of the body The skin is superficial to the bones • Deep describes a position farther from the surface of the body The brain is deep to the skull 3/10 Anatomical Terminology Directional Terms Applied to the Human Body Paired directional terms are shown as applied to the human body Body Planes A section is a two-dimensional surface of a three-dimensional structure that has been cut Modern medical imaging devices enable clinicians to obtain “virtual sections” of living bodies We call these scans Body ...GSM Networks: Protocols, Terminology,and Implementation GSM Networks: Protocols, Terminology,and ImplementationGunnar HeineArtech HouseBoston • London Library of Congress Cataloging-in-Publication DataHeine, Gunnar.[GSM—Signalisierung verstehen und praktisch anwenden.

AAbbssttrraacctt Background: The aetiology of osteoporotic vertebral fracture is multifactorial and may be conceptualised using a systems framework. Previous studies have established several correlates of vertebral fracture including reduced vertebral cross-sectional area, weakness in back extensor muscles, reduced bone mineral density, increasing age, worsening kyphosis and recent vertebral fracture. Alterations in these physical characteristics may influence biomechanical loads and neuromuscular control of the trunk and contribute to changes in subregional bone mineral density of the vertebral bodies. Methods: This review discusses factors that have received less attention in the literature, which may contribute to the development of vertebral fracture. A literature review was conducted using electronic databases including Medline, Cinahl and ISI Web of Science to examine the potential contribution of trabecular architecture, subregional bone mineral density, vertebral geometry, muscle force, muscle strength, neuromuscular control and intervertebral disc integrity to the aetiology of osteoporotic vertebral fracture. Interpretation: A better understanding of factors such as biomechanical loading and neuromuscular control of the trunk may help to explain the high incidence of subsequent vertebral fracture after sustaining an initial vertebral fracture. Consideration of these issues may be important in the development of prevention and management strategies.
