29、 this information model, the actual implementation may affect on which layer 2 link attributes concerning frequency hopping and front-end switch are sent. Equipment used to implement frequency hopping can be common to several radio carriers or located inside one radio carrier. Front-end switch is ha
30、ndled by Site Manager, therefore all Abis Channel attributes must be sent to it. Those attributes that need a link identifier in BSC data structures are marked with an asterisk (*). 5.2. Addressing of Objects It is a GSM requirement that the BSC is capable of operating with BTSs from different manuf
31、acturers. So, it is necessary that the differences between BTSs, as seen by the BSC, are minimised as much as possible. This is achieved by addressing NM messages by the Managed Object Class and Managed Object Instance. There must be in the BSC an object model with a complete layer 2 link descriptio
32、n for each object instance in the BTS (e.g., Baseband Transceiver 1, Baseband Transceiver 2, Baseband Transceiver 3, .). When a message has to be sent to an object instance this mapping is used to find the correct link. The first connection shall be established from the BTS site by using a (semi-) p
33、ermanently programmed default TEI. Subsequent to the establishment of the default connection to the site, further initial connections to other objects shall be established using TEls provided by procedures in Subclause 6.3.1. Possible additional TEls to an object already having an initial TE1 are as
34、signed with a GSM 12.21 message found in Subclause 6.3.1. through an already assigned signalling link. Object instances also have a layer 3 address. The instance number is used to address the object instance. Regardless of whether the layer 2 address uniquely identifies the object instance or not, t
35、he layer 3 address must also be provided so that it can be used by management agent to determine which object instance is being addressed. This combination of layer 2 and layer 3 addressing accommodates BTS sites with either single or multiple physical links. Specific equipment configuration informa
36、tion is manufacturer dependent. However, for interoperability, link configuration, default TE1 assignment and instance numbering must be known by both manager and agent. This, as well as supported functions, is considered as Shared Management Knowledge. ETSI ETS*300*623 76 3400855 0131475 969 Page 1
37、5 ETS 300 623: June 1996 (GSM 12.21 version 4.5.4) 5.3. State Management of Objects State management in this ETS is generally in line with CCITT X.731. How state values are applied is explained below. CCITT X.731 states that “the management state of a managed object represents the instantaneous cond
38、ition of availability and operability of the associated resources from the point of view of management.“ In this ETS there are two different factors (CCITT X.731 defines usage state in addition to these two) that are considered to affect the management state of a managed object. They are: - - Admini
39、stration: permission to use or prohibition against using the resource, imposed through the management services; Operability: whether or not the resource is physically installed and working. This ETS defines the following three state management attributes to represent the management state of a manage
40、d object: - Administrative state; - Operational state; - 5.3.1. Administrative State Availability status (this elaborates the operational state). Administrative states of the managed objects can be controlled only -y the BSC. In fact, the control of resource usage comes from the MSC). Setting the ad
41、ministrative state of a Channel to locked means that it has to discontinue all transmission and reception of information on Air interface and all telecommunication (traffic and signalling) information transmission on A-bis interface. Setting the administrative state of a Radio Carrier to locked mean
42、s that it has to discontinue all RF emission on Air interface for the frequencies it is responsible. Setting the administrative state of a Baseband Transceiver to locked means that it has to discontinue all telecommunication tramissions and the Channels which are affected should indicate that they a
43、re Disabled or Degraded. Setting the administrative state of a BTS to locked means it has to discontinue all RF emission on all Radio Carriers and all telecommunication transmissions on all Channels of all Baseband Transceivers, .e., Radio Carriers, Channels and Baseband Transceivers are in Disabled
44、, Dependency state. The administrative state at the BTS site is also used to provide information e.g., for a local MMI user at a BTS site. The locked state of a 12.21 managed object means that BSC has disconnected all the calls that go through the resource that is represented by the managed object.
45、No new traffic is connected through this resource any more. The shutting down state means that no new traffic is connected through this resource any more. The on-going calls remain. The unlocked state means that new traffic is allowed through the resource represented by the managed object. ETSI ETS*

Operational State and Availability Status CCIlT X.731 gives the following definitions for the values of the operational state attribute: - - disabled: the resource is totally inoperable and unable to pr
47、ovide service to the user(s); enabled: the resource is partially or fully operable and available for use. In this ETS the value Disabled represents the following conditions that the resources could have: - - power is turned off: - failure has occurred; - hardware or software is not installed: radio
48、parameters has not yet been set by elementary procedures, therefore, the resource is off line. The availability status elaborates the operational state attribute. In this ETS the following values are used (availability status is a set value): In test: The resource is undergoing a test procedure. Fai
49、led: The resource has an internal fault that prevents it from operating. The operational state is disabled. Power off: The resource requires power to be applied and is not powered on. The operational state is disabled. Off line: The resource requires some manual and/or automatic operation(s) to be performed to make it available for the use. Dependency: The resource cannot operate because some other resource on which it depends is unavailable. The operational state is disab
