Brief History

This Standard defines a Protocol for Computer-Supported Telecommunications Applications (CSTA) for OSI Layer 7 communication between a computing network and a telecommunications network. This Standard, plus its companion Standard ECMA-179 Services for Computer-Supported Telecommunications Applications, reflects agreements of ECMA member companies on the first phase of standards for CSTA. Additional phases are anticipated. This Standard is based on the practical experience of ECMA member companies and represents a pragmatic and widely based consensus. This Standard takes its direction from Technical Report ECMA TR/52 Computer-Supported Telecommunications Applications.

Adopted as an ECMA Standard by the General Assembly of June 1992.

Usage Note regarding removing Year 2000 (Y2K) risks in the CSTA Phase I and Phase II Protocol Standards 1 January 1999

In both ITU-T Recs. X.208 (ASN.1 1988) and X.680 (ASN.1 1994), the definition of UTCTime, which is used in the CSTA Phase I and Phase II Protocol Standards (ECMA-180 and ECMA-218 respectively), is not Y2K-safe. The Year field (the YY field) is represented by a two-digit string, with no accompanying text mandating a Y2K-safe interpretation. For the CSTA Phase I and Phase II Protocol Standards, the following interpretation of the Year field is mandated :

If the YY component is in the range [00-49], the century is determined to be "20" (i.e. the year is 2000 to 2049);

If the YY component is in the range [50-99], the century is determined to be "19" (i.e. the year is 1950 to 1999).

The risk has been removed in the CSTA Phase III Protocol Standard (ECMA-285) by replacing the references to "UTCTime" with references to "GeneralizedTime", which is Y2K-safe.

Section 1 - General

Scope This Standard specifies application protocol data units (APDUs) for the services described in ECMA-179, Services for Computer-Supported Telecommunications Applications. The field of application of this Standard is the interconnection of switches and computers in a private telecommunications environment. Section 2 (clause 5 to clause 7 inclusive) describes the concepts underlying the Remote Operations model, notation and service. Section 3 (clause 8 to clause 16 inclusive) contains CSTA-specific protocol details and forms the main body of this Standard. The protocol defined in this Standard operates in the context of an application association. It is assumed that such an application association exists via mechanisms that are not defined in this Standard.

Conformance A manufacturer may select any part (one or more operations) of the CSTA Protocol, as specified in this Standard, for implemention on a system. A system is in conformance with one or more of the CSTA operations if those operations are implemented according to the definitions in this Standard. A Protocol Implementation Conformance Statement (PICS) shall be used to specify the operations which are provided by a particular implementation. A PICS shall also specify the parameter options which are used. A system claiming to implement one or more operations specified within this Standard shall comply with the relevant requirements in clauses 5 to 16 inclusive. 2.1

Static requirements A system claiming conformance shall support the transfer syntax (derived from the encoding rules specified in CCITT Rec. X.209) named joint-iso-ccitt(2) asn1(1) basic-encoding(1); for the purpose of generating and interpreting CSTA protocol information as defined by the abstract syntax "CSTA-ASN.1-Object-Descriptor" for the operations supported.

2.2

Dynamic requirements A system claiming conformance shall:

2.3

follow the procedures as specified in this Standard, and in ECMA-179, relevant to each CSTA operation that the system claims to implement, and

ii)

satisfy the definitions, as specified in ECMA-179, relevant to each CSTA service that the system claims to implement.

PICS requirement The following shall be stated by the implementer when defining a PICS corresponding to an application or implementation: i)

which CSTA operations, as defined in ECMA-179, are supported by the system for the particular implementation,

ii)

which optional parameters are supported by the PDUs belonging to the supported operations, and

iii)

the types and ranges of values for all the parameters supported.

A PICS Proforma is given in annex A.

Section 2 - Protocol Structure for CSTA

CSTA service definition model 5.1

CSTA application layer structure The CSTA application layer structure conforms to the model as described in ISO 9545.

5.2

Remote operations The services of CSTA are modelled as Remote Operations as described in CCITT Rec. X.219. Typically, one entity requests that a particular operation be performed; the other entity attempts to perform the operation and responds to the requestor. Consequently the operation of the protocol is an elementary request/reply interaction, supported within the OSI application layer, and carried out within the context of an application-association. For some of the CSTA services, the entity to which the request is sent generates a reply which can indicate success or failure. For these services, CSTA shall adopt the Operations Class 2, defined in Rec. X.219 as: -

Asynchronous, reporting success or failure (result or error).

For some of the CSTA services, the entity to which the request is sent generates a reply which can only indicate failure. For these services, CSTA shall adopt the Operations Class 3, defined in Rec. X.219 as: -

Asynchronous, reporting failure (error) only, if any.

For some of the CSTA services, particularly the ongoing reporting of events, no reply is generated. For these services, CSTA shall adopt the Operations Class 5, defined in Rec. X.219 as: -

Asynchronous, outcome not reported.

The protocol description for the particular service defines the relevant class of the Operation used for that service. CSTA shall correlate the single response, denoting success or failure, with the originating request by using the mechanisms within the ROSE protocol. 5.3

The CSTA service response CSTA employs a generic response mechanism which is, in principle, decoupled from the specifics of the switching activity. The following points describe the operation of the CSTA service response: 1.

Specific services may have an unconfirmed mode where responses to correct requests are not returned.

The server shall check the correctness of the request (e.g. syntactical checks) before issuing the response. Incorrect requests shall result in an error response, even in the unconfirmed mode.

If a response is sent before the action requested by the service is completed (i.e. the response is a service request acknowledgement) event reporting may be used to keep track of the subsequent server activity.

The precise moment at which the response is generated in relation to the switching activity is implementation and service dependent. i)

Some implementations may generate the response after checking the correctness of the request and at the point they initiate the request.

ii)

Other implementations may delay the response until the service has completed (or is guaranteed to complete). In this case, a failure of the switching request will be reflected in the response.

NOTE 1 Irrespective of implementation details, when an operation succeeds the same event reports are generated if the necessary monitoring has been established. As an example, a Held-Event (if selected) is always reported in addition to the response to a successful request (even in those implementations that delay the

-4-

response until the Hold operation was complete). In a given context, and with appropriate monitoring in place, an operation generates the same set of event reports, whether it was invoked manually or with CSTA service requests from the computer. 5.4

Cross referencing of event reports A computer application process may need to cross reference a CSTAEventReport to one of the following: a)

a CSTA Object ID (Call ID or Device ID),

an earlier Monitor request, or

one of many Monitor requests (pertaining to the same CSTA Object).

For the above scenarios the necessary cross referencing function may be fulfilled by use of the parameter "MonitorCrossRefID". The content of MonitorCrossRefID depends upon the context and it may be one of the following: Call ID, StaticDevice ID, or another independently switch-managed static identifier. The independent identifier may have a unique correlation to either: one device, one call, or one monitor request. The switching system limit on the number of monitor requests on one CSTA Object (Call or Device) is an implementation option. This Standard does not stipulate how many monitor requests on one object are to be supported by the switch. If using Static Device or Call identifiers the limit can only be one. 5.5

Handling of private data If an entity receives the parameter CSTAPrivateData, and it can not recognize the information contained, the parameter shall be discarded, and the rest of the message shall be processed.

Interconnection service boundary The protocol in this Standard is an OSI application layer protocol and uses the Remote Operations protocol defined in CCITT Rec. X.229. The Remote Operations protocol assumes certain services are provided by the underlying layers, and these services are also assumed by the protocol for CSTA.

Security This protocol also provides a mechanism for secure transmission of CSTA PDUs as defined in this Standard. The parameters that constitute this secure PDU are imported from ECMA-138.

Section 3 - CSTA Protocol

Association management The protocol in this Standard operates in the context of an application association. It is assumed that such an application association exists via mechanisms not defined in this Standard.

Switching function services This clause defines the protocol for the Switching Function services of CSTA, using ASN.1. Text descriptions of the CSTA services are provided in ECMA-179. The encoding of the protocol is defined in CCITT Rec. X.209 " Specification of basic encoding rules for the abstract syntax notation". NOTE 2 The range of services supported on a particular association is specified in the application context at association time.

Switching function events This clause defines the protocol for the Event services of CSTA, using ASN.1. Text descriptions of the CSTA services are provided in ECMA-179. NOTE 3 The range of services supported on a particular association is specified in the application context at association time. The structure of an event is as described by the remote operation 'cSTAEventReport'. This is a ROSE class 5 operation, which has an argument containing the event type and other information associated with that event. The EVENT macro is used to define events in this standard. This macro provides a shorthand method to define the data types associated with a particular event. Each use of the macro defines (after the EVENTINFO keyword) the data type that replaces the keyword 'ANY' in the cSTAEventReport operation for that particular event value.

Call events Each event contains a ConnectionID which identifies the object of interest. Other parameters may also be used to identify the relevant devices. Events may result from a call interacting with switch features that had been previously set or invoked. These features and their settings may be reflected in an Event as a value of the EventCause parameter.

A.1

Introduction The Protocol Implementation Conformance Statement (PICS) is a statement of which capabilities and options of the protocol have been implemented. The PICS can have a number of uses, including use:

A.2

by the protocol implementor, as a check-list to reduce the risk of failure to conform to the standard through oversight;

by the supplier and acquirer (or potential acquirer) of the implementation, as a detailed indication of the capabilities of the implementation, stated relative to the common basis for understanding provided by the standard PICS proforma;

by the user (or potential user) of the implementation, as a basis for initially checking the possibility of interworking with another implementation (note that, while interworking cannot be guaranteed, failure to interwork can often be predicted from incompatible PICS);

by a protocol tester, as the basis for selecting appropriate tests against which to assess the claim for conformance of the implementation.

Definitions and abbreviations This Standard uses the following terms defined in ISO 9646-1: -

Protocol Implementation Conformance Statement (PICS);

PICS Proforma.

In the "Reference" columns of the body of the PICS proforma, the letter S refers to the CSTA Services standard ECMA-179 and the letter P refers to the CSTA Protocol standard ECMA-180. The following terms are used in the "Status" columns of the body of the PICS proforma: m = mandatory; the capability is required for conformance to the protocol. o = optional; the capability is not required for conformance to the protocol, or is required only within constraints described in dependencies ("if" statements). If the capability is implemented, it is required to conform to the protocol specifications. o.<n> = optional, but support of at least one of the group of options labelled by the same numeral <n> is required. C.<cid> = conditional; the requirement is conditional according to the condition identified by <cid>. <item> = simple-predicate condition, dependent on the support marked for <item>. A.3

Conformance The supplier of a protocol implementation which is claimed to conform to ECMA-180 shall complete a copy of the Protocol Implementation Conformance Statement (PICS) proforma in clauses A.5 to A.14.

A.4

Instructions for completing the PICS proforma The first part of the PICS proforma, the Implementation Identification (clause A.5), is to be completed as indicated with the information necessary to identify fully both the supplier and the implementation. The main part of the PICS proforma (clauses A.6 to A.14) is a fixed format questionnaire divided into subclauses each containing a group of individual items. Answers to the questionnaire items are to be provided in the rightmost column, either by marking an answer to indicate a restricted choice (usually Yes or No), or by checking off all supported values (for parameters with a default).

- 84 -

Each item is identified by an item reference in the first column; the second column title indicates the nature of the table items which follow. The third column contains the references to material that specifies the item in the main body of ECMA-179 and ECMA-180. The remaining columns record the status of the item - whether support is mandatory, optional, or not applicable - and provide space for the answers. Where a service is not supported, any parameters or dependent service components are not applicable. These dependencies are indicated in the status column using the item identifier as a key. It is not necessary to complete items in any subsidiary sections if a "No" response is given to the primary service component. For supported services, a negative response to a mandatory subsidiary item indicates that the service does not conform to ECMA-180, and conformance cannot be claimed for that service.

- 85 -

A.5

Implementation Identification Supplier Protocol Version

First Edition

Date of Statement Contact point for queries about the PICS Implementation Name(s) and Version(s) Other information necessary for full identification - e.g. name(s) and version(s) for machines and/or operating systems; system name(s)

Note A.1 The first five items are required for all implementations; other information may be completed as appropriate in meeting the requirement for full identification. Note A.2 The terms Name and Version should be interpreted appropriately to correspond with a supplier's terminology (e.g. Type, Series, Model).
