The Q reference point is defined in ISO\/IEC 11579-1. Service specifications are produced in three stages and according to the method specified in ETS 300 387. <\/p>\n<p>This International Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage 2 specifications in ISO\/IEC 21407. The signalling protocol for SS-SD operates on top of the signalling protocol for basic circuit switched call control, as specified in ISO\/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementary services specified in ISO\/IEC 11582. <\/p>\n<p>This International Standard also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-SD and other supplementary services and ANFs. This International Standard is applicable to PINXs which can interconnect to form a PISN.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Information Technology &#8211; Telecommunications and Information Exchange Between Systems &#8211; Private Integrated Services Network &#8211; Inter-Exchange Signalling Protocol &#8211; Simple Dialog Supplementary Service<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/csa\/\"><b>CSA<\/b><\/a><\/td>\n<td>2004<\/td>\n<td>33<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":514917,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[599,2674],"product_tag":[],"class_list":{"0":"post-514904","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-33-040-35","7":"product_cat-csa","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/514904","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/514917"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=514904"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=514904"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=514904"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
