10.3 Q.931 CALL-CONTROL MESSAGES 259Figure 10.3-10. Format of IE.11 (progress indicator). (From Rec. Q.931. Courtesy of ITU-T.)IE.12—Signal (Fig. 10.3-11). This IE allows the network to inform the userabout in-band tones.Signal value:000 0000 (0) Dial-tone on000 0001 (1) Ringing-tone on000 0011 (3) Recorder/congestion-tone on000 0100 (4) Busy-tone on100 1111 (79) Tones offIE.13—Transit Network Selection (Fig. 10.3-12). Specifies the transitnetwork selected for the call. If an ISDN user does not include this IE in theSETUP message for a long-distance or international call, the local exchangeroutes the call to the “normal” (default) interexchange carrier (IXC) of the user,which is stored at the exchange. A user can specify a different IXC for a call byincluding an IE.13 in the SETUP message.Type of network identification:010 National network identification011 International networkNetwork identification plan:0001 Carrier identification code0011 Data network identification codeNetwork identification: A string of IA5 characters.Figure 10.3-11. Format of IE.12 (signal). (From Rec. Q.931. Courtesy of ITU-T.)
260 DIGITAL SUBSCRIBER SIGNALING SYSTEM NO. 1Figure 10.3-12. Format of IE.13 (transit network selection). (From Rec. Q.931, Courtesy ofITU-T.)IE.14—User–User (Fig. 10.3-13). User-to-user signaling is a service offered inseveral countries, but not in the United States. The IE, which can be included inSETUP, ALERT, CONN, DISC, RLSE, and/or RLCOM messages, allows thecalling and called users to send up to 128 octets of information during the setupand release of a connection. The IE is transferred transparently across the network.Protocol discriminator:0000 0000 User-specific coding0000 0010 Information in the form of IA5 charactersUser information: This information is not standardized and has to be prearrangedby individual pairs of ISDN users.10.4 INTRODUCTION TO CALL-CONTROL SIGNALINGThis section begins by outlining a typical sequence of Q.931 messages for a callbetween two users who are served by the same local exchange. It then introducessome ISDN call-control concepts and sets the stage for the additional examples ofSection 10.5.We shall use the message acronyms of Section 10.2.3 and refer to informationelements by their reference numbers. When reading this section, it is helpful tolook up the IE descriptions of Section 10.3.5.Figure 10.3-13. Format of IE.14 (user–user). (From Rec. Q.931. Courtesy of ITU-T.)
