1 GLOSSARY June 21, 2007 A AC automatic callback adapter An application program that implements an external interface to allow access to the Cisco BTS Softswitch. ADI ADM AIN AMA ANI ANNC Annex E Annex F ANS application AR ASPC AT ATM B Activation, Deactivation, and Interrogation Administration, Diagnostic, and Maintenance Advanced Intelligent Network. A telephone network architecture that adds advanced computer intelligence to the telephone system. AIN supports advanced telecommunications features such as voice recognition. Automated Message Accounting automatic number identification. The number transmitted through the network that identifies the calling party. Technically, it is a Common Channel Interoffice Signaling (CCIS) parameter referring to the number transmitted on an out-of-band basis through an SS7 signaling network identifying the calling party's telephone number. Also known as a calling party number (CPN). announcement Connection Over UDP Relates to sending signaling over UDP (User Data Protocol) for quicker call establishment. UDP does not replace TCP/IP. Annex E optimizes the gatekeeper-routed call model. Inter-Domain Communications A domain is several zones grouped together. Inter-domain communications focuses on address resolution between domains. Announcement server A collection of one or more programs that provide congruent functionality to accomplish a task within the scope of the Cisco BTS Softswitch. automatic recall Analog Stored Program Control Switch access tandem Asynchronous Transfer Mode GL-1

RAS is defined in the H.225 ITU-T Recommendation. RAS is used to communicate between gateways, endpoints, and gatekeeper. RAS is also used to communicate between two gatekeepers. Registration: A function of the gateway to the gatekeeper to inform the gatekeeper about information pertinent to the gateway. The information is: E.164 number assigned to the POTS port of the gateway, H.323 Alias, and technology prefix. Admission: A function of the gateway to request the gatekeeper for E.164 number to IP address translation. Status: A function of the gateway to inform the gatekeeper about an active call.
