Reference Guide for the Model XM128 ISDN Digital Modem Call Control for 1TR6 (Old German ISDN) In order to initiate a 1TR6 ISDN call, two information elements are necessary: • Service indicator, which determines what kind of bearer services are desired. • Destination address, which provides necessary information for the telephone company central office to direct the call to the remote party. Control of Outgoing Service Indicator The outgoing service indicator is assigned when you configure the B channel protocols using the command ATBnn. Because there are a number of combinations of voice or voice-band-data services on the analog adapters, users may want to control the outgoing service indicator themselves for some specific applications. The following information is recommended to configure S104/S107 (service indicator) and S108/ S111 (additional information octet) according to the terminal types: • Service indicator • S107: analog, PHONE 1 • S104: analog, PHONE 2 Addi.
