A small discrepancy has come to our attention: If the intent is to change the value of bit M from 0 to 1, then the description should change too from non-ISDN to ISDN. 6.9.10 Technical Correction Relating to Sending ACM Description: Section C.7.1.3 contains a technical error in the assignment of the values of M, K and I. The corrected text is shown below. [Begin Correction] C.7.1.3 Sending of the Address Complete Message (ACM) Backward call indicators If bit I is 1 0 then: bit K ISDN user part indicator 1 ISDN user part used all the way If bit I is 0 then: bit M ISDN access indicator 01 terminating access non-ISDN [End Correction]

The meaning of bit M whether 0 or 1 is defined by 3.5/Q.763

bit M ISDN access indicator 0 terminating access non-ISDN 1 terminating access ISDN
