Also, in section 4.2.9 in this addendum, a new reason code, 0x02, is added to the values The remainder of TIA/EIA/IS-658 is unchanged. 8 2 NORMATIVECHANGES 9 4.2.6 Optional Interface Status Exchange 10 11 12 Either the BS/MSC or the
15、IWF may initiate an exchange of interface status information during FR SVC establishment (see 4.2.1 or 4.2.3) or at any other time. This involves an exchange of one or more INTERFACE-STATUS segments. 13 During FR SVC establishment, if the receiving entity responds to a SETUP message with a 14 messag

The SETUP message shall include a REASON segment with the REASON-CODE field set to 0x02 and
18、one or more INTERFACE-STATUS segments. The receiving entity should respond to the SETUP message with a RELEASE COMPLETE message that includes a REASON segment with REASON-CODE field set to Ox02 and includes one or more INTEFSACE-STATUS segments. These INTERFACE-STATUS segments shall refer to the sam
