27、onnecting analog lines and ISDN primary and basic accesses, in order to emulate PSTN/ISDN services over IP. 1.1 Differences between H.248 ARGW Profiles Version 1 and Version 2 The differences between both H.248 profile versions are detailed in annex A. Summary list of differences: 1) Package usage d
28、etails (see clause 5.14.2). 2) IUA/SCTP encapsulation for Q.921 p-/f-type frames in IP domain (see clause 7.3.2). 3) Additional V5 support (see clause 7.4). 4) Adaptive-rate based MGC overload control (see clause 8.1.2). 5) Real time statistics reporting (see clause 8.4). 2 References References are
