our Max calls a customer constantly but doesn't get a connection. I did some D channel analysis and found the following (interesting) game: XMIT: NL: <proto DSS1> <callref caller 012d> <msgtype SETUP> <Bearer Capability, cap Unrestricted digital, mode circuit, rate 64 kbps> <Channel ident, PRI/other, preferred, B channel units, channel #01> <Called party number, type Unknown, plan Unknown, # 0352XXXXXX <Sending complete> RCV: NL: <proto DSS1> <callref callee 012d> <msgtype CALL PROCEEDING> <Channel ident, PRI/other, exclusive, B channel units, channel #01> <for some seconds nothing happens> XMIT: NL: <proto DSS1> <callref caller 012d> <msgtype DISCONNECT> <Cause, loc U, code 10 (16)> RCV: NL: <proto DSS1> <callref callee 012d> <msgtype RELEASE> XMIT: NL: <proto DSS1> <callref caller 012d> <msgtype RELEASE COMPLETE> <Cause, loc U, code 60 (96)> The Max obviously disconnects the call it placed some time before by it- self, and with cause 16 (Normal call clearing). IMHO this is weird. If there really is a timeout because no answer is received for some time, the Max should disconnect (if at all) using cause 102 (timer expiry), but even that is suspicious - usually the Network will disconnect the call sooner or later by itself. After disconnecting, the Max gets a RELEASE without a cause, which causes the Max to respond with RELEASE COMPLETE and cause 96 (mandatory information element missing). After this, the game starts from the beginning. Can anyone interpret this ? Is it a normal feature of the Max to dis- connect its own calls during establishement ? Ah yep, there is no need for preemption on this PRI, plenty Bs are free. -- Kanther-Line: PGP SSH IDEA MD5 GOST RIPE-MD160 3DES RSA FEAL32 RC4 +-o-+--------------------------------------------------------+-o-+ | o | \\\- Brain Inside -/// | o | | o | ^^^^^^^^^^^^^^ | o | | o | Andre' Beck (ABPSoft) beck@ibh-dd.de XLink PoP Dresden | o | +-o-+--------------------------------------------------------+-o-+ ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request@bungi.com To get FAQ'd: <<A HREF="http://www.nealis.net/ascend/faq">http://www.nealis.net/ascend/faq</A>> </PRE> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <!--X-Follow-Ups-End--> <!--X-References--> <!--X-References-End--> <!--X-BotPNI--> <HR> <UL> <LI>Prev by Date: <STRONG><A HREF="msg09418.html">Re: (ASCEND) E1 pricing</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg09416.html">(ASCEND) logins slow -- AGAIN</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg09416.html">(ASCEND) logins slow -- AGAIN</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg09419.html">(ASCEND) Two default routes?</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="mail25.html#09417"><STRONG>Main</STRONG></A></LI> <LI><A HREF="thrd193.html#09417"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> </BODY> </HTML>
