Re: [OSL | CCIE_Voice] ISDN bchan selection
You can configure the router to select the first available B channel in ascending order (channel B1) or descending order (channel B23 ). By default, the router will select outgoing calls in descending order. 2011/6/1 Randall Crumm rrcr...@yahoo.com Just to make sure top down mean channel 23 to 1 do I would configure isdn bchan descending Thanks, randall ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?

Re: [OSL | CCIE_Voice] ISDN bchan selection
Top Down = Assigned starting at channel 1 and working through the high end (23 on a T1 PRI) Bottom Up = Assigned starting at channel 23 (T1 PRI) and working through to the low end If the PSTN is using Top Down (validated by running debug isdn q931 and noting the channel assigned when calling in from the PSTN to CUCM), you would want to use isdn bchan descending (sets your end to Bottom Up). If the PSTN is using Bottom Up (same validation process), you would want to use isdn bchan ascending (sets your end to Top Down) Date: Wed, 1 Jun 2011 10:01:12 -0700 From: rrcr...@yahoo.com To: ccie_voice@onlinestudylist.com Subject: [OSL | CCIE_Voice] ISDN bchan selection Just to make sure top down mean channel 23 to 1do I would configure isdn bchan descending Thanks,randall ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?

Re: [OSL | CCIE_Voice] ISDN bchan selection
It helps me to visualize a ladder, with the rungs being the channels, and rung (channel) number 1 being at the top. Ascending and descending refer to *numerically* ascending or descending - so ascending numerically (from channel 1 to channel N) means going top down on the ladder. Likewise, descending numerically (the default; from channel N down to channel 1) means going bottom up on the ladder. So Randall, your statement is incorrect. Top down = descending = channel 1 to 23. Just my little mnemonic. YMMV :) cheers, sd From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of Cristobal Priego Sent: Wednesday, June 01, 2011 1:38 PM To: Randall Crumm Cc: Online Study Subject: Re: [OSL | CCIE_Voice] ISDN bchan selection You can configure the router to select the first available B channel in ascending order (channel B1) or descending order (channel B23 ).

Re: [OSL | CCIE_Voice] ISDN bchan selection
ascending is 1-23, just did this at a customer so I know that is right and confirmed with show isdn q931 descending is 23-1 as is the default.

Re: [OSL | CCIE_Voice] ISDN bchan selection
Whoops. I was doing fine up until that last cut and paste error. :) Bill's absolutely correct; that last line should have read Top down = *ascending* = channel 1 to 23. cheers, sd From: Bill Lake [mailto:whl...@gmail.com] Sent: Wednesday, June 01, 2011 4:34 PM To: Steve Denney (stdenney) Cc: Cristobal Priego; Randall Crumm; Online Study Subject: Re: [OSL | CCIE_Voice] ISDN bchan selection ascending is 1-23, just did this at a customer so I know that is right and confirmed with show isdn q931 descending is 23-1 as is the default.
