IPO403 - BRI Backup when WAN down

IPO403 - BRI Backup when WAN down

IPO403 - BRI Backup when WAN down

Dear Users and Admins and Others
Hardware = IPO403 - ver. 1.3(32)
WAN = HDSL 2048bit (protocol V.35)
Inside configuration I've added correctly WAN all options and WAN works correctly (!). I've added BRI numbers in field TelephoneNumber in Service (Intranet Service SiteB) at SiteA and my problem is that I've to wait very long time for connection via BRI (when power on HDSL is off)and very offten SiteX cannot make connection via BRI to SiteY.

Are any ShortCodes for estabilish connection from X->Y or from Y->X manually from any phone (BRI at SiteX is 1000 at SiteY is 2000)?

Or maybe I should dosomething different to estabilish connection automatically when DATA or VoIP is comming?

Dear IPO Admins.
When you connect IPO BRI to PBX end-user line - IPO is looking for channels in BRI started on CH1 and after non-signal started in CH2. So CH1....CH2....Ch1....Ch2

To correct connection in BRI BCKP you must dial manually "bad channel" andstay ready on good Channel in both lines (both IPO).

When you connect BRI directly from PSTN or NT everything is working correctly.


RE: IPO403 - BRI Backup when WAN down

Correct me if I have the wrong idea, I'm assuming you are passing voice traffic;

Why not make the ISDN on line group 0 which is default, and you HDSL on line group say 20.

In site A;
 For ISDN use "9N,0207299N,0,dial" (where N is the extn number of site B, and 0207299 is the first half of ISDN number at site B)
 For HDSL use "N,.,20,dial"

etc etc

Best speak to your provider. How often do you use your ISDN 2 circuits? I know for a fact if you use BT (I'm from UK) and your ISDN2 is not used for a month, BT will make the circuit go down. Hence, it's useless as backup line, unless you make the odd call on the ISDN2.

About your post.
You are right! Everything was OK when I've connected to NT (directly to BRI). In my office I've used end-user line from PBX, because we have only that card. All your tips are Ok. It works OK on voice-end-user BRI.
