Hi Guys,
Trying to fill up a form for an order of a PRI circuit. Will be using either of Sangoma A101D or A102D with Asterisk 1.4 or 1.6. Not sure about some of the terms and wondering what is supported by the mentioned Sangoma cards and what are the disadvantages/advantages of using one option over the other: (I have filled out some fields hoping it's right for my needs) # of DS1 Accesses = ? ; Not sure what to put? 24? # of B Channels = 23 ; I guess this is standard for 1 circuit # of D Channels = 1 ; No need to have more than 1 of this either Back up D required = y/n ; what is the advantage of having a backup D? Line Coding & Framing = B8ZS / ESF ; Which one to pick and why? Trunk Selection Sequence = Asequential/ASEQ(ascending)/DSEQ(descending)/MIDL(most idle)/LIDL(least idle)/CW(clockwise)/CCW(counter clockwise) Using one DID and hunt all other numbers. Which to pick? I guess (ascending) Type of interface required at demarc = RJ45/DB15 ; what is going to be for Sangoma A101D card? Digits to Outpulse = 0-10 digit ; what is this? ISDN Protocol = NI-1 or NI-2 ; which one to pick and why? Overflow Required = y/n Include D channel failure ; how necessary is this specially with D Channel. Hunt Grou = y/n ; obviously YES Virtual Group = y/n ; what is this? Digit Substitution Required = y/n ; what is this? Thanks for answering any or all of the above. -Bruce _________________________________________________________________ Say Happy New Year with Messenger for Mobile. http://go.microsoft.com/?linkid=9706117
