[asterisk-users] Tips for installing and configuring Digum cards
Tomorrow evening I'll be at a customer site installing 2 Digum cards - a 4 port analog and 2 port T1. I'd appreciate any tips, resources and links that you have that might help if we run into trouble. It will, of course, be fairly late at night and relatively high pressure to get it working, so I'd like to collect as much information in advance as I can. I was able to install and test the analog card in my lab, so not too worried about that. I installed the T1 card in the lab and got the system and Asterisk to recognize it, but had no T1 to test with. -- Mitch

Sometimes Telco's technicians tend to sound very secure of information they have not confirmed. -- # Pavel E. # http://www.slackware-es.com # Skype: p.espinal # IRC: Khratos @ #asterisk / -doc / -bugs

[asterisk-users] Tips for installing and configuring Digum cards
In case the moderator doesn't approve my post with the attachment, below is a quick and dirty transcription of the order form. Customer connecting equipment: CSU/DSU Circuit: DS1 Line coding: B8ZS Framing: ESF Jack type: RJ48X / Smartjack (will that fit into the Digum card?) ISDN protocol: NI2 Primary D-channel assignment: 24 FAS Incoming port selection: Ascending sequential 1-24 Indound real-time ANI delivery? yes, 10 digits Does anyone see any red flags or things to watch out for in these specs? Anyone configured a similar line that is willing to share your config files? I'm traveling for the next several hours, so apologies if I don't respond right away.
