T1 cards

I'm about to grab some T1 cards on ebay and I see both VWIC-2MFT-TI and VWIC-2MFT-T1-Di cards. I know not to get the DIR cards, but

1. Between the VWIC-2MFT-TI and VWIC-2MFT-T1-Di cards does it matter which one I buy for my voice lab? The Di versions are cheaper than the non-di versions.

2. Will I be able to mix and match the di and non-di cards if I'm just doing it for basic CCVP lab prep.

you will be fine with both of them.. i currently run the DI version and have no problems.

Thanks man, it's insane how expensive my lab is getting, and I didn't even bother with FXS/FXO ports.

Just stay clear of the "DIR" versions as they only work in some really old wireless edge routers.

Adds up quick doesn't it!

Lab looks great! Be sure to post some pics in the top "revamped" lab thread once you get it all cabled up! Man, you guys are killing me with your shinny 3750s! Voice labs are expensive but worth every penny if you're committed to putting in the time.

You'll find that the 6 button phones come in handy – I started with all 7941s and had to change things around every time that I wanted to play with a line or feature. With the 6 buttons, you can have a bunch more items setup at once.
