[asterisk-users] Need to buy the Digium card, to confirm

[bilal ghayyad]

Hi All;

My server and its slots written in it the following so I need to know which card to order it (I need a card supporting 2 E1s):

PCIE_G2_X4
PCIE_G2_X8

Actually I do not know what is meaning by G2.

OK I tried to buy directly from the below link but I found it is mentioned that it is x1 and not x4 or x8 so how can I get x4 or x8?

The link:

http://store.digium.com/productview.php?product_code=TE220B

Description for the product:
Two (2) span digital T1/E1/J1/PRI PCI-Express x1 card 

So please advise what do to?
Regards
Bilal
