Need to replace 4-port Tiger3XX FXO card


I have a 4-port Atcom card and upgrading the system that it’s currently in. The new system has only a PCI-E slots with the following specs:

2 PCI-E 3.0 x8, 1 PCI-E 3.0 x4 (in x8),
1 PCI-E 3.0 x16, 1 PCI-E 2.0 x2 (in x8),
1 PCI-E 2.0 x4 (in x8)

Can you recommend a replacement card that will work in my system? This is for the Supermicro X10SRi-F motherboard (

I’ll have just one incoming line supporting a few IP450 phones.

It looks like the Atcom AXE400P would be an appropriate replacement? Other suggestions?

I don’t think I understand the difference between FXO and FXS. It appears there are some cards with FXS support without FXO support, and vice-versa. I believe it is FXO that I’ll need, from what I recall.

Here are the specs from the existing card:

03:05.0 Communication controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface
Subsystem: ATCOM Technology co., LTD. AX400P 4-port analog card
Flags: bus master, medium devsel, latency 64, IRQ 20
I/O ports at e800 [size=256]
Memory at febff000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [40] Power Management version 2
Kernel driver in use: wctdm
Kernel modules: hisax, wctdm, netjet


Try a Digium card. :smiley:

Buying from Digium supports the ongoing development of Asterisk and the DAHDI drivers for the cards. Buying from Atcom doesn’t.

The 4-port PCI-E card offering is the A4B model [1]. It’s got a PCI-E x1 connector, so it’ll fit into any PCI-E slot.

For a line from the telco, you’ll need an FXO interface on the card.

If you were pushing your own line to an analog telephone, you’d need an FXS interface on the card.

Here’s [2] our horribly dated page on FXO and FXS.
