[Asterisk-Dev] How to use more PCI Cards with FXO/FXS in case that TDMoE doesn't work

[Marcelo Pacheco]

Miroslav,

It's my experience that TDMoE is unstable with 2.6. On my workstation/router 
it will stop my PPPoE session and cause IP stations to cease responding to 
pings, eventually locking up the machine. Athlon XP 2.6 333 FSB 1GB RAM, ECS 
KT600-A motherboard, 2 SATA drives, tried lots of kernels from 2.6.5 to 2.6.8 
some vanilla, some conectiva snapshot and the official conectiva 10 kernel.

On another machine also with 2.6 it will not lockup, ever, but it will result 
in plenty of TDMoE timeouts causing channel restarts.

It apears to work ok with 2.4 only.

For a configuration like yours, I would use a quad E1/T1 card with one slot in 
E1 mode, one in T1 channel banks (US$ 500) with 24 FXS, and then use 
TDM400P's only for the FXO's, that would use 4 slots (1 quad E1/T1, 3 
TDM400P's with 4 FXO each).

PS: This is not asterisk-dev subject except for the lockup/TDMoE issues.
