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

[Miroslav Nachev]

Hi Marcelo,

We use Linux 2.4 and the result is the same - TDMoE doesn't works and
the network is crashed.

MP> ... T1 channel banks (US$ 500) with 24 FXS ...

From where can I find the above T1 Channel Bank? Some URL?
