It is *not* that the digital phones do not need a card. It is that there
is no card on the market that will work with them.

It will not use ethernet switches.

No, it does not, and it will probably never work.

To make it even clearer:

Bilal -- You cannot use your digital phones with Asterisk. Period.

Either:

1 - use a matching digital switch (Nortel Meridian or Norstar, etc.)

2 - sell the phones and replace them with proper IP phones that you can
use over an IP network.

If you are concerned about availability in the event of a power failure:

Purchase an Uninterruptible Power Supply of the appropriate size, Power
over Ethernet injectors, and configure your system such that it will
stay up during a power outage.
