[Asterisk-Users] Number of TDM405 Cards in one server

[William Boehlke]

Yes, you can use IAX between boxes to handle a shared dial plan. 

There are no single answers. System requirements vary depending on whether
the same box is doing translation, authentication, conferencing, voicemail,
IVR, CDR, call recording, all of them, or none. Generally, we think hot
swappable disks and ECC RAM are more important than a couple GHz.

I will not be using all of the T1s for voice.  I will be using a
combination of voice and data and I don't expect that all of the lines
will ever be full.

Since the people how answered only recommend 1 TE4**P card (thanks
Steven) in a box I imagine that the solution is to setup peering between
separate asterisk boxes in order to create a single overall
"application".

So if I did do two cards any recommendations on whether I should use the
3.3v or 5.0v cards?  Or on  motherboard/memory/cpu specs? 
Obviously I would make sure that there are plenty of IRQs on the
motherboard to handle the cards.

First, START NEW MESSAGES. don't respond to something totally different
and then remove the contents. You message has NOTHING to do with the
message your mail client said you responded to.

Do you want a TDM400 series card or a TE400 series card. Quick mention
of Digium part numbers, TDM/S/X are analog cards, T/E/TE are T1 or E1 or
T1 and E1 capable cards. the first number is a port capacity. 

>From Digiums site, you get this....
The Wildcard TDM400P is a half-length PCI 2.2 compliant card that
supports from one to four telephone interfaces for connecting analog
telephones or analog lines to a PC. ............................... The
naming convention for the TDM bundles is as follows: TDM X Y B. Where
"TDM" denotes that the card is TDM, "X" denotes the number of FXS
modules, "Y" denotes the number of FXO modules, and "B" indicates that
that this product is a bundle.

So you see there isn't a TDM405P or TDM410P. There are however TE405P
and TE410P cards. When you get to T1 or E1 configurations, you shouldn't
look at more than 2 cards per server, and 2 cards should probably be
only undertaken with extreme care and caution. Having a simple hardware
failure take down 96 lines is bad, but not as bad as taking down 192 or
288. If you are routing 288 calls, your downtime cost to repair a single
box will quickly exceed the cost of redundant servers.
