Digium Wildcard X100P questions


#1

I’m completely new to Asterix, and I’m trying to get some cheap hardware that will help me learn the system.

I’ve seen X100P cards on eBay at very reasonable prices. And I know I can take a phone line from the outside world and run it into an Asterix PBX with one of those cards.

But is it possible to use one of those cards to connect a cheap analog phone to the PBX? Can I take a phone cord and run it from the X100P into a phone, and configure asterix so the phone is usable?

Or do I need to go with a SIP phone (soft or hard)?

X100p is an FXO used to connect to the PSTN for an analog phone you would need an FXS device.

There are several way you could do it check these links

Thanks very much for the reply.

I I think I read in a FAQ somewhere that to Asterisk, there’s no difference between a FXO and a FXS, they both appear as channels. I might have that wrong, though (I’m having trouble finding it), and I might be misinterpreting it.

From your response, I guess my confused newbie take on this is that from a configuration point of view inside of asterisk they look the same, but physically, you have to plug one sort of thing into one, and the other sort of thing into the other?

Thanks again…

yes asterisk sees both as a zap channel but the signalling it uses is different

FXO (Foreign eXchange Office) is the office end of the line, and FXS (Foreign eXchange Station) is the station end.

FXO and FXS are also used to refer to the type of interface on phone equipment.

An FXS interface provides power (battery) and generates ring signals.
An FXO interface receives power (battery) and receives ring signals.

Unfortunately not. The X100P clones off ebay (or other source) do not generate a dialtone. There is an in-line socket to connect a fax or an analog phone, but this is parallel to your POTS line. Whatever you plug in, it is not available to asterisk, e.g. to set it up with an extension.

Could I get some clarification on RedStapler’s response?

The X100P will only allow POTS input, correct? Does it work something like this?

POTS --> [ X100P in RedHat box to NIC] --> to VoIP Soft Phone

In other words, you can’t plug a POTS line AND a analog phone into the X100P. Correct?

[quote=“kolberda”]Could I get some clarification on RedStapler’s response? [/quote] Let me try

[quote]The X100P will only allow POTS input, correct? Does it work something like this?
POTS --> [ X100P in RedHat box to NIC] --> to VoIP Soft Phone[/quote] Correct, the VoIP soft phone can be called by extension, based on the Asterisk dialplan

[quote]In other words, you can’t plug a POTS line AND a analog phone into the X100P. Correct?[/quote] This is correct as well. One comment: The X100P has two analog jacks. One for line in, the other is a line out. You can connect an analog device, however when you call from the outside, both Asterisk and the analog device will “ring”. Which device ever picks up first, takes the call. This line out is not “in” Asterisk, it just daisy-chains your analog device and Asterisk, similar to what an external modem does. This analog device is outside Asterisk, is not visible and you cannot “do” anything with it.
I hope this helps. If (just in case) you need to connect an analog device “in” Asterisk, you need an ATA (analog telephone adapter) or a real Digium card with an FXO and and FXS module.
