Cisco SPA 100 ATA

[#1]

Daft question for some and yes, I have read the instructions but do I connect the ATA to the wifi router, or the hub/box that's fixed to the wall. Seems I should use the blue cable supplied but the router only has yellow connections and the hub/box black ones....and why does it have two telephone points? I'm guessing it's for a VoIP telephone.

You'd want to connect the cable to the router, the colour of the sockets / wires have nothing to do with it, only aesthetics. The two connections are for POTS or plain ordinary telephones, as VoIP phones usually use a LAN cable.

@Minivanman BTW have you got the SPA112 or the SPA122 ?

OK thanks, will give it a go cheers.

As regards to those two telephone connections, how would an ordinary (ADSL) telephone work plugged directly into a fibre line?

@MisterW

SPA112 - the one with two telephone sockets.

@Minivanman Bear in mind that the 'SPA xxx ATA' devices have routing capabilities so that might be an additional thing to bear in mind.  At a guess that will probably need to be disabled.

The "hub/box that's fixed to the wall" would be better referred to as the ONT. 

[#7]

As backup and to allow you to use the system when no VoIP phones are available.

@RobPN

ONT, thanks 

How would I disable the routing capabilities?

@Minivanman both the 112 and the 122 have two telephone sockets!

The 112 has one Ethernet(WAN) connection(BLUE) wheras the 122 has two Ethernet connections, one LAN(yellow) and one WAN(Blue).

It matters as @RobPN says because the 122 has routing cabability and this will need disabling in the setup

I don't get that sorry.

Surely if an ordinary phone worked when plugged into the ONT then there would be no need for an ATA?

That just seems a logical step to me, but I don't have any experience of those units

Forget backup, some ATA's have the ability to connect to a normal PSTN line as well as telephones. The SPA doesn't and you don't actually have a PSTN line anymore anyway!

IF you have an SPA122 then you will need to set the network service to 'Bridge mode' ( page 25 of the manual ) and ensure you connect the router to the BLUE(Internet) port on the ATA. If you have a 112 then you don't need to.

Short answer, it wouldn't, and how would you plug it in anyway?

"Short answer, it wouldn't, and how would you plug it in anyway?"

Because it has two BT telephone female sockets underneath the ONT Rob.

Just looked at the specs of your box and what you have there are two FXS ports to which you can connect POTS to. This site explains what it's all about.
