Physical Connection for Cisco 1861 router

Hello All Friends's,

I am unable to understand how to plug Internet cable into 1861,  it's strange I never see any VOIP router, But I am always trying to configure, I am doing try to configure from remote location & my partner said the 1861 has a WAN port at the back it doesn't have a built in ADSL modem as a lot of enterprises use connections other than ADSL,so we need the modem to provide the internet connection to the 1861, in Perth there is a router there which was configured for a straight through connection when the UC520 was installed so the router's wifi, dhcp etc is all inactive
it just acts as a modem I figured I would just get a modem and plug it into the 1861,

I can't suggest him for making connection,  can anyone point me for making connection, it will be a great if you can provide me any snap

it's so difficult i think but i hope experts will solve my issue
Please point me in right direction

Regards

VIkrant

If I understand your question you are looking for a way to connect your 1861 to the Internet.  If you have an ADSL modem, you connect it to your Fast Ethernet port.  There are also ADSL HWIC modules available for the 1861.

Mate, you need to set your ADSL modem(s) to "bridge" or bypass mode.  Connect a straight-through or cross-over from the ADSL model to the router.  Do your Dialer interface configuration on your router.

The 1860 will support MDI/MDI-X.  Give it a go.  That's why I said "or".

Sorry it's my confusion, I had not seen "or" & straight cable, If i use Bridge it will work,

1  more question Bridge & straight-through is same or difference..
