If I am interpreting the question right, the two major physical types of interface with a router are wired or wireless. You either interface over a cable, or by a wireless radio signal

Routers will generally have at least a couple of plain old 10/100 Ethernet ports. Many will have modems built in, such as an ADSL modem, which you'd plug a phone line into, or a cable modem, which you'd plug a coaxial cable into.
Routers sold to businesses are often designed with swappable card slots. So, if a business gets a T1 line, they can get a card with hardware for a T1. Later, if they switch to DSL, they switch it for a DSL card.
Each manufacturer of routers has their own cards, and their own name for them. Cisco Systems usually calls their cards WAN Interface Cards (WIC for short) and most of their routers have several WIC slots. 3Com calls them Flexible Interface Cards, and the concept is the same.
You'll generally be able to buy cards for T1s, E1s, DSL, T3s, E3s, plain old copper, and often, a company will make cards with other things (such as SFP slots http://en.wikipedia.org/wiki/SFP_transceiver).

Depends on the type/size of router, and what OS it's running.
