If you are using the IPv8 architecture, then your Asterisk-based GK (GateKeeper) is a LAN to WAN device.

You can connect analog phones to the LAN in a variety of ways.
The PhoneJack (http://www.quicknet.net) is one common interface to use.
Each vPC uses one and it can ring the analog phone.
http://www.linuxjack.com/ is a link to the same products. ($110)
You can also use more expensive LAN phones, which may not be what you have referred to as "analog phones".

The single analog line interface to the central office is handled by the FXO (Foreign Exchange Office) interface.
http://www.Digium.com ($99)

The total picture for one-line is...
vPC+PhoneJack--------LAN-------Asterisk(GK)+FXO-------DSL------{InterNAT}-----PK

If you only have this configuration, then you can dial into Asterisk via the FXO hardware.
Asterisk(GK)+FXO-------DSL------{InterNAT}-----PK
That is another way to "attach analog phones", but is not likely what you need for a local site.
