HI All,
I have configured 3845 router remote and main location with Analog back line. I am getting only 34kbps speed with analog connection.
Anybody can help me how I can make it 56kbps.
Following are Dialin side configration.

You would need to use a digital modem module, and terminate the calls on either a BRI or PRI interface to achieve 56kb speeds. Analog modems to analog modem calls cannot achieve 56kb. One side of the call has to be digital.

56 Kbps (V.90) can be achieved when the peer is a digital modem (for example, a AS5xxx with a digital circuit such as a T1 or E1 line)
56 Kbps (V.90) cannot be achieved when connecting to an analog modem. This is a limitation of V.90 technology and is not a hardware issue. Refer to Overview of General Modem and NAS Line Quality for further information.
