I have a problem with configuration of Cisco 876 router.
I just cannot make him connect to remote site on BRI interface or via Dialer. Either interface reults with 'Encapsulation failed'. I have used standard configurations for this, as attached. Please help me understand this error.

First of all, from the info provided it is not possible to check that a successfull dialing attempt has been made.
Making sure that this is ok would be the first step. The "encapsulation failed" messages are likely due to this fact.
For this, establish a constant ping to a destination that can be reached via the dialer.
Then only use the following debug commands:
deb dialer
deb ppp neg
About your config:
You seem to have used both old and new methods, the old one being to put the dialer config on the corresponding interface.
The recommended solution is to use dialer interfaces.
Make your bri0 a member of dialer-pool 1 and have the dialer using this pool for calls.
Remove most of the config on the bri interface and put it on the dialer instead.
Also, do not attempt to use callback before the rest is working properly. You can then start more comfortably with is from a working situation.

To specify, for a dialer interface, which dialing pool to use to connect to a specific destination subnetwork, use the dialer pool interface configuration command.
You seem to be missing the interface-command:
" dialer pool 1 "
under your dialer 1 configuration
Please add this command and retry. ;-)

When trying to input 'dialer pool 1' as above, we get
'Highways(config-if)#dialer pool 1
%Remove Legacy DDR Configuration first'
which means removing the 'dialer map' statement.
Please advise.
