Once You are done with Loop back connector.
Use the following configuration.

[channels]
callerid=asreceived
resetinterval=never
pridialplan=unknown
signalling=pri_cpe
switchtype=euroisdn
immediate=yes
group=0
context=test_in
channel=1-15,17-31

group=1
signalling=pri_net
context=test_out
channel=32-46,48-62


And in extensions.conf

[test_in]
exten => s,1,Answer();
exten => s,n,Playback(tt-monkeys)
exten => s,n,hangup();

[test_out]
exten => _X.,1,dial(DAHDI/g1/${EXTEN},60,R)

Once  You are done with configuration you can test by making a call using
asterisk cmd dial application in console.
