Hello Suryakant,
>> How to configure E1 controller
for what ?
a) DATA
b) voice
a) DATA
unframed: all timeslots used a single stream
controller E1 6/1/7
channel-group 0 unframed
!
this creates a L3 serial interface named ser6/1/7:0 that you can configure as a normal sync serial:
interface Serial6/1/7:0
bandwidth 2048
ip address 10.25.25.2 255.255.255.252
no ip directed-broadcast
ip router isis f1
encapsulation ppp
load-interval 30
keepalive 1
no cdp enable
!
within data you can also:
have a single channel-group using all the slots
controller e1 0/0
channel-group 0 timeslots 1-31
or fractional
controller e1 0/0
channel-group 1 timeslots 1-15
channel-group 2 timeslots 16-31
the second creates two serial intefaces
ser0/0:1
ser0/0:2
Hope to help
