Hello,
i have Cisco RAS5300, and i never have worked on controller E1 befor,
i will connect the E1 ports to a PSTN so that people can dialin and connect to the RAS.
what do i need to configure? and what is the use of the seial interfaces and if i will need them?
below is my sh run:

when you configure a 'controller' properly for use, it will create serial interface(s) on the router that you will then need to configure to complete the connectivity via E1.
(it's actually easier than it sounds)
the E1 can be configured for common channel signaling (CCS) or channel associated signaling (CAS).
please see the following links for info on configuring an E1 controller:
PRI E1 (CCS):
channelized E1 (CAS):

Hello & thanks for your reply,
i looked at the documet which was very helpfull, the channalized one.
i would like to ask:
which type of E1 do i need? PRI or channalized?
my typical use is to connect the RAS to our PSTN, and people can dial in , we will have 8x30 dialin ports (240).
also, i can configure the E1 as the documents provided information, but what about Serail interface? why do i have to configure it? and do i have to connect the physical serial interface somewhere? i have 4 serials in my RAS.
Thanks for any info,

May be you are getting confused betwween controller and serial interfaces :
1st case:If configured as a unframed serail interface numbering is same as for controller only need to add group number.
controller E1 3/0
channel-group 0 unframed
!
interface Serial3/0:0
description ** UNUSED **
no ip address
ip load-sharing per-packet
shutdown
no cdp enable
2nd case:here you can alocate bandwidth for channels.serial port numbing is same as for controller add corresponding channel group.
controller E1 5/0
channel-group 0 timeslots 1-4
channel-group 1 timeslots 5-6
channel-group 2 timeslots 7-8
channel-group 4 timeslots 11-12
channel-group 5 timeslots 13
channel-group 6 timeslots 14-15
channel-group 7 timeslots 16-17
channel-group 8 timeslots 18-19
channel-group 9 timeslots 20-21
!
interface Serial5/0:0
description ***** UNUSED******
ip address 203.195.147.254 255.255.255.252
encapsulation ppp
no cdp enable
3rd case:IF configuring PRI
controller E1 4/0
pri-group timeslots 1-31
description <
chennel 15 is being used for singalling .
interface Serial4/0:15
description ### PRI Number###
no ip address
encapsulation ppp
dialer pool-member 1
dialer pool-member 2
dialer pool-member 3
now create a dialer with ip config.
interface Dialer1
description "UNSED"

Hello sir,
thanks for the configuration.
after i do:
controller E1 0
channel-group 0 timeslots 1-30
!
interface Serial0.15
..
..
..
!
my RAS is connected to the internet through FastEthernet0.
but i still dont know why do i have to configure a logical serial interface and a Dialer?
cant i configure the channalized E1 lines 1-240 for ppp , modem inout , etc.. ?
thanks

see whatever you are configuring PRI/channelized E1 30 channels are there incase suppose u have 30 Links of 64 Kbps you have to configure 30 serial links like s1/0:0----s1/0:30 or may be dialer1-255 but at a time 30 in/out call will be in use.Chjennalized e1 we use for Lease Line and PRI for dial-up Hope you got the answer for your question.
