First, You need to know what are the parameters needed to configure. This has to be match between your Site or ISP. Namely, Signaling, framing (CRC-4 or NO CRC-4)and linecoding. For E1 the default linecoding is HDB3. The slots in a router, indicates where the WIC are placed. It depends on what kind of router you are using. For 3700 series routers for example, E1 3/0, 3 - means the slot card of your router and 0 - means the port number on which the slot resides.
Second, Is it an E1 R2 or E1 PRI? And what purpose you intend to use E1 connection?

Hey,
Simply put, E-1 configuration could be divided into the following points:-
1. E-1 Controller Config.
2. E-1 PRI Config
OR
2. E-1 Data Config
And all of them could be found well described in the following link.
Please feel free to revert back in case you want anything in more detail.

Hi Samuel,
I have 1 2Mbps leased line terminating to Serial interface of Cisco 2811 router. Now, I have got a ISDN E1 link for backup, for which I want is to configure the E1 controller in such a way that whenever serial link goes down, this ISDN line should come up.
Thanks in Advance,
Suresh

Hi ,
Configure the E1 as follows.
isdn switch-type in global config mode and
Controller E1 1/0
framing esf
line code b8zs
pri-group timeslots 1-32
interface serial number:23
ip address ip-address
encapsulation ppp
dialer map protocol next-hop-address name hostname speed 56|64 dial-string[:isdn-subaddress]
dialer-group group-number
PPP chap hostname
ppp authentication chap
ppp chap passoword.
You need to configure follwoing in global config mode.
dialer-list 1 protocol ip permit
username remoterouter password password.
after configuring E1 and serial line , go to serial interface of leased line and configure the following.
backup delay 5 120
backup interface serialinterface ( configured for isdn)
you need to configure same things on remote end also.You can use dialer interfaces for connecting multiple remote sites.
Hope it helps you.
thanks,
