Serial interfaces Link Status Down.

Dear All,

 

I've installed E1 card (VWIC3-4MFT-T1/E1) in cisco 2911 router (IOS version 15.4) and configured accordingly. But  Link Status of serial interfaces 

down. Here is the  Card configuration and Sh interface serial 0/0/0:0 commands result-

 

Card Configuration:

Step:1
=====================================
card type e1 0 0
card type e1 0 1

Fast Card Interface Configuration
===================================
controller E1 0/0/0
 framing NO-CRC4 
 channel-group 0 timeslots 1-31
!
controller E1 0/0/1
 framing NO-CRC4 
 channel-group 0 timeslots 1-31
!
controller E1 0/0/2
 framing NO-CRC4 
 channel-group 0 timeslots 1-31
!
controller E1 0/0/3
 framing NO-CRC4 
 channel-group 0 timeslots 1-31


Second Card interface configuration
============================================
controller E1 0/1/0
 framing NO-CRC4 
 channel-group 0 timeslots 1-31
!
controller E1 0/1/1
 framing NO-CRC4 
 channel-group 0 timeslots 1-31
!
controller E1 0/1/2
 framing NO-CRC4 
 channel-group 0 timeslots 1-31
!
controller E1 0/1/3
 framing NO-CRC4 
 channel-group 0 timeslots 1-31

 

And here is the serial interface status:

sh interfaces serial 0/0/0:0
Serial0/0/0:0 is down, line protocol is down 
  Hardware is DSX1
  MTU 1500 bytes, BW 1984 Kbit/sec, DLY 20000 usec, 
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation HDLC, crc 16, loopback not set
  Keepalive set (10 sec)
  Last input never, output never, output hang never
  Last clearing of "show interface" counters never
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
  Queueing strategy: fifo
  Output queue: 0/40 (size/max)
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     0 packets input, 0 bytes, 0 no buffer
     Received 0 broadcasts (0 IP multicasts)
     0 runts, 0 giants, 0 throttles 
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     0 packets output, 0 bytes, 0 underruns
     0 output errors, 0 collisions, 2 interface resets
     0 unknown protocol drops
     0 output buffer failures, 0 output buffers swapped out
     1 carrier transitions

So what is the problem and how can i up the link status?
