Cisco 887va VDSL connectivity problem!

[cameran93m]

Dear Friends, Hello First of all, sorry for my weak English! I've got a Cisco 887va-K9 and I want to connect it to my ISP (A1-Austria) with the credential they gave me. (I am sure that my username and password are correct. I already connected to internet with these username and password by another VDSL modem that my ISP provided.) The problem is: The CD-LED (Carrier Detect) comes shortly green and quickly (after 10-15 Sec.) start blinking again. When it is green, the "Show ip interface brief" result is: R887VA(config-if)#do show ip inter br Interface IP-Address OK? Method Status Protocol ATM0 unassigned YES NVRAM administratively down down Dialer1 unassigned YES NVRAM up up Ethernet0 unassigned YES NVRAM up up Ethernet0.2 unassigned YES unset up up FastEthernet0 unassigned YES unset up down FastEthernet1 unassigned YES unset up down FastEthernet2 unassigned YES unset up down FastEthernet3 unassigned YES unset up up NVI0 unassigned YES unset administratively down down Virtual-Access1 unassigned YES unset up up Vlan1 192.168.1.138 YES NVRAM up up And same time the “Show controller vdsl 0” result is: R887VA#show controller vdsl 0 Controller VDSL 0 is UP Daemon Status: Up XTU-R (DS) XTU-C (US) Chip Vendor ID: 'BDCM' 'BDCM' Chip Vendor Specific: 0x0000 0xB1A9 Chip Vendor Country: 0xB500 0xB500 Modem Vendor ID: 'CSCO' ' ' Modem Vendor Specific: 0x4602 0x0000 Modem Vendor Country: 0xB500 0x0000 Serial Number Near: FCZ1907C0WD C887VA-K 15.3(3)M4 Serial Number Far: eq_nr multiline_cpe software_rev Modem Version Near: 15.3(3)M4 Modem Version Far: 0xb1a9 Modem Status: TC Sync (Showtime!)
