I'm trying to setup a test environment with 2 2650XM routers that have 1 NM-1T3/E3 card each. I have a 9ft coax cable connecting the 2 routers together. Is this setup possible to configure? My configs are below and the AL & EN LED are lit. How can I get these two routers to talk?
This is my config so far:
Router1#:
!
version 12.3
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
!
hostname Router1
!
boot-start-marker
boot-end-marker
!
card type t3 1
!
no aaa new-model
!
resource policy
no network-clock-participate slot 1
no network-clock-participate wic 0
ip subnet-zero
ip cef
no ip dhcp use vrf connected
no ip ips deny-action ips-interface
no ftp-server write-enable
controller T3 1/0
cablelength 9
no crypto isakmp ccm
interface FastEthernet0/0
ip address 192.168.1.6 255.255.255.248
duplex auto
speed auto
interface Serial1/0
ip address 192.168.1.17 255.255.255.252
dsu bandwidth 15000
ip classless
ip http server
no ip http secure-server
control-plane
line con 0
line aux 0
line vty 0 4
end
Router2#:

end
TIA!

For the connection to work there must be someone supplying clocking. For back to back connections you should configure one of the controllers with clock source internal.

I have them both set to internal right now. I will set one to line and see what happens. Thanks.

I have one set to line and one set as internal and it's still a no go.

In looking at some T3s that I configured I have a couple of parameters that you do not. It might be worth trying these to see if they make a difference:
keepalive 8
scramble
serial restart-delay 0

Thanks for your time Rick, but I just posted my problem and resolution.

I am glad that you got it figured out. Thank you for posting back to the thread and explaining what the problem turned out to be. It makes the forum more useful when people can read about a problem and can read what the problem was and how it was solved.

Nevermind, I had my cables plugged in incorrectly. I had my cable #1 going from TX on one rotuer to TX on the other router, and the same with cable #2 with the RX. I flipped the TX & RX cable on one router around and it started to work, both configured to clock source line. So now my cables are: cable #1 in TX on Router1 and cable #1 in RX on Router2 and same with cable #2.

Hello Mike,
this can happen every day don't worry, and it was kind of you to report the solution it can be helpful.
