Currently onsite trying to get this T1 up and running.
Just talked to the T1 guys and they said their end was up and they saw that I plugged in my 2801 router (via WIC T1 card).
Attached is the running-config on the router. Is there anything obvious I'm missing? The Ethernet int is going to the local ASA which I haven't brought up yet. I just want to get the T1 communicating. I'm trying to ping the Serial gateway (1.2.3.185) but nothing.
Help?
(sorry so brief, in a rush)
Solved! Go to Solution.

I'm not asking if it requires PPP authentication, just PPP encapsulation. Right now you have HDLC. Verify that HDLC is OK with your carrier (usually it is not).

Just removed the ACL's from the Serial0/1/0 interface, still no luck.
Yet the T1 techs say they have Layer1/2 on their end... say it should work.

Hi,
IMHO,
access-list 101 deny ip 7.8.9.224 0.0.0.8 any
might be blocking the Ping replies.
Do you see anything in the "sh arp" output?

Hello,
I removed the ACL all together and still no luck. :-(
"sh arp" just returned the local ASA off the ethernet interface.... nothing off serial

Does the carrier require an encapsulation type (ie PPP)? What is your interface status? Can you check your DSU settings (framing, linecode, etc).

I am so not a Layer3 person. Thanks for any help!
I'm still reading through that page you linked
Still can't get out.

From Cisco, an example of configuration-
interface serial 0/0/0
service-module t1 clock source line
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
ip address 10.1.1.1 255.255.255.252
encapsulation ppp
fair-que
no shut
Default commands will not show up in the config.

Collin,
That was it!
I went ahead and changed the encap to PPP and was instantly able to ping out.
I hooked up the ASA and tried pinging out, but nothing. So I went in and removed the ACL's again and boom, I'm able to get out.
So the encapsulation was it! Thank you so much! I'm sorry I misunderstood your initial question. Thank you again and again!
Now to work on my ACL ;-)
ratings given.

Glad to hear it's up. Post if you need help on the ACLs.
