Hello,

I have never configured a Cisco router before.  After going through the basics of setting up a password, encrypting it, and learning about the different interface commands I have decided to start configuring the WIC-1DSU-T1 to work with our new T1 line.

I configured serial 0/0 with the following (ip addresses hidden for this post):
  (config)
  interface serial 0/0
  ip address x.x.x.x s.s.s.s
  service-module t1 clock source line
  service-module timeslots 1-24 speed 64
  service-module framing esf
  service-module linecode b8zs
  encapsulation ppp
  fair-que
  no
  no shut

show interface serial 0/0
Serial0/0 is up, line protocol is up
  Hardware is PQUICC with Fractional T1 CSU/DSU
  Internet address is x.x.x.x/28
  MTU 1500 bytes, BW 1536 Kbit, DLY 20000 usec,
     reliability 255/255, txload 3/255, rxload 4/255
  Encapsulation PPP, LCP Open
  Listen: CDPCP
  Open: IPCP, loopback not set
  Last input 00:00:07, output 00:00:06, output hang never
  Last clearing of "show interface" counters 00:54:44
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
  Queueing strategy: weighted fair
  Output queue: 0/1000/64/0 (size/max total/threshold/drops)
     Conversations  0/1/256 (active/max active/max total)
     Reserved Conversations 0/0 (allocated/max allocated)
     Available Bandwidth 1152 kilobits/sec
  5 minute input rate 25000 bits/sec, 4 packets/sec
  5 minute output rate 24000 bits/sec, 4 packets/sec
     12668 packets input, 1518409 bytes, 0 no buffer
     Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     12152 packets output, 1451671 bytes, 0 underruns
     0 output errors, 0 collisions, 1 interface resets
     0 output buffer failures, 0 output buffers swapped out
     0 carrier transitions
     DCD=up  DSR=up  DTR=up  RTS=up  CTS=up

I thought that I did all I needed to do in order to get connectivity to the internet, but I cannot even ping our assigned gateway address.

That's it, I haven't tried anything else because i don't know what else I need to do at this piont.  Your input is appreciated.  Thanks!
Regards,
Carlos

Looks like everything is up and functioning.
Packets coming in and going out is a good sign.
> 12668 packets input
> 12152 packets output

Can you post your config?

Here's another idea...  I stranded a regular CAT5 Ethernet cable from the WIC card to the MPOE, but I'm reading about a different wiring scheme for T1.  Do I need to strand the cable differently?

Thanks!

No. Standard CAT5 patch cable is right. If it wasn't, you would see fast increasing CRC errors, and most likely not get a "up" condition.

Irmoore,  what other information would help you help me diagnose the problem?  You asked for a config - what command would I run to gather this information?  (I'm new to IOS)

If your gateway is supposed to be 216.31.251.129:
add this:
  router#config t
  router(config)#ip route 0.0.0.0 0.0.0.0 216.31.251.129

alternative:
    router(config)#ip route 0.0.0.0 0.0.0.0 serial0/0

I tried that and I still can't seem to ping the gateway from the router console.

We are making some progress now.  It appears that the gateway is simply not responding to ping requests.  I am able to traceroute all the way to the PDNS now.

Looks like we solved problem #1.  I'm sure I will have more as I continue to learn to drive this thing.
Thanks for your help!!

Carlos
