Setting up T1 between 2 cisco 1700's, but I am unable to get this working here are the errors i'm pulling thru "show service-module"

Module type is T1/fractional
    Hardware revision is 0.88, Software revision is 20040131-0.3,
    Image checksum is 0x873E3B7E, Protocol revision is 0.1
Transmitter is sending remote alarm.
Receiver has loss of signal, loss of frame,
Framing is ESF, Line Code is B8ZS, Current clock source is line,
Fraction has 24 timeslots (64 Kbits/sec each), Net bandwidth is 1536 Kbits/sec.
Last module self-test (done at startup): Passed
Last clearing of alarm counters 01:39:58
    loss of signal        :    1, current duration 01:39:50
    loss of frame         :    1, current duration 01:39:50
    AIS alarm             :    0,
    Remote alarm          :    0,
    Module access errors  :    0,
Total Data (last 6 15 minute intervals):
    8 Line Code Violations, 0 Path Code Violations
    0 Slip Secs, 5400 Fr Loss Secs, 1 Line Err Secs, 0 Degraded Mins
    0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 5400 Unavail Secs
Data in current interval (589 seconds elapsed):
    0 Line Code Violations, 0 Path Code Violations

>autodetect encapsulation ppp
Change this to just
 encap ppp

If this is a dedicated T1, one end should provide clocking:
 
interface serial 0/0
  service-module t1 clock source internal

The other one can remain default clock source line
Are you getting any errors on the interface? Show interface ser 0/0

no errors on the serial interface.

On the clock rate do I need to set that manually or can I just use
"service-module t1 clock source internal".

thanks

Unless specified, it will default to the standard clock rate of the T1 module which is fine.
If you are not getting any error counters, then you might want to hold off on setting the clock source.
Can you post result of "show interface serial 0/0"

Well, this is not good at all. Have you contacted the Telco support and told them that you have the CPE connected and are ready to activeate the T1?

I would demand second level support. Make sure they understand that you can't even see Carrier Detect.

So I should be getting Carrier Detect even if my clocking is off?

Yes, unless your channel assignment is off. Are you sure you have all 24 channels of a full T1?

If it is showing looped, then Verizon must still be troubleshooting with a loop in their system somewhere.
