I have been tasked with implementing a site over seas with limited information. Only information I have is the router type 2851, circuit type T-1, no ip addressing. and a deadline. The provider tech says that I need to configure AMI D4 and is only available to provide loops for testing. I have limited information but have configured the serial interface as a service-module t1 ami sf but the interface remains down down. Also this is a point 2 point connection. Help.
a few comments:
-since its a site overseas, doublecheck with the telco if its a T1 or E1.
-you can perform an internal loopback on the module. set the serial interface encapsulation to HDLC, set clock source internal, then configure an internal loopback via the loopback CLI. If the interface comes up without errors, move on to the telco and ask them to perform a loop to the demarc to see if theirs no errors. Remove the internal loopback, reconfigure the module for the ckt, and see if it comes up from the telco loop. If it doesn't come up look at the module to see what signals you are receiving (i.e DCD,etc ) and what type of errors you are getting (i.e framing,etc) and report to the telco
-Here is a link for performing loopbacks. The CLI may vary depending on the type of module you have, a WIC,PRI,VWIC,etc. Usually its "loopback local" or "loopback internal"
