Protect an STM-1 interface.

Hello,

I have to protect an STM-1 interface that's connected to ADM device.

Currently we have only one router carrying these "unpacked" E1s and transported accross MPLS/IP network by using l2circuits.

I have made a search on Junos Documentation (http://www.juniper.net/documentation/en_US/junos15.1/topics/concept/sonet-aps-msp-overview.html) and found something about APS, however this documentation says that APS implementation doesn't work with l2circuits, I can't find anything on documentation regarding protect STM-1 using l2circuits. Can you please help find out this documentation?

Below the current scenario.

Thanks in Advance

Current scenario:

ADM ------ MX10 -------- MPLS/IP Network

Protected scenario desired:

ADM-------------MX10 ----------------------------- |

             |                                                               |--------------MPLS/IP Network

             |-------- MX10 ------------------------------|

Current configuration at unprotected router:

chassis{

    fpc 1 {
           pic 2 {
                  framing sdh;
                  vtmapping klm;
          }
     }

}
