Real, working circuit using SDH framing:

Juniper:
chassis {
    fpc 1 {
        pic 2 {
            framing sdh;
        }
    }
}
interfaces {
    so-1/2/1 {
        clocking external;
        encapsulation ppp;
        sonet-options {
            rfc-2615;
        }
        unit 0 {
             family inet {
                address x.y.3.199/31;
            }
         }
    }
}

Cisco:
interface POS3/0
 ip address x.y.3.198 255.255.255.254
 encapsulation ppp
 crc 32
 pos framing sdh
 pos scramble-atm
 pos flag c2 22


For back to back you should set one side to internal clocking, of course.
