[j-nsp] ppp problem between j2300 & Telindus 1030

[Le Hai Dang]

Hi all,

I have problem with ppp connection between j2300 & Telindus 1030
routers. NCP is not up & stops at inet "Conf-req-sent".

j2300 ---v35----- Telindus_converter -----e1------- Telindus 1030.

Just have a simple config on j2300:
==================================
root> show configuration interfaces se-0/0/2 
encapsulation ppp;
serial-options {
    clock-rate 2.0mhz;
}
unit 0 {
    family inet {
        address 192.168.3.1/30;
    }
}

Physical link & LCP is up:

+ Connecting the same e1 link from the converter to an M box shows no
problem at all. And the point here is Telindous router works well with
Cisco box in this case.

+ Traffic monitoring at serial link of j2300 shows:
