Difference between t3-options and sonet-options under a t3 interface hierarchy

Hi,

 

What difference it will make if we add a statement like 'payload-scrambler' under t3 interface, sonet-options but NOT in t3 interface, t3-options hieracrchy ? Will it affect the circuit bring up & operation ?

 

Actually I am moving a T3 from a Cisco12816 to Juniper M120.

 

Cisco o/p :  show interface  Serial9/0:13 controller

Controller SONET 9/0, Interface Serial 9/0:13(DS3 Channel 13)

......

DSU Mode is Cisco, DSU Bandwidth limit is 44210Kbps

Payload scrambling is enabled, CRC is 32

..........................

 

I have configured my Juniper as per below ..but interface didn't come up when other team migrated the circuit from cisco to juniper. And they are saying that We need to add payload-scrambler statement in t3-options , then only circuit will come up . Is that true ? if yes can anyone pls. explain the difference between sonet-options & t3-options ?

 

Original config :

user@m120>show configuration interface t3-2/3/0:6

description " T3 Interface ";

encapsulation ppp;

sonet-options {

fcs 32;

payload-scrambler;

}

 unit 0 {

........

}

 

Final working config :

 user@m120>show configuration interface t3-2/3/0:6

description " T3 Interface ";

encapsulation ppp;

sonet-options {

fcs 32;

payload-scrambler;

}

t3-options{

compatibility-mode digital-link;

payload-scrambler;

}

 

 unit 0 {

........

}

 

Thanks

Hi Pradeep

I m trying to explain you hierarchy and configuration of ( T3/E3 and SONET/SDH ) interfaces.



T3 Hierarchy Level

[edit interfaces t3-fpic/pic/port]

Syntax

t3-options {
    bert-algorithm algorithm;
    bert-error-rate rate;
    bert-period seconds;
    (cbit-parity | no-cbit-parity);
    compatibility-mode (digital-link | kentrox | larscom) <subrate value>;
    fcs (32 | 16);
    (feac-loop-respond | no-feac-loop-respond);
    idle-cycle-flag value;
    (long-buildout | no-long-buildout);
    loopback (local | remote);
    start-end-flag value;
}

    unit 0
{

}

-------------------------------------------------------------------------------------

 

Sonet/SDH Hierarchy Level

[edit interfaces so-fpc/pic/port]
set encapsulation ppp/framrelay
set DCE (Default DTE)
Note:before you configure SONET/SDH interface you should enable framing.
 set chasis fpc/pic framing SONET.
  
Syntax

    sonet-options {
    fcs (32 | 16);
    loopback (local | remote);
    path-trace trace-string;
    (payload-scrambler | no-payload-scrambler);
    rfc-2615;
    (z0-increment | no-z0-increment);

}
    Unit 0
{

}

How and where use payload-scrambler statement you can fellow the below link.
