Understand STM-1interface on ASR 1006 IOS 15

hey ,i configured a chanalized STM-1 on 7609-s router with no problem,the think is when i configured on ASR 1006 it's not the same result of interfaces maybe because 1006 run IOS 15,i try to un derstand how it work

and the result :

no ip address


interface Serial0/0/0.1/1/1/3:0

no ip address


whey the third unframed interface show 2 and the fourth show 1,what that mean ?

this is how it show me in 7609-s with 12.3 IOS

interface Serial1/0/0.1/1/1/1:0

interface Serial1/0/0.1/1/1/1:1

interface Serial1/0/0.1/1/1/2:0

interface Serial1/0/0.1/1/2/1:0


Understand STM-1interface on ASR 1006 IOS 15

After a long analyse ,i remarque that the 1006 IOS work fine,but only in the running config it sort the result in difirent way then IOS 12.4 , i don't know if it's a bug or something else.have a nice day.
