connecting OC48 Between ASR9K and ASR1K

Hi there.

 

I don't know the first thing about the  WAN something like POS...

 

Now I'm facing some problem with connecting OC48(POS) between ASR9K and ASR1K.

 

There are new 9K and new 1K  in same server rack for the test.

 

So i tried to test these for connecting OC48

 

9K and 1K is directly connected by OC48

9K : A9K-SIP-700 // SPA-2XOC48POS/RPR    // SFP-OC48-SR

1K : ASR1000-SIP10 // SPA-1XOC48-POS    // SFP-OC48-SR

 

After connecting these two devices directly, ASR1K shows the interface status is up/up 

but ASR9K ... the interface status is down/down. 

 

I didn't configure anything. Do i need to configure something ? 

 

When i connected POS port 1 and POS port 2 directly in the same ASR 9K chassis, the interface is up/up

 

please help me out 

 

Thank you in advance. :)

Did you connect the transmit

Did you connect the transmit of one device to the receive of the other?

Hello. Sorry I can't

Hello. 

Sorry I can't understand what you mean.

I just connected

ASR9K--------OC48------------ASR1K

directly. 

There's no device between ASR9K and ASR1K.

exactly, so the transmit side

exactly, so the transmit side of the 9k needs to be connected to the receive side of the 1k.

the transmit side of the 1k needs to be connected to the receive side of the 9k.
