OTU2 XP client port is SIGLOSS

[steve554365]

Hi,

I have OCHCC and OCHTRAIL created between two OTU2_XP cards. The OCHTRAIL is in IS state. The OCHCC is still in OOS state. Both sides show major alarm for the client port SIGLOSS Signal Loss on Data Interface. I know for sure that one side has the client 10GIG LR connection, but the other side does not yet. Is it normal to see the alarm on both sides? Should it be only on one side where client is not connected?

Also, when doing power meter testing, the side where the client is connected - the client equipment is sending the light, but when checking the light from the OTU2 XP client port, there is no light, is this also normal?

Hi Steve,

sorry for late reply.

can you please check following things,

• •1.     go to card view --- performance – optics PM – current values – refresh

            check this on both cards for client ports.

• •2.     Go to card view – provisioning – card – check for card configuration and AIS/Squelch option.

Also signal loss on data interface means we are not receiving any optical power on client port.

As you said on one side you didn’t see anything coming out from Transmit of OTU2_XP client, this is because of squelch.

So it looks like an normal behavior of the card.

Squelch function:

Switch------OTU2XP(A)-------------OTU2XP(B)----------Switch

At OTU2XP (A) if you are not receiving anything on Rx of client port connected to switch, you not transmit anything from client port of OTU2_XP(B)

And vice-versa.
