7200 STM4 Port Adapter

[Ali Norouzi]

Hello,

I'm using PA-SON-OC3 on 7200VXR (NPE-G1). I want to upgrade the link to OC12 with same wavelenght. I found PA-SRP-OC12SMI for this purpose but I'm not sure about compatiblity. Please leave your comments on this topic.

The 7200, no matter the NPE used, does not support SDH OC-12. You need a much faster router for that.

Hello Ali,

PA-SRP-OC12SMI=

DPT-OC12 Single-mode intermediate port adapter

this kind of PA is used for a Cisco proprietary WAN techology SRP DPT that implements an SDH  dual ring

the PA has two SDH connections and it cannot be used as a  simple SDH WAN link

As Paolo has noted, there is no OC-12 plain SDH/Sonet PA available for C7200 see
