Topic: BT Openreach ONTs for FTTP (Read 24363 times)

burakkucat · « **on:** January 20, 2012, 04:51:07 AM »

For its FTTP service, BT Openreach currently have two CPE (customer premises equipment) ONTs (optical network terminals) available.

Just like the VDSL2 CPE modems for its FTTC service, the CPE ONTs are manufactured by Huawei and ECI.

The image attached (from a publicly available BT Openreach document [1]) shows both ONTs, side by side.

Do we have any members with a FTTP service?

Thank you for posting those very interesting pictures, DT3000. I suspect that Asbokid is already pouring over them with a magnifying glass and making comprehensive notes.

Indeed. I'm wondering about chip markings. What CPU is in it? Presumably running Linux (what else?!)

cheers, a
