Broadban internet access at my school, anyone know what the "Office Box" provided by ntl is?

[Confused]

As the title says, at my school, we have a dedicated internet connection, coming from ntl (the telco company) via fibre, and there is a box which converts the 34Mbps signal from the fibre to 2Mbps connection via BNC (2Mbps is our connection speed), called the "Office Box".

Does anyone know what this box is, and what it does?

Thanks in advance

It's an SDH mux which is taking in the 34mb trunk and giving you a 2mb tributary for your service. This 2Mb will be mapped
back across the network into an ntl; access router.
