We've used cans similar for repeaters in the past - has (I think) 4 slots in a cage inside the can... Although the cover's white, not stainless...

It's mostly semantics ADC actually calls their doublers repeaters. Technically a repeater receives the T1 amplifies it and sends it down the span noise errors and all whereas a doubler strips the DS1 out of the incoming carrier cleans it up (error correction) puts it back on a carrier and sends it down the loop. A doubler also has the "smarts" to report span conditions to the line unit as aid in trouble shooting the span.

There are T1 repeater housings the upper is a pole mounted pressurized 4 slot and the lower is I think the same in 12 slots.

Wow, thanks Wayne.

I always wondered what those white square boxes were. I figured they were repeaters for some sort of data service from the telco (DSL or T1s). I also see those can's, both in stainless and white. Sometimes the white ones have numbers written on them (looks like a simple sharpie marker wrote on it).

We have a pairgain HDSL unit at work that feeds an Adtran CSU/DSU. We have 8 channels for data and 16 channels for voice. We had problems in the past and the telco guys were in with some fancy Sunrise Telecom meters. Everythings good now though.
