AFAIK,

Each case is pressurized locally. To about 6-8 PSI to keep out moisture.

I've never seen one feeding off a pressurized section of cable.

I have found a few in manholes (not BST/att) that where pressurized via. the stub vs. an airpipe.

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.]]> http://www.dslreports.com/forum/remark,20449357 Wed, 07 May 2008 23:59:25 EDT Re: what is this on a telephone pole http://www.dslreports.com/forum/remark,20422776 SuperSync : AFAIK,

Is it done at the CO end of the span?]]> http://www.dslreports.com/forum/remark,20421331 Fri, 02 May 2008 13:14:26 EDT Re: what is this on a telephone pole http://www.dslreports.com/forum/remark,20421130 Splitpair :

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.

Laz

Doublers not repeaters my friend a repeater housing is squareish and holds 6 or 12 slots this has 4 standard 400 mechanics slots and holds 4 HDSLx or HDSL4 doublers.
