What equipment are we using?

You can see a general system description.
DSLAM (DSL access multiplexer). The DSLAM is a Copper Mountain CopperEdge CE-150 (PDF data sheet). It takes up four rack units (7 inches).
UPS. The UPS at the DSLAM is an APC Smart-UPS 1000 RM. The "RM" means "rack mountable". It takes up two rack units (3.5 inches). Given our modest power needs (14 watts) this UPS can power the DSLAM for about two hours. Another UPS is installed at the microwave relay point to power the Breezecom WB-10, the ethernet hub, and the Netopia R7100-C router at that location.
Racking. We use a rack cabinet that provides six rack units of space (10.5 inches). The rack rails are horizontal and the racked equipment (the DSLAM and the UPS) hang down vertically.
Splitters. The central office splitter we are using is the 16-line Siecor COSB16S1W02L central office splitter (photo, four-page PDF data sheet and two-page PDF color brochure). At the subscriber homes we are using a Siecor SPS-H70-SR1 outdoor POTS splitter (photo, four-page PDF data sheet and one-page PDF color brochure).
DSL line card. We are using a CopperEdge SDSL line card (PDF data sheet). It has 24 ports. We are also using a CopperEdge G.Lite ADSL card (PDF data sheet) with 24 ports.
SDSL modems. Copper Mountain makes an SDSL modem (PDF data sheet) and provides an SDSL compatibility list. We have performed tests and have identified four modems that we find work well (including one 3Com modem that does not appear on Copper Mountain's list). Note that the 3Com and Netopia products are actually made by Copper Mountain. We also use Netopia R7100-C routers (PDF data sheet) for uplink from the DSLAM to our T1 line.
ADSL modems. We use the Alcatel Speed Touch Home modem.
Microwave link. As may be seen in the writeup of our point-to-point microwave link, the microwave gear is by Breezecom.
Protectors. To protect the DSLAM, we are using ITWLinx Ultron solid-state protectors and you can see a photograph of them. We use UP2H-16 protectors which have a 16-volt clamping voltage.
