有关DSL的几个英语术语...

近日阅读有关DSL的一篇文章，遇到几个专业术语，查了许多词典，仍无果。求教于各位同好。谢谢！ UDSL, in essence, would allow service providers to offer all DMT-based services — ADSL1, ADSL2, ADSL2+, VDSL1 and VDSL2 — from one line card or home gateway, while supporting aggregate upstream plus downstream data rates up to 200 Mbps (up to 100 Mbps symmetric) up to 6,000 feet from the CO. home gateway是本地网关？还是家庭网关？还是？？

ILECs might have their savior in the automated MDF. As its name implies, the automated MDF replaces the manual technician’s work with either a series of small robots or MEMS-based electromechanical relays controlled from a remote location. Given the nascent market for such products, vendors are taking varied paths to solve the problem. Oki and its OEM partners NHC (ControlPoint) and CommScope (netSet) are utilizing a series of miniature robots that can remotely connect and DSL and POTS service by installing connection pins on a multi-layer matrix board. matrix board是矩阵板吗？还是其它？

Like many independent ILECs, Atlantic began to outgrow its local network. Since the early 1980s, Atlantic Telephone’s switching network consisted of a Siemens EWSD host switch and switch remotes. These remote switches were placed in either small offices or concrete huts for voice services. To deliver DSL, Atlantic had overlaid a DSLAM in that same cabinet or hut. switch remotes是什么东西？注意：不是remote switches！
