I agree with your quick answer version, Denver. Let me expand a bit more, if I may, and focus a bit more on some other implications, as they might relate to breadth of services, and "scale." Most of the DLC hardware platforms that were produced under the parameters set forth in previous generation designs were based on T1s at 1.544 Mb/s and T2s (the equivalent of 4 T1s) operating at 6.3 Mb/s, tops. These "T" carrier services are/were supported by twisted pair feeder and distribution plant. In some cases, there may also have been T1Cs operating at 3.15 Mb/s (the equivalent of two T1s). These Ts were historically supported by non-loaded twisted pairs, and perhaps short haul microwave systems (that made up a part or in their entirety) in some sparsely populated areas. Thus, the resulting number and speeds of delivered services were limited to those of either plain vanilla DS0-based POTS, and/or low speed analog and digital private lines, PBX-extensions, 2B+D ISDN, and the like. But nothing along the lines of what is now available in most newer DLCs, which meet the requirements of fiber-optioned GR-303 NGDLC parameters. NGDLCs employ engines which are designed to be supported by fiber (in addition to tp or microwave, where either of those are chosen instead), and their potential to deliver greater speeds is therefore enhanced dramatically. So that, a DLC might deliver to individual end users the higher capacities we've now grown accustomed to, such as full T1s (instead of fractions thereof), or T2s, as well as - or in addition to - POTS and DSL services, as well. Where fiber or some other form of high speed transport is not extended into the field, however, the choices will again be limited to the lower-speed services that were prevalent on tp. Now, let's hear from the boss when it comes to DLCs. It's WTC's turn. Regards, Frank Coluccio
