My understanding is that there is a fairly small number of pots circuits (2?) that they can bring in over the B-PON, and that moreover ISDN BRI and hicap (eg. repeatered or HDSL DS1 service) are entirely incompatible.
Circuit Emulation Services (CES) have been offered by both cable and telephone companies for serveral years. Some cable companies use CES to provision ISDN, T1, T3, etc circuits over their coaxial plant. Cable companies may be doing this only for their "high-value" customers. Telephone companies can use similar CES technology to provision circuits over FTTx or other local loop facilities. Some carriers have completely converged core networks now, so your circuit services may already be using CES. Carriers (or their vendors) think operating a converged network will be less expensive, and are trying to push the convergence closer to the customer edge. Have you noticed Comcast and other cable companies are increasing their video rates by up to 7% starting January 1, but not the price of voice or data services, even though they use the same coaxial cable for all three services?
