In addition to what skip555 mentioned above, basically, if you pay for it, the Telco will do it as business class of service.
Facilities can be a problem, depending on the area and provider. If you want a cable terminal installed for 25 or 50 pairs, provide a 2-5 year forecast to the OSP engineer. The forecast is the "key" in most cases. Even if you don't come close to the forecast use, they are still happy to get one. So if you think you might do DS1 or DSL or PL ckts, put those on the forecast in addition to the residence lines you may already have. Once the cable is installed, they are not going too remove it!
Hope this helps!
