This is an ultraweenie permutation of Centrex. It was created by setting up little Centrex subgroups in the regular Centrex ports of the switch. It is more expensive than regular Centrex, but can be applied to residential lines (as opposed to regular Centrex which is strictly business). Pac*Bell's inferior (well, what would you expect?) manifestation of this beast only allows transferring calls between "extensions", not to numbers outside the group. To enforce this, you must transfer using the "intercom" code. For instance, if I want to transfer you to another line in the house, I flash the hook switch, dial #26, then hang up. If I used the directory number of the line rather than that intercom code, the connection would drop. In some switches, it is possible to fool the CO into thinking all numbers in the switch are intercom numbers, thereby enabling transferring of calls to any number in the immediate local area that are served by the same switch as the Commstar user. Da phone company would rather you not know about that, however. > [Moderator's Note: And the first version of IBT's Starline likewise > did not offer this, but the later version allows transfer of a call to > anywhere -- on your premises or off-premises. PT] I understand this will be an offering bundled with the CLASS features that will be offered to Pac*Bell subscribers somewhere around Stardate 6077. John Higdon | P. O.
