I think you must have mis-heard this one. NXX, yes; but I won't believe XXX. Using your "131" example above, there would be ambiguity when the telco received the dialling sequence 1312555. Unless it used a timeout (yuck!), the switch would be unable to distinguish between a local call to 131-2555 and a LD call to Chicago of the form 1-312-555-XXXX. The whole point of cleaning up dialling rules (as Bell of PA is doing now in 215) is to allow NXX exchanges *without* ambiguity or timeouts.
