ABSTRACT:
When it is determined, within a local exchange company (LEC) central office of a switched integrated network access (INA) network, that there are insufficient links to handle a terminating call to a competitive LEC (C-LEC) customer, the apparent status of the C-LEC customer is changed the LEC central office, such that, if the terminating call is received by the LEC central office from a C-LEC switch, the C-LEC customer will appear to the C-LEC switch to be unavailable to receive the terminating call, even though the C-LEC customer is in fact not off hook. The present invention avoids the prior-art inefficiencies associated with having time slots for C-LEC customers permanently nailed up by the LEC central office.
