950 + Wxxx

A carrier access code for obtaining switched access to interchange carriers where (a) the calling customer accesses the IC and passes the address information, if any, in two distinct operations; (b) the calling customer usually uses in-band signals to pass the address, if any, to the IC; and (c) the EC does not repeat the address information. Note: The X digits in Wxxx are the carrier identification code for the IC, and W is 0 or 1.
