| 释义 | SLC 1. Schools and Libraries Corporation (SLC). See Schools and Libraries Program. 2. Subscriber Line Charge or Service Line Charge. Synonymous with Customer Access Line Charge (CALC) and now known as End User Common Line Charge (EUCL). In the United States, an access charge approved by the Federal Communications Commission (FCC) and billed by the incumbent local exchange carrier (ILEC), the SLC is intended to compensate the ILEC for the costs of connecting a call to competitive local exchange carrier (CLEC) or an interexchange carrier (IXC) through local exchange facilities (the local loop, central office, and associated equipment), maintaining the equal access database, and other related costs.The SLC applies to all ILEC local loops, but varies by type of facility (e.g., residence line, business line, and CO trunk). If the access circuit is digital in nature, a Digital Port Line Charge (DPLC) also applies. See also CLEC, DPLC, equal access, EUCL, FCC, ILEC, and IXC. |
