SLIC - 1. Subscriber Line Interface Circuit, see Line Card. 2. The
equipment used with the AT&T (Lucent) SLCC Subscriber Loop
Carrier Circuit, a system used to multiplex a number of subscriber
loops onto a single circuit to reduce fixed costs.
SLIP - (Serial Line Interface Protocol) - SLIP software allows Internet
