Metallic Test Access and Ring Generation Card

Overview

The MALC is a full-featured Broadband Loop Carrier (BLC) optimized for delivering voice, data, and video services over a pure packet access network. MALC gives carriers the flexibility to cost-effectively deliver Analog and Packet Voice services over existing facilities.
