Explanation

Residential cabling is classified under TIA-570 into two grades. Grade 1 is the minimum/basic standard, supporting traditional services: telephone (voice), basic data (internet), and television (cable/satellite TV). Grade 2 is the enhanced standard, which adds support for multimedia applications such as home theater, high-speed networking, and advanced AV distribution. Multimedia is therefore associated with Grade 2, not Grade 1, making it the service NOT typical of Grade 1.
