- To be designed and provisioned per ANSI/EIA/TIA-569
- Primary function for termination of horizontal cable distribution (horizontal cross-connect)
- May contain intermediate or main cross-connects
- Provides a controlled environment to house telecommunications equipment, connecting hardware and splice closures
Cabling: Cross-connections vs. InterconnectionsCross-connections
- Equipment cables that consolidate several ports on a single connector (ie: 25-pair hub) are terminated on dedicated connecting hardware (system specific)
- The dedicated hardware is then interconnected to horizontal or backbone terminations
 Interconnections
- Equipment cables that extend a single port appearance (ie: modular hub) are permanently terminated or interconnected directly to horizontal or backbone terminations
