The zoned cross-aisle cabling system results in shorter jumpers and thereby reduces horizontal
jumper pileup.
3.3 Ratio of Cross-Aisle Ties
The ratio of cross-aisle ties to the number of equipment terminations in a bay may vary
greatly, depending on the design of the lineups. Cable considerations include:
• Quantity of DSX terminations in each bay. Typical seven foot DSX bays may have from
450 to 1008 terminations.
• Spread of equipment terminations within each bay. If multiplexers and digital switch
terminations are located in the same bay, fewer cross-connect wires will leave that bay
than if the multiplexers and switch terminations are located in different bays.
• Short cross-connect concept. Preferential assignment or software is used always to select
the shortest possible cross-connect.
