6-conductor patch panel, make the appropriate adjustments when using the adapters. You
can also build your own 6P/6C to 8P/8C patch cables, if necessary.
• If using 4- or 6-conductor modular line cord, limit the length to 6 ft maximum. In general,
modular line cords are not twisted pair and could introduce crosstalk between line 1 and
line 2 at longer lengths.
2. Create the split to create two loop start port connections:
• In Figure 15 on
page 154
, the split to achieve two loop start ports occurs at the patch panel.
This is the recommended option.
• In Figure 16 on
page 155
, the split to achieve two loop start ports occurs at the MDF using
modular jacks.
NOTICE
Equipment Damage Hazard . Use adapters when connecting any 6-pin plug to an 8-pin jack.
Although a 6-pin plug will fit into an 8-pin jack, the plastic on the 6-pin plug housing will damage
pins 1 and 8 on the 8-pin jack. Not using adapters will increase the likelihood of failure (to pins
1 and 8 in the 8-pin jack) should that jack need to be used with an 8-pin plug in the future.
Various adapter types are available based on how you choose to connect to the patch panel.
