• The analog service is cross-connected to a modular (RJ-21X) punch-down block.
A telco cable is connected to the modular (RJ-21X) punch-down jack and runs to
a modular connector (RJ-21X) on an analog trunk patch panel.
Like the telephone cabling, patch cords are connected from the analog trunk patch
panel (RJ-11) to the voice switch patch panel (RJ-11).
NOTE As an alternative, patch panels can be replaced with punch-down blocks. This
may be more cost-effective but is less flexible.
