WARNING:
Interface lines connected to the 8-Port Voice 2-Wire Station module (model
20N30) must be connected only to telephone sets. Do not connect these sta-
tion port interface lines to Public Switched Telephone Network (PSTN) type
interfaces
!
WARNING:
If model 23A35, 23A63 or 23A64 Patch Panels are connected to devices, other
than the following PSAX I/O modules, the telecommunication interfaces that
exit the building premises must be connected to telecommunication devices
that provide primary and secondary protection:
23N33 12-Port Medium-Density DS1 IMA
23N35 24-Port High-Density DS1 Multiservice
23N64 12-Port Medium-Density DS1 Multiservice
24N64 12-Port Medium-Density DS1/E1/DS0A CES

WARNING:
The model 23A35, 23A63, and 23A64 Patch Panels are for installation only
with UL Listed Packetstar PSAX Multiservice Media Gateways.
Optical fiber telecommunication systems, their associated test sets, and similar
operating systems use semiconductor laser transmitters that emit infrared (IR)
light at wavelengths between approximately 800 nanometers (nm) and
1600 nm. The emitted light is above the red end of the visible spectrum, which is
normally not visible to the human eye. Although radiant energy at near-IR
wavelengths is officially designated invisible, some people can see the shorter
wavelength energy even at power levels several orders of magnitude below any
that have been shown to cause injury to the eye.
Conventional lasers can produce an intense beam of monochromatic light. The
term monochromaticity means a single wavelength output of pure color that
may be visible or invisible to the eye. A conventional laser produces a small-size
beam of light, and because the beam size is small, the power density (also called
irradiance) is very high. Consequently, lasers and laser products are subject to
federal and applicable state regulations as well as international standards for their
safe operation.
A conventional laser beam expands very little over distance, or is said to be very
well collimated. Thus, conventional laser irradiance remains relatively constant
over distance. However, lasers used in lightwave systems have a large beam
