Product Description
KTH178-5 Optical Fiber Emergency Telephone Host
KTH178-5 is an outdoor waterproof emergency telephone
host specially developed for the needs of industry
users. Voice transmission adopts standard SIP protocol,
which is perfectly compatible with all mainstream
platforms based on SIP, including SIP PBX / soft switch
/ IMS. Surface shell is made by high-intensity metallic
materials. The shell adopts waterproof and dust-proof
design, and the standard reaches IP66. It is a reliable
emergency telephone that can effectively prevent rain,
water spray, floating dust, and reduce the damage
caused by man-made malicious hard objects. The product
adopts advanced DSP noise reduction algorithm and
omnidirectional sound pickup technology. While
effectively eliminating the background noise during the
call, the distance of the sound pickup is also
optimized to ensure that users can obtain high-quality
voice communication quality under any circumstances.
The built-in ring network access module can be
connected to the ring network through optical fiber or
directly through the network cable.
Functional Superiority
1.Built-in dynamic noise reduction to ensure a
high-quality communication
2.Sealed design with IP66 waterproof and dust-proof
3.Made by stainless steel panel to ensure Ik10 standard
impact resistance
4.The maximum number of supported phones is optional 16
or 32.
