Nec Telephone Systems Knowledge Base
Suitable telephone system for small hotel (25 rooms)? I am looking at different proposals to install a new, basic telephone system at our hotel to replace the old one (pulse metering and dot matrix printer!). I have received 4 or 5 quotes from different telephone companies. The prices for installation of the new consoles at reception and call logging computer software range from £3700 plus VAT for a NEC XT120 system + MyCalls software, to around £6000 + VAT for a Siemens system with Callista Lite software! Like most businesses we don't want to be paying over the odds if we don't need to, but at the same time we don't want to risk getting landed with an unreliable system (I am a firm believer that you get what you pay for). I am writing in the off chance that there is someone out there who already uses the NEC system or MyCalls sofware at their business and whether they would recommend it or not?
Park and Page Feature on PABX's? I have seen a 'Park and Page' system on NEC, Nortel and Panasonic telephone systems - it's provided through a 3rd party box. Does anyone know the manufacturer
What is the color coding for metal trunking or conduit? Is there any International Standard (like NEC and EN and others) specify the color coding for metal trunking to identify the usage such like normal power (120/250V), high power (380/600V), emergency power, fire alarm, telephone, security, CCTV, P.A./Sound system and etc. What is code number and what are the colors? This is not my answer; I am not asking for the electric cable coloring or code code. I am asking about the metal trunking casing color, what kind of color used to paint on the metal junction box and box coverplate, so that it is easily identified the content of the cable inside the trunking. The metal trunking is usually rectangle and long sharp, normally about 2 meters per length; the width could be from 100mm to 300mm or more. Usually there orange color, brown, purple, yellow and etc, identify the contents. I need to know what is the standard code for this requirement. The answer contributed by "alpha b" is wrong, because he/she answered the color code of wire cable, NOT the trunking color code which I am asking.
