Telephones for Noisy Data Centers
All, I'd be OK if we were in a facility that was only average in terms of noise, but we are not. I need an exceptional phone for the data center. Something that doesn't transmit the horrible background noise to the other end, and something that is loud without being painful for the user of this phone. Cordless would be very fine, headset is excellent. Ordinary desk phone is OK... but the most important thing is that it works for clear communication. A loud ringer would great too... but if the best phone doesn't have one, I'll get an auxiliary ringer. Does anyone have a phone model that they find to be excellent in a louder than usual data center? Thanks! Mike -- Michael J.

Telephones for Noisy Data Centers
The ones I can recommend in that line are the headsets from David Clark. I've used these for decades in some of the harshest noise locations with great success. While most of the adaptors I use are home made I suspect that they can supply one for about any application. They have for me. http://www.davidclark.com/ regards Rick Try noice-canceling aviation headsets (GA or helicopter models have truly amazing noise suppression). High-end models come with cellphone interface. I don't think cellphones will work in many data centers, but I think rigging interface from a normal cordless phone to the headset is pretty simple. The better of these headsets (Bose X, Sennheiser HMC460, Zulu Lightspeed, etc) have additional digital signal processing for getting voice out of noise - if you don't mind expense:) --vadim > Michael J McCafferty wrote: > > All, > > I'd be OK if we were in a facility that was only average in terms of > > noise, but we are not.

Re: Telephones for Noisy Data Centers
I have similar experience in various equinix datacenters. I finally resorted to using a blue-tooth capable phone and bringing in my Aviation ANR headset with blootooth capabilities. It's a pricey headset for just using in a datacenter, but, I love having it in the airplane and it also works well in the datacenter. It's called a Lightspeed Zulu ANR headset. http://www.lightspeedaviation.com/content.cfm/Products/Zulu Owen On Jun 17, 2009, at 6:31 PM, Michael J McCafferty wrote: All, I'd be OK if we were in a facility that was only average in terms of noise, but we are not.

As much as I love my Jawbone (first gen model) I've never found it loud enough to work well in most datacenters. The person on the other end of the phone can hear you clearly due to it's excellent noise cancellation, but even at top volume on the both the phone and the Jawbone it's normally difficult to hear them. (And that's presuming you can actually work out how to use it's volume control to turn it up) It may just be mine, or the first gen models - not sure. Scott.

I actually have one of those... but when my car came with built-in Bluetooth speaker phone, I haven't used it since. I'll dig it up and I'll try it out in the data center for the near-term.

Replace microphone element with noise-canceling microphone. Best one is Roanwell Confidencer available from Mike Sandman, Graybar, etc. Also good is Walker - Clarity NoiseCensor or Allen-Tel GB117 (available from Graybar). For exceptionally loud areas, an amplified handset such as Allen-Tel GBG6M-44 as well. The noise-canceling microphone is the key. It will help you be heard at the other end and kill the noise in the sidetone to you. Works wonders. The 2500 desk phone has a dual-gong mechanical ringer, loud and distinctive. 2554 wall model is single gong, still fairly loud. Google for suppliers of these items if you aren't near a Graybar. -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV

RE: Telephones for Noisy Data Centers
I use the Peltor Bluetooth headset in our datacenter. Works better than most earplugs for noise attenuation, plus as a cell phone headset it has the noise cancelling microphone. The construction quality is really good, it could be used on a construction site without issues. I highly recommend it. http://www.peltor.se/int/Product.asp?PageNumber=144&ProductCategory_Id=9 &Product_Id=25 Thanks Sameer Khosla Managing Director Neutral Data Centers Corp. 416 682 3434 x5002 (w) 416 682 3435 (f) -Original Message- From: Michael J McCafferty [mailto:m...@m5computersecurity.com] Sent: Wednesday, June 17, 2009 9:32 PM To: nanog Subject: Telephones for Noisy Data Centers All, I'd be OK if we were in a facility that was only average in terms of noise, but we are not.

They work great. Indeed. The other solutions work great for a single user on a cellular phone, but I prefer a plain old wired telephone with a handset for the emergency phone at a data center. It's usable by anyone. Ever try handing your bluetooth headset with custom earmold to the electrician working on the UPS?

I wanted to mention that, surprisingly, the cisco 7921 wifi** voip handset (skinny only, so far...), in both g711 and g722 wideband mode (i.e. intra facility paging, noc/colo dialog, etc) has yielded simply amazing results where I've deployed or tried it within colo environments. Perhaps it's the noise canceler within the phone or some white noise-reducing aspect of g722 itself--whatever the reason, results are simply excellent. When the call is within the 'wideband capable' call manager domain, even better results seem to occur (at least that's what staff tell me...). Imagine calling your colo team and not having to repeat yourself due to noise or low-fidelity. Too bad we can't transport this (g722) over the PSTN; perhaps we'd have fewer "oops, I thought you said XYZ should be power-cycled!" experiences with them driving "remote hands" around. -Tk **In colos where I've had the chance to install .11g+.11a WIFI for customer and casual access, the coverage invariably ends up being quite good (stash enough AP1231's on 'clean' spectrum, anything works) -- but YMMV, no warranties, etc.
