HP Switches and Valcom IP Page

Sorry for the break in writing, I have been doing grunt work lately as I have been wiring up a Valcom page system that integrates Via SIP to my SwitchVox phone system. It has gone great with the exception of white noise on the over head speakers.I have been working on this with Valcom and have finally found a solution to a white noise issue on my overhead Valcom speakers. It appears that the POE from the HP 5400 series chassis has a little noise in it. Normally this is a non-issue, but with speakers from the PA being run directly off the POE the white noise comes though loud and clear.

If you are doing this install I recommend smaller 1u switches from HP or 3Com as they do not present the white noise so badly.

Cheers!

VALCOM CLOCKS

This is another example of integration betwwn older analog tech and the digital world. Digital clocks for POE network the Valcom IP Clock.

Simply add a clock to any location on the network via RJ-45 connection. Power to the clock is provided by Power-Over-Ethernet (PoE) which eliminates the need for additional costly outlets.

Consistent and accurate time across an entire organization maintains efficiency and smooth company operation:

Manufacturing Facilities – Synchronized time promotes adherence to schedules keeping the organization consistently meeting productivity goals.

Healthcare – Daily healthcare requires synchronized time schedules which are critical for patient care and timely delivery of medications.

Schools & Universities – Accurate timekeeping is crucial in transitioning students from one class to the next. Access control systems (security) require synchronized timing … doors lock at a certain time all across the campus.

Valcom IP Clock Features:

Set automatically by NTP (Network Time Protocol)

10/100BaseT Ethernet compatible

DHCP or static IP addressable

Power over Ethernet (IEEE 802.3af)

No master clock required

Simple User Control for:

IP configuration

NTP server address

Time zone offset from UTC, Daylight Savings Time

Time Display, 12/24 hour format

Status reporting

Industrial grade metal housings

Digital Clocks

2.5” or 4.0” numerals with four (4) or six (6) digit display

Red LED seven-segment display

Analog Clocks

12” or 16” round

Valcom’s IP PoE Clock Systems eliminate the need for specialized software – manage one single clock or thousands of clocks from any PC on the network.

Valcom Speakers and Paging

I will admit that page is a fairly new addition to my arsenal of education. It was an outgrowth from the SIP/VOIP side. I had worked with Roland and Bogen before but from my stand point VALCOM is definitely the winner. All speakers are connected in Parallel using cat 3 – 2 pair wire. Two of the wires Black – White are for power. The green red is the audio source. The advantage here is there is no main amp that can blow out as all of the speakers have their own amp integrated in. It also means a single span running down the hallway will support all of the speakers. They also have a wide variety of speakers for any application.

The other reason I like Valcom is for the SIP integration boxes. Currently I have a school where each zone (Building) runs off a single VIP-801. This allows the phone system (SwitchVox) to page the phones (Polycom) and the overhead simultaneously by just dialing an extension. The 801 is set up just like a SIP Phone with an easy to use interface. Very cool and it saved the school money as they did not need a speaker in every room as the phone itself repeated the page.
I will have more on this later but until I find something better Valcom is my Page System provider.
