Setting up fax server with Brooktrout TR1034+P8H-T1-1N to receive faxes through TN464F DS1 board in Avaya Definity (has an amphenol connection.)
1. Brooktrout support said that Avaya sells a cable that would meet our needs. But Brooktrout did not know the current part number.
It is a 4 or 8 conductor cable that is amphenol on one end and RJ45/RJ48 on the other pairing 1&2 and 4&5
I believe we will need such a cable that is 25 ft long.
I was unable to find a part number in the short search I did.
2. Brooktrout support noted that a TA120 CSU pack is not necessary and will interfere.
3. Also Brooktrout support noted the settings that the fax board is looking for on the phone system side:
PRI configuration
The PBX should be the T1 clock master
Framing = ESF
Line Coding = BZ8S
Signalling = 5ESS, protocol=NI2
Channel 24 should be the D channel.
Channel 1-8 should be active for bidirectional communication
Channel 9-23 should be disabled/inactive
Incoming calls should start on port 8 and hunt backwards to port 1
On a call collision or Glare: the phone system should yield

Wi-Finally: Security that works: "The security of Wi-Fi has largely been a joke. Wireless vendors have routinely shipped their products with all of their security features turned off, rather than take support calls from end users when things didn't work. Fortunately, the pieces are now in place for you to have safe and secure Wi-Fi networking, wherever you may roam."

Problem
Outlook uses UDP for messages notices. If there is filtering or errors sending the UDP packets Outlook may not refresh the new messages on your client until you click another folder or something to force a refresh.
Information
The Outlook Find feature and the new mail notifications do not work after you apply Windows XP Service Pack 2: "To turn on RPC Polling in Outlook 2002"

Grounding and Bonding Datacom Systems: "Telecommunications main grounding busbar (TMGB). The TMGB is the dedicated extension of the building grounding electrode system for the datacom infrastructure. Because it's the central attachment point for TBBs and equipment, it should have easy access by datacom personnel.
The TMGB is a predrilled copper bus bar with standard NEMA bolt-hole sizing and spacing for the particular lug connection used. It should be large enough to satisfy today's applications and accommodate future growth. The TMGB should have a minimum thickness of 6 mm and width of 100 mm. You'll find varieties of ground bars available, and some come as a kit you can customize to meet specific requirements of the application. Pre-welded exothermic pigtails are available in a variety of conductor sizes and lengths, insulated or bare, ready for your attachment to the building ground.
Electrotin plating results in reduced resistance. However, you must completely clean any mating surfaces if they're not plated. If you have datacom panelboards located with the TMGB, you must bond the alternating current equipment ground bus (or metallic enclosure) of each to the TMGB/TGB. Make sure you maintain appropriate clearances when locating TMGBs as close as possible to the panelboards."

USB 1.1, USB 2.0, Firewire 1394a, Firewire 1394b (Firewire 800) Comparison Chart: "USB 2.0
USB 1.1, USB 2.0, and Firewire Comparison Chart:
Max. Burst Transfer Rate
USB 2.0 - Capacities
Maximum cable length (USB 2.0): 5 meters
Maximum cable length (USB 1.1): 3 meters
Maximum hubs connected in series: 5
Maximum devices connected in series: 127
The Universal Serial Bus (USB) interface connects computers to mice, digital cameras, scanners, printers, handhelds, and other peripherals.
USB 2.0, available on desktop computers and on laptops, raises the data-transfer speed from 12 Mbps to 480 Mbps and brings the technology to the most demanding peripherals, such as camcorders, portable CD-RW drives, or external hard drives.
Most new mainstream PCs have at least one USB 2.0 port, which lets you connect not only dozens of new USB 2.0 devices but also the thousands of USB 1.1 devices on the market. Connecting a USB 1.1 device to a USB 2.0 port, however, will still yield a maximum througHPut of only 12 Mbps."
