There could be any number of reasons that your voice and data system may be changing. You might be adding more PCs or phone lines; adding a dedicated server to store critical data or adding scanners or printers to more adequately serve customer needs.
In order to ensure a seamless transition into your larger, upgraded network there’s a very good chance that you’ll need upgrades or
A patch panel is an in-line series of connections mounted onto a frame to enable network cables to be terminated in an orderly manner. Typically, the panel is the termination point of network cabling drops that are installed in a office or residential cabling system.It is numbered and comes in 12-port, 24-port, 48-port and 96-port configurations. The numbering of the panel ports allows for the network installer to label the wallplates to match the corresponding connection at the patch panel.
Patch panels are most commonly used for computer data networks but as Voice Over Internet Protocol (VOIP) phone systems become more common, we are seeing phone systems being terminated into panels. They are wall or rack-mounted. In small offices, a 12 or 24-port patch panel might be wall-mounted to a wooden mounting board. Larger office networks will usually require a rack mounted series of panels.
The patch panel comes in Cat5, Cat5e and Cat6 types to match the cable being installed. The connections on the panel are RJ45 that are designed to allow for a cable to "punch-downed" into the connector. The connector has 8 punch down points to accommodate the 4-pairs of wires in a Cat5/6 cable.
A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. A frame style, open rack (see image to the right) would have outer posts but no front or side panels. An enclosed rack has sides and a door for security and usually includes ventilating fans to keep equipment cool. Enclosures are much more expensive than open racks.
but it is larger in size and it has 4-pairs of wires rather than the 2-pairs that are found in a phone line.
panel. The patch panel is the hub of all incoming workstation network connections.
Category 6 cable, commonly referred to as Cat6, is a cable standard for Gigabit Ethernet and other network protocols that is backward compatible with the Category 5/5e standards. Cat6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 100BaseTX and 1000BaseT (Gigabit) Ethernet.
The cable contains four twisted copper wire pairs, just like earlier copper cable standards. Although Cat6 is sometimes made with 23 gauge wire, this is not a requirement; the specification states the cable may be made with 22 to 24 AWG wire, so long as the cable meets the specified testing standards. When used as a patch cable, Cat6 is normally terminated with an 8P8C modular connector, commonly referred to as an "RJ-45" connector. Cat6 connectors are made to higher standards that help reduce noise caused by crosstalk and system interference.
Some Cat6 cables are too large and may be difficult to attach to RJ45 connectors without a special modular piece and are technically not standard compliant. If components of the various cable standards are intermixed, the performance of the signal path will be limited to that of the lowest category. The maximum allowed length of a Cat6 cable is 100 meters (330 ft).
The cable is terminated in either the T568A scheme or the T568B scheme. It doesn't make any difference which is used, as they are both straight through (pin 1 to 1, pin 2 to 2, etc). Mixing T568A-terminated patch cords with T568B-terminated horizontal cables (or the reverse) does not produce pinout problems in a facility. Although it may vary slightly or sometimes degrade signal quality, this effect is marginal and certainly no greater than that produced by mixing cable brands in-channel. The T568B Scheme is by far the most widely used method of terminating patch cables.

Note that diligence is required to make sure that a non-plenum airspace stays that way. A non-plenum airspace can become a plenum airspace by accident if the ductwork is disconnected and not properly repaired. Ductwork degradation can occur due to building damage such as earthquakes, aging or adverse environment causing the metal to corrode and fall apart, or simply negligence on the part of building contractors that leave work unfinished. Discovery and repair of unintended plenums is difficult due to the hidden nature, limited space, and difficult access of most installed drop ceilings. For highest fire safety it is best to assume all drop-ceiling airspaces are plenums, whether or not they are officially designated as one.

Category 5 cable includes four twisted pairs in a single cable jacket. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and other pairs. It is most commonly used for 100 Mbit/s office computer networks, such as 100BaseTX Ethernet, although IEEE 802.3ab defines standards for 1000BaseT - Gigabit Ethernet over category 5 cable.The cable exists in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking. Taking these things into account, building wiring (for example, the wiring inside the wall that connects a wall socket to a central patch panel) is solid core, while patch cables (for example, the movable cable that plugs into the wall socket on one end and a computer on the other) are stranded. Outer insulation is typically PVC or Plenum. Plenum cable is designed to go into drop ceilings that are used as air returns for the air-conditioning systems in modern office buildings.
