Low Voltage Cable

Data and Telephone cable being used in Structured Wiring applications are “Unshielded Twisted Pair” or UTP. These cables consist of multiple twisted pair in a PVC or plenum rated sheath. An example is shown here of Cat5, which has 4 twisted pair:

• Unshielded Twisted Pair

By twisting the wire pairs, the electromagnetic field generated by one wire is used to cancel out the field in the other wire of the pair. This action shields the wires from external interferences such as electromagnetic (EMI) or radio frequency (RFI).

• Signal Protection

• Megahertz

• Megabits

Megahertz is a unit of frequency, typical unit of measure would be Megahertz (MHz). If an anologywere made to a highway, Megahertz would be the number of lanes on the highway. The higher the MHz, the higher the bandwidth. Using our analogy, the more data that can be handled by that highway.

Megabits is a unit for the amount of information. A typical unit of measure would be Megabits per second (Mbps) which would measure the amount of information flowing at a given time. Using the highway anology above, Megabits per second would be the speed at which your traveling on the highway. The higher the Mbps, the more information that is flowing, the faster your traveling on the highway.

“POTS” means “plain old telephone service”. POTS cable has only two pair. It is also referred to as CAT 3 since this cable has a maximum frequency of 16 Mhz and transmits up to 16 Mbps. POTS / Cat 3 cable is not to be pulled to Siemens structured wiring enclosures.

Low Voltage Cable

• POTSCat 5 cable has four pair of wire and is acceptable for use in structured wiring applications. This cable has a maximum frequency of 100 Mhz and transmits up to 100 Mbps.

• Category 5

There are 4 cable classifications for Unshielded Twisted Pair cable.


7

Cat 5e, like Cat 5 has four pair of wire, however, it has higher capacity than standard Cat 5: maximum frequency of 350 Mhzand transmits up to 1000 Mbps. Additionally, Cat 5e has approximately 3dB stronger signal strength than Cat 5. Cat 5e is recommended for new structured wiring installations.

Low Voltage Cable

• Category 5eCat 6 cable has four pair of wire and a plastic center partition to reduce “crosstalk”on the line. Of the 4 cable types, Cat 6 has the highest capacity: a maximum frequency of 500 Mhz and transmits up to 1000 Mbps.

• Category 6

Strip off 1” to 2” of the outer jacket, exposing the colored conductors. Be sure colored wires are not damaged.

110 Punchdown Connections

1. Strip Outer Jacket

Separate each of the 4 colored pairs, and untwist the pair. Be careful, however, when untwisting the pair, not to untwist more than ½”.

2. Separate Colored Conductors

Many of the data and telephone modules offered in Siemens Structured Wiring utilize a 110 Punchdown connection. Follow these 4 steps to install Cat 5 cable into a 110 Punchdown connection.


9

Take the untwisted pair and place them in the matching colored slot on the 110 punchdown block.

110 Punchdown Connections

3. Place Conductors into Appropriate Slot

Press the tool down between each of the 8 V-blocks. Be sure to orient the tool such that the cutting blade cuts the excess wire. The punchdown tool will make the connection using the “vampire”strip on the block, and cut the excess wire in one motion.

4. Make Connection with Punchdown Tool

Connector Types

There are three types of jacks typically used for low voltage phone and data connections:

RJ stands for “Registered Jack”. The RJ-11 is the most common of this type, typically used for terminating telephone wires. It utilizes only two wires to make one phone connection.

• RJ-11The RJ-25 is also used for telephone connections. RJ-25 uses the same size jack as an RJ-11, however, it provides service for 3 phones over 6 conductors. Similarly, the RJ-14 uses this same jack size but services 2 phones with 4 wires.

• RJ-25The RJ-45 is commonly used for making ethernetconnections. This has a larger jack than the RJ-11, and utilizes 8 wires to make the network connection.

• RJ-45

3. Flatten & Trim Conductors

Push the wire firmly into the RJ-45 jack. Be sure the conductors stay in the correct order as they are inserted. Each conductor should go all the way to the tip of the jack.

4. Push Wire into Jack


13

Once the wires are inserted, carefully inspect prior to crimping. Check for 3 features:

– Primary strain relief on the sheathing

– Secondary strain relief on the conductors

– All 6 conductors are past the Insulation Displacement Contact.

RJ-45 Connectors

5. Inspect the Wires

With the inspection complete and everything correct, the jack should be crimped onto the cable. Test the connection by giving the jack a pull to insure a good crimp.

T568A is recognized as the preferred configuration. It is the required standard for all Federal projects. All Siemens products utilize T568A.

RJ-45 Connectors

• T568AT568B standard once was a widely used wiring scheme. It matches the older AT&T 258A color code, but is not common for current wiring requirements.

• T568B

There are two common wiring standards for RJ-45 Connections: T568A and T568B. These two standards were developed by the TIA, EIA and ANSI to reduce confusion in making these type connections.

Telephone Cable

While Cat3 cable may be applicable for some phone connections, Cat5 cable is recommended for telephone connections in Structured Wiring applications. Cat5e or Cat6 may be used, but the additional capacities of these cables are not needed for telephone.

• Cat5 Cable Recommended

Typical phone connections only require two wires. Because Cat5 cable includes 4 pair of wires, up to 4 different phone lines can be run over one Cat5 cable.

• 4 Phones, 1 Cable

Networkingstructured

WIRING


22

Local Area Network

A Local Area Network (or LAN) creates an interconnection of devices in a single building or group of buildings. The network can include devices such as computers, printers, and scanners.

• Networking

For computers and other devices on a Local Area Network to talk to each other, they must have a common protocol. In a home application, this protocol is typically provided by the Operation System of the computer.

• Network Protocol


23

Local Area Network

Wired network connections offer faster communication speeds and a more secure connection than wireless networks. In structured wiring applications, having a wired network also allows more flexibility for routing and re-routing incoming network connections, even if a wireless router is being used.

• Wired or Wireless?

Why have a LAN? Common applications of a LAN include:

File Sharing

Media Sharing

Print Sharing

Data Storage

• Applications


24

Hub

With a common protocol, the data will be shared between devices through a component such as a Hub. A Hub connects segments of a LAN through multiple ports. When information arrives at one port it is copied to the other ports.

• Connection Point

For computers and other devices on a Local Area Network to talk to each other, they must have a common protocol. In a home application, this protocol is typically provided by the Operation System of the computer.

• 4-Way Intersection


25

Switch

Internet Internet ServiceServiceOne difference between a hub and a switch is

that all the nodes connected to a hub share the bandwidth among themselves, while a device connected to a switch port has the full bandwidth all to itself.

Switches are used to connect computers on the same network; however they do not provide Internet access. You can still share your Internet connection through one of the computers on your network, however, if the main computer crashes, all of the other computers will lose their Internet connection. An example is shown here:

• Switch Functionality

• Full Bandwidth Available


26

Router

Internet Internet ServiceService

A Router allows you to create a home network. It gives you all the functionality of a Switch, plus additional capabilities. Like a Switch, a Router also has the ability to share the full network bandwidth for each computer on the network.

• More Functionality

A router has the ability to separates networks, allowing you to share your internet connection without being dependent on one computer’s connection. A router also provides a built in firewall for your network. An example is shown here:

• Not Dependent on 1 Computer

The Siemens DM4PRTR is a router that provides service to 4 locations.

• DM4PRTR


29

DM4PRTR

DM8PSWT

Expansion

The Siemens DM8PSWT can also be used to expand the number of locations serviced by the DM4PRTR router from 4 to 10. In this setup, the router acts as the internet provider to the switch, eliminating the need for the internet connection to first be routed to a computer.

• Expansion

To utilize the DM8PSWT for expansion, the internet connection should be routed directly into the DM4PRTR router then from the router to the switch. An example is shown here:

• Wiring Diagram



30

Data Modules

The Siemens DM8PEXP is a module that allows you to terminate Cat5 cable from outlets and connect to service through the RJ45 jacks. Connections can be made to 8 locations.

• DM8PEXP

Having the RJ45 jacks allow “plug and play” capability with a router or switch. All that is needed is a patch cord such as the Siemens AJ24 to jump from the DM8PEXP to the service. An example is shown here using a DM8PSWT switch:

• Quick Connections


31

Data Modules

Can you connect the router or switch directly to the data jack without usining the DM8PEXP? Yes, however, it is not recommended that you terminate a cable run with 110 connection on one end and RJ-45 (modular plug) on the other end. This does not conform to EIA Category 5 specifications. This is why it is recommended to utilize the data termination module when utilizing RJ45 modules.

• Is the DM8PEXP Required?


32

DSL

DSL stands for Digital Subscriber Line. This technology takes advantage of unused frequencies on the telephone wire without affecting the voice portion of the line.

• Digital Subscriber Line

DSL offers higher speeds than a traditional modem: 1500 kbps vs. 56 kbps. Also, a DSL connection can be left open without disrupting voice calls over the same line. However, DSL speed deteriorates the further you are from the providers location.

• Advantages & Disadvantages


33

DSL

The DSL connection from the telephone company will be sent through a DSL modem, then connected to a router. An example is shown here using the Siemens DM4PRTR and DM8PEXP:

• Typical Wiring

A DSL connection can be shared throughout the home even if the modem provided by the phone company is located in the home office instead of the structured wiring enclosure. In this case, Cat5 cable would be run from the office back to the enclosure and plugged into the router.

• Remote Modem


34

Cable Modems

A cable modem provides internet service by taking advantage of unused frequencies on the RG6 coax cable used to feed your television without affecting the video signal.

• Shared Coax Cable

Like DSL, cable offers higher speeds than a traditional modem: 1500 kbps vs. 56 kbps. Unlike DSL, internet speed does not degrade the further you are from the providers location.

• Advantages


35

Cable Modems

The cable company will typically provide a cable modem to convert the signal to a traditional Cat5 with an RJ45 jack. This can be plugged into a DM4PRTR Router to share the signal to the other computers in the home. An example is shown here:

• Typical Wiring
