Wide Area Networks

This WAN tech has a speed of 56 Kbps,

existing wires use only one twisted pair.

Analog signals are used through the local loop

• Plain Old Telephone Service (POTS)

• T1

• T3

• Ethernet

This WAN tech has a speed of 1.544 Mbps / 44.736 Mbps,

these lines usually run over two pairs of STP cabling

Can also run over other media like coaxial, fiber optic, or satellite.

• T1 / T3

• E1 / E3

• J1 / J3

• OC - 1

This WAN tech has a speed of 2.048 Mbps / 34.368 Mbps,

This system is widely deployed in Europe.

• T1 / T3

• E1 / E3

• J1 / J3

• OC - 1

This WAN tech has a speed of 1.544 Mbps / 32.064 Mbps,

This system is widely deployed in Japan

• T1 / T3

• E1 / E3

• J1 / J3

• OC - 1

This WAN tech has a speed of 51.84 Mbps and uses it as it's base,

this system uses wavelength division multiplexing (WDM) to increase capacity of communication over fiber optic cabling.

• T1 / T3

• E1 / E3

• J1 / J3

• OC - 1

This is the collection of equipment that makes up the WAN network. It is owned and maintained by telecommunication companies. The physical structure varies and different networks with common connection points may overlap.

• WAN cloud

• Local Loop

• Demarc

• Customer Premises Equipment (CPE)

• Packet switching exchange (PSE)

This is the cable that extends from the central office to the customer location. This is owned and maintained by the WAN service provider.

It usually uses UTP, but it can also be implemented using fiber optic cabling or other media.

• Local Loop

• Demarc

• Customer Premises Equipment (CPE)

• Packet switching exchange (PSE)

When you contract with a local exchange carrier (LEC) for data or telephone services, the LEC installs a physical cable and a termination jack on the organization's premises. This marks the boundary between the telco equipment and the organization's network or telephone system.

• Local Loop

• Demarc

• Customer Premises Equipment (CPE)

• Packet switching exchange (PSE)

Devices physically located on the subscriber's premises are referred to as this.

This includes both the wiring and devices that the subscriber owns and the equipment leased from the WAN provider. Can include the smart jack, demarc, local loop, copper line drivers, and repeaters.

• WAN cloud

• Local Loop

• Demarc

• Customer Premises Equipment (CPE)

• Packet switching exchange (PSE)

This is a mega switch computer capable of handling an extremely large numbers of packets. Its job is to decide the circuit each packet will take. It is typically located in the central offices just inside the cloud.
