- Telecommunications Engineer
Telecommunications Engineers or Telecom Engineers come in a variety of different types from basic circuit designers to strategic mass developments. A Telecom Engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex Electronic Switching Systems to copper telephone facilities and fiber optics.
Telecommunications is a diverse field of engineering including electronics, civil, structural, and electrical engineering as well as being a political and social ambassador, a little bit of accounting and a lot of project management. Ultimately, Telecom Engineers are responsible for providing the method that customers can get telephone and high speed data services.
Telecom Engineers use a variety of different equipment and transport media available from a multitude of manufacturers to design the telecom network infrastructure. The most common media, often referred to as plant in the telecom industry, used by telecommunications companies today are copper,
coaxial cable, fiber, and radio.
Telecom Engineers are often expected, as most engineers are, to provide the best solution possible for the lowest cost to the company. This often leads to creative solutions to problems that often would have been designed differently without the budget constraints dictated by modern society. In the earlier days of the telecom industry massive amounts of cable were placed that were never used or have been replaced by modern technology such as
fiber optic cableand digital multiplexing techniques.
Telecom Engineers are also responsible for keeping the records of the companies’ equipment and facilities and assigning appropriate accounting codes for purposes of taxes and maintenance. As telecom engineers responsible for budgeting and overseeing projects and keeping records of equipment, facilities and plant the telecom engineer is not only an engineer but an accounting assistant or bookkeeper (if not an accountant) and a project manager as well.
Telecom Equipment Engineer
A Telecom Equipment Engineer is an Electronics Engineer that designs equipment such as routers, switches, multiplexers, and other specialized computer/electronics equipment designed to be used in the telecommunication network infrastructure.
Central Office Engineer
A Central Office Engineer is responsible for designing and overseeing the implementation of telecommunications equipment in a
Central Office(CO for short), also referred to as a Wire Center or Telephone Exchange. A CO Engineer is responsible for integrating new technology into the existing network, assigning the equipments location in the wire center and providing power, clocking (for digital equipment) and alarm monitoring facilities for the new equipment. The CO Engineer is also responsible for providing more power, clocking, and alarm monitoring facilities if there isn’t currently enough available to support the new equipment being installed. Finally, the CO Engineer is responsible for designing how the massive amounts of cable will be distributed to various equipment and wiring frames throughout the wire center and overseeing the installation and turn up of all new equipment.
As Structural Engineers, CO Engineers are responsible for the structural design and placement of racking and bays for the equipment to be installed in as well as for the plant to be placed on.
Electrical Engineers, CO Engineers are responsible for the resistance, capacitance, and inductance (RCL) design of all new plant to ensure telephone service is clear and crisp and data service is clean as well as reliable. Attenuation and loop loss calculations are required to determine cable length and size required to provide the service called for. In addition power requirements have to be calculated and provided for to power any electronic equipment being placed in the wire center.
Outside Plant Engineer
Outside Plant Engineers or OSP Engineers are also often called Field Engineers as they often spend a great deal of time in the field taking notes about the civil environment, aerial, above ground, and below ground. OSP Engineers are responsible for taking plant (copper, fiber, etc.) from a wire center to a distribution point or destination point directly. If a distribution point design is used then a cross connect box is placed in a strategic location to feed a determined distribution area.
The cross connect box, also known as a service area interface is then installed to allow connections to be made more easily from the wire center to the destination point and ties up fewer facilities by not having dedication facilities from the wire center to every destination point. The plant is then taken directly to its destination point or to another small closure called a pedestal where access can also be gained to the plant if necessary. These access points are preferred as they allow faster repair times for customers and save telephone operating companies large amounts of money.
The plant facilities can be delivered via underground facilities, either direct buried or through conduit or in some cases laid under water, via aerial facilities such as telephone or power poles, or via microwave radio signals for long distances where either of the other two methods is too costly.
As Structural Engineers, OSP Engineers are responsible for the structural design and placement of cellular towers and telephone poles as well as calculating pole capabilities of existing telephone or power poles new plant is being added onto. Structural calculations are required when boring under heavy traffic areas such as highways or when attaching to other structures such as bridges. Shoring also has to be taken into consideration for larger trenches or pits. Conduit structures often include encasements of slurry that needs to be designed to support the structure and withstand the environment around it (soil type, high traffic areas, etc.).
As Electrical Engineers, OSP Engineers are responsible for the resistance, capacitance, and inductance (RCL) design of all new plant to ensure telephone service is clear and crisp and data service is clean as well as reliable. Attenuation and loop loss calculations are required to determine cable length and size required to provide the service called for. In addition power requirements have to be calculated and provided for to power any electronic equipment being placed in the field. Ground potential has to be taken into consideration when placing equipment, facilities, and plant in the field to account for lightning strikes, high voltage intercept from improperly grounded or broken power company facilities, and from various sources of electromagnetic interference.
Civil Engineers, OSP Engineers are responsible for drawing up plans, either by hand or using Computer Aided Drafting (CAD) software, for how telecom plant facilities will be placed. Often when working with municipalities trenching or boring permits are required and drawings must be made for these. Often these drawings include about 70% or so of the detailed information required to pave a road or add a turn lane to an existing street. Structural calculations are required when boring under heavy traffic areas such as highways or when attaching to other structures such as bridges. As Civil Engineers Telecom Engineers provide the modern communications backbone for all technological communications distributed throughout civilizations today.
Unique to Telecom Engineering is the use of air core cable which requires an extensive network of air handling equipment such as compressors, manifolds, regulators and hundreds of miles of air pipe per system that connects to pressurized splice cases all designed to pressurize this special form of copper cable to keep moisture out and provide a clean signal to the customer.
As Political and Social Ambassador, the OSP Engineer is the telephone operating companies’ face and voice to the local authorities and other utilities. OSP Engineers often meet with municipalities, construction companies and other utility companies to address their concerns and educate them about how the telephone utility works and operates. Additionally, the OSP Engineer has to secure real estate to place outside facilities on such as an easement to place a cross connect box on.
