Line buildout settings are an inherent part of T1 and T3 network element transmission circuitry.
Because cable lengths between network elements and DSX vary in the central office, LBO settings
are designed to adjust the output power of the transmission signal to achieve equal level point (ELP)
at the DSX. Most network elements allow LBO settings to be adjusted via software or
hardware settings.

For a major service provider in Canada providing services both as an ILEC and CLEC, DS1 remains a
viable business—not a growth business, but one with a large number of circuits and operating efficiency
that helps DS1s remain profitable. Recently, however, demand for DS3 services both to and
beyond the demarc has become a more common service request. For this service provider, finding
solutions for these applications was not the challenge. The challenge was to deploy extended-reach
DS3 solutions today that would not threaten operating efficiency and network reliability as the
number of DS3 circuits in the network grows....

A universal truth in network design is that all active equipment will require upgrades and
replacement. Software patches can be required as soon as 30 days after installation. Upgrades to
an existing platform, changes often required to maintain vendor support, will certainly follow over
the years. Complete replacement due to new technologies or discontinued support can occur
within 10 years of commissioning.

Limited floor space and smaller fiber counts often dictate that
multiple pieces of communications apparatus share common
equipment racks. The FL1000 is designed to be mounted within
standard 19-inch EIA equipment racks. The standard flush-mount
capability also makes this panel well-suited to cabinet installations.

A global telecommunications manufacturer recently moved into a new 500,000-square-foot world headquarters facility housing just under 5,000 employees. Two major wireless service providers supplied service to a majority of the company’s mobile phone users. Nearly 60 percent of those phone users at the new campus complained they could not make or receive wireless calls within the facility.

Mobile operators in Europe are being squeezed on several fronts, not least of which is
space. Explosive growth from popular voice services has forced them to continuously
increase the capacity of their backhaul networks consisting largely of leased lines that
connect to terminating multiplexers. Increasingly, space is becoming precious—and
expensive—real estate in remote cabinets housing this equipment.

ADC's OmniReach™ Indoor Fiber Distribution Terminal (iFDT) provides Multiple Dwelling Unit
(MDU) applications with a compact and secure family of enclosures by connecting fiber cables at
MDUs. The IFDT products utilize a rugged double-hinged design that effectively isolates the splicing
and cable termination in the rear compartment from the jumper interconnection in the front
compartment. Separating the cable splicing and termination into a layered configuration provides
a space efficient and craft friendly interface unit. The layered IFDT staggered interconnection
field provides ease of access to all connections. The IFDT enclosure provides standard SC-APC
connections and parking adapters for locating the connectorized pigtails prior to deployment....

A wireless service provider sought to minimize both capital and
operating expenses by redesigning its data centers. Major network
elements chosen for the data centers included Cisco 7500 routers,
Cisco Catalyst 6509 Ethernet switches and other data servers—each
with unique connection requirements. After initial installation, it was
highly likely that servers would be added and changed while at some
point in the near-future, software would require upgrades. Experience
taught network planners that new routers, switches and servers
alone presented only part of a sound design for data centers on the
10/100Base-T and Gigabit Ethernet network....

zoning requirements prohibit deployment of
traditional base station network equipment.
The SCS distributed antenna system (DAS)
utilizes patented digital RF transport-overfiber
technology to distribute wireless
service between existing cell sites and SCS
remote antenna units. The small-form-factor,
environmentally hardened, Remote Units

One of the greatest challenges facing mobile operators today is reducing the cost of the
backhaul portion of their network, while increasing reliability and revenue generating
opportunities. Additionally, mobile operators need to be sure that the backhaul transport
solution is capable of addressing the traditional 1 and 2G-based Radio Access Networks
(RANs) as well as the 3G-based RANs. The number of 3G-based RANs will grow driven by
new services with higher bandwidth that enable end-users to get broadband access through
their mobile devices....

With all the issues and considerations associated with pushing optical fiber
and equipment closer to the end user, it’s imperative that carriers don’t neglect
their most important resource – the network technician. Although some
responsibilities may differ with each section of the fiber-to-the-premise (FTTP)
architecture, there are also some basic procedures that apply from end to end.

The ADC Outdoor Fiber Distribution Terminal 48F (oFDT-48) is designed to terminate, splice
and interconnect fiber optic cables in an outdoor environment. This terminal may be adapted to
Fiber-to-The-Premise (FTTP) Multiple Dwelling Unit (MDU) applications by mounting the enclosure
to the exterior surface of a dwelling and connecting between the distribution cable and drops
routed to individual living units. The oFDT-48 is typically divided into two side-by-side sections
with distribution cable routed into one side and drop cable routed into the other side. The cables
meet at a central connector field that includes termination for the distribution cable and parking
for the drop cables. Each side of...
