Dynamic Connectivity in Just 1 RU
Telect’s 1 RU Multifunction Panel Enables DSX-1, DSX-3, Ethernet and
Fiber Optic Management Through a Space-Saving Modular Design
A
national wireless service provider
looking to create an access test point in
cell site applications faced a common
challenge – specifically, how to deploy required
capabilities in minimal available space.
Generally, low circuit counts meant that a full
DSX-1 panel, typically 3 RU or 4 RU in height,
was not an ideal solution. Similarly, with a single
DS3 running through the site, dedicating space
to a full DSX-3 panel wasn’t realistic either. In
both cases, the majority of the available
capacity in each panel would go unused, and
significant rack space would be filled with
unnecessary equipment.
Case Study
The Solution: 1 RU Multifunction Panel
To address this challenge, the wireless
company specified Telect’s 1 RU multifunctional
panel, a compact, versatile system that
incorporates a modular design to enable the
management of multiple signal types in a single
platform. Sufficient capacity fits in just 1 RU of
space (1.75 inches of vertical height) to
maximize the limited real estate available in the
typical cell site.
In this example, the provider utilized the
panel for DSX-1 and DSX-3 connectivity. Each
chassis, which mounts in standard equipment
racks, accommodates three connectivity
modules. Typical configurations included panels
with two 8-termination DSX-1 modules and a
single 2-termination DSX-3 module. In total, the
panel provided cross-connect, test, patch and
monitor capabilities for 16 T1 and two T3
circuits – again, all in just 1 EIA unit of rack
space.
Key Features and Advantages
Telect’s 1 RU multifunction panel provides
many advantages, including the following:
• Module selection: The 1 RU panel includes
DSX-1, DSX-3, Ethernet and fiber optic
module options. Within each of these are
DSX-1 configuration of Telect’s 1 RU multifunction
panel, with wire-wrap and RJ-based modules.

several options to fit the specifics of the
application. For example, DSX-1 modules
include wire-wrap configurations and RJ
interface-based products. Fiber optic
modules range from patch only to
combination patch and splice to further
maximize space. For a complete list of
module options, see the table on page 2.
• Enclosed chassis: The fully enclosed 1 RU
chassis provides better RF protection, a
key factor in wireless applications.
Furthermore, the enclosed panel enhances
the protection of individual modules to help
minimize the potential for performance
problems. In addition to the 3-module rackmount chassis, wall-mount solutions are
also available. For a complete list of
chassis options, see the table on page 2.
• Sufficient capacity: A fully loaded 1 RU
panel provides sufficient circuit capacity for
most low circuit count/network edge
applications. A DSX-1 configuration, for
example, can reach up to 24 total
terminations in just 1 RU. Fiber optic panel
densities include 36 total patch ports, if the
panel is dedicated exclusively to fiber.
Combining functionality through different
module types will typically provide more
than enough termination capacity, and is
the real advantage of the 1 RU modular
panel.
• Multifunctionality: A mentioned above,
multifunctionality in minimal space is the
true advantage of Telect’s 1 RU modular
panel. In the example detailed above, the
user dedicated the panel to DSX-1 and
DSX-3 connectivity.
Other users have configured the panel for
additional functionality. In wireless
backhaul applications, for example, the
panel can incorporate a fiber optic module
to terminate incoming fiber at a remote site;
a DSX-1 module to cross-connect to a T1
test panel; and an Ethernet module to
interface with a router. Based on the
application, the possibilities are broadranging.
Conclusion: Space Savings and Versatility
Cell sites, huts, remotes and other limitedspace environments often require a significant
deal of creativity when it comes to system
design and deployment. Although the
functionality required at the site is often
complex, the available space typically is quite
limited.
Multifunctional solutions such as Telect’s 1
RU modular panel enable versatility for
equipment and capabilities that typically are
given a low priority compared to the more costly
active gear (routers, etc.) that drives network
traffic through the site. This simple solution
helps network designers make the most of
valuable space, while at the same time
addressing the connectivity requirements that
most applications require.
