PRODUCTS
Excel manufactures an open, modular and integrated programmable switching system available in a variety of sizes and configurations. It also provides protocols and other software, interfaces, controllers and other options for use in a wide range
of telecommunications switching applications. (An index is available for accessible
product information).
PROGRAMMABLE SWITCHES
are switches that are controlled by a host computer and are typically integrated
into telecommunications applications by systems integrators, OEMs, and
VARs who in turn sell complete turnkey applications. Programmable switches
can be customized for use in a wide variety of applications such as Enhanced
Service Platforms, Wireless and Wireline Infrastructure, and Service Bureaus.

ONE Architecture (Open Network Expansion) is Excel's highly programmable, open, scalable and reliable approach to network infrastructure. ONE Architecture delivers a new standard for growth and flexibility needed to satisfy emerging and existing market requirements. Leveraging Excel’s state-of-the-art distributed switch design and powerful high-level programming tools, ONE Architecture empowers application developers and network carriers to thrive in competitive, fast-moving markets by enabling them to implement new services quickly, flexibly and economically.
Excel's major switching product and the foundation for ONE Architecture is the EXS (Expandable Switching System). Typical EXS configurations include:
| Mid- range EXS |
A non-blocking switch in the 2,000 port range, with fully redundant configurations. |
| Entry Level & Distributed EXS |
A compact PC-sized EXS implementation in the 100 to 1000 port range, designed for cost-effective distributed and mobility switching applications, capable of directly accessing voice processing resources. |
| EXS |
Available in a variety of configurations, EXS supports over 30,000 non-blocking
with fiberoptic backbone for large-scale distributed
or single premise switching environments. |
| PCX/Media Processing |
A 512 port switch in an industry standard PC (ISA bus) environment, designed for small to mid-range switching applications. Wih addition of industry-standard resource cards with telephony bus, and Excel's EXNET Connect, the PCX supports direct integration of media processing within an EXS environment. The media processing host and host interface can reside in the PCX chassis. |
| EXNET Connect |
EXNET Connect is a single board solution that integrates industry standard media processing resources directly into the EXS environment. It provides 512 full duplex ports and dedicated switching capability, so that access to these resources do not consume normal EXS switching capacity. |
| Excel's LNX,
introduced in 1988, established the technology platform for all subsequent
product offerings. Designed specifically for open programmability, high-reliability,
high performance, configurability and expandability, the system was delivered
to original equipment manufacturers and systems integrators who built host-based
enhanced service applications and integrated them with Excel switches for
resale to the telecommunications marketplace. The LNX has been incorporated as the mid-range configuration of Excel's EXS switching environment. In this range EXS supports high capacity
switching, allowing the user to configure over 2,000 ports in a single rack-mount chassis. It also integrates a wide range of functionality -- including ISDN
PRI, SS7, sub-rate
switching and digital signal processing within the switch environment
via powerful, intelligent interfaces. |
| The EXS Expandable Switching System,
introduced in 1995, is Excel's next generation of programmable switching.
EXS is a distributed switching architecture that operates as a single, logical
switch, supporting over 30,000 non-blocking ports. The architecture is
implemented over EXNET, Excel's 1.2 Gbps fiber-optic network, which can
be geographically distributed or centrally located
based on customer needs. EXS uses new chip technologies and greater memory
capacity to improve performance and support high call volumes. The EXNET
infrastructure can support a combination of switches as well as other
telecommunications services (such as wireless PCS/PCN and voice processing
resources) that can link into the network. |
| The CSN (Communications Service
Node) is a product introduced in 1996 that
is designed for environments in the 100 to over 1,000 port range. The CSN has been incorporated in Excel's EXS switching environment as an entry-level or distributed configuration. It offers
programmable non-blocking switch capabilities plus easy
connectivity to voice resources in a compact, smaller
PC footprint-sized chassis .
As an EXS configuration, it offers product line scalability
and complete compatibility of switching resources in a mid-range environment. |
| The PCX
was introduced in 1992 as the entry-level platform for Excel's family of switches.
PCX uses a PC chassis to support up to 512 ports via a rich variety of
network interfaces , and can be co-located with
the host computer as well as PC-based voice processing cards, providing
a total solution in a single PC chassis . The PCX
system uses the same software environment and API as the EXS, providing
compatibility among the systems, and allowing customers to support their
applications on either platform. |
| Excel also provides high level switch programming tools
including Programmable Protocol Language (PPL) ,
a patented software environment that gives developers a level of open programmability
unparalleled in telecommunications. With PPL, service providers have a
unique power to customize -- quickly and easily in the lab or even in the
field -- generic switching software, an environment heretofore considered
"off-limits" to customers utilizing other switching platforms.
PPL provides a program resource to deploy features, accommodate local variations
in line and signaling protocols and carry out other enhancements immediately.
Delays for new software releases from the switch vendor are eliminated,
saving time and costs, especially in remote localities. |
| Excel's product architecture delivers outstanding scalability, openness, programmability and reliability. The result for our customers is a new technology
standard for programmable switches. |
