3.1 General Information about FlexDSL Orion3
The FlexDSL Orion3 SHDSL.bis Extended product family offers a broad range of products,
which are based on the latest SHDSL.bis standards (ITU-T G.991.2 & ETS TS 101 524), while
also being fully interoperable with all our existing SHDSL equipment (Orion1 & Orion2). The
FlexDSL Orion3 supports TC-PAM16/32 and the new TC-PAM4/8/64/128 line coding. The
support of these line codes ensures compatibility with existing SHDSL equipment that is already
installed, in order to protect customer investments, while at the same time providing an upgrade
path to the newest DSL technologies.
SHDSL.bis Extended allows symmetrical data and voice transmission at speeds up to 15.2Mbps
over a single pair of copper. In addition, the FlexDSL Orion3 modem range also supports DSL
channel bonding for up to 4 copper pairs in order to achieve speeds to 60.8Mbps! FlexDSL Orion3
SHDSL.bis Extended modems can provide up to 4 complete E1 interfaces, which support framed
and unframed services (G.703/G.704). An integrated 2 or 4 port Ethernet layer 2 managed switch
with VLAN support (10/100BaseT) ensures connectivity to IP services. Beside of E1 and Ethernet
we have additional interfaces like Nx64 that can be configured to be a V.35, V.36, X.21 or V.28
interface (cable selected). Also RS-232 and RS-485 (asynchrounous) are available. This makes
FlexDSL Orion3 SHDSL.bis Extended modems a perfect solution for a wide range of applications
in which TDM and IP services need to be transmitted over copper wires.
Like all FlexDSL Orion products, the Orion3 SHDSL.bis Extended modems family is based on
industrial components and is manufactured according to highest quality standards providing
additional value due to the extended temperature range and higher reliability.
