2. Overview: About the HDMCII VDSL2 LAN Extender Module
(Extended Temp)
HDMCII VDSL2 LAN Extender Module (Extended Temp) enables LAN and
Campus network managers, and service providers, to use an existing phone-
grade wiring to support high bandwidth Ethernet connections. Industry
standard 2Base-TL provisions symmetric data delivery over the outside plant
defined by IEEE802.3ah. 10Pass-TS transport is designed to meet short-
range, high data rate requirements over standard copper wire defined by
IEEE802.3ah for inside a plant environment. They can achieve this by using
Ethernet over VDSL where the 100m distance limitation of twisted pair data
cabling is no longer a challenge.
Designed with VDSL2 (second generation Very high-bit-rate Digital
Subscriber Line) technology, the Black Box Ethernet-to-VDSL2 converter
allows the transmission of data over a single pair of sub-standard CAT3 and
other telephone cabling to achieve substantially longer distances. As a
media and protocol converter, the HDMCII VDSL2 LAN Extender Module
(Extended Temp) includes the ability to transfer data both symmetrically and
asymmetrically to meet the customer's needs. In either mode, the VDSL2
port automatically adjusts to an operating point that maximizes the Full-
Duplex bandwidth capability of the line for true plug-and-play operation.
Two HDMCII VDSL2 LAN Extender Module (Extended Temp) media
converters are configured as pairs for each link. One is configured as a Host
(Central Office (CO)) HDMCII VDSL2 LAN Extender Module (Extended
Temp) and is typically deployed at the CO close to network management
systems. The other is configured as a Remote (Customer Premise (CPE)
HDMCII VDSL2 LAN Extender Module (Extended Temp) and is deployed at
the CPE. Full SNMP remote line management is provided through a Black
Box managed chassis, providing remote notification of line fault conditions.
HDMCII VDSL2 LAN Extender Module (Extended Temp) includes:
• One VDSL port with an RJ-11 connector (VDSL)
• One 10/100BaseT Ethernet port with an RJ-45 connector (DATA Port)
