				Chapter 2: Overview   
					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)

				Chapter 3: Configuration   
					3. Configuration   
					HDMCII VDSL2 LAN Extender Module (Extended Temp) includes various   
					user-configurable features. These features are selectable by using DIP   
					Switches and software. The following sections describe the DIP Switches for   
					the Host CO and Remote CPE module configuration.   
					3.1 DIP Switch Settings   
					The DIP Switches allow the user to configure most of the module features   
					before installing the unit. These also enable the Host to Remote   
					management channel used with SNMP management. Refer to the following   
					diagram and setting table for DIP Switch selection information.

					These features are described in more detail in the following sections.   
					3.2 Host CO Module Configuration   
					To allow the HOST (CO) HDMCII VDSL2 LAN Extender Module (Extended   
					Temp) to manage the remotely connected (CPE) HDMCII VDSL2 LAN   
					Extender Module (Extended Temp) unit, set DIP Switch #1 to the OFF   
					position (default setting). This selection can only be performed manually and   
					cannot be overridden by software settings.   
					A Host configured CO HDMCII VDSL2 LAN Extender Module (Extended   
					Temp) must be installed in a managed chassis to allow SNMP management   
					through iView². The High-Density Media Converter System II chassis series,   
					available in 3, 6 and 20 slots with an optional SNMP Management Module, is   
					recommended. Please refer to the section SNMP Management.   
					3.3 Remote CPE Module Configuration   
					To configure a CPE HDMCII VDSL2 LAN Extender Module (Extended Temp)   
					as a Remote CPE, set DIP Switch #1 to the ON position (OFF is the default   
					setting).   
					A Remote CPE configured HDMCII VDSL2 LAN Extender Module (Extended   
					Temp) can be installed in an unmanaged chassis. These chassis can   
					include Density Media Converter System II chassis with the optional SNMP   
					agent management module removed.   
					3.4 DATA Port Features   
					The 10/100BaseT DATA port on the HDMCII VDSL2 LAN Extender Module   
					(Extended Temp) Auto Negotiates for speed and duplex mode. These   
					modules also provide the option of manually setting the speed and duplex   
					mode if the connected devices do not have the ability to Auto Negotiate, or   
					LMC5601C-VDSL2 724-746-5500 | blackbox.com   
					Page 9   
				Chapter 3: Configuration   
					when Auto Negotiation is not desired by configuring using DIP Switches #8   
					and #9.   
					3.5 Auto Negotiation   
					The HDMCII VDSL2 LAN Extender Module (Extended Temp) ships from the   
					factory with Auto Negotiation enabled on the DATA port. In this mode, the   
					DATA port negotiates for speed and duplex (i.e., the module detects 10   
					Mbps Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex or 100 Mbps   
					Half-Duplex with Flow Control). Configure Auto Negotiation on an HDMCII   
					VDSL2 LAN Extender Module (Extended Temp) by adjusting the DIP Switch   
					#5 (for unmanaged modules) or via the management software (for managed   
					modules).   
					3.6 Selective Advertising   
					Selective Advertising (DIP Switch #7), when used in combination with Auto   
					Negotiation, advertises only the configured speed and duplex mode for the   
					DATA port. If Selective Advertising and Auto Negotiation are both switched   
					ON, the DATA port’s speed (10 or 100 Mbps) and Duplex mode (FDX or   
					HDX) are selectively advertised individually per switch setting #5 and #7.   
					NOTE   
					If you require a specific speed and/or duplex mode, Black Box recommends using   
					Selective Advertising rather than Force Mode when connecting the modules to devices   
					that can ONLY Auto Negotiate. Selective Advertising is NOT an option when you   
					disable Auto Negotiation.   
					3.7 SNMP Management   
					Once the DIP Switches have been set on each module to enable one to be a   
					Host and the other a Remote, the Host can be installed in a High-Density   
					Media Converter System II chassis that includes an installed SNMP   
					Management Module. The Host VDSL2 module then manages the Remote   
					VDSL2 module via the SNMP software iView2 .

					724-746-5500 | blackbox.com   
					LMC5601C-VDSL2   
				Chapter 3: Configuration   
					Traps can also be set in the iView2 software. A Trap will be generated on   
					any Loss of Signal (LOS); but more importantly, the end user can set a VDSL   
					Quality Level that will generate a trap if the line fails below the assigned   
					level.   
					3.8 LINK Quality   
					Link Quality is defined by 4 values: 8,4,2,1. The four green LEDs form a   
					binary code indicating the maximum bandwidth the VDSL line can support.   
					The appropriate LED will light once the line quality is dynamically detected.   
					This represents the maximum Downstream data rate (Kbps) the line can   
					support based upon line noise and line length. The Upstream rate will be   
					less based on the Base Plan used.   
					3.9 Forcing Duplex Mode   
					The DATA port can be manually configured on the HDMCII VDSL2 LAN   
					Extender Module (Extended Temp) for Half- or Full-Duplex operation. Before   
					manually setting the duplex mode, disable Auto Negotiation (Set DIP Switch   
					#5 to OFF).   
					• 
					• 
					Full-Duplex for the DATA port is configured by setting DIP Switch #8 to   
					the OFF position (default).   
					Half-Duplex for the DATA port is configured by setting DIP Switch #8 to   
					the ON position.   
					LMC5601C-VDSL2 724-746-5500 | blackbox.com   
					Page 11   
				Chapter 3: Configuration   
					3.10   
					Forcing the Data Port Speed   
					The DATA port can be manually configured on HDMCII VDSL2 LAN   
					Extender Module (Extended Temp) for 10 Mbps or 100 Mbps operation.   
					Before manually setting the speed, disable Auto Negotiation (Set DIP Switch   
					#5 to the OFF position.)   
					• 
					• 
					10 Mbps for the DATA port is configured by setting DIP Switch #9 to the   
					OFF position (default).   
					Configure the DATA port for 100 Mbps operation by setting DIP Switch   
					#9 to the ON position.   
					3.11   
					Flow Control   
					Flow Control is used as back pressure on the 10/100BaseT DATA interface   
					to avoid dropping packets during VDSL link congestion. Full-Duplex Flow   
					Control will be advertised only when the module is set to Full-Duplex Mode.   
					For Full-Duplex Flow Control to operate, the link partner (connected devices)   
					must also support Flow Control. Half-Duplex Flow Control does not   
					advertise but provides a hardware based backpressure on the Ethernet line   
					to limit traffic.   
					Flow Control should be considered whenever the VDSL line provides less   
					bandwidth than the DATA port. If the Ethernet line is attempting to send   
					more data than the VDSL2 line can support, the Overflow (OVF) LED will   
					come ON indicating frames are being discarded due to congestion.   
					Overflow activity will be less if Flow Control is enabled. Flow Control or   
					Pause will limit the number of dropped Ethernet frames by reducing the   
					congestion, therefore minimizing the overflow of the VDSL line.   
					Configure the DATA port on the HDMCII VDSL2 LAN Extender Module   
					(Extended Temp) for Flow Control by setting DIP Switch #6 to the ON   
					position.

				Chapter 4: Install the HDMCII VDSL2 LAN Extender Module   
					(Extended Temp)   
					4. Install the HDMCII VDSL2 LAN Extender Module (Extended Temp)   
					Before installing an HDMCII VDSL2 LAN Extender Module (Extended Temp),   
					set the options using the DIP Switches (refer to the DIP Switch Settings   
					section for more information).   
					Install HDMCII VDSL2 LAN Extender Module (Extended Temp) in any Black   
					Box High-Density Media Converter System II chassis. Each module requires   
					one slot in the chassis; always use HDMCII VDSL2 LAN Extender Module   
					(Extended Temp) in pairs with the Host module at the CO and the Remote   
					module at the CPE.   
					To install a module, remove the blank brackets (if present) covering the slots   
					where you will install the module by removing the screws on the outside   
					edges of the bracket. Slide the module into the chassis, via the card guides,   
					until the module is seated securely in the connector. Secure the module to   
					the chassis by tightening the captive screw. Save any blanks removed   
					during installation for future use.   
					Remote CPE modules can be installed in a managed or unmanaged chassis.   
					Remote CPE modules can only be managed from the connected Host CO   
					HDMCII VDSL2 LAN Extender Module (Extended Temp) installed in a   
					managed chassis. The user should always set remote DIP Switches to   
					provide a base value under VDSL line fault conditions. In addition, some   
					features may not be software configurable on the remote unit. After setting   
					the DIP Switches, install the HDMCII VDSL2 LAN Extender Module   
					(Extended Temp). Once the VDSL line is established, the line can be   
					monitored and configured through the iView2 management software available   
					for download at   
					ftp://ftp.blackbox.com/anonymous/lan/Managed%20Media%20Converters/L   
					MC5200a/.

					The unit will automatically adjust to reach the best bandwidth performance   
					for the physical line it is connected to. The associated LED display will   
					indicate the Bandwidth performance the unit is running at any given time.   
					This is not the bandwidth that is being transmitted but the bandwidth   
					capability of the line. The Bandwidth number is based on "VDSL User   
					Payload" and includes the VDSL Frame overhead. For Band Plan 998, this   
					LED display will indicate the MAX down stream rate to the Remote unit.   
					Band Plan 997 will provide the greatest symmetrical bandwidth the line can   
					support. The end user can also select Band Plan 998 for asymmetric   
					operation, to provide better downstream performance. Either plan will   
					automatically adjust for the greatest bandwidth transport. The HDMCII   
					VDSL2 LAN Extender Module will automatically seek the best operating   
					condition for the physical line it is connected to.   
					NOTE   
					The RANGE is only an approximation based on a typical line in a normal noise   
					environment. Actual distances will vary depending on the condition of the physical   
					line in use.

					When a 10/100BaseT port is lost, the unit sends a fault signal (RAI) to the   
					VDSL line. If the LFPT function is enabled at the Far End VDSL port   
					receiving this fault indication, the far end unit will drop the link on the   
					10/100BaseT port and BLINK the LFPT LED. This function must be enabled   
					at both ends of the VDSL line for this to function in both directions. The   
					LFPT function is only active in one direction at a time and is indicated by the   
					flashing LED. As such, clearing the far end fault may uncover a fault at the

					The most common failure of a VDSL line is its slow degradation over time   
					due to aging of the line or increased line noise as additional service is added   
					to the same Line bundle. To help detect this degradation over time, the unit   
					provides a user-defined Minimum Quality Level. Once this level is reached,   
					the unit will send an SNMP TRAP indication for low line quality. This can be   
					used to provide an advanced notice to the customer of a potential problem   
					BEFORE a loss of service is detected by the customer.

				Chapter 8: Fiber Optic Cleaning Guidelines   
					8. Fiber Optic Cleaning Guidelines   
					Fiber Optic transmitters and receivers are extremely susceptible to   
					contamination by particles of dirt or dust, which can obstruct the optic path   
					and cause performance degradation. Good system performance requires   
					clean optics and connector ferrules.   
					1. Use fiber patch cords (or connectors, if you terminate your own fiber) only   
					from a reputable supplier; low-quality components can cause many hard-to-   
					diagnose problems in an installation.   
					2. Dust caps are installed at Black Box to ensure factory-clean optical devices.   
					These protective caps should not be removed until the moment of connecting   
					the fiber cable to the device. If you need to disconnect the fiber device,   
					reinstall the protective dust caps.   
					3. Store spare caps in a dust-free environment such as a sealed plastic bag or   
					box so that when reinstalled they do not introduce any contamination to the   
					optics.   
					4. If you suspect that the optics have been contaminated, alternate between   
					blasting with clean, dry, compressed air and flushing with methanol to remove   
					particles of dirt.

				Chapter 9: Electrostatic Discharge Precautions   
					9. Electrostatic Discharge Precautions   
					Electrostatic discharge (ESD) can cause damage to any product, add-in   
					modules or stand alone units, containing electronic components. Always   
					observe the following precautions when installing or handling these kinds of   
					products.   
					1. Do not remove unit from its protective packaging until ready to install.   
					2. Wear an ESD wrist grounding strap before handling any module or   
					component. If the wrist strap is not available, maintain grounded contact with   
					the system unit throughout any procedure requiring ESD protection.   
					3. Hold the units by the edges; do not touch the electronic components or gold   
					connectors.   
					4. After removal, always place the boards on a grounded, static-free surface,   
					ESD pad or in a proper ESD bag. Do not slide the modules or stand alone   
					units over any surface.   
					WARNING! Integrated circuits and fiber optic components   
					are extremely susceptible to electrostatic discharge damage.   
					Do not handle these components directly unless you are a   
					qualified service technician and use tools and techniques that   
					conform to accepted industry practices.
