Chapter 1 Introduction Micronet SP3501AM / SP3501AS delivers cost-effective and highperformance broadband access to multiunit building environments, such as enterprise, campus, hospital, hotel, and telecom. With QAM-based 4-band VDSL technology, the VDSL solution dramatically extends Ethernet and supports 5M/15M/25Mbps symmetrical bandwidth over existing telephonegrade wiring up to 1.9/1.3/0.8KM. 1.

Chapter 2 Installation 2.1 Hardware Installation This section describes how to install the Modem and establish network connections. Users may install the Modem on any level surface. However, please take note of the following minimum site requirements. 2.
y 24-26 Gauge phone wiring VDSL Port (RJ-11) y Do not recommend 28 or y 15M/15M: 1.3km y 25M/M: 800m above Gauge 2.4 y y y y 2.5 y 5M/5M: 1.9km Connecting the Modem The Modem provides a single Ethernet port, which support connection through Ethernet operation. Network devices attached to the Ethernet port must support autonegotiation, 10Base-T or 100Base-TX. Otherwise, the network device must always operate at half duplex.
y y y y y y The Modem’s RJ-11 ports are easy-to-use and do not require installation of additional wiring. Every RJ-11 modular phone jack in the home can become a port on the LAN. Networking devices can be installed on a single telephone wire that can span within 1.9km or 800m (depend on speed) between the two farthest points. SP3501AM/S Modem has embedded Splitter between every VDSL side (Line) and POTS (Phone) side.

Chapter 4 Speed Configuration 4.1 Fixed/Auto Speed Function SP3501AM/S is a 4-band VDSL solution which supports auto and manual speed function and real plug & play. It can support 5M/15M/25M symmetrical data service depend on installation environment. If the cable length is unsure, then auto selection of the data speed at the default setting is recommended. Power must be unplug before changing of data speed, then power on and wait for VDSL to link again at the correct data speed function.
Table shows the summary of DIP switch configuration. DIP Switch Configuration Note: 1. Don’t switch on or off all pins as it will make the VDSL modem functionless. 2. Before selecting the data speed, the power must be turned off for safety purposes. 4.2 y y y Speed mode limitation 5M/5M mode within 1.9km (6333ft) 15M/15M mode within 1.
Chapter 5 Appendix 5.1 Cable Requirements A CAT 3, 4 or 5 UTP (unshielded twisted pair) cable is typically used to connect the Ethernet device to the Modem. A 10Base-T cable often consists of four pairs of wires, two of which are used for transmission. The connector at the end of the 10Base-T cable is referred to as an RJ-45 connector and it consists of eight pins. The Ethernet standard uses pins 1, 2, 3 and 6 for data transmission purposes.
it consists of six pins. POTS (plain old telephone services) use pins 3 and 4 for voice transmission. A telephone cable is shown below. The A and B connectors on the rear of the Modem are RJ-11 connectors. These connectors are wired identically. The RJ-11 connectors have six positions, two of which are wired .The Modem uses the center two pins and the pin out assignment for these connectors is presented below.

5.3 Troubleshooting y Symptom: Power indictor does not light up (Green). ¾ Causes: Defective external power supply. ¾ Solution: Check the power plug by attaching with a functioning one. Check the power cord with other devices. If both tests fail, have the power supply replaced by qualified distributor. y Symptom: Link indicator does not light up (Green). ¾ Causes: Network interface, network cable or switch port may be faulty. ¾ Solution: 1. Power off and reconnect the VDSL modem. 2.
y 5.4 Symptom: S0 bus from an NTBA - data works, but ISDN telephone does not. ¾ Solution: Connect according to the following chart for connecting CO and CPE with NTBA. Other Issues Power and Cooling Problems If the POWER indicator does not turn on when the power cord is plugged in, users may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section.
Transmission Mode The default method of selecting the transmission mode for RJ-45 port is 10/100 Mbps and for RJ-11 port is 5/15/25Mbps. Therefore, if the link signal is disrupted (e.g., by unplugging the network cable and plugging it back in again, or by resetting the power), the port will try to establish communications with the attached device via auto-negotiation. If auto-negotiation fails, then communications are set to half duplex by default.
