Megabit Modem
300S (MM300S) provides a high-speed data connection over a single-pair copper line to another modem. The modem uses Symmetrical Digital Subscriber Line (SDSL) technology to support data rates from 128 to 2048 kbps. The data rate is manually set, based on the connection distance and line condition.The modem connects through its 10BASE-T port to a PC or Local Area Network (LAN). The SDSL port provides access to the following type of connection: connection to another Megabit Modem 300S, which provides access to a remote PC or small LAN (Figure 1). Figure 1. Megabit Modem 300S Connection
The table below shows the best and worst case reach (based on an industry-standard noise model) on 26 AWG (0.4 mm) and 24 AWG (0.51 mm) wire for each data rate the Megabit Modem 300S supports. The actual reach depends on the condition of the line and the presence of bridge taps, splices, line noise, and so on.

The Megabit Modem 300S provides Media Access Control (MAC) layer bridging of frames received on its LAN and WAN interfaces. It provides transparent address learning—storing up to 8192 MAC addresses—for the LAN interface. Address entries are aged out after 300 seconds. The modem does not support spanning tree; as a result, it cannot be used in parallel with another bridge to provide redundancy.The SDSL connection requires a dedicated single-pair wire to connect the local and remote units. The modem compensates for Tip and Ring reversals; therefore, rewiring the junction box should not be necessary.The MM300S is easy to install: set the transmission rate with a dial on the back panel, connect the cables, and it’s ready to use. The modem may be installed on a desktop or mounted on a wall.


The MM300S allows larger packet sizes to accommodate Virtual Local Area Network (VLAN).Power Supply 50/60 Hz, 120-220 Vac In, +5 Vdc OutConnectorsEthernet Connector RJ-45 connector for 10BASE-T interface, wired as MDI-XSDSL Connector RJ-11 connector for SDSL interfaceDefault SDSL Margin LED Threshold 6 dBPhysicalDepth 5.5 in.
