T1/E1 LINK EXTENDERS 2. Installation Because the T1/E1 Extenders require no configuration, they can be installed quickly. Installation consists of the following: • Connect the power plug (refer to section 2.1, “Connecting Power” on page 10). • Connect the line port (refer to section 2.3, “Connecting the Line Port” on page 11) Note See Figure 1 and Figure 2 for the rear-panel connectors locations. • Connect the T1/E1 port (refer to section 2.4, “Connecting the Circuit Interface” on page 11).
T1/E1 LINK EXTENDERS 2.1 Connecting Power CAUTION The external AC adaptor shall be a listed limited power source that incorporates a disconnect device and shall be positioned within easy reach of the operator. Ensure that the AC power cable meets all applicable standards for the country in which it is to be installed, and that it is connected to a wall outlet which has earth ground. Your T1/E1 Extender comes with an external AC adaptor with a detachable power cord.
T1/E1 LINK EXTENDERS 2.3 Connecting the Line Port CAUTION The interconnecting cables shall be acceptable for external use and shall be rated for the proper application with respect to voltage, current, anticipated temperature, flammability, and mechanical serviceability. Follow the steps below to connect the line port: 1. Obtain a single-twisted pair cable with an RJ-45 plug connector at each end. 2. Plug one end of the cable into the RJ-45 socket (labeled Line) on the T1/E1 Extender . 3.
T1/E1 LINK EXTENDERS 3. Operation Once the T1/E1 Extenders are properly installed, they should operate transparently. No user settings required. This section describes reading the LED status monitors. 3.1 Front Panel LED Status Monitors Models MT196A-E1 and MT195A-T1 feature three front-panel LEDs that monitor power, Ethernet signals, and the CopperLink connection. Figure 4 shows the front panel location of each LED. Table 1 describes the LED functions.
