Each 6 x T1 NIC is used at the Sector Terminal to allow the interconnectivity of up to six full duplex T1 circuits. Each T1 port at the Sector Terminal is mapped and routed to a T1 port at a Remote Terminal. All data bits from the Sector Terminal are transported to the Remote Terminals - the transport is clear channel. Therefore, the port supports any type of T1 framing transparently.

A I F't E D m m, 3.2.5.2 Hot Plug-In Impact on Power Supply in addition, each signal circuit card power input includes a reverse blocking diode along with bulk filtering components and a fuse on each supply voltage. If a circuit card fails with a short to ground on one of the power supplies, its fuse will open and allow the rest to recover and reset. The reverse blocking diodes prowde protection from momentary power supply drops while “hot plugging” new circuit cards into the backplane, They will not protect the system from momentary disruption in the case of a power supply fault to ground that results in an open fuse. 3.3 Hub lF Combiner , The Hub IF Combiner is necessary to combine multiple Sector Terminal signals and to route them to a single Outdoor Unit (ODU). This unit is capable of combining up to four Sector Terminal signals. Sector Terminal signals include Transmit IF and Receive lF signals along with carrying | telemetry information. After these signals enter the HUB lF Combiner they are coupled together with a high stability frequency oscillator and 48 Vdc power supply. The high stability frequency I oscillator operates as a system reference for the ODU and its control circuitry. The 48 Vdc voltage is the supply voltage for the ODU. The Sector Terminal IF signals, the reference signals, the telemetry information and the 48 Vdc are all distributed to the ODU by a single cable. I On the back panel of the Hub IF Combiner is a switch that enables the user to select whether the unit is operating Link A or Link B. On the front panel a LED will be illuminated to identify which configuration has been selected, The HUB lF Combiner is powered by AC (refer to Figure 3-7), or DC (refer to Figure 3-8) if the I unit was ordered with the optional DC configuration.

Flam iDU Figure 3—9 - Hub IF Combiner Block Diagram 3.4 Sector Terminal Outdoor Unit (ODU) . The Sector Terminal Outdoor Unit (ODU) is a single integrated enclosure containing an RF components mounted directly to a dual tensed—horn antenna. Antennas have azimuth beamwidth ' angles of 15“, 22.5“, 45° or 90“. Each Outdoor Unit (ODU) is a self contained radio transmitter weighting approximately 132 pounds (6 Kg) attaching directly to an antenna by flexible waveguide to a Sector Terminal antenna. The ODU's are designed to provide frequency diversity, and installed to transmit on either horizontal or vertical polarity. The ODU transmits modulated RF signals to the Remote Terminals and receives RF signals from the Remote Terminals via line-of—sight wireless communication links. Due to rain attenuation considerations operating at 38 GHZ, both the Sector Terminal and the Remote Terminals receive and transmit on the vertical polarization. For operating frequencies of 24 and 26 GHz, orthogonal polarized antenna feeds are used. Based on the operating RF frequency in use. ODUs are available to operate in the 10 GHz, 24 GHz, 26 GHz, 28 GHz, 31 GHz and 38 GHz bands. 68135 Tel~LInk Point-To-Multlpolnt, Rev. A 3-13 p > E D m January 1999 Figure 3-10 illustrates the RF/Antenna configuration for the Sector Terminal Outdoor Unit. The packaging includes the following components: - ODU Enclosure 0 RF Electronics ' ODU Controller Card responsible for controlling and monitoring ODU functions and for interfacing With the DU The ODU is frequency agile so that the same ODU can typically be used throughout the entire allocated frequency band. Subsequently, this reduces sparing levels. The ODU meets all National Electrical Code requirements pertaining to lightning and power transients and meets or exceeds FCC and ETSl regulations pertaining to conducted and radiated Electromagnetic Emissions. The ODU is sealed against the environment and is capable of functioning in ambient temperatures ranging from -40°C to +60°Q with up to 100% relative humidity. The ODU can survive steady state winds of 40 m/s with gusts to 55 m/s (89 mph/123 mph).

The Controller also monitors cable length once a second, and mutes the transmitter if a cable [5 not detected. The controller monitors antenna alignment if that function is enabled via the Local 3-15 65135 Tel-Link PDinl-To-Multipolnt, Rev. A p } E D m Januaryisss Site Manager (LSM). It also monitors and controls transmitter power if enabled configuration parameters are stored in on-board NVRAM. 3.4.1 TX IF Module The TXIF Module up-converts the modulated VHF signal received from the IDU to a C or E Band signal used to drive the Microwave Module. An internal AGC loop corrects for power variations related to coaxtal cable length between the IDU and ODU, and provides an analog signal to the Controller Module for slope correction. Two voltage-controlled attenuators under Controller Module direction sets the drive power to the Microwave Module to establish the overall ODU transmitter power, 3.4.2 RX IF Module The RXIF Module is a dual conversion system that down-converts the C or E Band signal received from the Microwave Module into an UHF signal passed to the lDU through the coaxial cable. In addition, the RXIF Module provides gain to amplify signals over a wide dynamic range guaranteeing a constant signal level is fed through the coaxial cable connecting the ODU to the IDU. An internal AGC maintains a constant signal level and generates an analog Received Signal Strength Indicator (RSSI) signal passed to the Controller Module. This signal level is also available on a Bayonet Nut Connector (BNC) connector for antenna pointing. 3.4.3 Controller PCB The ODU Controller monitors several ODU PMP link variables and conditions; and either transmits these to the IDU or internally adjusts levels within the ODU as appropriate. Communication with the IDU is accomplished by multiplexing and transmitting the signals through the coaxial cable connecting the two units. One major function of the Controller is to monitor and adjust transmitting power; ensuring adequate signal strength is achieved. The Controller will not adjust to unnecessarily high levels that increase the potential for interference with other PMP stations. 3.4.4 Signal Flow-Transmit Direction The transmit IF signal from the lDU arrives at the ODU Motherboard where it is extracted by the multiplexer and routed to the TX IF Module. Simultaneously, the reference signal and telemetry are extracted and routed to the VCXO and Controller Modules respectively. The IF signal is up-converted and filtered by the TX IF Module, and routed to the Microwave Module where it is further up~converted to the output frequency, amplified and filtered. Transmit power control is applied to the process at the output of the TX IF Module. Sector ODU's route the Signal via flexible waveguide to the transmit horn of the sector antenna for broadcasting. 3.4.5 Signal Flow-Receive Direction Signal routing in the receive direction is nearly the reverse of the Signal Flow-Transmit Direction. Received signals in Sector units are passed from the horn antenna to the Microwave Module through flextble waveguide. At the Microwave Module signals are amplified by the Low Noise Amplifier (LNA) and down-converted to the first receive IF, and then sent to the RX IF Module. The first IF is determined by the frequency programmed into the TX IF Module, plus or minus the duplex frequency (depending on whether the unit is set to transmit either high or low band). At the RXIF Module, the receive IF is further down-converted, filtered, amplified and passed to the Motherboard Module, after A60 is applied, and then multiplexed and fed into the cable connecting the ODU and IDU.

For 24-26 GHZ, two horns are used for transmit and receive functions. At 38 GHz, a single horn antenna is used. Specific antennae are used for horizontal or vertical polarizations and for azimuth beamwidths of 15°, 22.5“, 45° or 90”, The elevation beamwidth is typically 6“. The antennae are mounted onto a rectangular mounting plate with mounting hinges used to install on a pole One of the hinges allows for elevation adjustment. . Feed .

The DU and ODU contain “N" type female connectors for interconnection of the coaxial cable. For increased EMC performance P-COM recommends the use of Times—Microwave LMR400, double screened, coaxial cable. Other coaxial cables with equivalent performance characteristics of the LMR~400, shown below in Table 3-3, may be used. LMR-400 may be used in continuous lengths up to 1000 feet.
