PPP Protocol

 The Point-to-Point Protocol is designed for simple links which transport packets between two peers. These links provide full-duplex simultaneous bi-directional operation, PPP is comprised of three main components:

1. A method for encapsulating multiprotocol datagram. 2. A Link Control Protocol (LCP) for establishing, configuring, and testing the data-link connection. 3. A family of Network Control Protocols (NCPs) for establishing and configuring different networklayer protocols.

Link Installation and Setup

© 2007, ZTE Corporation. All rights reserved.

Link installation and setup  A: ODU installation – initial setup ( This procedure will describe an ODU to be mounted directly on antenna.) 1.Using ½” open /close wrench , attach the antenna mount to the pole in a general direction using any kind of azimuth device, compass, etc. 2. Secure the antenna to the antenna mount (about 1/4 of a turn) and secure the bolts that hold the antenna. 3. Attach the ODU to the antenna and secure the 4 clips that hold the ODU. When the polarization is vertical, the N-type connector should be at 7 o‟clock. 4. Connect the RG-8 cable, coming from the ODU, to the N-type connector and secure it by hand. 5. Connect a DVM to the BNC socket on the ODU. Set the DVM to DC volts to a range between 2-20 Volts (measurement will be 0-3 V).

© 2007, ZTE Corporation. All rights reserved.

Link installation and setup  B: IDU installation – initial setup 1. Connect the Coax cable (RG-8 coming from the ODU) to Coaxial N-Type female connector on the IDU. 2. Connect the IDU to a power source (22-60V DC). 3. Verify the polarity of the power cable. Polarity is especially important when IDU is installed on a rack mount (19” rack). 4. Turn on the main power switch or power breaker to supply DC to the IDU (-40 ~ -58V DC). 5. Set the initial parameters according to your system (Frequency, Link Capacity and Tx Power). 6. Check the Web-CIT display parameters. 7. An RSL value of NA, means there is no signal being received. 8. Check for a reasonable RSL value (before antenna alignment). 9. Please refer to Doc “ZXMW PR10 V4 Radio Microwave System Operation Manual”.

© 2007, ZTE Corporation. All rights reserved.

Link installation and setup  C: Final adjustment 1. The final adjustment is done, always on both sides of the link, at the antenna. It has to be done one by one and not simultaneously. 2. Using the DVM and the fine tilt adjustment of the antenna mount, adjust the pitch and direction of the antenna to get maximum received signal. 3. The average signal strength should be, in good weather, above 2 V DC reading on the DVM, but also according to the path calculation. 4. The voltage is positive (+) and increases with the signal strength (the better the signal –the more voltage). ***The best results are when both sides have the same RSL***. 5. After getting the best results on both side, secure the antenna mount, close and secure the „test‟ BNC connector cap.

Link installation and setup (1+0)  D: ODU installation – initial setup (This procedure will describe an ODU to be mounted separately from the antenna using a wave guide to connect to the antenna). 1. Same as before, attach the antenna mount to the pole in the right general direction. 2. Attach the ODU with a special \ separate mount to the pole. 3. Connect a wave guide between the ODU and the antenna. 4. Please verify the direction of the wave guide according to the antenna and the ODU (vertical or horizontal). 5. Make sure the O-ring is in it‟s place and firmly tight the wave guide screws. 6. Follow the procedure (from step A4 and on) continue with the ODU and IDU installation and final adjustment.
