Transmission & Minilink TN System BY: Khalil Al-alami

Transmission (TRM) › Transmission is A process where the traffic (voice, Data, video, etc.) transmitted over a medium between source and destination. › Transmission medias: – Wired: › Copper cable. › Optical fiber . – Wireless: › Microwave Radio. › VSAT.

› Transmission in telecom is to transmit the traffic from a site to the Network.

Khalil Al-Alami | 8-May-2017|

PDH › PDH protocol: (plesiochronous digital hierarchy) is a technology used in telecom to transport large quantities of data over digital transport equipment via fiber optics or Microwave Radio. › PDH standards: – E1 (Europe). – T1 (America). – J1 (Japan).

› E1 is the PHD form or standard which is used in Europe. Its used in our country as well. E1 based on that the transmitted frame consisted of 32 time slots. So the E1 capacity is 2.048mbps, so if you have been gotten an E1 cable that’s means you can transmit or receive 2 millions bit during each second. › PDH traffic could be either TDM or packet over PDH. Khalil Al-Alami | 8-May-2017|

Microwave (MW) radio system › What is MW Communications? Is a wireless TRM system that use very short wave length Radio signals. wave length is (0.130cm) so it using very high frequency (300MHz to 300GHz), its similar to radio communications, but MW like visible light, unlike Radio communications its blocked by obstacles, they need a clear path to reach their destination. Mounting Antennas up on a high level like tower offers a clear line-of-sight (LOS) to opposite site, its commonly used for point to point communication. › In other words A microwave link is a communications system that uses a beam of Radio waves in the microwave frequency range to transmit information between two fixed locations on the earth.

Khalil Al-Alami | 8-May-2017|

Page 7

Microwave (MW) communications › A point to point Microwave link: is a link between two sites (say A & B), one site we call it Terminal the direct link between A and B we call it a “hop”, each site consisted of two parts: – – – –

Outdoor Part (OD): which is the Radio Unit (RU). Indoor Part (ID): which is Modem Unit (MU). parabolic Antenna which is the air interface or passive part. Radio or IF cable or feeder. Which connects the ID with OD.

› In some MW systems like Backbone equipment's the RU is located near the ID unit and connected with the Antenna by long wave guide. › In order the radio signal to be transmitted between the two sites: – we need to have a clear path (obstacle free) between these two sites which we call it line-of-sight (LOS) condition which is checked during survey stage. – nearby enough distance to the opposite site as according to the link design.

› Adaptive Modulation: The use of adaptive modulation allows MW system to choose the highest order modulation depending on the current conditions.  Increasing modulation makes the radio more sensitive to rain and multi-path fading but gives higher capacity. › ATPC Mode: ATPC is used to automatically adjust the transmit power in order to maintain the received input level at the far-end terminal at a target value. ATPC compensates for the fading condition. the transmit power can be increased rapidly during fading conditions and allows the transmitter to operate at less than the maximum power during normal path conditions. The low transmit power allows more efficient use of the available spectrum.

Traffic protection: › 1- (1+1 E1 SNCP): is a protection mechanism used for traffic protection on E1 level It is based on the simple principle that one E1 traffic is transmitted on two separate E1 connections. The two E1’s are from the same link or from two links at the same direction like Dual polarization or the comely using is from two different links routed through one ring. › LAG (Ethernet protection): used to backup Ethernet traffic which is coming from two different physical ports at the TN or from two different links usually a part of one ring.

› MSP (1+1 STM1 for SDH): is a protection mechanism used for traffic protection on STM1, between two nodes of SDH traffic. › MSP Example: if we have two copy of one STM1 in Node site and need to implement MSP protection. Khalil Al-Alami | 8-May-2017|

Page 19

Some MW TRM protection Techniques: › In this example I will assume that one STM1 coming from backbone MW Ring and the other coming from the optical Ring and both carrying the same traffic, in case one of them goes down the other still carrying the traffic. MSP Example: LTU 155e/o MSP protection

Antenna Alignment › To have a functioning MW link for the first time you need: › first to have the minimum required ID and OD hardware fully installed and commissioned and configured at both ends and powered up. › Clear hop path (there is LOS). › Alignment: it’s the process of positioning the two facing each other antennas in the point to point MW links to tune the azimuths and tilts until get as best as receive signals at both terminals MMU’s. › Be sure to turn off the ATPC function during the alignment, and the transmitter is on. › If Far-End terminal is off or not transmitting and you receive some RSL that’s means you are facing an signal interference. › If the polarization in the near-end and far-end are not the same then its impossible to achieve the full RSL. (RSL around -65dBm) › If there are some obstacle in hop path this will reduce the max achieved RSL. (Need to check LOS) Khalil Al-Alami | 8-May-2017|

Radio Terminal troubleshooting loops : › IF Loop: In the MMU the traffic signal to be transmitted › is, after being modulated, mixed with the frequency of a local oscillator and looped back for demodulation in the same MMU and this will test MMU functionality. › RF Loop: In the RAU for the transmitted RF signal is looped back to the receiving part of the same RAU. This will test the RAU functionality. › RX loop which mentioned before, the E1s in the traffic connection is looped back to the Radio path. This to verify the communication over the radio path.

ML-TN some Facts › Plug-in units can be inserted while the NE is in operation. This enables adding new Radio Terminals or other plug-in units without disturbing existing traffic. › Plug-in units can be removed from the NE while it is in operation, each plug-in unit has a Board Removal button (BR), pressing this button causes a request for removal to be sent to the control system. › When changing a plug-in unit, the new plug-in unit automatically gets the same configuration as the previous. › The configuration is stored in a non-volatile ROM on the NPU. › ML-TN offers a removable memory module (RMM) which copy all configuration, in case the NPU damages you will put this RMM inside the new NPU and restore the configuration. Khalil Al-Alami | 8-May-2017|

Page 46

› Also the configuration can be backedup and restored using a local or remote FTP server. › When an RAU or MMU is replaced, no new setup has to be done. › Various restarts can be ordered from the management: A cold restart can be initiated for a TN or single plug-in unit. This type of restart is traffic disturbing. A warm restart is only available for the whole TN. This will restart the control system and will not affect the traffic. This is possible due to the separated control and traffic system in the ML TN. › All plug-in units are equipped with temperature sensors. When a plug-in exceed limit Temp thresholds, it will be put in reduced service or out of service by the control system. This is to avoid hardware failures in case of a fan failure. › The plug-in unit is automatically taken into normal operation when temperature is back below the high threshold. Khalil Al-Alami | 8-May-2017|
