7.1.2 Baseband processor The baseband Processor (BBP) carries out the following operations: • primary and secondary power supply • line interfaces and protections • baseband circuits and packets processing • I and Q signals generation and sampling • I, Q demodulator • Rx baseband filtering • Actuators and measurement points for TRx unit • FPGA debug connector • FPGA • Controller BBP unit is different depending on the interface type (electrical or optical). 7.1.
With LLF enabled the equipment connected (routers, switches so on) can be notified that radio link is not available and can temporarily re-route the traffic. In same cases, the radio link failure can be unidirectional, for example when the local equipment has an Rx signal failure but the remote Rx signal is OK (i.e. unidirectional radio full due to failure of a transmitter).
7.1.5 Synchronisation unit (SETS) Into ALFOplus a synchronisation circuit, called SETS (Synchronous Equipment Timing Source), gets the synchronisation signal from the following different sources: • LAN1 • LAN2 • radio • Internal source From the synchronization sources the reference clock is chosen on the base of alarm roots (Synch Loss, Synch Drift, Holdover Freerunning), on the base of assigned priority, manual forcing and preferential switch (see Fig.9).
7.1.6 Adaptive code modulation ACM profiles In ALFOplus radio family uses Adaptive Code and Modulation (ACM) in order to employ the correct modulation profile depending on the Rx signal quality. Available ACM profiles are the following: • 4QAM strong • 4QAM • 16QAM strong • 16QAM • 32QAM • 64QAM • 128QAM • 256QAM • 512QAM • 1024QAM.
• Lower modulation - When propagation into the given radio channel is in the worst condition (low Rx S/N), the radio link is working at the minimum throughput, defined at Lower Modulation: the lowest modulation profile that ACM can employ 7.1.7 ATPC and ACM interaction The Automatic Transmission Power Control (ATPC) regulates the RF output power of the local transmitter depending on the value of the RF level at the remote terminal.
7.2 LOOPS To control the equipment correct operation a set of local and remote loops are made available. The commands are forwarded by the WEBLCT program. The available loop facilities are: • Line Loop (Ethernet Port Loop) • Baseband loop PHYSICAL ETHERNET PORT Tx ALFOplus BBP-GE RADIO BASE BAND LOOP LINE LOOP Rx Fig.11 - Available loops 7.
Tab.10 - Logical functions Logical function Description of included functionalities Physical Layer management Management of the phy parameters and characteristics if the physical interfaces. Ingress Filtering Filter/drop frames on the base of specified criteria and rules, ingress port rate limiting, storm control.
• IP: the priority is set based on the DSCP field of the either IPv4 or IPv6 (Native ToS/DSCP) • Default: the priority is set in a static mode and its value is configurable based on the Entering LAN interface. This Default configuration is a “Port Based” Priority with default priority value of 0 (lowest priority). These priority values can be configured by the user within the range from 0 (lowest priority) up to 7 (higher priority).
For example, it is possible to assign specific CIR/EIR policies basing on: • the type of service (e.g, voice, signalling, data, etc..) • the specific operator (e.g. in case the microvawe network is shared between 2 or more operators) • the destination terminal (e.g.
- Ingress port of the packet - C-VID and priority of the packet when received on the ingress port The new TAG is added to the packet as a S-TAG. The Ethertype field of the TAG can be set either to standard values (0x88A8, 0x9100, 0x9200, 0x9300) or to any other custom values. 7.3.5 Congestion avoidance The Congestion Avoidance is a method that permits to discard some frames before congestion occurs.
• Pmax=10 Profile 2: - Smin= 20 - Smax=40 - Pmax=10 These profiles can be set for the Yellow Frames (Y) and Green Frames (G) as well. These values represent: • Smin: represents the threshold after which the switch starts dropping packets • Sman and Pmax: are the thresholds that makes the curve of “Drop Percentage”/”Average Queue Occupation” change. After this point the dropping packets increase rapidly.
Fig.15 Means that the Serving Priority of the frames present in the queues will be: • the packets present in the Queue 7 will be transmitted with a Race 8/35 • the packets present in the Queue 6 will be transmitted with a race 8/35 • ...... • the packets present in the Queue 0 will be transmitted with a rate 1/35. 7.4 ETHERNET FRAME FRAGMENTATION QoS preserve High priority traffic, by giving it precedence during traffic congestions.
Fig.16 - Ethernet frame fragmentation disabled With the fragmentation enabled the time that the packet in higher queues have to wait is smaller. With fragmentation enabled the radio divides the 1024 byte packet into 4 packets of 256 Bytes and the servant can transmit the first frame of 256 Byte in the lower queue and then transmit the high priority traffic, reducing the jitter in the network, see Fig.17. Fig.17 - Ethernet frame fragmentation enabled 7.
When enabled, the user can select which header have to be compressed considering the following maximum limits: • the total header field size cannot exceed 124 bytes • the total header field size after internal coding cannot exceed 118 bytes. the internal coding is required by SIAE switch in order to perform the compression task. In Fig.18 are detailed the different header fields that can be selected with their weight in terms of header field size and header field size after internal coding.
7.6 ETHERNET OAM (OPERATION ADMINISTRATION AND MAINTENANCE) This protocol can be used in any point-to-point Ethernet link. The aim of this protocol is to check and monitor the functionality of the service that the provider guarantees on the network. 7.6.1 Service layer OAM The Service Layer OAM fully monitors a customer End-to-End Ethernet Service. Two main standards cover this topic, the IEEE 802.1ag and ITU-T Y.1731. The IEEE 802.

ified. Two Directions are possible, MEP “ ” and MEP “ ”. With MEP “ ” configured the OAM PDUs are sent from the interface in the direction outside the equipment, i.e. the OAM PDUs are sent from the interface on the cable toward next equipment. With MEP “ ” configured the OAM PDUs are sent from the interface toward the inside of the equipment and will follow the VLAN table previously configured.
In other words, the “RMON Statistics” are the data that are collected and stored in the Network Equipment, while the “RMON History” is an aggregation of the data collected from each network equipment and the database is located in the NMS. 7.8 RMON COUNTERS RMON statistics are composed by counters for each port of the device that are stored in the equipment deployed on field.
• Utilization TX: The best estimate of the mean physical layer network utilization on this interface during this sampling interval, in hundredths of a percent. The percentage is always referred to a 1Gbit/ s port speed. So, it represents the mean TX throughput measured on the port during the sampling period and it is expressed as a percentage of a port speed. All the counters described above are part of the RMON statistics and it is not possible to collect only a subset of them.
7.9.2 Service RMON The Service RMON counters allow the equipment to track the variables listed above depending on the Service (Vlan Tag). This type of RMON can be set only on the Radio interface. Each equipment can be set to collect RMON up to 32 Services (Vlan Tag) and only one Customer Tag. These counters will be available only with the Minimum Polling Policy of 15 min. 7.10 SYNCHRONISM Network Synchronisation is a growing subject related to the network evolution from TDM to Ethernet payload.
Internally to each SIAE equipment the SETS identify the input and output types of interfaces by the following codes: • TE: This code represents an Ethernet interface (LAN) used as input CK • T0: Output interface. This code represents the Internal Clock The purpose of the above list is to list the different acronyms used by the SETS that may be present in the configuration screens. There are some features to be used for maintenance or refined tuning of the clock propagation. Fig.
7.11 SOURCES OF SYNCHRONISM SIAE equipment is able to select among different sources of synchronization. A priority has to be assigned to enable each source, with a value ranging from 1 to 9 included. The priority 1 corresponds to the maximum value, while the priority 9 corresponds to the minimum value. The priority shall be used to select in which order the different synch sources must be used. In case the Priority is set as “Disabled” the correspondent interface is not used as a synchronization source.
7.12 MAB PROTOCOL (MICROWAVE ADAPTIVE BANDWIDTH) Microwave radio transmission capacity depends on radio channel propagation conditions. In case of Ethernet ring, capacity degradation can affect one side of the ring, while the other is still working at nominal capacity. In case of congestion events, Microwave radio prioritizes the Ethernet traffic, by reducing or discarding the lower priority frames.
ing from SIAE equipment and Hello-Packets’s loss (i.e. the high priority traffic is still transported while the Best Effort traffic is cut). For this reason, the ACM functioning in presence of Ethernet ring protection could generate disruptions into services because of the small amount of capacity passing across radio links affected by propagation phenomena. A key point to consider is the duration of an event that can result in a change of modulation: it ranges from few minutes to tens of minutes.
MW Adaptive Bandwidth (MAB) protocol description The general approach to solve this problem will be through the use of a special “Ethernet Operations, Administration and Maintenance” (E-OAM) message, which will be able to report changes in bandwidth availability. Through a combination of the generation and reception of this message and the appropriate configuration of forwarding rules on the Cisco MWR, the ring will be able to modify the traffic profile to take account of the degraded path. An ITU-T Y.
After the Hold-Time expires, the MEP detects the SD defect condition and the Cisco MWR will perform the following actions: • Issue a Syslog message that displays the Nominal Tx BW as well as the Current Tx BW. • Evaluate, based on the degradation in BW, which ERP instances need to be failed over and trigger the failover for these instances.
Fig.26 - Microwave adaptive bandwidth 7.13 FADE MARGIN MEASURE In ALFOplus is available the Fade Margin Measure. The Fade Margin is the difference between the Received Power and the Threshold at a given BER. Once the link is planned, in the Link Budget is present a Fade Margin that has been calculated through mathematical formulas. The Fade Margin depends from the propagation’s parameters and from the presence of interferers.
The maximum range of Fade Margin for ALFOplus is 30 dB. For extra attenuation is required an external attenuator. In case the link budget presents a value of Fade Margin to be measured higher than the actual range it is necessary to apply an “External Attenuator” and insert the correspondent attenuation on input data menu. The Fade Margin Calculation is traffic affecting. Warning: Fade margin measure works by disabling ACM engine on local and remote equipment. 7.
7.15 G.8264 SSM – SYNCHRONISATION STATUS MESSAGE The SSM is a protocol that transmits the quality of the synchronization message throughout the network (G.781). In the synchronization network the transmission of the quality of the clock allows the network to be scalable and to provide redundancy. In case of failure of SIAE equipment or cable, it is helpful to provide redundancy for clock propagation in order to avoid synchronization loops.
b. Radio with quality SSUT (Priority 2) In case the sources have equal quality, the SIAE equipment will switch the source of synchronization with higher priority, in this case (a) the LAN1 with Priority 1 and quality SSUT. However, if a DNU quality would be received on LAN1, the SIAE equipment will switch the synch source to Radio port.
The other configuration present in SIAE equipment that manage the role of the LAN interfaces (Master/ Slave) is present in the main configuration of each LAN interface. Regardless if each LAN interface is set manually as Master/Slave or with autonegotiation, the setting of dynamic or static in the SSM configuration is privileged.
