ACM setting Radio capacity: Ethernet Permanent TDM (high priority E1) Extra TDM (low priority E1)

ACM enable: bandwidth and reference modulation (its mask can not be exceeded by any ACM profile)

ACM disable: bandwidth and used modulation

Downshift (from 256QAM to 4QAM): the modulation complexity and the radio capacity decrease. Upshift (from 4QAM to 256QAM): the modulation complexity and the radio capacity increase. For each modulation profile the number of extra TDM (and then the Ethernet bitrate) can be set. ALCplus2 35

37

Adaptive Code Modulation

1/2

ACM profiles In ALplus2/ALCplus2 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 These profiles operate in an RF channel with the following   4QAM bandwidth:   8 PSK  7 MHz   16 QAM  14 MHz   32 QAM ODU pass band filters   64QAM  28 MHz   128QAM  56 MHz   256 QAM

ACM switching The usage of the previous modulation profiles in a fixed channel bandwidth results in a variable capacity. The criteria defining the necessity of an ACM switching, upshift or downshift, is the Rx S/N ratio. 

 Upshift – When there is an increase of received S/N, within the same Channel Spacing, the modulation complexity is increased in the direction from 4QAM strong to 256QAM increasing the spectral efficiency



 Downshift – When there is a decrease of received S/N, within the same Channel Spacing, the modulation is reduced in the direction from 256QAM to 4QAM strong reducing the spectral efficiency,

ALCplus2

38

Adaptive Code Modulation

2/2

ACM setting  • •  • •

The ACM can vary modulation profiles between two extremes defined by the operator through software configuration: Upper Modulation and Lower Modulation.  Upper Modulation – When propagation into the given radio channel is in the better condition (high Rx S/N), the radio link is working at the maximum throughput defined at Upper Modulation: the highest modulation profile that ACM can employ  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

Tx Power mode Tx power mode can be set as Constant Peak or Constant Average (constant bolometer measurement).  •



Constant Peak – Tx power is at maximum at 4QAM and at 256QAM is reduced (typical 4.5 dB) so the RF Tx amplifier can operate in better linear conditions





Constant Average – Tx power is the same at any modulation (…is the Upper Mod Tx power)

The Tx Power mode is set depending on the modulation license of the user With Constant Average Tx power (Tx Power Constant Peak Mode = Disable), the Tx power at 4QAM and any other modulation is the same, so if Upper Modulation is 256QAM the output power at any modulation is the same of 256QAM which is 4.5 dB less than 4QAM. The result is that enabling 256QAM gives a big advantage for traffic but less link budget margin at 4QAM.

Average In Average the Max Pout is the Max Pout of the upper mod (23dBm @ 256 QAM) and is the same at any profile

ALCplus2

41

Peak and 4QAM as ref. mod. With Peak mode enabled and 4 QAM as reference modulation, the max Pout is the max Pout of the radio at any modulation

ALCplus2

42

Peak request and 256QAM as ref. mod. With Peak mode enabled and 256 QAM as reference modulation, the max Pout is the Pout that makes the transmitted spectrum not going out from the mask relevant to reference modulation. If reference modulation is not the one that allows the max Pout of the radio, the Tx power mode comes back to Average. Every time the reference modulation is higher than the lower modulation…the power mode becomes Average

Path overhead

The Virtual Container is made up by path overhead and relevant container: VC = POH + C VC path overhead allows BER extimations, alarm and trouble information, multiplation indication. Depending on C, 2 different POH exist:

VC-11 / VC-12 POH (with A1 and E1)

VC-3 / VC-4 POH (with E3 and E4) ALCplus2

53

AUOH Administrative unit overhead Compensation of variation of payload bit rate (with respect to nominal one) is obteined using stuffing. In AUOH there are 6 bytes for justification signal and other 6 bytes (3 in SOH and other 3 adiacent in the same line of the payload) used for stuffing in order to adjust the position of VC first byte: Adjustment, if necessary, concerns 3 bytes more or less (154 s delay or anticipation) and the update is every 4 frames.

TAG composition

ALCplus2

72

IEEE 802.1Q VLANs VLANs in two different ways: - Based on Port, VLAN related to a local port attribute - Based on IEEE 802.1Q TAG , VLAN is defined by the VID (VLan Identifier) TAG content.

Switching between ports is based on VLAN membership defined into Vlan configuration table.

Lan1 and Port1 are members of Vlan 303

ALCplus2

73

IEEE 802.1Q VLANs • Break a LAN into a few smaller LANs and prevent data to flow between the sub-LANs • Micro segment the LAN with scalability • Distribute traffic load • Better control of broadcast messages • VLAN: a field starting with other 4 Bytes starting with the 2 Bytes 8100 – the packet size from 1518 Bytes arrives to 1522! • VLAN with double TAG: a new field with other 4 Bytes starting with the 2 Bytes 9100 (see Ethernet Switch) – Remember to increase packet size! ALCplus2

74

VLAN VLAN can be used to route packets through local and remote switch.

If VLAN are not used, “Port Based VLAN” assignment is used port by port ( Port Based VLAN is the old LAN per port )

Disable 802.1q: no Tag filter, “Port Based VLAN”

will be followed

Fallback: if input is tagged, Virtual LAN table will be followed; if input tag is not present in the map or input is untagged, Port Based VLAN will be followed

Secure: if input is tagged, Virtual LAN table will be followed; if input tag is not present in the map or input is untagged, packets will be dropped ALCplus2

Priority

802.1p Priority management can be defined port by port:

3 bits8 levels

in this example, despite general rules, LAN1 does not consider priority!

Priority queues are set for all the ports

IpTOS 6 bits64 levels ALCplus2

81

Quality of Service  Better service to selected network traffic  Different service classes based on the identity of the customer or the type of application  Different service levels or to ensure service quality for timecritical traffic such as voice or video.  IEEE 802.1p QoS (Layer 2- Quality of Service): 3 bit of the TAG.  IP-V4 ToS (Layer 3- Type of Service): 6 bit of the TOS (D.S.C.P.)  QoS at level 2, at level 3 or at both ALCplus2

Spanning tree edge/no edge

Each port must be assigned to Bridge1 or Bridge2, every equipment crossed by a packet increases of 1 sec the max age of the packet

The Spanning Tree Protocol (STP) is a link layer protocol that ensures a loop-free topology for any bridged LAN.

MAC address & priority Standard STP or rapid RSTP STP params

ALCplus2

86

STP parameters • Hello time: from 2 to 10 sec, is the period between two BPDU packets Forward Delay: the time for a status change (blocking learning, learningforwarding, forwardingblocking). In this way the time requested from blocking to forwarding is twice the Forward Delay (2 status changes) •

• Max Age: If the incoming packet has a max age bigger than the one here defined, the packet is dropped

ALCplus2

87

RSTP parameters • Hello time: from 1 to 10 sec, is the period between two BPDU packets •

Forward Delay: the time for a status change (blocking learning, learningforwarding, forwardingblocking). In RSTP the time requested from blocking to forwarding between two RSTP ports is the

hallo time (RAPID!) instead if the other port is not RSTP, again the time is twice the Forward Delay (2 status changes) • Max Age: If the incoming packet has a max age bigger than the one here defined, the packet is dropped ALCplus2

Configure a new IDU with the SD After the substitution of an IDU, the SD memory of the old IDU can download configuration (“data”) and firmware (“SW”) on the new one automatically as soon as its controller points out a mismatch between the serial number (of the old IDU) stored in the SD and the serial number of the new IDU. After there will be a restart.

To prepare the SD memory to be a “back-up”, in the WEBLCT: 1. Insert an empty SD in the IDU and after run WEBLCT 2. Create a Boot SD …it takes about 10 minutes 3. Enable Automatic Restore (All) Evenctual new setting after this point are included in the back-up The status of the SD will show: Automatic data restore from SD..……..Enabled Automatic SW download from SD……Enabled ALCplus2

ACL – Access Control List A “white list” of IP addresses that can access the LOCAL IDU In order to avoid to be cut out from the IDU: 1) Configure the list 2) Enable the list An empty list, enabled, means: no one can enter! In any case the access to IDU through LCT port (the USB one) is allowed.

Synchronization: Mismatch and Rescue

Config. Mismatch and “5 minutes Rescue” are enabled ALCplus2

104

Configuration Mismatch alarm Every time one of the equip of the hop has a mismatch due to a new setting…the configuration is not applied until the remote is not configured in the same way. Parameters checked through this function are: 1. Traffic division (TDM against Ethernet) 2. Extra TDM setting 3. ACM on/off 4. Reference modulation with ACM off Parameters not checked: Reference modulation with ACM on 5. Extra TDM priority order Channel spacing RF frequency Peak/Average Tx power Link ID ALCplus2

105

Rescue status During the line-up, if the remote, already configured, is not visible both terminals enter in Rescue status: 4QAM and 0 TDM with Rescue alarm ON. After 5 minutes if the remote remains unreachable, they turn back to use the traffic configuration of the line up.

Line trunk (802.3 ad-LAG) Up to 4 Ethernet lines can be grouped to increase capacity (4 different groups are available) in the same IDU Conditions: 1. Same speed 2. Full duplex

Trunk x

Division of Ethernet traffic: XOR between destination MAC and source MAC (hashing)

LAN1

LAN2

LAN3

LAN4

107

Radio trunk (for Ethernet traffic only) Up to 4 different streams can be grouped to increase capacity (1 group only is available). The IDUs must be in the same node. Throughput: • Unicast  < 1Gbit/s bidirectional • Broadcast  < 0.5Gbit/s bidirectional

Division of Ethernet traffic: XOR between destination MAC and source MAC (hashing) ALCplus2

108

ELP A level 2 protection of ethernet lines (2 or more lines in different groups) in the same IDU or in the same node: the switch is performed when a LAN port LOS (on local side) is noticed. When this LOS is over a second switch is not performed. ELP equipment  Prot 1 and 2 ELP nodal  Nodal Prot 1, 2, 3 and 4

112

VLAN 2 is selected

Bind MA

In OAM-FM MA/MEP select the VLAN where to create the MIP and select the command Bind MA. The name of the VLAN is suggested MA name. A MIP is created inside the Ethernet switch.

Now VLAN 2 has a MA and a MIP inside the ALC+2 ALCplus2

113

VLAN 11 is selected

Bind MEP

Select port and direction

•MEP ID is univocal in the VLAN •MA Name is the VLAN label •CCM Interval is the CCM period :1s, 10s, 1m, 10m and LAN4 is the port where CCM messages exit through Now VLAN 11 has a MEP inside the ALC+2, the CCM start from this MEP and go out through LAN4 every 10 seconds

Outside the switch Inside the switch Used port must be NOT “trunked” ALCplus2

114

MEP usage RED: no CCM received from remote MEPs for more than 2.5T , or RMEP not present/crosschecked. Green: received from crosschecked RMEP MEP identity

CCM enabled. The MEP sents CCMs, every T, to its RMEPs to evalutate the status of the VLAN circuit. The CCM can be originated only by a MEP. T = 1s, 10s, 1m, 10m

RMEP: table of Remote MEPs (RMEP) of this local MEP. A RMEP must be crosschecked to be used. Local MEP and its RMEP are in the same VLAN and must have the same CCM period T. A RMEP sends CCMs towards the local MEP and without LBM or LTM does not replies to local MEP.

MEP status: Start - RMEP must be crosschecked Connected – RMEP is working Failed – RMEP is not receiving MAC of remote equip.
