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. ALplus2/ALCPLUS2 19

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 passaband 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,
ALplus2/ALCPLUS2
21
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.
•
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 is a big advantage for traffic but less link budget margin at 4QAM.

25
Peak 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

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-3 / VC-4 POH (with E3 and E4) ALplus2/ALCPLUS2
38
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 µs delay or anticipation) and the update is every 4 frames.

TAG composition
1 VLAN TAG
ALplus2/ALCPLUS2
58
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
ALplus2/ALCPLUS2
59
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! ALplus2/ALCPLUS2 60
VLAN VLAN can be used to route packets through local and remote switch. If VLAN are not used, “Lan per port” assignment is used port by port
Disable 802.1q: no Tag filter, “LAN per port” rules
Fallback: if input is tagged, Virtual LAN map rules will be followed; if input tag is not present in the map or input is untagged, Lan per port rules will be followed
Secure: if input is tagged, Virtual LAN map rules will be followed; if input tag is not present in the map or input is untagged, packets will be dropped ALplus2/ALCPLUS2
