Multi-Carrier ABC Overview (CLI)
Multi-Carrier Adaptive Bandwidth Control (ABC) enables multiple separate radio carriers to be shared by a single
Ethernet port. This provides an Ethernet link over the radio with the total sum of the capacity of all the radios in
the group, while still behaving as a single Ethernet interface. In Multi-Carrier ABC mode, traffic is dynamically
divided among the carriers, at the Layer 1 level, without requiring Ethernet Link Aggregation.
Load balancing is performed regardless of the number of MAC addresses or the number of traffic flows. During
fading events which cause ACM modulation changes, each carrier fluctuates independently with hitless
switchovers between modulations, increasing capacity over a given bandwidth and maximizing spectrum
utilization. The result is 100% utilization of radio resources in which traffic load is balanced based on instantaneous
radio capacity per carrier.
One Multi-Carrier ABC group that includes both radio interfaces can be configured per unit.
Note
If the modulation of a radio carrier in the Multi-Carrier ABC group drops to Profile 0, that carrier is
removed from the group until modulation returns to Profile 1 or higher.
In this version, one Multi-Carrier ABC group that includes both radio carriers can be configured per
unit. The MRMC scripts for both radio carriers must be identical.
Configuring a Multi-Carrier ABC Group (CLI)
The Multi-Carrier ABC group configuration procedure is different for PTP 820F, on one hand, and PTP 820G, on the
other.
For PTP 820F, Multi-Carrier ABC is configured between the two carriers of the same RFU (RFU-D or RFU-D-HP).
For PTP 820G, Multi-Carrier ABC is configured between different radio interfaces connected to different RFUs.
