Multichannel - Adaptive Bandwidth Control (ABC)
• Multichannel ABC is an effective technology for transporting packets over
multiple dynamic “links”
• Works on layer 1 and is independent of frame types and packet flows
• Automatically scales with available channels/links
• Handles from 2 RF channels to 8 RF channels and from 10 to 400 Mb/s per
carrier (RF channel)
- Max aggregated payload (Layer2) is 1.6 Gb/s
IEEE 802.1 Link Aggregation does not
work if a link is used between two MPLS
switches the Ethernet segment is a
single flow as the MAC address is the
same for all packets and the IP address
is “hidden” behind the MPLS tag

Hybrid radio frame - best of both worlds
• A traditional “packet over TDM” approach
encapsulates packets in the E1/T1 frame
• The Evolution Series uses a Hybrid frame
structure. The frame size is optimized for
maximum capacity in a given RF channel
• The frame might be used for TDM circuits,
Ethernet packets or a combination
• Enables transport of up to 75E1s or
96T1s and scalable Ethernet
• Same efficiency as native framing
• “Native IP” radios are optimized for data
and has no TDM (E1s) capacity
• TDM circuits are handled by circuit
emulation
• Adds significant overhead and delay

Evolution Series - Graceful migration to IP
• Migrating to IP transmission without replacing legacy TDM systems
• Hybrid transmission vs circuit emulation
- Lower overhead - better spectrum utilisation
• QoS enabled infrastructure - enables differentiated services
• Best of both worlds - effective TDM and effective Ethernet solutions
• Synchronous Ethernet (or 2 MHz in/out) timing distribution in Ethernet only
networks
