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
