Backhaul Link Configuration
B2CC011AB or B2CC043AA. MP-to-MP links allow you to create a full
mesh topology with up to eight BelAir nodes forming a cluster. Typically, a
mesh cluster contains up to seven BelAir50C nodes and a mesh portal that
can be any BelAir node. The mesh portal connects the cluster to the rest of
the network.
A BelAir50C mesh portal uses its Ethernet LPM connection to route traffic
to the rest of the network.
A BelAir50S mesh portal uses its DOCSIS module connection to route
traffic to the rest of the network.
A BelAir200, BelAir100, BelAir100C or BelAir100S mesh portal can use a
variety of ways to route traffic to the rest of the network depending on how
it is equipped:
—It can use a 5 GHz P-to-P, point-to-multipoint (P-to-MP), or MP-to-MP
backhaul link.
—It can use an Ethernet or DOCIS connection.
• 5 GHz multipoint-to-multipoint (MP-to-MP)—To create these types of links,
the BelAir node must contain a radio with part number B2CC033AA.

• 5 GHz point-to-multipoint (P-to-MP)—To create these types of links, the
BelAir node must contain a radio with part number B2CC033AA. P-to-MP
links allow you to create a star topology with one base station in the middle
connecting up to eight subscriber stations. Typically, P-to-MP links are used
to connect several mesh portals, and their clusters, to the rest of the
network.
Use the
/system/show phyinv
command to display the radio’s part number and
determine the type of radio you have.
