ONFIGURATION
The MICRO TG60 / MAX TG60 has two modes of operation, Terragraph Mode and Point-to-
Point Mode.
When in Terragraph Mode, the MICRO TG60 / MAX TG60 functions as a CPE device (Client
node) providing last-mile, client-side Internet connectivity.
In Terragraph Mode, the MICRO TG60 / MAX TG60 is triggered passively to set up a 60 GHz
link association. The E2E controller (End-to-End controller), which is either embedded in the
BASE TG60 or runs on the Terragraph Network Management System (TG NMS), triggers the
establishment of all links in the defined Terragraph network. The MICRO TG60 listens for the
signal from the E2E controller to set up a link. Thus, users do not have to configure a link on
the MICRO TG60.
After the link between the MICRO TG60 / MAX TG60 and the POP node have been
established, the POP node informs the CN of the network behaviour.
If the POP node is in Terragraph Mode, every node behaves as an IPv6 router, and the
VXLAN between CN and POP is set up automatically. The VXLAN tunnel can forward Layer 2
services (e.g. PPPoE, multicast streaming) over the Terragraph network. On the contrary, if
the POP node is in Bridge Mode, each node behaves as a Layer 2 Bridge.
When the CN is in Point-to-Point mode, it also functions as a Layer 2 bridge. In this mode,
the CN can setup a point-to-point link without the TG NMS or the local controller on the
POP. Point-to-Point Mode supports VLAN transparent and is designed for point-to-point
backhaul links.
Note
: When in the same network as a BASE TG60 (DN), MICRO TG60/MAX TG60 must be in
Terragraph mode.
