9124-A2-GH30-00 June 1999 - Preliminary
Using Multiplexed PVCs
Instead of having one PVC for the router (DLCI 909) and another for the
FrameSaver unit, management of the network can be accomplished using only
the router PVC when the NOC uses a FrameSaver unit, which has its own IP
address, as seen in the illustration below.
Simply create a dedicated PVC between the NOC and the router, then let the
system automatically discover the DLCI and convert it to an EDLCI via its
Auto-Configuration feature (DLCI 909/EDLCI 2). This solution eliminates the need
for two DLCIs per central-site FrameSaver unit-router set. The management PVC
would be shared by both the unit and the router.

Whether automatically discovering or manually configuring DLCIs, a local
management PVC must be created between each FrameSaver unit and its router
if management through a back door is desired. Using private addresses, the
router will not pass the DLCI to the network so the PVC is reserved for
management only.
Management through a back door can be accomplished via a dial line to the
router. Should the network fail, communication with both the router and the
FrameSaver unit would be maintained.
In this case, one PVC is used for both unit and router management.

DLCI 909/EDLCI 2 is used to manage the unit.

DLCI 908 is a static route between the central site and the router for back
door managment of the unit.
