Paradyne Understanding DSLAM Configuration for Routed and Bridged PDUs

Configuring the DSL Router

Routed vs. Bridged PDUs

The DSL router supports both the VNET model and the 1483 Routed model (derived from RFC 1483) for the transportation of PDUs (Protocol Data Units) from the DSL router to the router in the core network. When operating in Standard mode, the DSL router supports both routed and bridged PDUs. When operating in VNET mode, the DSL router supports bridged PDUs only.

NOTE:

Standard mode vs. VNET mode is configured on the DSL card at the

DSLAM/GranDSLAM chassis.

Both ends of the network (e.g., the DSL router and the DSL line card or the core router) must be configured to operate the same way (i.e., routed or bridged).

If Using This Network Model . . .	Then These DSL Cards Can Be Used . . .
1483 Routed or Bridged	Model 8303 24-port IDSL
(Standard Mode)	Model 8344 24-port SDSL
	Model 8374 12-port RADSL
1483 Bridged (VNET Mode)	Models 8303/8304 24-port IDSL
	Models 8343/8344 24-port SDSL
	Models 8373/8374 12-port RADSL
	Model 8510 12-port RADSL

The following diagram illustrates the 1483 Routed model (Standard mode) in the network.
