-- Trunk/n PathAdmin AtmAccess
-- This subcomponent is optionally added to the PathAdmin 
-- component on ATM hardware. 
-- Without this subcomponent the PathAdmin will transport all Path 
-- Oriented traffic as AAL5 encapsulated cells on the Trunk 
-- AtmAccess localConnection VCC.
-- With this subcomponent added under the PathAdmin the PathAdmin 
-- will operate in one of two modes. These modes are referred to as 
-- mapping and multiplexing and the selection of the mode is done by 
-- setting the PathAdmin AtmAccess mode attribute to either mapping 
-- or multiplexing.
-- When the mode is set to mapping, the PathAdmin will create new 
-- VCCs for each new LCh that it sets up. In mapped mode the CPU 
-- usage is normally 0 for a connection and so the ATM FP can 
-- support a great many more mapped mode connections than it can 
-- multiplexed mode connections. Connections whose 
-- maximumTransmissionUnit is exactly 45 will use the SPO adaption 
-- layer to efficiently fit a single voice frame into a single cell with 
-- minimum overhead. All other connections will use the AAL5 
-- adaption layer protocol.
-- When the mode is set to multiplexing, the PathAdmin will look at 
-- the attribute atmConnection which points to a second provisioned 
-- ATM VCC. The PathAdmin will then multiplex voice frames onto 
-- this second VCC using a proprietary Short Path Oriented adaption 
-- layer which encapsulates one voice frame into one voice cell with 
-- low overhead. The PathAdmin will multiplex all non voice traffic 
-- over the Trunk/n AtmAccess atmConnection VCC using the AAL5 
-- protocol.
