Bridge Routing
VPI:
A virtual path is a semi-permanent connection between endpoints in an ATM 
network and may support one or more virtual channels. In Private Virtual 
Circuit (PVC) mode, the Virtual Path Identifier (VPI), which is a header 
subfield, is assigned manually when ADSL Bridge is used. Different VPI 
values allow the endpoints to discriminate between different virtual 
connections between ATM nodes.
The minimum and maximum values of the VPI are 0 and 255, respectively. At 
default, VPI is set to 0.
VCI:
Each connection in an ATM network is characterized by a Virtual Channel 
Identifier (VCI)
. This is a header subfield that is assigned manually when 
ADSL Bridge is used. A VCI has only local significance on the link between 
ATM nodes. When the connection is released, the VCI value on the involved 
links will be released and can be reused by other connections.
The minimum and maximum values of the VCI are 32 and 4095, respectively. 
At default, VCI is set to 0.
PPP User Name:
The name of the Internet account provided by your ISP.
PPP Password:
The password you use to access your ISP account.
OAM F5 Timer:
The Operations and Maintenance (OAM) F5 Timer feature transmits 
loopback cells to the remote peer according to the specified period. Note that 
the local peer will always respond to a loopback cell that is transmitted by the 
remote peer. If the OAM F5 timer is set to 0, then no loopback cell will be sent 
to the remote peer.
