Field Name Description
ATM path. This setting works with the VCI. Each individual DSL circuit must have a unique
VPI/VCI combination. String limits are:
0
-
255
.
VCI Enter a Virtual Channel Identifier. A VCI is a 16-bit identifier that has a unique channel.
Options are:
32
-
65535
.
Select DSL
Latency
Select the level of DSL latency. Options are:
l Path0 Fast: No error correction and can provide lower latency on error free lines.
l Path1 Interleaved: Error checking that provides error free data which increases
latency.
l Path0&1 Both: Fast & Interleaved.
Select Link Type Select the linking protocol.
EoA
is the most popular with
PPPoA
a close second (used with
many legacy ISPs). Options are:
l EoA: Ethernet over ATM.
l PPPoA: Point-to-Point Protocol over ATM.
l IPoA: Internet Protocol over ATM.
Encapsulation
Mode
Select whether multiple protocols or only one protocol is carried per PVC (Permanent Vir-
tual Circuit). Options are:
l LLC/ENCAPSULATION: (Available when PPPoA is selected as the Link Type) Logical
Link Control (LLC) encapsulation protocols used with multiple PVCs.
l LLC/SNAP-BRIDGING: (Available when EoA is selected as the Link Type) LLC used to
carry multiple protocols in a single PVC.
l LLC/SNAP-ROUTING: (Available when IPoA is selected as the Link Type) LLC used to
carry one protocol per PVC.
l VC/MUX: Virtual Circuit Multiplexer creates a virtual connection used to carry one
protocol per PVC.
Service Category Select the bit rate protocol. Options are:
l UBR without PCR: Unspecified Bit Rate with no Peak Cell Rate, flow control or time
synchronization between the traffic source and destination. Commonly used with
applications that can tolerate data / packet loss.
l UBR with PCR: Same as above but with a Peak Cell Rate.
l CBR: Constant Bit Rate relies on timing synchronization to make the network traffic
predictable. Used commonly in Video and Audio traffic network applications.
l NON Realtime VBR: Non Realtime Variable Bit Rate used for connections that trans-
port traffic at a Variable Rate. This category requires a guaranteed bandwidth and
latency. It does not rely on timing synchronization between the destination and
source.
l Realtime VBR: Realtime Variable Bit Rate. Same as the above option but relies on tim-
ing and synchronization between the destination and source. This category is com-
monly used in networks with compressed video traffic.
Minimum Cell
Rate
Minimum allowable rate (cells per second) at which cells can be sent on a ATM network. For
no shaping, enter
-1
