LABEL DESCRIPTION
ATM PVC
The PORT (interface), VPI (Virtual Path Identifier) and VCI (Virtual Channel
Configuration
Identifier) define an ATM PVC (Permanent Virtual Circuit).
VPI Enter the VPI assigned to you for this WAN connection.
VCI Enter the VCI assigned to you for this WAN connection.
Select the check box to use VLAN multiplexing to allow multiple separate
VLAN Mux.
protocols to use the same PVC. Selecting this enables IEEE 802.1q. Separate
VLANs can be used to give different priorities to the traffic from different ports.
802.1Q VLAN ID When you enable VLAN multiplexing, type the VLAN ID that the ZyXEL Device
is to add to the traffic sent through this WAN connection.
Service Category Select UBR (unspecified bit rate) for applications that are non-time sensitive,
such as e-mail. Use it with PCR if you want to specify a maximum rate at which
the sender can send cells.
Select CBR (constant bit rate) to specify fixed (always-on) bandwidth for voice
or data traffic.
Select Realtime VBR for bursty traffic connections that require closely
controlled delay and delay variation (like video conferencing).
Use Non Realtime VBR for bursty connections that do not require closely
controlled delay and delay variation (like non-time sensitive data file transfers).
Peak Cell Rate The Peak Cell Rate (PCR) is the maximum rate at which the sender can send
cells. PCR applies with all of the ATM traffic classes. Type a number of (ATM)
cells per second (1~255000).
Sustainable Cell
The Sustained Cell Rate (SCR) sets the average cell rate (long-term) that can be
Rate
transmitted. Type the SCR, which must be less than the PCR. SCR applies with
the VBR traffic classes. Type a number of (ATM) cells per second. The SCR
must be less than the PCR.
