7.14 Alarm Profile Screen
Click Basic Setting and then xDSL Profiles Setup in the navigation panel and
then Alarm
Profile to open the following screen.
Alarm profiles define ADSL port alarm thresholds. The MSAP2000 AAMS
sends an alarm trap and generates a syslog entry when the thresholds of
the alarm profile are exceeded.
Use the top part of the screen (with the Add and Cancel buttons) to add or edit
alarm profiles. The rest of the screen displays the configured alarm profiles.
VC Profile (continued)
DESCRIPTION
When editing a profile, this is the name of this profile. When adding a profile,
type a name for the profile. You can use up to 31 ASCII characters; spaces are
not allowed.
Select the encapsulation type (LLC or VC) for this port.
Select CBR (constant bit rate) to specify fixed (always-on) bandwidth for voice
or data traffic.
Select UBR (unspecified bit rate) for applications that are non-time sensitive,
such as e-mail.
Select VBR (real time variable bit rate) or NRT-VBR (non real time variable
bit rate) for bursty traffic and bandwidth sharing with other applications.
Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak
Cell Rate (PCR). This is the maximum rate at which the sender can send cells.
PCR applies with all of the ATM traffic classes. Type the PCR here.
Cell Delay Variation Tolerance (CDVT) is the accepted tolerance of the
difference between a cell's transfer delay and the expected transfer delay.
CDVT applies with all of the ATM traffic classes. Type the CDVT here.
The Sustained Cell Rate (SCR) sets the average cell rate (long-term) that can
be transmitted. Type the SCR, which must be less than the PCR. SCR applies
with the VBR traffic classes.
Burst Tolerance (BT) sets a maximum number of cells that the port is
guaranteed to handle without any discards. Type the BT here. BT applies with
the VBR traffic classes.
Click Add to save your changes to the MSAP2000 AAMS's volatile memory.
The MSAP2000 AAMS loses these changes if it is turned off or loses power, so
use the Config Save link on the navigation panel to save your changes to the
non-volatile memory when you are done configuring.
Click Cancel to start configuring the screen again.
