17.6 Alarm Profile Screen

Alarm profiles define ADSL port alarm thresholds. The IES-1248-51 sends an alarm trap and
generates a syslog entry when the thresholds of the alarm profile are exceeded.
To open this screen, click Basic Setting, xDSL Profiles Setup, Alarm Profile.
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.

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.
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. You can type a number of
(ATM) cells per second in the first field or type a number of kilobytes per second
in the second field to have the system automatically compute the number of
ATM cells per second.
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. You can type a number of (ATM) cells per second in the
first field or type a number of kilobytes per second in the second field to have the
system automatically compute the number of ATM cells per second.
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 IES-1248-51's volatile memory. The IES-
1248-51 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.
