ATM Ping
The loopback cell is a kind of
cell. Among the nodes
of the ATM link, if a loopback cell is detected, the system deter-
mines whether to return the cell according to the segment or end
properties. ATM ping is a method that uses the OAM cells to check
whether the physical links work normally.
In the FSAP 9800 system, the process of implementing ATM ping
by a
port is as follows:
1. FSAP 9800 delivers an ATM loopback cell to the port.
2. After receiving the cell, the modem returns it to FSAP 9800.
3. FSAP 9800 checks whether the loopback is successful ac-
cording to the cell sending and receiving conditions, and thus
checks whether the DSL line works normally.
Environment Monitoring
Environment monitoring includes environment parameter moni-
toring and power monitoring. Environment parameter monitoring
aims to monitor the temperature, humidity, flood, smog, entrance
guard, and distribution frame. Power monitoring aims to monitor
the power supply system.
Environment
Monitoring
System
For hardware, the environment monitoring system consists of an
monitoring plug-in box and
card. For software, the FSAP
9800 integrated
displays and configures various environment
data variables.
Functions
The environment monitoring module performs the following func-
tions:
�
Manages and controls the operation and configuration of the
monitoring card.
�
Checks the parameters reported by the power supply, fan, and
distribution frame.
