QoS (Quality of Service) are technologies that ensure the transfer of certain
amount of data at a time, ensuring a good quality of service.
In the case of standard Internet traffic, such as browsing websites, emails or
instant messaging, the quality of service defined as BE (Best Effort) is the most
appropriate. BE is one of the four services QoS defined in DOCSIS / EuroDOCSIS, and
is designed to work on a "first come, first served" basis.
To perform the PING test, a PING (Packet Internet Grouper) is sent. It is about
transmitting data packets point to point between PROMAX-27 serving as cable modem
and another remote point access to the network that answer to the transmission. These
PING are a set data packets with a request and response echo. This way it can be
checked the status of the connection with the test point to verify.
From the obtained data it is displayed a BE report, the PLR and latency. The
results shown indicate what problems must be identified and resolved and those ones
that may be caused by problems at headers or IP.
In short, the PING function of the PROMAX-27, performs an exhaustive analysis
of the network based on parameters set by BE, which will ensure the best quality
service. The deep knowledge about network conditions will guide you during installation
and will help you solving problems that may arise.
To access the PING function:
1.- Press key
2.- Press softkey MODEM [F1].
3.- Press softkey IP NETWORK [F1].
4.- The instrument starts the registration process in the CMTS of the NETWORK.
On the display it will appear the word "TUNING" during the process. You must
wait a few minutes until it is registered. If registration process is right, it will
display the word "DONE" on the screen. Failure in registration process will be
displayed as an "ERROR IN REGISTRATION".
5.- Press softkey PING [F4].
