What does provisioning a cable modem mean?
What does provisioning a cable modem mean?
Provisioning is the reseting of the default configuration for the ISP’s service. Typically for cable providers, this includes recording of one’s cable modem’s MAC or hardware address and copying a json or other configuration file to the cable modem that connects your location to their service.
What is a good dBmV for cable modem?
Ideal levels are approximately 40 to 50 dBmV for single channels, 37 to 48 dBmV each for 2 to 4 channels.
What is a good SNR for cable modem?
30 dB
The downstream SNR tells how much noise is on the cable. Again, for the cable modem to work within the specification, the SNR needs to be at least 23.5dB; a desirable ratio is 30 dB or higher.
What frequency do cable modems use?
In the U.S. cable modems transmit upstream between 5 and 40 MHz and receive downstream between 88 and 860 MHz, although downstream video signals begin around 52 MHz. The term split plan refers to a location in the spectrum where the upstream frequencies and downstream frequencies meet.
What are the 3 types of provisioning?
3) In a traditional telecommunications environment, there are three separate types of provisioning: circuit provisioning, service provisioning, and switch provisioning.
What is Docsis provisioning?
DOCSIS Device Provisioning is a provisioning solution to manage the end-to-end fulfillment of Broadband and Multimedia Services via Cable Modems and PacketCable™ E-MTAs.
What is a good signal to noise ratio for internet?
Signal to Noise Ratio In general, you should have a minimum of +25dBm signal-to-noise ratio. Lower values than +25dBm result in poor performance and speeds.
What is a good SNR level?
Generally, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications. Learn more about Signal-to-Noise Ratio.
How can I improve my cable modem SNR?
Tips to improve your SNR
- 1) WIRE QUALITY – This was THE number one pain in the neck for us.
- 2) KINKS – The minimum bending radius on your cable wires in the house should be about 4″.
- 3) TIGHT CONNECTIONS – All cable connections THROUGHOUT the home should be tight.
What frequency does Docsis 3.0 use?
DOCSIS 3.0 used frequency band 5 MHz to 65 MHz for upstream and 85 MHz to 1002MHz for downstream, whereas DOCSIS 3.1 allocates 5 MHz to 204 MHz for upstream and 252 MHz to 1788MHz for downstream traffic.
What frequency does Docsis 3.1 use?
The DOCSIS 3.1 specification requires cable modems to cover the frequency range of 258 MHz to 1218 MHz for the downstream as well as to receive two 192 MHz channels in parallel. Support to 1794 MHz is optional. The upstream lies in the lower frequency range and extends to a maximum of 204 MHz.
What does device provisioned mean?
Provisioning is the process of setting up a device to be managed via policies by an enterprise . During the process a device installs Android Device Policy, which is used to receive and enforce policies . If provisioning is successful, the API creates a devices object, binding the device to an enterprise.
What is the purpose of provisioning?
Provisioning is the process of setting up IT infrastructure. It can also refer to the steps required to manage access to data and resources, and make them available to users and systems. Provisioning is not the same thing as configuration, but they are both steps in the deployment process.
What is a good signal to noise ratio for audio?
It is generally considered that a good signal to noise ratio is 60 dB or more for a phono turntable, 90 dB or more for an amplifier or CD player, 100 dB or more for a preamp.
How can I improve my Wi-Fi signal to noise ratio?
Once you see the list of WiFi signals, you can do a few things to increase the SNR ratio:
- Remove Extra WiFi networks. This is especially true if this is a business environment.
- Check for “Noisy” devices. Take a look at the devices around the WiFi router.
- Turn off unneeded signals.
Is higher SNR better or worse?
A signal-to-noise ratio over 0 dB indicates that the signal level is greater than the noise level. The higher the ratio, the better the signal quality.
What is a good SNR for audio?
15 dB to 25 dB: is typically considered the minimally acceptable level to establish poor connectivity. 25 dB to 40 dB: is deemed to be good. 41 dB or higher: is considered to be excellent.
