Can telecom broadband access the Internet without cats and only through switches?

There is no cat in the school Internet, the cat you are talking about is the modem, (you can now temporarily understand that the school's broadband has been unified modem and demodulation,) in fact, our actual simple network cable, (that is, the kind of cable with 8 copper wires in your dormitory) its theoretical maximum transmission distance is 100 meters, and from the telecommunications company's computer room to your home is undoubtedly more than 100 meters, in order to solve this problem, That's why there is a modem (cat),It's to increase the transmission distance.,But it also reduces the transmission rate.,The theoretical maximum value of ADSL is 8M.。。

Hello, for sure: Yes.

The bandwidth of the switch equipment is basically fiber broadband, and some devices already have the functions of cats and routers.

The switch is connected to your computer's line, which is the ordinary Category 5 line (the network cable of the WAN port), you only need to dial in the computer, if the switch has been set up to go directly to the Internet, you can also do not need to dial.

According to your description: the school of telecommunications does not need cats that can be connected directly to the Internet with a switch. The switch only plays the role of a shunt.

The switch under the optical modem cannot access the Internet is caused by the wrong setting, and the solution is as follows:

1. Open the desktop Internet Explorer, enter enter, and enter the routing login interface.

2. After logging in, various setting options will appear.

3. In the status, you can see whether the China Unicom network you are connected to is registered and you can access the Internet normally.

4. Network-broadband configuration-broadband Internet account setting; Enter your online account and password here.

5. Network - WLAN configuration - basic settings; The name of the SSID, here is the wireless name used, you can change it to your favorite name.

6. Network - WLAN configuration - security settings; WPA pre-shared key, set the Wi-Fi password.

1) Check to make sure that the network topology is connected correctly and the device indicators are normal.

2) Check whether the computer network parameters are correct, and make sure that the computer is directly connected to the router and can access the Internet: this can eliminate the restriction of the router on the computer's Internet access.

3) Try to log in to the router management interface and check whether the management address of the switch conflicts with the router gateway.

4) Check whether the browser is set up with LAN**, try to ping the gateway and the external domain name, if not, continue to check.

If these are all right, then you can locate the problem at the PC and the switch, which can be located from the following steps:

5) Check whether the PC connection port on the switch can communicate with the router connection port, and exclude the switch setting port learning, port and MAC address binding, VLAN (whether the port is in the same VLAN as the router cascade port), ACL settings and other restrictions.

6) Check whether there is ARP spoofing in the intranet, do a good job of two-way binding between the computer and the router IP and MAC, 7) If none of the above is set, the device reset is used as a fool switch, if you can't access the Internet, it is likely that there is a problem with the switch hardware, contact the office or dealer for detection.

That is the line problem, find the operator to solve. The optical modem cannot be shut down, and the old switch optical fiber is easy to break.

What you call the optical modem: 1 is to determine whether the ONU optical terminal or the optical transceiver; 2.The broadband access mode is PPPOE, static IP or LAN LAN.

ONU is a PON terminal device, under normal circumstances, it is no problem to correctly access the switch to access the Internet and divide multiple computers at the same time, and the operator will not object, and will also do one number in the PPPoE account processing to achieve multiple simultaneous dial-up Internet access on one line; If it is a static IP address, it needs to be processed in routing mode and connected to the Internet through the switch sub-platform.

Telecom broadband services often require the use of a cat (CPE device) to connect to convert a fiber optic or ** line signal into a data signal that can be understood by a computer. The cat acts as a bridge between the telecom provider's network and the user's touch device (such as computer, mobile phone, etc.).

So, in general, if you use telecom broadband services, you still need to use a cat to achieve a network connection. If you don't want to use cats anymore, you can check with your telecom provider or network service provider to see if there are any options for their network access. Different regions and providers may have different options and solutions.
