Reboot your modem/router - Sometimes the old "turn it off and on again" approach actually does work! Just wait about five minutes before turning it back on to make sure ...
Damage to the cable requires special skills to repair or total replacement. Specialized equipment can inter-connect two LANs over a single twisted pair of wires, such as the Moxa IEX Series, Cisco LRE (Long Reach Ethernet), Enable-IT Ethernet Extender Experts VDSL2, Patton CopperLink or EtherWAN Ethernet Extenders using VDSL technology ...
RJ11 is commonly used to connect DSL modems to the customer line. [ citation needed ] The conductors other than the two central tip and ring conductors are in practice variously used for a second or third telephone line, a ground for selective ringers , low-voltage power for a dial light, or for anti-tinkle circuitry to prevent pulse dialing ...
The first types of small modular telephone connectors were created by AT&T in the mid-1960s for the plug-in handset and line cords of the Trimline telephone. [1] Driven by demand for multiple sets in residences with various lengths of cords, the Bell System introduced customer-connectable part kits and telephones, sold through PhoneCenter stores in the early 1970s.

In 1988, AT&T released StarLAN 10, named for working at 10 Mbit/s. [11] The StarLAN 10 signaling was used as the basis of 10BASE-T, with the addition of link beat to quickly indicate connection status. [c] Using twisted-pair cabling in a star topology addressed several weaknesses of the previous Ethernet standards:
This helps the telephone company know if trouble is present in the line, the smartjack, or customer equipment. Indicator lights to show configuration, status, and alarms are also common. Smartjacks typically derive their operating power from the telephone line, rather than relying on premises electrical power, although this is not a universal rule.
Data Carrier Detect (DCD) or Carrier Detect (CD) is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a simple "high/low" status bit that is sent from a data communications equipment (DCE) to a data terminal equipment (DTE), i.e., from the modem ...
