Rj45 loopback plug pinout3/2/2024 ![]() Off otherwiseīlinks when the serial port receives or transmits data On the Cisco 633 an RJ-11 connector provides an xDSL connection to external media through a standard RJ-11 6-pin modular jack. If the timeout is set, the Cisco 627 WAN LNK LED turns off after that time period whether or not it is idle. If the WAN LNK LED turns off after the Cisco 627 has been transferring data, the Cisco 627 or the Cisco 6100/6200 has the SESSION timeout set. No available ATU-Cs with which the Cisco 627 trains up. The ADSL line is not connected to the Cisco 627. There are several reasons why this occurs: If the WAN LNK LED blinks continuously, the Cisco 627 never trains with the Cisco 6100/6200 DSLAM. The ADSL line port on a Cisco 627 uses a standard RJ-11 6-pin modular jack. ![]() If the timeout is set, the Cisco 626 WAN LNK LED turns off after that time period whether or not it is idle. If the WAN LNK LED turns off after the Cisco 626 has been transferring data, the Cisco 626 or the 6100/6200 has the SESSION timeout set. No available ATU-Cs with which the Cisco 626 trains up. The ADSL line is not connected to the Cisco 626. If the WAN LNK LED blinks continuously, the Cisco 626 never trains with the Cisco 6100/6200 digital subscriber line access multiplexer (DSLAM). This indicates that the ADSL connection sequence has begun. During subsequent requests for data, the WAN LNK light starts to blink. For example, this condition occurs when there is no data traffic across the WAN LNK for a period of time. Note: In certain circumstances in which the Cisco 626 operates correctly, the WAN LNK light appears off when the PWR/ALARM light is on. If the LED still appears red, call your service representative. Turn off the power and then turn it on again. If the LED is not on, call your service representative. If the light still does not turn on, turn off the power and then turn it on again. If the light does not turn on, check all cabling and connections. If the WAN LNK light does not turn on when you power up the modem: The ADSL port on a Cisco 626 uses an RJ-11 connector. On when the ADSL port transmits or receives data. On when a link is established on the ADSL port. The Asymmetric Digital Subscriber Line (ADSL) port uses an RJ-11 connector.

There are no specific requirements for this document. Note: Not all DSL CPE modem/router products use the same DSL interface port pinouts. If the NID is installed by a Telco, the Telco must verify its functionality. The DSL cable between the Network Interface Device (NID)/wall jack/splitter and the Cisco DSL customer premises equipment (CPE) modem/router is the correct type. ![]() If you experience problems with the DSL connection on these devices, verify these : In this document, pinouts are named "port pinouts." Note: The terms "port pinouts" and "connector pinouts" are used interchangeably. This document describes the port pinouts and LED statuses for specific Cisco digital subscriber line (DSL) devices.
