    Troubleshooting Payload Loopback The Payload Loopback (PLB) loops the information received on the Network or DSX-1 interface back to the network after it has passed through the receive and transmit framing section of the device. Use PLB for determining whether the problem is with the T1 facility or in the circuitry of the remote device.

  • Page 207: Repeater Loopback

    Repeater Loopback The Repeater Loopback (RLB) loops the information to be sent over the Network or DSX-1 interface back to the device. The RLB loops the entire data stream, which includes data on the interface, as well as the synchronous data ports. Use RLB to ensure that all of the data is correct up to the point where it is sent out over the interface.

  • Page 208: Remote Loopbacks

    Troubleshooting Remote Loopbacks The remote loopback up codes (which put a remote device in loopback mode) and down codes (which take a remote device out of loopback mode) are in-band codes that allow remote control of a device. Network loopbacks are defined in AT&T TR 62411. The LLB up code invokes a line loopback in the remote unit while the LLB down code terminates the line loopback in the remote unit.

    IP Addressing Selecting an IP Addressing Scheme You can select from many IP addressing schemes to provide SNMP NMS, Telnet, or FTP connectivity. When selecting a scheme, keep the following in mind: Because connection to remote devices is through different interfaces (for EDL), it may be necessary to assign IP addresses and subnet masks to each EDL individually.
  • Page 246 IP Addressing For a fractional T1 network when a data port is not configured (in the case of voice only), a single DDL can be used to connect to a remote site. NOTE: When dealing with IP addressing, your Information Systems (IS) department needs to be involved since they typically dictate the IP addressing scheme used in an organization.
