Initial Startup and Configuration Disabling AutoRate The AutoRate function is controlled from the Network Interface Options screen and allows you to enable or disable AutoRate. The AutoRate option is only available if the unit is configured as an LTU.
Cross-Connecting Ports 4 Overview Configuration of the cross-connections consists of the following steps: - Determine how the ports will be connected and configured. - On the Network Interface Options screen, enable if necessary the DSL ports that will be in the cross-connection. The ports are enabled by default. - On the DSX-1 or G.703 Interface Options screen, enable the DSX-1 or G.703 ports that will be in the cross-connection. For G.703, specify whether Time Slot 16 is used for signaling (voice mode).
Cross-Connecting Ports Determining the Configuration The Hotwire cross-connect system allows you to connect the DSX-1 or G.703 ports to the DSL ports in a variety of ways: H DS1 Bypass mode – The entire DSX-1 or G.703 interface is connected to the DSL interface. H DS1 Cross-Connect mode – The entire DSX-1 or G.703 interface is connected to the DSL interface through cross-connect circuitry. Ports can be switched through software. H DS0 Cross-Connect mode – Any time slot of any DSX-1 or G.
Cross-Connecting Ports NOTES: Although the example in this chapter shows ports dedicated to voice or data, a port can be configured for both voice and data. In DS0 Cross Connect mode, for G.703 ports using Common Channel Signaling (CCS), you must explicitly configure the cross-connections for Time Slot 16 and related time slots. You may find it useful to diagram your configuration. Appendix E, Cross-Connection Worksheets, contains a skeleton diagram for this purpose.
Cross-Connecting Ports Assigning Time Slots You may find it helpful to map your cross-connection assignments on a worksheet before configuring them in the unit. In the following example, the worksheet for DSX-1 Port 1, odd-numbered time slots from DSL Ports 1 and 2 are assigned to the time slots of DSX-1 Port 1 and configured for voice.
Cross-Connecting Ports To access the Assign Time Slots screen, follow this menu selection sequence: Main Menu → Configuration → Load Configuration From → Cross-Connect → Assign Time Slots When the screen is first displayed, port and time slot assignments are blank. The following example shows the configuration for DSX-1 Port 1, transferred from the worksheet.
Cross-Connecting Ports When the Cross-Connect Mode screen is displayed now, 1,2 appears next to DSX-1 Ports 1 and 2 because time slots associated with the cross-connection have been assigned.
IP Addressing 5 Selecting an IP Addressing Scheme Your IP addressing scheme depends in part whether the management card controlling the chassis is running IP Conservative software. Configurations Not Running IP Conservative Software In a configuration not running IP Conservative software, the NTU’s network interface IP address is assigned through the peer IP address of the LTU’s Network Interface menu.
IP Addressing Review the following information in preparation for selecting an IP addressing scheme. H Any legal host address is allowed for a given subnet. The address choice within the subnet is arbitrary. H A single route to a subnet is all that is needed to reach every device on a subnet. The unit’s routing table supports a maximum of 20 routes. IP Addressing Example The following diagram shows IP addressing in a typical network.

Glossary 511 A random bit test 511 bytes in length. AIS Alarm Indication Signal. A signal transmitted downstream instead of the normal signal to preserve transmission continuity and to indicate to the rest of the network that a fault exists. Also called a Blue Alarm. AMI Alternate Mark Inversion. A line coding technique used to accommodate the ones density requirements of E1 or T1 lines. ATI Asynchronous Terminal Interface.
Glossary CTS Clear To Send. A signal indicating that the device is ready for the DTE to transmit data. Usually occurs in response to Request To Send (RTS). CV Code Violation. Detected when using HDB3 coding format, this is equivalent to a BPV when using AMI coding. DCE Data Communications Equipment. The equipment that provides the functions required to establish, maintain, and end a connection. It also provides the signal conversion required for communication between the DTE and the network.
Glossary factory defaults A predetermined set of configuration options containing the optimum settings for operation on asynchronous dial networks. FAS Frame Alignment Signal. A loss of frame (LOF) error detection. FAW Frame Alignment Word. A loss of synchronization error detection. FCC Federal Communications Commission. The Board of Commissioners that regulates all electrical communications that originate in the United States. FDL Facility Data Link.
Glossary loopback A diagnostic procedure that sends a test message back to its origination point. Used to test various portions of a data link in order to isolate an equipment or data line problem. LOS Loss of Signal. The line condition where there are no pulses. LTU Line Termination Unit. The control unit on the network end of a link. (The NTU is on the customer premises end.) MCC Management Communications Controller. The DSLAM circuit card used to configure and monitor the DSLAM.
Glossary Telnet Virtual terminal protocol in the Internet suite of protocols. Allows the user of one host computer to log into a remote host computer and interact as a normal terminal user for that host. TFTP Trivial File Transfer Protocol. A standard TCP/IP protocol that allows simple file transfer to and from a remote system without directory or file listing. TFTP is used where FTP is not available. transceiver A circuit capable of acting as both a transmitter and a receiver.
