1. About Hotwire 8777 and 8779 TDM SDSL Units1-2 May 2002 8700-A2-GB20-40TDM SDSL FeaturesThe 2-wire Hotwire 8777 or 8779 TDM SDSL Termination Unit is a circuit boardthat is mounted in a Hotwire 8610 or 8810 Digital Subscriber Line AccessMultiplexer (DSLAM), or an 8620 or 8820 GranDSLAM, and used to transportsignals at high speeds over a twisted-pair connection.Hotwire 8777 and 8779 TDM SDSL Termination Units have these standardfeatures: Cross-Connection Capability. Any DSL port and time slot can be connectedto any DTE port and time slot. Embedded Operations Channel (EOC). Provides remote management viaSNMP or Telnet session capability over the DSL network. The bandwidth ofthe EOC is a 4 Kbps dedicated channel for the Model 8777 and 8 Kbps for theModel 8779. Asynchronous Terminal Interface (ATI). Provides a menu-drivenVT100-compatible terminal interface for configuring and managing the unitlocally or remotely by Telnet session. Local Management. Provides local management using the DSLAMmanagement card with a:— Terminal or PC via the Management Serial port of the DSLAM— Network Management System (NMS) via the Management MCC port ofthe DSLAM through the port card’s 10BaseT port Remote Management. Provides remote management:— Out-of-band, using an external modem through the Management Serialport of the DSLAM— Inband using one of the DS0 channels as the management channel totransport SNMP traffic to the MCC card (Model 8779 only).— Via Telnet over the EOC Alarm Indication. Activates front panel LEDs. Diagnostics. Provides the capability to diagnose device and networkproblems and perform tests, including digital loopbacks, pattern tests, andself-test. Device and Test Monitoring. Provides the capability of tracking andevaluating the unit’s operation, including health and status, and error-ratemonitoring.Model . . . Has eight . . .
