C A U T I O N !SUBJECT TO ELECTROSTATIC DAMAGEOR DECREASE IN RELIABILITY.HANDLING PRECAUTIONS REQUIRED.For more information, refer to the Installation and Maintenance Practice (P/N 61181107L1-5) available online at www.adtran.com.©2007 ADTRAN, Inc.All Rights Reserved.Total Access 3000/3010HTU-CP/N: 1181107L1CLEI: T1I3AAEA_ _*61181107L1-22A*3. Hold the HTU-C by the front panel while supporting the bottom edge of the module with theejector latches opened to engage the chassis edges.4. Align the module edges to fit in the lower and upper guide grooves for the module.5. Slide the HTU-C into the access module slot. Apply simultaneous thumb pressure at the topand bottom of the module (to the right of the ejector latches) to ensure that the module isfirmly seated against the chassis backplane connector. Secure the HTU-C in place by rotatingthe ejector latch into the locked position.After installation is complete, the HTU-C performs a series of initialization and self-tests. Once theseries of self-tests are completed, the front panel LEDs reflect the true state of the hardware.FRONT PANEL LEDSHDSL DEPLOYMENT GUIDEThe HDSL system is designed to provide DS1-based service over loops as follows:♦ Cable pairs must be non-loaded♦ No single bridged tap > 2 kft (0.61 meters)♦ Impulse noises < 50 dB as measured using a 50 kB filter♦ Wideband noise < 31 dBrn as measured using a 50 kB filter♦ Pulse attenuation (LOSS on HDSL current system status screen) < 30 dB♦ Total bridged tap < 2.5 kft (0.76 meters)♦ 196 kHz insertion loss < 35 dB♦ Maximum loop resistance is 800 ohmsOPTION SETTINGSThe table on the following page lists options that are available when configuring the HTU-C.However, some options are pre-set and dependent upon the System Controller Unit (SCU) beingused. Refer the appropriate SCU Installation and Maintenance Practice when setting options.Label Status DescriptionDSL1/DSL2 {zzz5OffGreenYellowRedFlashingNo synchronization of HTU-C and HTU-R on either loopGood signal quality (4 to 9) on Loops 1 and 2Signal quality marginal (1 to 3) on Loops 1 and 2Signal quality poor (0) on Loops 1 and 2Error detected at HTU-C or HTU-R.

The HTU-C works with multiple list versions of the HDSL Unit Remote end(HTU-R) and HDSL Range Extenders (HRE).MENU ITEMS ACCESSIBLE VIA THE SCULocal or remote craft port access to the Total Access 3000 HTU-C can be provisioned and testedthrough the System Controller Unit (SCU). When deployed with SCU 1181015L1 or1181017L1, the HTU-C can be provisioned via the SCU’s faceplate Four Character Display.Refer to the Total Access 3000 System Controller Unit (SCU) Installation and MaintenancePractice (P/N 61181017L1-5) for additional information.Connect a terminal emulator via the RS-232 (DB-9) connector on the faceplate of the SCU. Theterminal must be VT100 or compatible and defaulted to 9600 bps, 8 bit, no parity, 1 stop bit. Atthe LOGON screen, enter the system User Name and Password. Refer to the appropriate SCUJob Aid for the default PASSWORD. Access the desired HRTU-C by selecting the ACCESSMODULES from the Total Access Menu, and then select the corresponding slot number.NOTE: When using a PC with terminal software, disable any power saving programs.BANTAM JACKSEQThis jack provides an intrusive test access point to the data stream as follows:♦ Equipment Jack = To Customer♦ TX: Replaces the data stream being transmitted to the customer (HDSL Loops)♦ RX: Accesses the data stream being received from the customer (HDSL Loops)♦ Equipment jack = To Network♦ TX: Replaces the data being transmitted to the Central Office♦ RX: Access the data being received from the Central OfficeWhen the HTU-C is in MUX mode, the EQ jack can be configured for “To Network” or “ToCustomer” (default setting) direction via the Test screen. In DSX mode, this option is notavailable, and the EQ jack configuration will be “Fixed to Customer.”MONThis jack provides nonintrusive tap to monitor characteristics of the DSX signal as follows:♦ TX: Monitors signal being transmitted to the customer (HDSL Loops)♦ RX: Accesses the data being received from the customer (HDSL Loops)INSTALLATION AND TURN-UPAfter unpacking the unit, inspect it for damage. If damage is noted, file a claim with the carrierand then contact ADTRAN. For more information, refer to the warranty.NOTE: This unit can be provisioned via the RS-232 port or remotely via inband codes.To avoid confusion with the access module and common module slots, the accessmodule slots start with the fourth slot from the left on the shelf and are numbered “1”through “28” for the Total Access 3000, and “1” through “22” for the Total Access3010 on the underlying silk-screen. Attempting to install the HTU-C in any other slotsother than those listed can damage the module, backplane or both.To install the HTU-C, perform the following steps:1. If present, remove the blank panel from the access module slot on the rear of the TotalAccess 3000/3010 chassis that is intended for the HTU-C.2. Pull the ejector latch, located on the bottom of the HTU-C front panel, from the closedpositions.61181107L1-22A0710Total Access 3000/3010HTU-C
