Anleitung Zusammenfassung
MENU ITEMS ACCESSIBLE VIA THE SCU Local or remote craft port access to the Total Access 3000 HTU-C can be provisioned and tested through 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 Maintenance Practice (P/N 61181017L1-5) for additional information. 3. Hold the HTU-C by the front panel while supporting the bottom edge of the module with the ejector 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 top and bottom of the module (to the right of the ejector latches) to ensure that the module is firmly seated against the chassis backplane connector. Secure the HTU-C in place by rotating the ejector latch into the locked position. After installation is complete, the HTU-C performs a series of initialization and self-tests. Once the series of self-tests are completed, the front panel LEDs reflect the true state of the hardware. FRONT PANEL LEDS *61181107L1-22A* Connect a terminal emulator via the RS-232 (DB-9) connector on the faceplate of the SCU. The Label Status Description DSL1/ terminal must be VT100 or compatible and defaulted to 9600 bps, 8 bit, no parity, 1 stop bit. At DSL2 Off No synchronization of HTU-C and HTU-R on either loop the 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 ACCESS Green Good signal quality (4 to 9) on Loops 1 and 2 Yellow Signal quality marginal (1 to 3) on Loops 1 and 2 MODULES from the Total Access Menu, and then select the corresponding slot number. Red Signal quality poor (0) on Loops 1 and 2 • Flashing Error detected at HTU-C or HTU-R. The color of the LED, when NOTE: When using a PC with terminal software, disable any power saving programs. flashing, indicates loop signal quality. DSX/DS1 BANTAM JACKS Off Network-side DSX-1 signal not detected or of a format that does notmatch provisioning of HDSL circuit Green Network-side DSX-1 signal is present and synchronized with the HTU-C’s interface EQ This jack provides an intrusive test access point to the data stream as follows: . Green Flashing Bipolar Violation (BVPV), frame bit error (SF mode), or CRC error (ESF mode) detected at DSX-1 signal ¦ Equipment Jack = To Customer ALM ¦ TX: Replaces the data stream being transmitted to the customer (HDSL Loops) Off No alarm condition detected Yellow Remote alarm condition (HTU-C) detected ¦ RX: Accesses the data stream being received from the customer (HDSL Loops) Red Alarm condition detected either locally (HTU-C), or locally and remotely (HTU-C and HTU-R) ¦ Equipment jack = To Network ¦ TX: Replaces the data being transmitted to the Central Office ESF/SF Off Unit is receiving Unframed data ¦ RX: Access the data being received from the Central Office Green Unit is receiving SF data When the HTU-C is in MUX mode, the EQ jack can be configured for “To Network” or “To Yellow Unit is receiving ESF data B8ZS/AMI Green Unit is receiving AMI coding Customer” (default setting) direction via the Test screen. In DSX mode, this option is not available, and the EQ jack configuration will be “Fixed to Customer.” Yellow Unit is receiving B8ZS coding MON LBK Off Unit is not in loopback or armed state This jack provides nonintrusive tap to monitor characteristics of the DSX signal as follows: Yellow Local (HTU-C) loopback is active to the network ¦ TX: Monitors signal being transmitted to the customer (HDSL Loops) . Yellow Flashing Loopback arming sequence has been detected; unit is armed (ready forloopback) but not in loopback ¦ RX: Accesses the data being received from the customer (HDSL Loops) HDSL DEPLOYMENT GUIDE INSTALLATION AND TURN-UP The HDSL system is designed to provide DS1-based service over loops as follows: After unpacking the unit, inspect it for damage. If damage is noted, file a claim with the carrier ¦ Cable pairs must be non-loaded and then contact ADTRAN. For more information, refer to the warranty. ¦ No single bridged tap > 2 kft (0.61 meters) NOTE: This unit can be provisioned via the RS-232 port or remotely via inband codes. ¦ Impulse noises < 50 dB as measured using a 50 kB filter ¦ Wideband noise < 31 dBrn as measured using a 50 kB filter To avoid confusion with the access module and common module slots, the access module slots start with the fourth slot from the left on the shelf and are numbered “1” ¦ Pulse attenuation (LOSS on HDSL current system status screen) < 30 dB through “28” for the Total Access 3000, and “1” through “22” for the Total Access¦ Total bridged tap < 2.5 kft (0.76 meters) 3010 on the underlying silk-screen.
