DESCRIPTION

The Total Access 3000/3010 High-bit rate Digital Subscriber Line (HDSL) Transceiver Unit for Central Office (HTU-C, P/N 1181107L1) is used to deploy an HDSL T1 circuit using 4-wire metallic facilities. 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 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 or 1181017L1, 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.

Connect a terminal emulator via the RS-232 (DB-9) connector on the faceplate of the SCU. The terminal must be VT100 or compatible and defaulted to 9600 bps, 8 bit, no parity, 1 stop bit. At the LOGON screen, enter the system User Name and Password. Refer to the appropriate SCU Job Aid for the default PASSWORD. Access the desired HRTU-C by selecting the ACCESS MODULES 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 JACKS

EQ

This jack provides an intrusive test access point to the data stream as follows: Equipment Jack = To Customer

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.

Flashing

Error detected at HTU-C or HTU-R. The color of the LED, when

Network-side DSX-1 signal is present and synchronized with the

 

 

 

HTU-C’s interface

 

 

Green Flashing

Bipolar Violation (BVPV), frame bit error (SF mode), or CRC error

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 Office

When the HTU-C is in MUX mode, the EQ jack can be configured for “To Network” or “To 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.”

INSTALLATION AND TURN-UP

After unpacking the unit, inspect it for damage. If damage is noted, file a claim with the carrier and 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 access module 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 Access 3010 on the underlying silk-screen. Attempting to install the HTU-C in any other slots other 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 Total Access 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 closed positions.

HDSL DEPLOYMENT GUIDE

The 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 ohms

OPTION SETTINGS

The 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) being used. Refer the appropriate SCU Installation and Maintenance Practice when setting options.

For more information, refer to the Installation and Maintenance Practice (P/N 61181107L1-5) available online at www.adtran.com.
