LTPH-UM-1049-02, Issue 2 Overview

OVERVIEW

The H2TU-C-319 List 4E (H2TU-C) line unit is the Central Office (CO) side of a T1 transmission system. The HiGain HDSL2 product family is fully compliant with the HDSL2 standard ANSI T1.418. Providing full-rate T1 access using a single copper pair, HDSL2 is a cost-effective solution that offers an open architecture. The open architecture inherent in HDSL2 guarantees interoperability allowing simple and economic accommodation of network growth.

HiGain HDSL2 products provide 1.552 Mbps transmission on one unconditioned copper pair over the full Carrier Service Area (CSA) range. The CSA inc ludes loo ps up to 12,000 feet of 24 AWG wire or 9,0 00 feet o f 2 6 AWG wire, including bridged taps.

FEATURES

Features specific to the List 4E family of HDSL2 modules include:

• Report menu option for downloading status and performance monitoring data to a file

• Enhanced loopback commands controlled by the SmartJack Loopback (LPBK) option as follows: – 100 in-band loopdown command – 100000 (1-in-6) in-band loopu p command

• Connection of the HDSL2 span to Loop 2 on pins K and 9 rather than on Loop 1, pins F and 6

• Sources sealing current when connected to an H2TU-R-402 List 5E or higher

Standard features include:

• HDSL2 transmission features – Lightning and power cross-protection on HDSL2 interfaces – Full-duplex HDSL2 transmission on one pair at 1.552 Mbps – Ultra-low wander (Stratum 1 compliant) – Grounded loop detection on High-bit-rate Digital Subscriber Line 2 (HDSL2)

• Front-panel provisioning features – Four character status display – DS1 splitting and bridge access – Status Light Emitting Diodes (LEDs) – RS-232 craft port for connection to a maintenance terminal – MODE and LBK pushbuttons

COMPATIBILITY

The H2TU-C has two unique features, Metallic Test Access and Dual DS1 port options, which are not provided in standard ADC line units with 3192 mechanics. These featu res require additional access pins which are pr ovided by a special card-edge connector, shown in F igure 33 on page 68. Only the HMS-358 set of shelves can accommodate this special connector.

APPLICATIONS

HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital Service (HCDS) over a single copper pair. HiGain HDSL2 systems support a multitude of network connections and system models .

• The service is deployed over one unconditioned, non-loaded copper pair.

• Conventional, inline DS1 repeaters are no longer required.

• Cable pair conditioning, pair separation and bridged tap removal are not r e quir ed.

Each loop has no more than 35 dB of loss at 196 kHz, with driving and terminating impedances of 135 general, HiGain HDSL2 systems:

• Operate effectively in the same cable binder g roup with other HDSL2 lines, HDSL, T1, ADSL, SDSL, POTS, DDS, and other transmission schemes.

• Can be used with customers requiring DS1 service on a temporary or permanent basis.

Ω. In

• Provide a means of quickly deploying service in advance of fiber-optic transmission systems.

Verification with an H2TU-R Remote Unit

If an H2TU-R remote unit has been installed:

1 Verify that the H2TU-C powers up. (The front-panel display illuminates and reports various status messages.) 2 Verify that the H2TU-C attempts to communicate with the remote unit (status LED flashes red). One of the

following occurs:

• If the remote unit is successfully identified and the HDSL2 loop synchronizes, the H2TU-C status LED

lights a steady green. The H2TU-C reports normal margin messages o n the front-panel display.

• If the remote unit is not identified, the H2TU-C reports four-character status messages. The H2TU-C

attempts communication again and reports four-character status messages. The H2TU-C repeats this cycle until a remote unit is detected.

3 Verify that a valid DS1 signal has been applied to the H2TU-C and the H2TU-R.

• If no DS1 signal is being applied to either the H2TU-C or the H2TU-R inputs, then the appropriate DS1

alarms (LLOS or RLOS) display on the front panel and the status LED flashes red.

• If a valid DS1 signal is being supplied to the H2TU-C and H2TU-R, then DS1 alarm indications should

be absent and the status LED should be a steady green.

Provisioning LTPH -UM-1049-02, Issue 2

PROVISIONING

There are two provisioning methods:

• Use the MODE and LBK pushbuttons on the front panel of the H2TU-C to: – Set system options – Reset the H2TU-C to its factory default settings for system options – Display system option settings (scroll mod e) – Select system loopbacks – Select MTA test mode

• Use a maintenance terminal, such as an ASCII terminal or a PC running terminal emulation software,

connected to the H2TU-C craft port or an HMU craft port to access the maintenance screens. Figure 3 on

page 13 shows the maintenance screen. This provides full access to all H2TU-C status, histor y, inventory, and

provisioning screens.

No dip switches or jumpers are required to provision the H2TU-C as it contains a non-volatile RAM (NVRAM) which stores the system option settings. System option settings are retained if shelf power is lost or if the H2TU-C is unplugged.

USING THE MODE AND LBK PUSHBUTTONS

Setting Options through MODE and LBK

To provision the H2TU-C through the MODE and LBK pushbuttons on the front panel: 1 Press the MODE pushbutton for 1 second and then release it. The front panel display alternately shows the

first system parameter and its current setting.

2 Press the LBK pushbutton to step through all possible settings of the selected paramete r. 3 After the desir ed s e ttin g ha s been selected, press the MODE pushbutton. This updates the current displayed

parameter to the selected setting, then advances to the next configurable parameter. After the last parameter has been selected, a CONF NO message appears on the front-panel display.

4 Do one of the following:

• To cancel the session without saving the requested parameter changes, press the MODE pushbutton or

do nothing. After 30 seconds, the display returns to its normal mo de without saving the new changes.

• To accept the requested parameter changes, press the LBK pushbu tton. A CONF YES message displays,

and the display returns to its normal mode after saving the new changes.

LTPH-UM-1049-02, Issue 2 Provisioning

Resetting to Factory Default Values

All user options for the H2TU-C, described in Table 5 on page 18 , can be set to the factory default values using the MODE and LBK pushbuttons. To set the user options to their default values:

1 Press the LBK pushbutton for 6 seconds until the following message appears:

DFLT NO

2 Press the LBK pushbutton until the DFLT NO message is displayed.

The message changes to DFLT YES indicating the factory default values are now in effect and the display returns to the normal mode.

To terminate the DFLT mode without setting the factory default values, do one of the following:

• Press the MODE pushbutton to return to the normal display mode.

• Wait 30 seconds for the unit to return to the normal display mode.

Displaying System Parameter Settings

To scroll through the current settings of all system parameters, press the MODE pushbutton for 3 or more seconds. The H2TU-C displays the following parameters:

• H2TU-C software version number

• H2TU-C list number

• Type of frame pattern received from the DSX-1

• Line code of the signal received from the DSX-1

• All user-configured parameter settings

• Loop attenuation threshold setting

• Margin alarm threshold setting

Disabling an Alarm

System alarms can be disabled by pressing the LBK pushbutton on the H2TU-C front panel. This executes an ACO and returns the H2TU-C to its non-alarm state. For more information, see “Retiring System Alarms” on

page 53.

Loopback Modes

See “Loopback Operation” on page 55 for instructions on using the MODE and LBK pushbuttons to activate loopbacks.

USING A MAINTENANCE TERMINAL

Connecting to a Maintenance Terminal

The craft port on the front panel allows you to connect the H2TU-C to a maintenance terminal (ASCII terminal or PC running a terminal emulation program). Once connected to a maintenance terminal, you can access the maintenance, provisioning, and performance screens.

To connect to a maintenance terminal: 1 Connect a standard 9-pin terminal cable to the RS-232 craft port, as shown in Figure 1 on page 3, on the

front panel.

2 Connect the other end of the cable to the serial port on the maintenance terminal. 3 Start a terminal emulation program such as Procomm that emulates a VT100 terminal. 4 Con fi gur e the main tenan ce ter mi nal to the following communication settings:
