1. GENERAL

This document is an installation and maintenance practice for the ADTRAN Total Access

SHDSL T1/E1 Line Terminating Unit (LTU). Figure 1 illustrates the SHDSL T1/E1 LTU front panel, P/N 1182210L1.

Revision History

This is the initial issue of this practice. Future changes to this documentation will be explained in this subsection.

2. DESCRIPTION

The SHDSL T1/E1 LTU was designed for use in the Total Access 3000 chassis. The Total Access SHDSL T1/E1 LTU provides an interface between the SHDSL network and the Central Office data network. The SHDSL T1/E1 LTU receives a G.703 signal from the network and transmits an SHDSL signal to the customer. The G.703 and SHDSL signals are transmitted/received via the Total Access 3000 chassis backplane connectors. The SHDSL T1/E1 LTU supports loop rates from 192 kbps to 2.048 Mbps.

Figure 1. SHDSL T1/E1 LTU Front Panel

The module is 100 percent compliant with the ITU recommendation (G.991.2) for SHDSL transmission, ensuring spectral compatibility and interoperability.

Features

The basic features of the SHDSL T1/E1 LTU, P/N 1182210L1, include the following:

• Responds to an Embedded Operations Channel (EOC) inventory response message

• Provides both transmit and receive clocking

• Provides a user selectable service state option

• Operates in T1 mode with a data rate of 200 kbps to

1.544 Mbps and E1 mode with a data rate of 192 kbps to 2.048 Mbps

• Non-volatile memory configuration

Trademarks: Any brand names and product names included in this document are

trademarks, registered tra demarks, or trade names of their respective holders.

• Factory default restoration via VT100 menu screens or SNMP commands

• Firmware upgrade using YModem or TFTP connection

• Receives remote NTU’s firmware upgrades via YModem or TFTP connection

• Automatically updates the Circuit ID

• Automatically updates the date and time registers

• Password protected

See Figure 2 for a typical configuration setup.

Connections

The SHDSL T1/E1 LTU inserts into any access module slot (1 through 28) of a Total Access 3000 chassis. Power and alarm signals are provided to the module through the backplane of the chassis.

The G.703 and SHDSL signals are transmitted/received via the 64-pin backplane amphenol connectors. The G.703 signal is transmitted to the network side via “Pair 8,” and the G.703 signal is received from the network side via connector “Pair 7.” The SHDSL signal is transmitted to and from the customer side via connector “Pair 2.”

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may cause undesired operation.

Changes or modifications not expressly approved by ADTRAN could void the user’s authority to operate this equipment.

• SHDSL T1/E1 LTU Installation and Maintenance Practice

CAUTION

Electronic modules can be damaged by ESD. When handling modules, wear an antistatic discharge wrist strap to prevent damage to electronic components. Place modules in antistatic packing material when transporting or storing. When working on modules, always place them on an approved antistatic mat that is electrically grounded.

Instructions for Installing the Module

The SHDSL T1/E1 LTU inserts into any access module slot (1 through 28) of a Total Access 3000 chassis. To install the SHDSL T1/E1 LTU, perform the following steps:

1. If present, remove the Access Module Blank (P/N 1181953L1) from the appropriate access module slot of the Total Access 3000 chassis.

2. Hold the unit by the front panel while supporting the bottom side with the ejector latch at the bottom, and the latch opened to engage the chassis edge when it is plugged in.

3. Align the module edges to fit in the lower and upper guide grooves for the designated slot.

4. Slide the module into the access module slot while pressing equally on the top and bottom of the front panel until the module is firmly positioned against the backplane of the chassis.

5. Lock the module in place by pushing in on the locking lever located on the lower left-hand side of the module.

The SHDSL T1/E1 LTU initializes and goes operational upon insertion into an active Total Access 3000 chassis. Initialization is indicated by the front panel LEDs.

LED Indicators

The front panel of the SHDSL T1/E1 LTU has five LED status indicators. Table 2 lists the LED descriptions.

4. PROVISIONING

All provisioning will be handled through the SCU communication link, either through the menu access or SNMP. There are no onboard DIP switches or jumpers. The unit will retain provisioning data in a nonvolatile memory device in case of a loss of power to the module.

NOTE

To ensure proper display background, select VT100 terminal emulation under

Settings

Total Access 3000 system management and provisioning is facilitated by a series of intuitive menus that are accessible on a computer screen. Connecting either a VT100 terminal or a PC emulating a VT100 terminal to the craft interface on the SCU front panel allows access to the menus and management features of the Total Access 3000.

The front craft access port for the Total Access 3000 system is located on the front panel of the SCU and is a DB-9 connector. Access can also be made to the Total Access 3000 chassis from the backplane through the port labeled

ADMIN (J31). It is a DB-25 connector, and

is located on the upper right corner of the backplane.

NOTE

Connecting to the Total Access 3000 chassis from the front craft port on the SCU requires a straight serial data cable. Connection to the Total Access 3000 chassis via the rear connector on the backplane requires the use of a null modem cable, because that port is configured for a modem and expects to see DCE equipment.

Password and User ID

Password protection is factory enabled. If password protection is enabled, the SCU will display the logon screen, and a valid account name and password are required to access menus. The factory default account names and default passwords (both are case sensitive) are displayed in Ta b le 3.

NOTE

When the LTU is in T1 mode, all related E1 options will be non-applicable. A non-applicable option setting is still changeable, but will not take affect until the option become applicable.

5. OPERATION

Test Capabilities

The Total Access SHDSL T1/E1 LTU has the following test capabilities:

• Self diagnostics

• Local loopbacks

• EOC initiated remote loopbacks

• Internal bit error rate tester (BERT)

Customer Port

The SHDSL T1/E1 LTU operates in either E1 mode or T1 mode.

E1 Mode

In E1 mode the port features are as follows:

• Carries information at the rate of 2.048 Mbps

• Uses CCS framed format with or without CRC-4

• Operates in either Alternate Mark Inversion (AMI) or High-Density Bipolar 3 (HDB3) line code

• Provides programmable timeslot idle pattern

In T1 mode the port features are as follows:

Self Diagnostics

The Total Access SHDSL T1/E1 LTU performs self diagnostic tests of its Read Only Memory (ROM), Random Access Memory (RAM), LEDs, and nonvolatile configuration setting upon power-up.

Local and Remote Loopbacks

For troubleshooting purposes, the SHDSL T1/E1 LTU provides three types of loopback tests.

1. Dual sided

2. Network

3. Customer

BERT

The SHDSL T1/E1 LTU provides an internal bit error rate tester (BERT) for the injection and observation of random bit sequence to and from the SHDSL.

• Carries information at the rate of 1.544 Mbps

• Uses Superframe Format (SF) or Extended Superframe Format (ESF)

• Operates in either Alternate Mark Inversion (AMI) or Bipolar w/8-Zero Substitution (B8ZS) line code
