1. GENERAL

This document is an installation and maintenance

practice for the ADTRAN Total Access® SHDSL T1/

E1 Network Terminating Unit (NTU). Figure 1 illus-

trates the SHDSL T1/E1 NTU front panel, P/N

1225236L1.The SHDSL T1/E1 NTU is a network

terminating module using Single-Pair High Speed

Digital Subscriber Line (SHDSL) technology to

transport data over a single copper loop.

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 NTU was designed for use as a

remote unit to the Total Access 3000. The Total Access

SHDSL T1/E1 NTU provides an interface between the

SHDSL network and the customer’s Data Terminal

Equipment (DTE) for applications such as LAN to LAN

bridging, Frame Relay circuit, and PABX termination.

Figure 1. SHDSL T1/E1 NTU Front Panel

The SHDSL T1/E1 NTU is span powered with local DC

power auto-switchover. No adjustments, strapping, or

configuration changes are necessary to power the

module. The SHDSL T1/E1 NTU configuration,

testing, and performance monitoring is managed by the

VT100 local management screen menus, remotely by an

EOC terminal session, or also remotely by EOC

message protocol initiated by the Total Access SHDSL

T1/E1 LTU.

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

All connections of the SHDSL T1/E1 NTU are made

through card edge connectors. The module operates in a

standalone chassis, or the ADTRAN HR12 HDSL

chassis.

When the module is installed in any of the NTU enclo-

sures, all connections are made through the enclosure

backplanes. Ensure chassis ground is properly

connected for either standalone or chassis-mounted

applications.

The SHDSL T1/E1 NTU is designed for a T200 or T400

type form factor housing and inserts into the customer

T1 or E1 T200 type equipment. Follow local practice

for installation of the SHDSL T1/E1 NTU.

The front panel provides LED status indicators for data

port, test, and alarm conditions.

The local management port is a DB-9 female connector

and is labeled V.24, with pinout and interchange circuits

per ITU-T V.24 standards. Table 2 illustrates the local

management port DB-9 pinouts.

LED Indicators

The front panel of the SHDSL T1/E1 NTU has five

LED status indicators. Table 3 lists the LED descrip-

tions.

4. PROVISIONING

The SHDSL T1/E1 NTU menus are accessed via the

DB-9 front panel female connector which supports

VT100 emulation by PC based application programs or

by a virtual terminal session over the EOC.

The parameters of the VT100 terminal should be set as

follows:

• 9600 Baud

• No parity

• 8 Data bits

• 1 Stop bits

• No Flow Control

Once these steps have been completed, the following

options will appear in the SHDSL T1/E1 NTU Main

Menu:

1. Unit Information

2. Provisioning

3. Status

4. Test

5. Performance History

Windows HyperTerminal

Windows HyperTerminal can be used as a VT100

terminal emulation program. Open HyperTerminal by

selecting Programs/Accessories/HyperTerminal. Refer

to the Help section of HyperTerminal for additional

information.

NOTE

To ensure proper display background, select

VT100 terminal emulation under Settings.

The menu tree in Figure 3 illustrates the path to every

provisioning, performance, and test access point in the

SHDSL T1/E1 menu system.

Table 4 lists the complete set of configurable options

with settings and factory default values.

NOTE

When the NTU is in T1 mode, all related E1

options will be non-applicable. A non-appli-

cable option setting is still changeable, but will

not take affect until the option become appli-

cable.

5. OPERATION

Test Capabilities

The SHDSL T1/E1 NTU has the following test capabil-

ities:

• Self diagnostics

• Local loopbacks

• EOC initiated remote loopbacks

• Inband remote loopback detection (E1 mode only)

• Internal bit error rate tester (BERT)

Self Diagnostics

The SHDSL T1/E1 NTU performs self diagnostic tests

of its Read Only Memory (ROM), Random Access

Memory (RAM), LEDs, and non-volatile configuration

setting upon power-up.

Local and Remote Loopbacks

For troubleshooting purposes, the SHDSL T1/E1 NTU

provides three types of loopback tests.

1. Dual sided

2. Network

3. Customer

Inband Loopback Detection

Inband remote loopback response is supported on the

E1 port. The SHDSL T1/E1 NTU supports V.54 and

PN127 inband signalling protocols.

BERT

The SHDSL T1/E1 NTU contains a built-in Bit Error

Rate Test (BERT). The BERT involves injecting and

detecting a Pseudorandom Binary Sequence (PRBS)

toward the network on the selected payload (i.e. G.703

or entire SHDSL payload). The PRBS used in the

SHDSL T1/E1 NTU is PRS15 as defined in ITU-T

0.150 and 0.151. It is also known as 2e15 – 1 pattern.

Customer Port

The SHDSL T1/E1 NTU 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

• Supports ISDN-PRA V3 service

• Displays additional status information via a local

VT100 management screen

See Table 5 for E1 port statistics definitions.

T1 Mode

In T1 mode the port features are as follows:

• Carries information at the rate of 1.544 Mbps

• Uses Superframe Format (SF) or Extended Super-

frame Format (ESF)

• Operates in either Alternate Mark Inversion (AMI)

or Bipolar w/8-Zero Substitution (B8ZS) line code

• Provides programmable timeslot idle pattern

• Monitors the Facility Data Link (FDL) for loopback

commands

• Displays additional status information via a local

VT100 management screen

See Table 6 for T1 port statistics definitions.
