1. GENERAL
This document is an installation and maintenance
practice for the ADTRAN Total Access® SHDSL T1/
E1 Network Terminating Unit (NTU). Figure 1 illustrates 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.

• SHDSL T1/E1 NTU 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.
When the module is installed in any of the NTU enclosures, 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.
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.
LED Indicators
The front panel of the SHDSL T1/E1 NTU has five
LED status indicators. Table 3 lists the LED descriptions.

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:
•
•
•
•
•
NOTE
9600 Baud
No parity
8 Data bits
1 Stop bits
No Flow Control
To ensure proper display background, select
VT100 terminal emulation under Settings.
Once these steps have been completed, the following

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.
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-applicable option setting is still changeable, but will
not take affect until the option become applicable.

5. OPERATION
Test Capabilities
The SHDSL T1/E1 NTU has the following test capabilities:
•
•
•
•
•
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.
61225236L1-5A
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 Superframe 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.
