1. PRODUCT DESCRIPTION
The ADTRAN®4-wire 3192 HDSL4 Transceiver Unit for the Remote end (H4TU-R), P/N 1223426L12, is a
network terminating unit used to deploy an HDSL4 T1 circuit using 4-wire metallic facilities. See Figure 1. This
H4TU-R is designed to be installed in a 3192 chassis.
The 3192 H4TU-R, Span Powered can be deployed in circuits using one H4TU-C, one H4TU-R, and up to two
H4Rs.
The 3192 H4TU-R, Span Powered terminates local loop HDSL4 signals originating from the Central Office (CO)
unit and transforms the HDSL4 signal into traditional DS1 signals to be delivered to the customer.

Installation 3192 H4TU-R, Span Powered Installation and Maintenance Practice
This version of the H4TU-R works with multiple list versions of the HDSL4 Transceiver Unit for the Central
Office (H4TU-C) and repeater (H4R) as listed in Table 1.
NOTE: x = any generic release number
The 3192 H4TU-R, Span Powered can be used with any H4TU-C to complete a fully span-powered HDSL4
circuit. Span power is provided from the H4TU-C.
Compliance
Table 2 shows the compliance codes for the 3192 H4TU-R, Span Powered. This product is intended for installation
in equipment with a Type “B” or “E” enclosure.
This product meets all requirements of Bellcore GR-1089-CORE (Class A2), ANSI T1.418-2002 and is NRTL
listed to the applicable UL standards.
2. INSTALLATION
After unpacking the unit, inspect it for damage. If damage is discovered, file a claim with the carrier, then contact
ADTRAN. Refer to Warranty and Customer Service on page 33 in this practice. The settings on the H4TU-C are
encoded and transmitted to the 3192 H4TU-R, Span Powered once the circuit has achieved synchronization. There
are no switch settings on the 3192 H4TU-R, Span Powered.

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.
WARNING
Up to –200 VDC may be present on telecommunications wiring. Ensure chassis
ground is properly connected.
Installation Procedure
To install the 3192 H4TU-R, Span Powered, perform the following steps:
1. If present, remove the Access Module Blank from the appropriate access module slot of the chassis.
2. Hold the 3192 H4TU-R, Span Powered by the front panel while supporting the bottom edge of the module.
3. Align the module edges to fit in the lower and upper guide grooves for the access module slot.
4. Slide the module into the access module slot. Simultaneous thumb pressure at the top and at the bottom of the
module will ensure that the module is firmly positioned against the backplane of the chassis.
3. FRONT PANEL OPERATION
The 3192 H2TU-R front panel controls consist of the following hardware for analysis of the HDSL4 circuit:
• Pushbuttons
• LED indicators
• Bantam jacks
• DB-9 RS-232 port
Pushbuttons
The front panel contains two pushbuttons. These are labeled LOC and REM.
The LOC pushbutton controls a bidirectional loopback at the H4TU-R. Pressing the button causes a bidirectional
loopback to occur. If the bidirectional loopback is active, pressing the button a second time will disable the
loopback.
The REM pushbutton controls a bidirectional loopback at the H4TU-C. Pressing the button causes a loopback
toward the H4TU-R and network to occur. If the loopback is active, pressing the button a second time will disable
the loopback. Refer to HDSL4 System Testing on page 7 for further details.

Front Panel LED Indicators
There are seven front panel mounted status LED indicators. Each indicator is described in Table 3.
Front Panel DS1 Monitor Jack
The 3192 H4TU-R, Span Powered provides DS1 monitor bantam jacks. These jacks provide a test point for DS1
traffic to and from the customer. Refer to HDSL4 System Testing on page 7 for details.
Remote Provisioning
There are no configuration switches for the 3192 H4TU-R, Span Powered. Configuration is performed via software
discussed in the Control Port Operation section of this practice.
The provisioning settings can be viewed and manipulated through management access via the front panel RS-232
port. Table 4 lists the available provisioning options and their factory default settings.

5. HDSL4 SYSTEM TESTING
The 3192 H4TU-R, Span Powered provides diagnostic, loopback, and signal monitoring capabilities.
The front panel LEDs provide diagnostics for HDSL4 loops, DS1 signals, alarms, provisioning, and loopbacks.
Refer to the Installation section for details.
The H4TU-R provides a bidirectional loopback via the loopback (LBK) buttons on the front panel. Refer to the
H4TU-R Network Loopbacks and Customer Loopbacks sections for more details.
DS1 MON Bantam Jacks
The MON jacks provide a non intrusive access point for monitoring the characteristics of the transmit and receive
signals at the DS1 interface point.
For example, the DS1 MON jack on the H4TU-R could be used to connect to a bit error rate tester to monitor for
synchronization, test patterns, etc.
Figure 3 is an illustration of specific jack detail.
NOTE
For the MON jacks, the TX and RX indications relate to the direction of the signal
to/from the CPE.

The H4TU-R responds to multiple loopback activation processes.
• First, manual loopback on the H4TU-R and/or the H4TU-C unit can be controlled from the front panel. Refer
to Front Panel Operation on page 3 of this practice for more detail.
• Second, loopback activation can be accomplished using the control port of the H4TU-R.
• Third, the H4TU-R responds to the industry standard HDSL loopback codes as designated in the ANSI
document T1E1.4/92. These are described in Appendix A, HDSL4 Loopbacks.
• Fourth, the H4TU-R responds to T1 Network Interface Unit (NIU) loopback codes as described in Bellcore TR-
TSY-000312. These codes are as follows:
In-Band Codes
Loop up 11000 (2 in 5)
Loop down 11100 (3 in 5)
ESF Codes
Loop up 1111 1111 0100 1000 (FF 48)
Loop down 1111 1111 0010 0100 (FF 24)
Receiving the in-band codes for more than five seconds or the ESF codes four consecutive times will cause the
appropriate loopback action. The ESF codes must be transmitted in the Facility Data Link (FDL).
NOTE
The NIU loopback option must be enabled before the H4TU-R can respond to the
NIU loopback.
The H4TU-R responds to the loopback codes by activating the NIU loopback from either the disarmed or armed
state. The loop down codes return the H4TU-R to the disarmed or de-activated state depending upon the code
utilized.
Customer Loopbacks
In addition to loopbacks in the direction of the network, the H4TU-R can also be looped back in the direction of the
customer. The H4TU-C and H4TU-R Customer Side Loopbacks are illustrated in Figure 4.
NOTE
Network and customer loopbacks are governed by the loopback time out option
(Default=120 minutes).

Control Port Operation 3192 H4TU-R, Span Powered Installation and Maintenance Practice
6. CONTROL PORT OPERATION
The H4TU-R provides a front panel-mounted DB-9 connector that supplies an RS-232 interface for connection to a
controlling terminal. The pinout of the DB-9 is illustrated in Figure 5.
Figure 5. RS-232 (DB-9) Connector Pinout
The terminal interface operates at data rates from 1.2, 2.4, 4.8, 9.6, and 19.2 kbps. The asynchronous data format is
fixed at 8 data bits, no parity, and 1 stop bit.
NOTE
If a personal computer with terminal emulation capability is being used, be sure to
disable any power-saving programs. Otherwise, communication between the PC
and the HDSL4 unit may be disrupted, resulting in misplaced characters or screen
time outs.
Operation
The screens illustrated in this section apply to an HDSL4 circuit deployed with the ADTRAN HDSL4 technology.
The circuit includes an H4TU-C, up to two H4Rs and an H4TU-R. Other configurations are possible (such as use
of another vendor's equipment) and their displays will vary slightly from those shown in this section.
A terminal session is initiated by entering multiple spacebar characters which are used by the H4TU-R to deter-
mine the speed of the terminal. Once the speed has been determined, an HDSL4 Main Menu is displayed.
This ADTRAN HDSL4 Main Menu provides access to detailed performance and configuration information. The
Operation, Administration, Maintenance, and Provisioning (OAM&P) screens are available as listed on the Main
Menu (Figure 6).
To access a particular menu item, press the number associated with that item, and press ENTER.
