3192 HTU-C
INTRODUCTION
This practice is an installation and maintenance guide for the ADTRAN®HDSL 3192 HTU-C
(3192 HTU-C). The 3192 HTU-C (P/N 1247004L1) is used to deploy an HDSL T1 circuit using
4-wire metallic facilities. The unit occupies one slot in a 3192 shelf. Figure 1 illustrates the
3192 HTU-C front panel.

Description
DSX 1 signals are provided to and received from the network while 2B1Q HDSL signals are
provided to the local loop. The 3192 HTU-C works in conjunction with the ADTRAN HDSL
Transceiver Unit for Remote Office (HTU-R) and HDSL Range Extender (HRE) to provide a DS1
service up to 36,000 feet on the local loop.
This 3192 HTU-C works with multiple list versions of the HTU-R and HRE as listed below.
The 3192 HTU-C can be deployed in circuits consisting of one HTU-C and one HTU-R. When
deployment requires the HRE, the 3192 HTU-C can be deployed with one or two (T200, 239, or
819A) and one HTU-R.
The HDSL local loop operates as two independent subsystems, each operating over a single
twisted pair. The 3192 HTU-C communicates over these two twisted pairs to the HTU-R. Each
subsystem carries half of the total bandwidth along with a small amount of overhead used for
maintenance and performance monitoring.
System power and alarm bus connections are made through the backplane of the 3192 shelf.
DSX 1 and HDSL signals are connected through the wire-wrap pins or the 50 or 164-pin shelf
connectors related to each individual slot.
The 3192 HTU-C contains an onboard fuse. If this fuse opens, it supplies a –48 VDC voltage to
the fuse alarm bus; all front panel indicators turn off. This fuse is not field-replaceable.
The 3192 HTU-C uses a DC-to-DC converter to derive its internal logic and span powering
voltages from the –48 VDC office supply. The 3192 HTU-C can span power HREs and HTU-Rs
as listed above. The –190 VDC span powering voltage meets all requirements of Class A2
voltages as specified by Bellcore GR-1089-CORE.

HDSL 3192 HTU-C Installation and Maintenance Practice
461247004L1-5A
CAUTION
Per GR-1089-CORE Section 9, the 3192 HTU-C does not have an
internal DC connection between battery return and frame ground.
As such, it may be installed in a DC-I (isolated) or DC-C (common)
installation. For installations where other cards or the host system
have internal connections between battery return and frame
ground, the system would be intended for deployment only in a
DC-C installation.
NOTE
The HDSL port is classified as Type 1, 3, and 5, as defined in
Appendix B of GR-1089-CORE Issue 4, and meets the lightning
and power fault criteria with any primary protector that meets any
of the voltage limits of GR-974-CORE or GR-1361-CORE (i.e.,
carbon blocks, gas tubes, solid states, etc.).
NOTE
The DSX-1 port is classified as Type 2 or 4 as defined in Appendix
B of GR-1089-CORE Issue 4, and is suitable for connection to
intra-building or unexposed wiring or cabling only. Do not
metallically connect this port to interfaces which connect to the
Outside Plant (OSP) or to the OSP wiring. The DSX-1 port is
designed for use as an intra-building interface only (Type 2 or Type
4 ports as described in GR-1089-CORE Issue 4) and requires
isolation from exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection in order to connect this
interface metallically to OSP wiring.
NOTE
Current limiting protectors are not required.
NOTE
The 3192 HTU-C is designed to operate with a nominal operating
voltage of –48 VDC and a minimum operating voltage of –40 VDC.
The 3192 HTU-C will not be damaged by any steady state voltage
below –56.7 VDC.

HDSL Deployment Guidelines
61247004L1-5A 5
HDSL DEPLOYMENT GUIDELINES
The ADTRAN HDSL system is designed to provide DS1 based services over loops designed to
comply with carrier service area (CSA) guidelines. CSA deployment guidelines are given below.
• All loops are non-loaded only.
• For loops with 26-AWG cable, the maximum loop length including bridged tap lengths is 9 kft.
• For loops with 24-AWG cable, the maximum loop length including bridged tap lengths is 12 kft.
• Any single bridged tap is limited to 2 kft.
• Total bridged tap length is limited to 2.5 kft.
• The total length of multi-gauge cable containing 26-AWG cable must not exceed the
following:
–12–{(3×L26)/(9–LBTAP)} (in kft)
Where:
-L
26 = Total length of 26-AWG cable excluding bridged taps (in kft)
-L
BTAP = Total length of all bridged taps (in kft)
This deployment criteria is summarized in the chart shown in Figure 2.
Loop loss per kft for other wire is summarized in Table 3.

Recommended maximum local loop loss information for PIC cable at 70°F, 135 Ω, resistive
termination is provided in Table 4.
An approximation for the maximum amount of wideband noise on an HDSL local loop as
measured by a 50 kbps filter is ≤31 dBrn.
An approximation for the maximum level of impulse noise as measured using a 50 kbps filter
on an HDSL loop is ≤50 dBrn.
NOTE
These approximations are to be used as guidelines only and may
vary slightly on different loops. Adhering to the guidelines should
produce performance in excess of 10-7 BER.

Line Build Out Switch
The line build out switch is located on the printed circuit board. Manual configuration should
be performed prior to installing the 3192 HTU-C. The available settings are shown in Table 5.
Instructions for Installing the 3192 HTU-C
To install the 3192 HTU-C, perform the following steps:
1. Hold the 3192 HTU-C by the front panel while supporting its bottom edge to engage the
chassis edge.
2. Align the 3192 HTU-C edges to fit in the lower and upper guide grooves for the module
slot.
3. Slide the 3192 HTU-C into the module slot. Simultaneous thumb pressure at the top
(above the DSL1 LED) and at the bottom (below the electrostatic caution symbol) of the
3192 HTU-C will ensure that it is firmly positioned against the backplane of the chassis.
When the 3192 HTU-C first powers up it runs the power up self-tests. Once the power up self-
tests are complete, the status LEDs reflect the true state of the hardware.

CONNECTIONS
The 3192 HTU-C occupies one card slot in a CI Wescom 3192 Office Repeater Bay. Power and
alarm signals are provided to the card through the backplane of the shelf. DSX-1 and HDSL loop
signals are connected to the wire-wrap pins or mass termination shelf connectors corresponding
to the slot the unit occupies. Connections to the DSX pins are intended for intra-building wiring
only. Refer to Figure 3 for 3192 HTU-C edge connector wiring.
The 3192 HTU-C is capable of span powering the HTU-R by applying simplex current to the
local loop. From 10 to 125 mA of current is coupled onto the HDSL span to power the HTU-R
and HRE when deployed.

Alarm Connections
The following alarm signals are connected to the 3192 Alarm Module.
Alarm processing is actually performed by the 3192 Alarm Module. Refer to the 3192 Alarm
Module documentation for further information.
Alarm conditions are not reported at the 3192 HTU-C until the HDSL circuit is terminated by
connecting an HTU-R. This allows circuit pre-provisioning. Once the 3192 HTU-C is termi-
nated with an HTU-R, the 3192 HTU-C goes into an in-service state.
