1. GENERAL
This practice provides installation and maintenance
(I/M) instructions for the ADTRAN 239 T HDSL4
Repeater (H4R), P/N 22 445L . Figure 1 is an
illustration of the H4R. H4R equipment features
include:
• TC PAM line coding
• Lightning protection
• In-band loopback control
• Standard 239 form factor repeater apparatus case
design
• Remote provisioning and pass-through
performance monitoring
An ADTRAN span powered HDSL4 circuit consists
of an H4TU-C, up to two H4Rs and an H4TU-R. Due
to span power limits, the number of H4Rs permitted in
the circuit depends on the type of H4TU-C used. An
ADTRAN 239 H4R provides DS transport on all
revised resistance design (RRD) 26 AWG and/or 24
AWG loops. Two ADTRAN 239 H4R repeaters
extend the range of a loop up to 42.5 kft (24 AWG).
Repeater placement on single H4R loops depends only
on the attenuation properties of the loop segment.
Repeater placement for dual H4R loops requires both
segment attenuation and segment DC resistance
requirements be satisfied (refer to section 4, HDSL4
Deployment Guidelines).

The H4R is used in conjunction with any T .4 8
compliant span powering T HDSL4 transceiver unit
for the central office (H4TU-C) and HDSL4
transceiver unit for the remote end (H4TU-R).
Compatible ADTRAN HDSL4 transceiver units are as

There are no manual option settings on the H4R.
H4R operating power is derived from an H4TU-C,
independent of line impedance or wire gauge. The
operating power from the H4TU-C is also used to span
power the H4TU-R.

4. HDSL4 DEPLOYMENT GUIDELINES
NOTE
The H4TU-Cs (P/Ns: 1221401L6, 1221403L6,
and 1221404L6) support only one H4R in the
HDSL4 circuit.
The different segments of an HDSL4 circuit are
defined in Figure 2.
1st Segment
H4TU-C 1st H4R 2nd H4R H4TU-R
2nd Segment 3rd Segment
Figure 2. HDSL4 Circuit Segments
According to the number of H4Rs in the HDSL4
circuit, the following service ranges apply:
• HDSL4 circuit containing no H4Rs will reach up
to 16 kft on the local loop (24 AWG)
• HDSL4 circuit containing one H4R will reach up
to 16 kft on the first segment and 15 kft on the
second segment (24 AWG)
• HDSL4 circuit containing two H4Rs will reach to
13.5 kft on the first segment, 14 kft on the second
segment, and 15 kft on the third segment
(24 AWG) *
*This is one example of a circuit with 2 H4 s.
Other loop length configurations are possible in
compliance with loop resistance restraints.
NOTE
Refer to the H4TU-C or H4TU-R Installation
and Maintenance Practice, HDSL4 Deployment
Guidelines section, for other loop parameters
including Insertion Loss and Pulse Attenuation.
The ADTRAN HDSL4 system provides DS -based
services over loops designed to comply with the
guidelines given below.
1. All loops are nonloaded only.
2. Any single bridged tap is limited to 2 kft.
3. Total bridged tap length is limited to 2.5 kft.
NOTE
Refer to the Detailed Status Screen (Main Menu
selection “3,” Span Status selection “1”) for the
current loop SNR Margin, Insertion Loss, and
Pulse Attenuation status.

61221445L1-5A Section 61221445L1-5, Issue 1 7
Each of the three segments associated with span
powering two H4Rs and an H4TU-R must satisfy the
recommended insertion loss, loop attenuation
requirements in addition to the DC resistance budgets.
In general, 22 and 9 AWG segments will be
restricted by their loop attenuation while the DC
resistance will restrict the segment reach for 26 and 24
AWG. When designing a dual H4R loop, the first
segment should have lower DC resistance than the
second segment. Single H4R spans do not require any
restriction due to DC resistance.
The segment resistance (Ω segment) is determined using
the equation provided below.
Ωsegment = L26 * Ω26 + L24 * Ω24 + L22 * Ω22 + L 9 * Ω9
where : L# is the length of # AWG cable (kft,
excluding bridge taps), Ω# is the D.C.
Resistance of # AWG cable
Table 6 lists single pair cable DC resistance values to
be used in the equation above.

Section 61221445L1-5, Issue 1
Once the resistance of each segment is confirmed,
refer to Figure 3 to decide if the H4TU-C is capable
of span powering two H4Rs and one H4TU-R.
Follow these steps to utilize the graph shown in Figure
3:
1. Find the line on the graph which represents the
known third segment resistance. These are the
lines running diagonally across the graph labeled
300 - 1100 ohms. This line represents the upper
limit for 2 H4Rs plus H4TU-R span powering.
2. Find the first segment resistance on the vertical
axis.
3. Find the second segment resistance on the
horizontal axis.
4. Find the instance where the two points from steps
2 and 3 meet on the graph.
5. The point found in step 4 must be below the
upper limit line defined by the third segment
measurement (step 1). If the instance where these
two points is above this line, the H4TU-C cannot
span power two H4Rs and the H4TU-R.
Note that these measurements represent only one of
the two HDSL4 pairs.

An example problem is illustrated in Figure 4. For
this example, begin with three known measurements:
700 ohms first segment resistance, 800 ohms second
segment resistance, and 900 ohms third segment
resistance. See Figure 4 and the following steps to
solve the example problem:
1. Find the 900 ohms third segment resistance line
on the graph. This line is depicted in bold in
Figure 4. This line is the upper span power limit.
2. Find the 700 ohms first segment resistance point
on the vertical axis.
3. Find the 800 ohms second segment resistance
point on the horizontal axis.

5. MAINTENANCE
The ADTRAN 239 H4R requires no routine
maintenance. In case of equipment malfunction,
perform an in-band loopback from the central office
(CO). If a malfunction is confirmed, replace the unit.
The ADTRAN 239 H4R has looping capability through
the channel allowing digital loopback in fault isolation.
The looping is accomplished remotely.
Performance monitoring, diagnostics, and loopbacks
are also available from the craft interface at the
H4TU-C and H4TU-R.
The type of loopbacks that the H4R supports will
depend on what type of transceiver units are used in
the circuit. Refer to the Installation and Maintenance
Practice of the specific H4TU-C or H4TU-C for a list
of loopback codes.
When testing indicates a faulty circuit pack, refer to
the housing Installation and Maintenance Practice for
the entry and pressurization control, then replace the
faulty circuit pack.
ADTRAN does not recommend field repair of this
unit. Repair services may be obtained by returning
the defective unit to the ADTRAN Customer and
Product Support (CAPS) Department.
