1. GENERAL
This practice is an installation and maintenance guide
for the ADTRAN Total Access ® 1500 Single 4-Wire
Equalized Transmission Only (ETO) access module
(P/N 1180113L2). Figure 1 is an illustration showing
the front panel of the Single 4-Wire ETO (4W ETO).
Revision History
This is the initial issue of this practice. Future changes
to this documentation will be explained in this
subsection.
2. DESCRIPTION
The 4W ETO was designed for use in the Total Access
1500 chassis. The 4W ETO provides two individual
voice grade 4-wire analog interfaces between a Voice
Frequency (VF) transmission facility and the Total
Access 1500 chassis backplane. No signaling is
generated by the 4W ETO, but in-band signaling tones
sent as part of the data stream will be transmitted by the
circuit.

Time Slot Assignments
For time slot assignments in the Dual T1 mode and in
the Quad T1 mode, see Table 1.
The Total Access 1500 platform can have multiple time
slots in the T1 data stream assigned to each physical slot
in the channel bank. The Total Access 1500 allows craft
selectable time slots using the electronic provisioning
interface. The system will automatically map DS0s in
the T1 as determined by the LIU operational configuration
or manual mapping is possible via the LIU
configuration menu.

Connections
Two of the four 50-pin male amphenol connectors (P1
through P4) on the rear of the Total Access 1500
chassis provide the interconnections to each of the 24
physical Access Module slots on the chassis. The 4W
ETO uses P1 (T/R) and P2 (T1/R1) for the port 1
connections. See Table 1 for wiring interconnection
details.

HANDLING PRECAUTIONS REQUIRED.
After unpacking the Total Access 1500 4W ETO,
inspect it for damage. If damage has occurred, file a
claim with the carrier, then contact ADTRAN Customer
Service. Refer to the Warranty and Customer Service
section for further information. If possible, keep the
original shipping container for returning the 4W ETO
for repair or for verification of shipping damage.
Shipping Contents
The contents include the following items:
• 4W ETO
• 4W ETO 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.
Instructions for Installing the Module
The 4W ETO inserts into any access module slot (1
through 24) of a Total Access 1500 chassis. To install
the 4W ETO, perform the following steps:
1. If present, remove the Access Module Blank (P/N
1175099L1) from the appropriate access module
slot of the Total Access 1500 chassis.
2. Hold the unit by the front panel while supporting
the bottom side with the ejector latch, located on
the lower left-hand side of the module, at the
bottom and opened to engage the chassis edge
when it is plugged in.
3. Align the module edges to fit in the lower and
upper guide grooves for the designated slot.
4. Slide the module into the access module slot while
pressing equally on the top and bottom of the front
panel until the module is firmly positioned against
the backplane of the chassis.
5. Lock the module in place by pushing in on the
ejector latch.
The 4W ETO initializes and goes operational upon
insertion into an active Total Access 1500 chassis.
Initialization is indicated by the front panel LED.
Front Panel LED
The Total Access 1500 4W ETO has one front panel
LED that provides status information. See Table 3 for
LED indications.

4. PROVISIONING
There are no hardware options in the 4W ETO access
module; its specific options can be provisioned from the
SCU ADMIN port or remote craft interface. The factory
default settings for the 4W ETO access module are
noted in bold text in Table 4 and Table 5.
Table 4. 4W ETO General Options
Function Option Description
Transmit TLP –18.0 to +7.5 dBm (+0.0) Sets the transmit channel attenuation in 0.1 dBm increments
from the customer to the network.

Equalizer Options Height

Slope
Cable Type
–18.0 to +7.5 dBm (+0.0)
–20.0 to +5.5 dBm (+0.0)
Sets the receive channel attenuation, in 0.1 dBm increments
from the network to the customer.
Sets the sealing current mode of operation.
Selects the impedance of the Transmit T/R pair from the
customer toward the T1 network.
Selects the impedance of the T1/R1 pair toward the customer.
See Table 5 for detailed descriptions of the equalizer
provisioning options.
Note: Defaults are in bold type.
(1) Although no restrictions are placed on the termination settings relative to the equalizer settings, the following configurations
are typical: 600 ohms and 1200 ohms impedances can be used in conjunction with active equalization.
The 150 ohms and 600 ohms impedances can be used with mismatched equalization. The 600 ohms impedance can
also be used on short nonloaded loops where no equalization is necessary.
Table 5. 4W ETO Equalizer Options
Function Option Description
Height 0 to 15 In conjunction with Bandwidth Equalization, corrects for
frequency response degradation at the high end of the voice
range due to cable length by increasing the 3250-Hz equalization
bump.
Bandwidth 0 to 15 In conjunction with Height Equalization, corrects for frequency
response degradation at the high end of the voice range due to
cable length by increasing the breadth of the equalization bump.
Slope 0 to 15 Corrects for frequency response degradation at the low end of
the voice range due to cable length.
Cable Type Non-Loaded
Loaded
Used to specify loaded or nonloaded cable. This option modifies
the equalization circuitry to provide greater gain at the higher
frequencies when transmitting over nonloaded cable.

5. TEST FEATURES
The 4-Wire ETO supports a Digital Network Loopback
and 1004 Hz Tone Tests to support circuit turn-up and
maintenance efforts. Test functions can be activated
locally via the ADMIN port on the SCU or remotely via
Telnet or SNMP.
NOTE
The tests cannot run simultaneously. If a test is
in progress and another test is initiated, the first
test will be terminated when the new test starts.
Digital Network Loopback Test
The Digital Network Loopback test activates a
loopback path that takes the DS0 data received from the
network and transmits it back to the network in the
appropriate port's transmit time slot.
1004 Hz Tone Test
The 1004 Hz Tone Test generates a 1004 Hz @ 0 dBm
Digital Reference Signal (DRS) tone, which is used to
send DRS signal to the loop, the network, or to both
simultaneously.
6. MAINTENANCE
The Total Access 1500 4W ETO requires no routine
maintenance for normal operation.
ADTRAN does not recommend that repairs be
attempted in the field. Repair services may be obtained
by returning the defective unit to ADTRAN. Refer to
