DESCRIPTION

This Quick Start provides instructions for the installation of the

GPON TA352/TA374 Optical Network Termination (ONT) units (P/N:

1287802F1C, 1287803F1C). The GPON TA352 4th Gen ONT has two

POTS ports and two Gigabit Ethernet ports; the GPON TA374 2nd Gen

ONT has four POTS ports and four Gigabit Ethernet ports.

The ONTs are enclosed in a weather-hardened Network Interface Device

(NID) which mounts to the exterior of a building. The figure below

illustrates the TA374 ONT in the context of the NID with the access door of

the NID removed.

Figure 1. Example NID Enclosure

The ONT is a Class 1 Laser Product.

INSTALLATION

This section explains NID installation and all cable routing.

After unpacking the ONT, inspect it for damage. If damage is noted, file a

claim with the carrier and then contact ADTRAN. For more information,

refer to the warranty.

4. Mount the NID to the side of the subscriber’s premise.

Ground the NID

Install the ground connection by completing the following steps (refer to

Figure 4 for ground cable routing):

f CAUTION!

Do not use a knife to cut the opening in the rubber grommets. This

can result in an excessively large hole and compromise the integrity

of the unit and allow moisture into the unit.

1. Refer to Figure 4 and insert the ground wire through the rubber

grommet.

2. Remove 1 inch of the insulation jacket from a 6 AWG

minimum copper ground wire.

Figure 4. Inserting the Ground Wire

3. Loosen the set screws on the ground bar.

4. Insert the ground wire in the ground bar and tighten set screw.

5. Route the ground wire 12 inches below finished grade by the

shortest and most direct route to the AC power ground system to

connect to a ground. Ensure the wire is free of any sharp bends.

6. Attach the ground wire to the side of the subscriber’s premises with

stainless steel half moon clamps or tie-wrap the ground wire to the

riser conduit of the Buried Fiber Drop.

7. Clean the Multi Grounded Neutral (MGN) connector with emery

cloth to ensure a stable connection.

8. Attach the ground wire from the NID to the MGN connector with the

appropriate UL approved ground clamp/fitting.

9. Coat the connection with a metal corrosion preventative.

10. Attach a Warning Ground Tag to the grounding connection.

f CAUTION!

Align the captive screw on the bottom of the ONT with the screw hole

on the Ground Bar and tighten (refer to Figure 12) to ensure

grounding for the ONT. This should be the last step before closing the

NID.

Install the ONT

To install the ONT in the NID Housing, align the hinges on the ONT with

the mounting points on the NID Housing and snap the two together (refer

to Figure 5).

Install a Local Power Source

f WARNING!

The ONT must be powered by a UL Listed Power Supply suitable for

the application (rated 12 VDC, 1.25 A minimum) with an LPS output.

Installation of the Local Power Source will be dictated by on-site

conditions and local telephone company practices.

f CAUTION!

To reduce the risk of fire, use minimum no. 26 AWG

telecommunications line cord.

Install the UPS

Installation of the Uninterruptible Power Source (UPS) will be dictated by

on-site conditions and local telephone company practices. Refer to the

installation material that is provided with the UPS.

f CAUTION!

After the ground wire, fiber jumper, and power leads have been

connected, close the ONT and secure it by tightening the inner

security screw.

Ethernet, power and POTS cables, and attached equipment are

intended for use within the same building with equipotential bonding,

and not intended to be placed in separate buildings or structures.

Failure to deploy as described could result in permanent damage

from lightning or other electrical events and voids the warranty.

If it is necessary to connect the Ethernet ports to remote outdoor

equipment or between structures then add an

appropriate protection device per the following:

ADTRAN's Ethernet Port Protection Device (EPPD) (P/N

1700502G1) should be connected between the unit and the outside

plant cable. Use of any Ethernet protector other than ADTRAN's for

this purpose will void the user's warranty.

LED STATUS

The LED table below provides the LED status for the ONT.

REGISTRATION ID

There are two instances where the OLT will register the ONT:

■Serial Number Activation (performed by the OLT when the ONT is

“Discovered”)

■Registration ID using a lineman’s handset (see below)

Set Registration ID Activation using Lineman’s Handset

To set the Registration ID using a DTMF Keypad on a standard lineman’s

handset, complete the following steps:

g NOTE

The ONT does not need to be connected to the OLT during the

Registration ID process.

Only POTS port 1 can be used for Registration ID configuration.

1. Perform an initial power-up on a new ONT.

g NOTE

At the start-up of the ONT, a 10-second Registration ID

configuration window is provided.

2. Wait for the indication that Registration ID configuration is available.

The GPON LED will be flashing green on a 200 millisecond interval

when Registration ID configuration is available.

3. Go off-hook and observe that dial tone is heard.

g NOTE

Once a dial tone is heard by going off-hook during the Registration ID

window, you have 10 seconds to enter the initial digits *00. Once *00

is entered, you have 300 seconds to complete the Registration ID

process.

4. After a dial tone is heard, enter

*001234*XXXXXXXXXX*XXXXXXXXXX*, where XXXXXXXXXX is

the Registration ID for this site.

g NOTE

Only digits 0-9 are supported.

5. If entered correctly, a confirmation tone is played and the number is

displayed on the phone’s caller-id display with the string

“ACCEPTED”.

6. If programming is successful, the ONT plays a stutter dial tone and

flashes the GPON LED green for approximately 10 seconds with a

cadence of 300 milliseconds on/off before it continues its startup/

ranging process.

g NOTE

If a failure occurs, the ONT plays reorder tone and displays **Invalid**

on the caller-id display. If the pattern is entered incorrectly, the caller-

id displays **Re-enter* if the first ID does not match the second.

Entering an invalid Registration ID, such as one with less than 10

digits or non-matching values, results in a reorder tone and you have

the same 10-second window to restart step 3 to allow you to re-enter

codes that were entered incorrectly.
