Before you install the DSU, read the

Important Safety Instructions

on page 18.

!HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from

damage due to electrostatic discharge (ESD) during normal

operation. When performing installation procedures,

however, take proper static control precautions to

prevent damage to equipment. If you are not sure

of the proper static control precautions, contact

your nearest sales or service representative.

Installation Procedures

This section provides instructions for installing standalone Model 3510 DSUs and

carrier-mounted Model 3511 DSUs. Refer to the appropriate section.

Model 3510 DSU Installation

Physical installation of the Model 3510 consists of unpacking the DSU and placing it in

its planned location. Electrical installation requires the following procedure.

Procedure

1. Coordinate the installation with the telephone company and affected digital network

user locations.

2. Configure the DSU to meet the requirements of the application (refer to

Hardware

Strapping

on page 8). Do not disable the faceplate switches now, or you will

not be able to test the DSU.

3. Find a suitable non-switched ac wall outlet capable of furnishing 90 to 132 Vac,

0.07 amps at 117 Vac. Label the circuit breaker that controls the outlet and be sure

it is set to ON.

4. At the rear panel of the DSU, insert the socket end of the power cable into the

POWER receptacle. Ensure that the connector is fully inserted. Connect the other

end to the ac outlet.

Indicators on the faceplate flash as the DSU performs an internal power-on

self-test. The green OK indicator then lights for about 20 seconds, then the red

OS/NS indicator flashes. If no indicators light, verify that the DSU is receiving

power.

5. Perform the Device Test as described in the

Operation

section of the User’s Guide.

If the DSU fails this test, replace the DSU.

6. Connect the network interface.

The Model 3510 DSU’s rear panel contains a miniature universal service ordering

code (USOC) type RJ48S jack for connecting your DSU to the digital network.

Purchasers in the United States receive a modular telephone cable (D8W-87) with

each DSU, with identical connectors on both ends. Canadian purchasers must

order another cable (Feature Number 3000-B1-006) with a USOC-type RJ48S

connector on one end and a 6-pin connector on the other.

7. Connect the DSU to the digital network by inserting the 8-pin end of the cable into

the connector labeled LINE at the rear of the DSU.

Insert the other end of the cable into the modular jack provided by the telephone

company. Make sure the OK indicator shows green and the OS/NS indicator stops

flashing.

NOTE:

For LADS applications, the OK indicator will not come on and the OS/NS

indicator will flash until both DSUs are connected to the LADS circuit.

8. The DSU has an EIA-232-D/V.24 (ISO 2110) connector and a CCITT V.35

connector. EIA-232-D/V.24 is the factory default setting; Switch S3-6 on the CCA is

positioned toward the front (F). Equipment speeds above 19.2 kbps typically use

the V.35 interface.

To configure the DSU to use the V.35 interface, set Switch S3-6 on the CCA toward

the rear (R) during configuration. Refer to

Hardware Strapping

on page 8 for

additional information.

NOTE:

For the V.35 connector, the recommended maximum distance between a DTE

and a DSU is nominally 1000 feet. For the EIA-232 connector, the effective

shunt capacitance of the circuit, measured at the DSU, including the

capacitance of the cable and the DTE, must not exceed 2500 picofarads, as

specified in EIA-232-D.

9. Insert the plug end of the DTE cord into the appropriate DATA TERMINAL

connector (EIA-232-D or V.35) at the back of the DSU. Connection of the DSU to

the DTE is a matter of selecting and installing the appropriate cable.

Connect the other end of the DTE cord to your DTE.

10. If the network line and remote-end DSU are installed and tested, do a Remote

Loopback – Test Pattern Test (Point-to-Point or Multipoint).

11. If the Front Panel test switches strap is to be disabled, do this now.

Installation of the standalone Model 3510 DSU is complete.

Model 3511 DSU Installation

This section includes the installation procedures for the Model 3511 DSU, which is

designed for installation in a COMSPHERE 3000 Series Carrier. Before installing the

DSU, verify that the carrier has been installed properly and is operational.

CAUTION:

Discharge any static electricity that may be present on your body by

touching a properly grounded object (e.g., cold water pipe, frame ground, or

data cabinet). Do not handle the circuit card unnecessarily.

The initial installation procedure for the Model 3511 DSU requires the installation of a

rear connector plate onto the rear of the COMSPHERE 3000 Series Carrier. After the

initial installation, the DSU can be installed and removed from the front of the carrier

without first disconnecting the DTE cables at the rear of the carrier.

Installing the Rear Connector Plate

To install a DSU and its rear connector plate for the first time:

Procedure

1. Configure the DSU to meet the requirements of the application (refer to

Hardware

Strapping

on page 8). Do not disable the front panel switches at this time.

2. At the rear of the carrier, set the tab on the rear connector plate into one of the slots

on the carrier’s backplane. Make sure the rear connector plate uses the same slot

position intended for the DSU.

3. Loosely fasten the screw attached to the rear connector plate, allowing for slight

adjustment that may be needed when installing the DSU.

4. Using a Phillips screwdriver, loosen the screw holding the circuit pack lock that

secures the DSU’s latch, and rotate the lock to the open position. Open the latch.

5. At the front of the carrier, hold the DSU vertically with the latch on its faceplate in

the open position. Then, insert the circuit card into the top and bottom circuit card

guides for the slot that contains the rear connector plate.

6. Aligning the circuit card with the rear connector plate, slide the DSU into the slot

until the connectors seat firmly into the back of the carrier.

7. Press the faceplate latch to secure the DSU in the carrier, rotate the circuit pack

lock into the closed position, and tighten the screw.

If the carrier is powered, all indicators on the faceplate flash as the DSU performs

an internal power-on self-test. The green OK indicator then lights for about 20

seconds, then the red OS/NS flashes. If no indicators light, verify that the DSU is

receiving power.

8. Return to the rear of the carrier and tighten the rear connector plate screw.

9. At the rear of the carrier, connect the DTE interface cable onto the rear connector

plate.

If using an EIA-232-D interface cable, connect the EIA-232-D cable to the top DTE

connector on the rear connector plate.

Installation of the DSU and its rear connector plate is complete.

Connecting to a V.35 Interface

To connect a V.35 interface cable:

Procedure

1. Connect the 25-pin end of the V.35 adapter to the bottom DTE connector on the

rear connector plate. Tighten the thumbscrews on both sides of the connector.

2. Connect the 34-pin end of the V.35 adapter to the DTE’s V.35 interface cable.

Tighten the screws on both sides of the connector.

Installation of the V.35 interface cable is complete.

NOTE:

For the V.35 connector, the recommended maximum distance between a DTE and

a DSU is 1000 feet. For the EIA-232 connector, the effective shunt capacitance of

the circuit measured at the DSU, including the capacitance of the cable and the

DTE, must not exceed 2500 picofarads, as specified in EIA-232-D.
