Precautions
Before installing your DSU, read the
Important Safety Instructions
on page 19.
!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.

How to Change Hardware Straps
The Model 3615 DSU has a switch located behind its diagnostic control panel (DCP).
This switch contains two straps, one that controls the permissive or programmable
connection for the DBM, and one that controls the frame-to-signal grounds. Table 1
shows the DSU’s switch settings. Use the following procedure to set the switches.
Procedure
1. With your thumbs under the edge of the front bezel, firmly press upward to lift the
bezel from the tabs securing it in place.
2. Swing the front bezel up and set the bezel aside.
3. Refer to Table 1 to determine which switch needs to be changed. Then, using a
small instrument, carefully change the position of the switch.
4. Reinsert the front bezel’s hinge tabs into position and swing the bezel down. Snap
the bezel back into place.

Where to Place the DSU
The DSU must be placed within 6 feet of a dedicated grounded ac outlet that is
protected by a circuit breaker.
The distance between the DSU and its DTE must be within EIA-232-D/V.24 limits, or
V.35 limits if operating the DSU at speeds greater than 19.2 kbps.
For the EIA-232 connector, the typical maximum distance is 50 feet at speeds less
than or equal to 19.2 kbps. If a longer distance is needed, use high quality, low
capacitance cable and ensure that the effective shunt capacitance of the circuit
(measured at the DSU and including the capacitance of the cable and the DTE)
does not exceed 2500 picofarads, as specified in EIA-232-D.
For the V.35 connector, the maximum distance recommended between the DSU
and the DTE is nominally 1000 feet.
Allow 1 to 2 feet of clearance around the DSU for access and cable connections during
installation.

Installing the DSU
Before installing the DSU, label the circuit breaker that protects the ac wall outlet, and
make sure that it is set to ON. Then proceed with the installation.
Procedure
1. Place the DSU in its planned location. Make sure the ventilation slots are not
blocked.
2. At the rear of the DSU, insert the ac transformer, circular plug into the interface
labeled POWER.
3. Plug the ac transformer’s 3-prong plug into the ac wall outlet.
!WARNING:
Only use the power transformer designed for the Model 3615 DSU. Using
other transformers may result in personal injury or damage to the equipment.

Power-Up Routine
When power is applied, the DSU:
HRuns a Device Test on itself and the DBM.
During the tests, all indicators on the DCP light briefly and the message Power-Up
Tests appears on the liquid crystal display (LCD).
HDisplays the results of each test momentarily as Pass, Fail, or Abrt.
(
Abrt indicates
that the Device Test was aborted because a network loopback was in progress
during the power-up procedure.)
These tests take about 20 seconds to complete.
If the DSU or DBM fails this test, follow these steps.
"Procedure
1. Press the key to return to the top-level menu.
2. Select Local (F1 key).
3. Press the key to scroll the
Confg
(Configuration) branch into view.
4. Press the function key directly below Confg.
5. Press the F1 key to select Opts (Configuration Options).
The
Load from
screen appears.
6. Press the key to bring the factory-loaded unit configurations into view, and
select the appropriate configuration. Select:
— SyBC (Synchronous Backup for a Control DSU) for a control when the router
controls backup.
— SyBT (Synchronous Backup for a Tributary DSU) for a tributary when the
router controls backup.
— DiDg (Dial Diagnostics) for asynchronous router-management data to be sent
over the EIA-232 port via the DBM connection and user data over the V.35 port
via the DDS connection.
7. Press the F1 key to SAVE the selected configuration.
The
Save to
screen appears.
8. Save the selected configuration to Activ (F1 key).
9. Press the key to return to the top-level menu, then select Local again.
10. Select Test (F3).
The
Run Test on
screen appears.
11. Select the device that Failed: the DSU or DBM.
12. Press the F2 key to run the Device Test again.
The device should pass.
13. Should the device fail, contact your service representative.

Connecting to the Network
The DSU provides three interfaces. One jack connects the DSU to the 6700 or 6800
Series NMS, one connects the DSU to the dial (or public switched telephone network –
PSTN) network, and one connects the DSU to the DDS network. Follow the appropriate
procedure when making your network connections.
Connecting to the NMS
A 3600 Hubbing Device is required to connect the control DSU to the 6700 or 6800
Series NMS. When connected to the NMS, the DSU can be controlled and configured
from the NMS rather than from the DCP alone.
Procedure
1. Plug the 4-pin modular plug of the 3600 Hubbing Device into the DSU jack labeled
CC/DC.
2. Plug one end of an M6BJ cable into the hubbing device jack labeled CC IN/DC
OUT.
3. Plug the other end of the 6-pin M6BJ cable into the 6-pin end of the 873A adapter.
4. Plug the D-type end of the 873A adapter into the appropriate 6700 or 6800 Series
NMS jack.
Refer to your COMSPHERE 6700 or 6800 Series NMS documentation to control and
configure the DSU from the NMS.

Connecting to the Dial (or PSTN) Network
If your DSU is equipped with a V.32 DBM, follow these steps to connect it to the dial
network.
Procedure
1. Plug either end of the dial (analog) interface cable into the DSU jack labeled
BACKUP.
— For permissive
service, use a telephone cord with an 6-pin modular RJ11C
plug.
— For programmable
service, use a telephone cord with an 8-pin RJ45S plug.
2. Plug the other end of the cable into the modular jack provided by the telephone
company, USOC RJ11C (permissive) or USOC RJ45S (programmable).
3. If your site has programmable service, verify that the DSU’s hardware strap S1-1 is
switched to the Off position.

Connecting to the Switched 56 kbps Network
NOTE:
Before connecting the DSU to the Switched 56 kbps network, ensure that approved
primary protectors have been installed on the circuit in accordance with Article 800
of the National Electric Code, NFPA 70, in the United States and Section 60 of the
Canadian Electric Code, Part 1, in Canada.
If the DSU is equipped with a 4-wire Switched 56 DBM, an 8-pin cable is provided; if a
2-wire Switched 56 DBM, a 6-pin cable is provided.
!WARNING:
Do not insert the 2-wire Switched 56 kbps plug into an RJ11C jack. This type
of jack is intended for analog public switched telephone network (PSTN)
devices. Doing so may cause equipment damage and harm to the telephone
network.
To make a physical connection to the Switched 56 kbps network, follow these steps.
Procedure
1. Plug either end of the Switched 56 kbps network interface cable into the DSU jack
labeled BACKUP.
— For the 2-wire Switched 56 DBM, use the 6-pin cable.
— For the 4-wire Switched 56 DBM, use the 8-pin cable.
2. Plug the other end of the cable into the modular jack provided for the
Switched 56 kbps network connection.
