Things to Know Before Installation
The COMSPHERE Model 3610 DSU with the TDM or MCMP option is delivered with
default hardware settings, factory default configuration option settings, and
factory-installed software.
Port 1 of the DSU is preconfigured to operate with the TDM or MCMP capability
enabled. The DSU includes the factory default configuration option settings for
FacT with some defaults based on hardware.
For the Model 3610, all additional ports are disabled and preconfigured for EIA-232
port interface operation. Each port configured for V.35 needs an interconnect cable
(Feature Number 3000-F1-510).
Once a DSD model is powered up, you can verify the port interface switch setting
through the right side of the back panel.
— If set for EIA-232, you will see a green light.
— If set for V.35, you will see a yellow light.

Installing the DSU
The Model 3610 DSU is designed for desktop operation.
Place the DSU in the planned location.
Allow 1 to 2 feet of clearance for cable connections, space for the ventilation slots
on the sides, and clearance at the rear for the cable connections.
Hardware Settings
!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.
TDM/Flex and MCMP/Flex models are available with two or six ports. When your
firmware version is 6.33 or greater, each port can be set individually for either EIA-232
or V.35 using the front panel, an async terminal, or an NMS.
Based on your model, you may need to perform one of following procedures. Use ID
from the Status branch to obtain the firmware version.

Adding the MCMP/TDM Flex Option to a
Model 3610 DSU
An MCMP/TDM circuit card assembly (CCA) can be added to an installed DSU. The
MUX CCA must be physically and electrically connected to the DSU. The Model 3610 is
installed into a larger base.
The MCMP/TDM Flex model is designed so that each port can be set individually to
either EIA-232 or V.35 by using either the front panel, an async terminal, or an NMS.
The firmware version must be 6.33 or greater.
Adding a MUX CCA
To upgrade a 3610 DSU with a MUX CCA:
Procedure
1. Fold the TDM/Flex or TDM/Flex flat cable over the side of the new expanded base.
2. Position the DSU over the expanded base.
3. Proceed to
Reassembling the DSU on page 8.
Replacing an Installed MUX CCA
To replace an existing MUX CCA:
Procedure
1. Release the two snaplocks holding the MUX CCA in the base. Remove the MUX
CCA.

the front corners, and the #4 screw with the captive lock-washer at the back corner.
2. Connect the flat cable’s 40-position header to the DSU as shown on page 5.
3. Connect the keypad flat cable by inserting the cable into its connector as far as it
will go, then pushing down on the latching mechanism.
4. Being careful not to bend the pins, align the LCD flat cable with its connector. Push
the cable into place.
5. Align the rear panel and four snap tabs. Replace the cover over the expanded
base, allowing the four tabs to snap into place.

Powering Up the DSU
CAUTION:
The power cord contains a 3-wire grounding-type plug which has a
grounding pin. This is a safety feature. Grounding of the unit is vital to ensure
safe operation. Do not defeat the purpose of the grounding plug by modifying
it or by using an adapter. Prior to installation, use an outlet tester or voltmeter
to check the ac receptacle for earth ground. If the power source does not
provide a ground connection, consult an electrician to determine another
method of grounding the unit before proceeding with the installation.
"Procedure
1. At the rear of the DSU, insert the small end of the power cable into the receptacle
labeled POWER.

CAUTION:
Only use the power transformer designed for the Model 3610 DSU. Using
other transformers may result in personal injury or damage to the equipment.
2. Connect the 3-prong plug at the other end of the cable to an ac outlet.
Power-Up Routine
When you apply power the first time, the DSU performs a power-up routine and:
HDetermines what hardware options are installed. This may include MUX to
represent TDM or MCMP.
HAutomatically runs a Device Test on the DSU and each installed hardware option.
All front panel lights flash on and off.
HIf a TDM or MCMP is installed, MUX appears as Pass or Fail on the LCD.
Refer to your User’s Guide for power-up messages and steps for saving and changing
configuration options.
If a Fail message appears or an installed hardware option does not appear, refer to
Document No. 3610-A2-GB46 for DSU troubleshooting and Document No.
3610-A2-GB49 for DBM troubleshooting.

10
DTE Connections
Make the DTE connections as described in the User’s Guide.
In a TDM or MCMP application, all ports default to EIA-232 port interface operation. For
MCMP/TDM Flex, Ports 1 through 6 can be set individually to EIA-232 or V.35 by using
the MUX port configuration options.
For an EIA-232 connection with distances greater than 50 feet or data rates higher than
19.2 kbps, use short, high quality cable with low capacitance and a DTE capable of
supporting the distance and data rate.
When Port 1 requires a speed higher than 19.2 kbps, it is recommended that the port
interface be set to V.35. An interconnect cable is required for every port (2 through 6)
that is set to V.35 interface.
Reconfiguring Ports
If you have a MCMP/TDM Flex with a firmware version 6.33 or greater, you can
configure each port for either EIA-232 or V.35 interface compatibility from the front
panel, an async terminal, or an NMS.
To set a port for EIA-232 or V.35 operation:

Network Verification Testing
Perform verification testing after any installation.
"Procedure
1. Request a device Identity report from each tributary to ensure that the DSU is
addressed properly (ID from the Status branch).
NOTE:
The Model 3610 is delivered with its network address set to 254.
2. Perform a Digital Test on the DDS circuit to ensure that the network is functioning
(DT from the Test branch).
Perform a Digital Test on each:
— Active port when MUX Funct is set to TDM
— Tributary DSU when MUX Funct is set to MCMP
NOTE:
A control DSU can originate a Digital Test in a point-to-point or multipoint
network. Use Position in the Diagnostic General configuration option table to
set a unit to Cntrl.
A
tributary DSU can originate a Digital Test in a point-to-point network only,
provided the configuration option Respond to Remote Digital Loopback
(RespondRDL) is enabled in the control.
Front Panels
The front panel is the user interface to the DSU. There are two types of front panels:
HFront panel on the Model 3610 DSU.
HSDCP (shared diagnostic control panel) used with the Model 3611 DSU in a
COMSPHERE 3000 Series Carrier.
Front panel operation does not vary with the addition of DSU options (DBM, TDM,
MCMP, or SNA Diagnostic Interface). However, menu or selection displays may vary
based on installed options. Refer to the User’s Guide for basic front panel, display,
keypad, and menu function information.

Menu Structure
A 3600 Series DSU comes factory-loaded with default configuration settings:
Model 3610 DSU is configured as a tributary (FacT)
Model 3611 DSU is configured as a control (FacC)
DSU with MCMP/TDM comes configured as a TDM
Menus and Modes of Operation
A DSU without TDM or MCMP operates in Basic mode. A DSU equipped with TDM or
MCMP can operate in one of several modes. The mode of operation affects which
menus appear and the selections available within the menus. Use the MUX Function
configuration option to set the mode of operation.
Access to all network management tasks from the front panel begins at the top-level
menu, the head of the menu hierarchy. Press the key from anywhere in the menu
to return to the top-level menu.
