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.

!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. 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.
