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 STA TIC-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.
