This chapter contains only installation information that
is specific to a TDM or MCMP, including the Flex and
DSD options.
NOTE
Unless specifically noted, TDM
refers to a TDM, TDM/Flex, or
TDM/DSD, and MCMP refers to
an MCMP, MCMP/Flex, or
MCMP/DSD.
TDM or MCMP installation consists of the following
procedures, which should be performed in the order listed.
•Physical installation of the TDM or MCMP.
•Change the S1 hardware strap (if necessary).
•Changing the switch position for the TDM/Flex or
MCMP/Flex for a DSU having a firmware version
less than 6.3x, or orientation of the TDM/DSD or
MCMP/DSD option card (if necessary).
•Electrical connection.
•Network diagnostic connection.
•Software configuration.
•DDS network (or LADS) connection.
•PSTN or switched 56 kbps network connection
(if the DBM is installed).
•DSU DTE connection.
•Operation verification.
Although the Model 3610 DSU is designed for desk- or
table-top operation, an ACCULINKr 3100 Series CSU
wall-mount adapter may be ordered to mount the DSU
with TDM or MCMP on a wall, an equipment shelf, a
19-inch RS-310-C or 23-inch AT&T DATAPHONEr
equipment cabinet. To order the adapter, refer to
Equipment Lists, Appendix L, of the COMSPHERE
3600 Series Data Service Units, Models 3610 and 3611,
Operator’s Guide.
For DSU installation information, order the
COMSPHERE 3600 Series Data Service Units, Models

Diagnostic Interface installation information, order the

Options, Applications Guide.
Hardware Straps
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.
The 6-port Model 3610 TDM/Flex or MCMP/Flex has
two switches with hardware straps (refer to Figure 2-1).
•Switch S1 is for configuring a 6-port TDM/Flex or
MCMP/Flex for EIA-232 or V.35 interface
compatibility when the DSU’s firmware version is
less than 6.3x; all ports are configured for either
EIA-232 or V.35 operation. You can only use a
6-port TDM/Flex or MCMP/Flex with a DSU that
has a firmware version of less than 6.3x.
S1 is ignored if the DSU’s firmware version is 6.3x
or greater; the 2-port TDM/Flex or MCMP/Flex
does not have S1.
•Switch S2 is only located on an MCMP/Flex; these
straps must not be changed.
For the TDM/DSD and MCMP/DSD with selectable
V.35 or EIA-232 interface compatibility on all ports via an
option card, there are two hardware straps or switches that
are for factory testing only. These two straps or switches
must not be changed. They should remain in the
positions shown in Figure 2-2.
Most straps for the TDM or MCMP are set as
configuration options. For additional DSU hardware strap
information, refer to the COMSPHERE 3600 Series Data
Units, Models 3610 and 3611, User’s Guide.
