Overview
The Model 3610 DSU, designed for desktop operation,
is delivered with default hardware strap settings and
factory-installed software options, ready to connect to the
network. The unit is configured as a tributary DSU for
operation at 9.6 kbps on a point-to-point circuit, with
diagnostic protocol set to ADp.
When a TDM or MCMP is installed, Port 1 of the DSU
is configured to operate at 9.6 kbps with the TDM or
MCMP capability enabled; all other ports are disabled.
For the Model 3610, the additional ports provided by
the TDM or MCMP are 25-pin D-type connectors, which
require an interface between each 25-pin D-type
connector and V.35 connector. Order a V.35 adapter
(feature number 3000-F1-510) for each TDM or MCMP
port that you intend to operate as a V.35 interface. All
ports are configured for EIA-232 operation before leaving
the factory.
If you ordered a new Model 3610 DSU with a
TDM/Flex or MCMP/Flex, it may be a 2- or 6-port
version. You can configure each port independently to
operate as either an EIA-232 or V.35 interface. Ports are
configured via the DCP, an async terminal, or an NMS
through the Configuration (Confg) branch of the menu.
If you ordered a Model 3610 TDM/DSD or
MCMP/DSD for digital-sharing device (DSD)
applications, which only comes in a 6-port version, turn
the option card on the TDM or MCMP so all ports can
operate as either EIA-232 or V.35 interfaces.
If you ordered a TDM/Flex or MCMP/Flex field
installation upgrade and have a DSU with a firmware
version less than 6.3x, set the TDM or MCMP switch to
change all ports from EIA-232 to V.35 operation; they
cannot be set via the DCP. These ports should be set
during the installation, but they can be changed as needed
provided you have the required V.35 adapter or adapters.
Only the 6-port TDM/Flex or MCMP/Flex can be used
with DSUs with firmware version (DSU SW ver:) less than
6.3x. For further information regarding ordering
equipment, see Appendix C, Equipment List, in the
