Overview
A Model 3611 DSU is delivered with default strap
settings and factory-installed software options, and is
ready to connect to the network. The Model 3611 DSU is
configured as a control DSU for operation at 9.6 kbps on a
point-to-point circuit, with the diagnostic protocol set to
ADp.
The Model 3611 DSU is designed for installation in a
COMSPHERE 3000 Series Carrier, which supplies
operating power and provides interfaces for connecting to
the DDS and, if required, analog networks. Up to
16 DSUs can be installed in a COMSPHERE 3000 Series
Carrier. Refer to the COMSPHERE 3000 Series Carrier,
Installation Manual for carrier installation procedures.
There are two types of Model 3611 DSUs: the
non-modular Model 3611 DSU and the Modular 3611
DSU. The non-modular Model 3611 DSU has two DTE
connectors (a 25-pin EIA-232-D/V.24 connector and a
34-pin V.35 connector ) mounted directly onto the rear
edge of the circuit card. With this type of DSU, the DTE
cables must be disconnected at the rear of the carrier
before the DSU can be removed. The Modular 3611 DSU
contains "gold finger" contacts on the rear edge of its
circuit card that plug into a rear connector plate. The rear

connector plate is mounted onto the rear of the carrier and
has two DTE connectors. With this type of DSU, the DTE
cables do not have to be disconnected before removing the
DSU.
The rear connector plate shipped with the
Modular 3611 DSU contains two 25-pin DTE connectors,
a 25-pin EIA-232-D/V.24 connector and a 25-pin V.35
connector. It is shipped with a modular DSU V.35 adapter
for use when a V.35 interface is needed. (V.35 is
recommended for speeds of 19.2 kbps or greater.) The
adapter provides an interface between the DSU's 25-pin
D-type connector and the DTE cable's V.35 connector.
A shared diagnostic control panel (SDCP), installed in
the carrier, is required for installation and maintenance of
the Model 3611 DSU.
Installation of the DSUs and carrier-related equipment
consists of the following procedures and should be
performed in the order listed.
