Overview
The COMSPHERE
r
3600 Series Data Service Units
(DSUs), Models 3610 and 3611, support communication
between computers and other data processing devices by
providing connections to digital transmission facilities.
NOTE
All of the technical information in
this manual applies to both DSU
models, the Model 3610 DSU and
the Model 3611 DSU, unless
otherwise noted.
There are two types of Model 3611 DSUs:
•
Non-modular Model 3611 DSU. The non-modular
DSU provides two DTE connectors (a 25-pin
EIA-232-D/V.24 connector and a 34-pin V.35
connector) on the rear edge of its circuit card. The
DTE cables must be disconnected before removing
the non-modular DSU from the COMSPHERE
r
3000 Series Carrier.
•
Modular Model 3611 DSU. The modular DSU
provides “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 3000 Series Carrier. Using this version of the
DSU, DTE cables do not have to be disconnected
before removing the DSU.
