Standard DSU Features
The COMSPHERE 3600 Series Data Service Units
(DSUs), Models 3610 and 3611, support communication
between computers and other data processing devices by
providing connections to digital data service (DDS)
transmission facilities.
The 3600 Series DSU offers the following standard
features:
Multispeed operation: Operates on the
DATAPHONE Digital Service network, or
equivalent DDS network, at data rates of 2.4, 4.8,
9.6, 19.2, 38.4, 56, and 64 kbps full-duplex. The
DSU is also compatible with the ACCUNET
Spectrum of Digital Services network (ASDS), and
supports 64 kbps Clear Channel operation on a
72 kbps local loop.
Nondisruptive diagnostics: In a nondisruptive
diagnostic network, transmits all communications
without interruption to user-transmitted data.
Async/Sync conversion: Provides point-to-point
and multipoint asynchronous-to-synchronous data
conversion for DTE ports. The DSU can send
asynchronous data over a synchronous network.
Automatic rate detection: The DSU supports
detection of the DDS data rate automatically.

User-selectable interfaces: Two user-selectable
data terminal equipment (DTE) interfaces for data
rates up to 64 kbps.
— EIA/TIA-232-E interface for operation at data
rates up to 19.2 kbps with standard cable and
rates up to 64 kbps with a low capacitance
cable
— V.35 interface for data rates up to 64 kbps
LADS operation: Can operate as a local area data
set (LADS) at data rates of 2.4, 4.8, 9.6, 19.2, 38.4,
56, or 64 kbps full-duplex (sometimes called a
limited-distance modem or LDM).
Flexible device control: The 3600 Series DSUs
provide access to the COMSPHERE 6700 or
6800 Series Network Management System (NMS)
and are compatible with DATAPHONE II System
Controller, Diagnostic Console, or Network
Controller.
Rate adaption: When a DSU or DBM is operating
with a data rate greater than the DTE, rate adaption
is automatically enabled. Both point-to-point and
multipoint configurations support rate adaption.
Crossed-pair detection: Generates a facility alarm
when the DDS receive and transmit pairs are
crossed.
