Important Safety Instructions
1. Read and follow all warning notices and instructions marked on the product or
included in the manual.
2. This product is intended to be used with a three-wire grounding type plug – a plug
which has a grounding pin. This is a safety feature. Equipment grounding is vital to
ensure safe operation. Do not defeat the purpose of the grounding type plug by
modifying the plug or using an adaptor.
Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for
the presence of earth ground. If the receptacle is not properly grounded, the
installation must not continue until a qualified electrician has corrected the problem.
If a three-wire grounding type power source is not available, consult a qualified
electrician to determine another method of grounding the equipment.
3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable
operation of the product and to protect it from overheating, these slots and openings
must not be blocked or covered.
4. Do not allow anything to rest on the power cord and do not locate the product where
persons will walk on the power cord.
Safety Instructions
5. Do not attempt to service this product yourself, as opening or removing covers may
expose you to dangerous high voltage points or other risks. Refer all servicing to
qualified service personnel.
6. General purpose cables are provided with this product. Special cables, which may be
required by the regulatory inspection authority for the installation site, are the
responsibility of the customer.
7. When installed in the final configuration, the product must comply with the applicable
Safety Standards and regulatory requirements of the country in which it is installed. If
necessary, consult with the appropriate regulatory agencies and inspection
authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth grounds of two
or more buildings. If products installed in separate buildings are interconnected, the
voltage potential may cause a hazardous condition. Consult a qualified electrical
consultant to determine whether or not this phenomenon exists and, if necessary,
implement corrective action prior to interconnecting the products.
In addition, if the equipment is to be used with telecommunications circuits, take the
following precautions:
– Never install telephone wiring during a lightning storm.

Overview
The COMSPHEREr DualFlow data service unit
(DSU) provides simultaneous digital data service (DDS)
and backup connections to support Frame Relay and
router
-based applications.
The DDS portion provides basic non-rate adapted,
non-diagnostic access using the DSU’
The backup portion (either a V.32, 4-wire Switched 56, or
2-wire Switched 56 DBM) provides simultaneous
rate-adapted, diagnostic access to the switched network.
T
wo versions are available:
•
The standalone Model DualFlow 3615 DSU is
designed for desktop or shelf operation.
• The carrier-mounted (nest- or rack-mounted)
Model DualFlow 3616 DSU is designed for
operation in the COMSPHERE 3000 Series Carrier.
Each DualFlow DSU is equipped with an integral dial
backup module (DBM) for operation over the Public
Switched Telephone Network (PSTN), often referred to as
the dial network, or the Switched 56
The following sections describe the DSU’
features, as well as the features of the integral DBMs.

• NMS control. The DSU can be controlled by
COMSPHEREr 6700 or 6800 Series NMS. Both
NMSs operate using Advanced Diagnostic protocol
(ADp).
The Model 3615 DSU requires a hubbing device
for connection to the NMS; the Model 3616 DSU is
connected to the NMS through the shared
diagnostic unit (SDU) in the COMSPHEREr
3000 Series Carrier.

Before You Begin
Your
installation site should be clean, well-lighted,
well-ventilated, and free from environmental extremes.
A dedicated grounded ac outlet that is protected by a
circuit breaker should be installed within 6 feet of the
DSU’s planned location. The outlet should be capable of
supplying 90 to 132 Vac 60 Hz (U.S. and Canada). At the
branch site, the circuit must be capable of supplying a
minimum of 2 amperes at 115 Vac. Refer to the Technical
Specifications section in Chapter 1 for additional power
requirements.

COMSPHERE DualFlow Data Service Units
CAUTION
The ac transformer contains a
3-wire grounding-type plug
which has a grounding pin.
This is a safety feature. Do
not defeat the purpose of the
grounding plug by modifying
it or by using an adapter.
Prior to installation, use an
outlet tester to check the ac
receptacle for earth ground. If
the power source does not
provide a ground connection,
consult an electrician to
determine another method of
grounding the DSU before
proceeding with the
installation.
Before connecting the DSU, you need to contact the
telephone company to coordinate your installation before
connecting the DSU to the DDS or Switched 56 kbps
network. The DSU can only be operated at the data rate
for which access to the DDS network is provided. In
addition, the DSU must be connected to the dial network.
Refer to the notice at the fr
compliance with FCC, Bell Canada, and Canadian DOC
rules.
No on-site assembly of the DSU is required. However,
installation should not proceed if any of the following is
missing:
• A power cord with table-top ac transformer
• A 14-ft cable for connection to the DDS network,
with an 8-pin RJ48S modular plug on each end
• A 14-ft cable for connection to the permissive dial
network, with a 6-pin RJ11C modular plug on each
end (feature number 3600-F3-503)
For programmable services, the following dial
interface cable should have been ordered.
• Programmable (RJ45S) – an 8-pin modular plug at
each end (feature number 4400-F1-
For Canadian purchasers, an 8-pin RJ48S connector is
on one end while a 6-pin connector is on the other is
required (order feature number 3000-F1-006).

Where to Place the DSU
As mentioned earlier
6 feet of a dedicated grounded ac outlet that is protected
by a circuit breaker.
The distance between the DSU and its DTE must be
within EIA-232-D/V.24 limits, or V.35 limits if operating
the DSU at speeds greater than 19.2 kbps.
• For the EIA-232 connector, the typical maximum
distance is 50 feet at speeds less than or equal to
19.2 kbps. If a longer distance is needed, use high
quality
, low capacitance cable and ensure that the
effective shunt capacitance of the circuit (measured
at the DSU and including the capacitance of the
cable and the DTE) does not exceed 2500
picofarads, as specified in EIA-232-D.
