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 3-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 3-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.

or silk-screened text that contains, among other information, the FCC registration number and
Ringer Equivalence Number (REN) for this equipment. If requested, please provide this
information to your telephone company.
The REN is useful to determine the quantity of devices you may connect to your telephone line
and still have all of those devices ring when your number is called. In most, but not all areas, the
sum of the RENs of all devices should not exceed 5. T o be certain of the number of devices you
may connect to your line, as determined by the REN, you should call your local telephone
company to ascertain the maximum REN for your calling area.
If your DSU causes harm to the telephone network, the telephone company may discontinue your
service temporarily . If possible, they will notify you in advance. But if advance notice is not
practical, you will be notified as soon as possible. You will be advised of your right to file a
complaint with the FCC.

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’s V.35 connector.
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 T elephone Network (PSTN), often referred to as
the dial network, or the Switched 56 kbps digital service.
The following sections describe the DSU’s standard
features, as well as the features of the integral DBMs.
Refer to the appropriate section for DBM feature
information.
Standard Features
The DualFlow DSU offers the following features:
• Multispeed operation. The DSU operates at data
rates of 2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64CC kbps
full-duplex over the DDS network.
• T wo DTE connectors (interfaces) are provided:
EIA-232-D and V.35. Use the EIA-232-D
connector for router-management data or backup;
use the V.35 connector for user data.
• LADS operation. The DSU can operate as a local
area data set (LADS) (sometimes called a
limited-distance modem, or LDM) at 2.4, 4.8, 9.6,
19.2, 38.4, 56, or 64kbps.
• 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.
T echnical specifications of the DSU and various DBMs
are near the end of this chapter.

COMSPHERE DualFlow Data Service Units
• Diagnostic Control Panel control. The
Model 3615 DSU is controlled from its diagnostic
control panel (DCP). The diagnostic control panel
for the Model 3616 DSU, called a shared diagnostic
control panel (SDCP), is installed in the
3000 Series Carrier. Both control panels display
information about the DSU on 2-line, 16-character
liquid crystal display (LCD) and through
light-emitting diode (LED) status indicators.

V.32 DBMs
The V.32bis 14.4 kbps dial backup module (referred to
as V.32 DBM throughout this guide) is attached to the
DSU. The V.32 DBM provides the following features:
• Multispeed nondisruptive point-to-point
connections. The DBM provides point-to-point
service over the 2-wire dial network. Backup rates
available are 2.4, 4.8, 9.6, 12.0, and 14.4 kbps.
DBM and DDS connections can be active at the
same time.
• Independent operation. Although the DBM is
installed on the DSU, the two are configured
separately and most tests can be run on either
independent of the other (e.g., you can run a test on
the DBM while a test is running on the DSU).
• Security. There are four levels of call setup
security: None, Password, Callback, and Alarm.
With Alarm, the DBM only answers incoming calls
when an alarm is detected on the DDS line.
• Management control. Dial backup can be initiated
from a 6700 or 6800 Series NMS, the DSU’s DCP,
or it can be initiated automatically by the
DSU-DBM.
DBM Features
DualFlow DSUs are ordered with one of the following
features:
• V.32bis 14.4 kbps dial backup module (DBM)
• 2-Wire Switched 56 DBM
• 4-Wire Switched 56 DBM
Refer to the appropriate section for specific DBM
features.
• DTR control setup. When configured for DTR call
control (DTRCallCon: Orig) backup, the
DSU-DBM initiates dial backup when the DTE
raises data terminal ready (DTR) to the DSU-DBM.
• Rate Adaption. With this feature, the DSU-DBM
can adapt its data rate to a low-speed application
while operating over a higher speed switched
circuit.
• Port Async/Sync. The port asynchronous-to-
synchronous feature makes it possible to send
asynchronous data over the synchronous network.
• Nondisruptive Diagnostics. When set up to use
nondisruptive diagnostics, the local DSU-DBM
sends diagnostic data over the dial connection
without interrupting or disrupting customer data.
• Full tributary diagnostics. The DSU-DBM
supports a full complement of diagnostic tests and
commands when a call is established on a backup
line. Diagnostics can be addressed to and sent to a
tributary from a 6700 or 6800 Series NMS
workstation, or from the DCP of a control DSU.

About Your DualFlow DSU
Switched 56 DBMs
The Switched 56 DBM is attached to the DSU and
offers dial backup capability through the Switched
56 kbps digital service. The Switched 56 DBM offers the
following features:
• Nondisruptive point-to-point connections. The
DBM sends its line data to the EIA-232 port, which
is not used for DDS data. DBM and DDS
connections can be active at the same time.
• Independent operation. Although the DSU and
Switched 56 DBM are functionally integrated, they
are configured separately and can run most tests
independently (e.g., you can run a test on the DBM
while a test is running on the DSU).
• Network compatibility. The Switched 56 DBM,
either the 2-wire or 4-wire version, provides service
over compatible Switched 56 kbps switched
services, such as AT&T’s ACCUNETr Switched
56 kbps Service, MCI’s 56 kbps Switched Digital
Service, Northern T elecom’s DataPatht service,
and US SPRINT’s VPN56 using either dedicated
2-wire or 4-wire access, or local exchange carrier
2-wire or 4-wire switched access. This DBM
operates at 56 kbps full-duplex, and uses
proprietary rate adaption to support data rates of
less than 56 kbps.
• Security. The Switched 56 DBM offers four levels
of call setup security: None, Password, Callback,
and Alarm. Alarm allows the DBM to only answer
incoming calls when there is a Facility Alarm on
the DDS line.
• DTR control setup. When configured for DTR call
control (DTRCallCon: Orig) backup, the
DSU-DBM initiates dial backup when the DTE
raises data terminal ready (DTR) to the DSU-DBM.
• Management control. Dial backup functions can
be controlled from a 6700 or 6800 Series NMS, the
DSU’s DCP, or automatically by the DSU-DBM.
• Rate Adaption. With this feature, the DSU-DBM
can adapt its data rate to a low-speed application
while operating over a higher speed switched
circuit.
• Port Async/Sync. The port asynchronous-to-
synchronous feature makes it possible to send
asynchronous data over the synchronous network.
• Nondisruptive Diagnostics. When set up to use
nondisruptive diagnostics, the local DSU-DBM
sends diagnostic data over the dial connection
without interrupting or disrupting customer data.
• Full tributary diagnostics. The DSU-DBM
supports a full complement of diagnostic tests and
commands when a call is established on a backup
line. Diagnostics can be addressed to and sent to
tributaries from a 6700 or 6800 Series NMS
workstation, or from the DCP of a control DSU.

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 front of this guide to ensure
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, the DSU must be placed within
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.
• For the V.35 connector, the maximum distance
recommended between the DSU and the DTE is
nominally 1000 feet.
Allow 1 to 2 feet of clearance around the DSU for
access and cable connections during installation.
Installing the DSU
Before installing the DSU, label the circuit breaker that
protects the ac wall outlet, and make sure that it is set to
ON. T o proceed with the installation:
" Procedure
1. Place the DSU in its planned location. Make sure
the ventilation slots are not blocked.
2. At the rear of the DSU (Figure 2-2), insert the ac
transformer, circular plug into the interface labeled
POWER.
3. Plug the ac transformer’s 3-prong plug into the ac
wall outlet.
CAUTION
Only use the power
transformer designed for the
Model 3615 DSU. Using other
transformers may result in
personal injury or damage to
the equipment.
