Radio Frequency Interference Regulations
The equipment described in this document has been tested and found to comply with the
limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against interference when equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
interference to radio communications.
Changes or modifications not expressly approved by Telenetics could void the user's author-
ity to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emissions from
digital apparatus set out in the radio interference regulations of the Canadian Department of
Communications.
Operation of this equipment in a residential area is likely to cause interference, in which case
the user will be required to take adequate measures to correct the interference at his/her own
expense.
This product was verified under test conditions that included use of shielded DTE cables.
Use of different cables will invalidate verification and increase the risk of causing
interference to radio and TV reception.
You can obtain the proper cables from Telenetics.

If the equipment is damaged, contact the shipper. If you have further concerns about
damage or missing parts, contact Telenetics:
The 3512 is wrapped in reusable shock-absorbent packing material. Save the carton
and packing material in case you later want to ship or store it.
Caution
All 35XX devices, such as 3500s, 3512s, and 3520s, should be
used in environments designed for computers and electronic
equipment. In areas susceptible to lightning, take
precautions to prevent damage to electronic equipment.
Contact your telco, or an electronics accessories vendor, for
information on lightning protection equipment. Customers
experiencing problems due to surges from lightning have
eliminated such problems by installing surge suppressors
on power and data lines connected to 35XX devices.

Perform the following steps:
1) Connect the primary-line cable to the rear panel DDS jack and to the primary
line jack.
2) For integral restoral, connect the restoral cable to the rear panel ALT jack and
to the restoral line jack, OR
For external restoral, connect an A/B switch crossover cable to Port 2 and to
an external restoral device.
Caution
Install cables with the ferrite end adjacent to the 3512 or 3512
SDC. The ferrite bead or cylinder ensures that your unit oper-
ates in compliance with FCC RFI requirements.
3) IMPORTANT: Use the permanently attached cable connector mounting
screws to secure cables to Port 1.
On a 1-port 3512, connect a DTE cable to a DTE or host computer and to Port 1.
On a 2-port 3512, connect:
• A DB25-pin DTE cable to a DTE or host computer and to Port 1.
• A DB26-pin DTE cable from Port 2 to a DTE.You may need an adapter
cable. NOTE: When using an adapter cable, screw the EIA 232-C/D
cable connector onto the adapter cable before connecting to the 3512.
On a 3-port 3512 SDC, connect:
• A DB25-pin DTE cable to a DTE or host computer and to Port 1.
• DB26-pin DTE cable(s) from Ports 2 and 3 to a DTE(s). You may need an
adapter cable. NOTE: When using an adapter cable, screw the EIA 232-
C/D cable connector onto the adapter cable before connecting to the 3512.
On a 4-port 3512, connect:
• A DB25-pin DTE cable to a DTE or host computer and to Port 1.
• A DB26-pin DTE cable(s) from Ports 2, 3, and 4 to a DTE(s).You may
need an adapter cable. NOTE: If you are using a Motorola Codex adapter
cable, screw the standard EIA 232-C/D cable connector onto the adapter
cable before connecting to the 3512.
IMPORTANT: 3512 ports support data rates up to 56.0 kbps (64 kbps with
the 64k CC feature). At data rates greater than 19.2 kbps, Telenetics
recommends that you configure the unit for the V.35 electrical interface. When
using a 326XFAST Series Modem for external restoral, refer to the 326X
Series Modem documentation to determine cable capacitance.
4) To connect one 3512 to an NMS, link the NMS control channel to a DB25-pin
Network Adapter cable. Connect this cable (through a junction box) to an 8-
pin DIN adapter cable, and the adapter cable to the 3512 NC IN connector.

1-6 Installation
To connect multiple 3512s (or comparable devices) to an NMS in a daisy-
chain configuration, use the cabling above, plus an 8-pin DIN cable from the
first 3512 NC OUT connector to the next NC IN connector, and so on.
Figure 1-2 shows how to cable devices to an NMS this way.
Figure 1-2. Multiple Devices in a Daisy Chain Connection to NMS
5) Plug in the power cord to the 3512 and the power source. The 3512
automatically runs its self-test.
6) View the self-test results:
•If the 3512 is working properly, the default message displays.
•If the 3512 fails the test, an error message displays; the unit resets itself
and reruns the self-test. If it fails the test again, it may need service.
Call Telenetics.
This completes the physical installation. Next, test the data line, as described in
Chapter 2.

Verifying Line Quality
IMPORTANT:
1) Follow this procedure to verify the quality of data-communications lines
before configuring an application and before contacting the telephone
company or Telenetics. If tests do indicate a line problem, follow the action(s)
below. Do not bring the 3512 online until you can run error-free tests.
2) On multipoint DDS-I type circuits, with MP-Mux-supported functionality,
follow this procedure to between each master-slave pair, and then configure
for MP-Mux operation.
To verify line quality:
1) If the unit has the DualVIEW feature or is managed by a Telenetics or Motor-
ola Network Management System (NMS), set NC Override=On (*MODIFY
main menu, MODIFY NETWORK category).
2) Set all devices to DTE Con=Normal (*MODIFY, MODIFY PORT).
3) Set the Opmode to match the DDS service type (MODIFY DSU category).
4) Confirm that the line rate is correct for the application, as follows:
a) Set Data Rate=Auto (MODIFY DSU category). NOTE: The Data Rate
default option is Auto.
b) Wait 60 seconds, then check the rate display (*STATUS main menu).
c) Set the line rate to match the DDS service rate (using Data Rate).
5) If the AL LED is red, check the general alarm queue (*STATUS main menu,
ALARM STATUS category).
If the ST LED is not red, continue with Step 6.
6) Set a unique Network Control (NC) address for each device.
(*MODIFY main menu, MODIFY NETWORK category.)
7) Run a line pattern loopback test to the remote device, as follows (for details on
running this test, refer to the 3512 DSU/CSU User’s Manual, Chapter 8,
Testing and Troubleshooting):
First, initiate a Remote Loop 2 test on the local 3512 (this test puts the remote
unit into loopback; it transmits received data back towards the local 3512):
a) Under the *TEST menu, press until LOOPBACKS displays.
b) Press until Rm Loop 2=Off displays.
c) Press to select Rm Loop 2:P1.
d) Press . Rm Loop 2=P1 displays. The loopback is now active.

Verifying Line Quality 2-3
The T/R LED turns steady orange. The ST LED should flash green.
With Remote Loop 2 active, run a pattern test, as follows:
a) Press until PATTERN TESTS displays.
b) Press until Type=Space displays.
c) Press until Type:511 displays.
d) Press . Type=511 displays.
e) Press until Pattern=Off displays.
f) Press until Pattern:On displays.
g) Press . Pattern=On displays.
Next, the T/R LED turns steady orange. If:
•The ST LED flashes green, proceed to Step 8
•The ST LED flashes red, there may be a line problem. Before reporting it
to the telephone company, disable the Pattern test (set Pattern=Off),
disable the Remote Loop 2 test (set Rm 2 Loop=Off), and then run a
Device Bit Error Rate (DBER) test at both units, as described in Step 8
8) Run a DBER test as follows:
a) Under the *TEST menu, press until BER TESTS displays.
b) Press until Te st Ty p e =Device displays.
c) Press until BER=Off displays.
d) Press . BER:On displays.
e) Press . The BER test runs.
9) Turn off the BER test (set BER=Off), if it is not already off.
10) Interpret the front panel display as follows:
When the lines are verified, configure your application, as described next.
If this Displays... Do This:
BER Pass
BER ERRORS=000
Report the problem to the telephone company
BER Fail
BER ERRORS=x
Contact Telenetics
