Installation Procedure
Before installing the DSU/CSU, read the Important Safety Instructions beginning on
page 25.
The following procedure is for experienced DSU/CSU users who are familiar with the
3160 DSU/CSU installation process and have no special requirements for their
application. See the
ACCULINK DSU/CSU Operator’s Guide for more information.
1. Attach the power cord to the rear of the DSU/CSU and the other end to a grounded
115 Vac power outlet.
2. Attach the DSU/CSU network connection to the T1 network using the appropriate
cable. Attach the 3160 DSU/CSU to the customer premises equipment via the DTE
(DSX-1) and/or port connectors.
3. Power on the DSU/CSU to perform the power-on self-test.
4. If you intend to use front panel emulation, connect the cable from the PC to the
COM port on the rear panel of the DSU/CSU.
5. If you intend to manage the DSU/CSU with SNMP over an Ethernet LAN, connect
the 10BaseT port to your LAN and assign an IP address to the port. See
Configuration Procedures on page 4.
6. If you do not intend to use the DTE Drop/Insert T1 port, disable it. See
Configuration Procedures on page 4. The default setting for this port is Enabled.
7. Customize the configuration options for your environment as required.
8. During the power-on self-test, the FAIL LED flashes, then all LEDs blink twice.
When the test is complete, verify that the DSU/CSU is functional by observing that
the OK, NETWORK SIG, and DTE SIG LEDs are lit.

12. Press F2 (Edit) to edit the subnet mask. Press F3 (Save) to save the value.
Configuring the DTE Port
Network DS0s must be mapped to the DTE port for DSX-1 voice to a PBX. To assign
Network DS0s 1 through 12 to the DTE port for voice traffic to a PBX:
1. From the top-level menu screen, select Cnfig.
2. Select Activ.
3. Select Edit.
4. Select DTE.
5. Using Table 1 as a guide make sure that the DTE port is enabled and that the
framing and coding are appropriate for the PBX. If the DTE port will not be used,
make sure that it is disabled.

6
Configuring the Data Ports
Network DS0s must be mapped to the Data Ports for data. To configure the DataPort:
1. From the top-level menu screen, select Cnfig.
2. Select Activ.
3. Select Edit.
4. Select Port.
5. Press the Function key under the port to be configured.
6. Using Table 2 as a guide, make sure that the proper port type is selected (V.35,
EIA 530, RS-449, or X.21).
7. Check any other options which may be needed.
Allocating Data Ports
To select the data port:
1. From the top-level menu screen, select Cnfig.
2. Select Activ.
3. Select Edit.
4. From the Edit screen, press the key until the Chan selection appears on the
screen.

8. The configuration option for the data port channel allocation destination appears on
the screen. Select NET to assign this port to the network interface, select DTE to
assign this port to the DTE Drop/Insert (DSX-1) interface, or press the key and
the appropriate Function key to assign this port to another port.
9. Press F1 (Next) to display the appropriate configuration options on the screen. Use
one of the following examples, depending on whether you are assigning by block,
ACAMI, or individual channel.

7

key scrolls the channels onto the screen in groups of three. Select the channel
by pressing the Function key under the desired number. Port n appears. The port is
assigned to that channel. To deallocate a port, press the Function key under that
port number.

8
Allocating DS0 Channels from the DTE Drop/Insert Interface to the
Network Interface
By using the configuration options, you can allocate DS0 channels from the DTE
Drop/Insert (DSX-1) interface to the network interface and specify which DS0 channels
carry Robbed Bit Signaling (RBS) information for voice channels.
To allocate DS0 channels from the DTE Drop/Insert (DSX-1) interface to the network
interface:

screen.
5. Select Chan.
6. From the Channel Config screen, select DTE.
7. From the DTE Channels screen, press F1 to select Assign.
8. Press the Function key below the network channel desired. Each time that you
press the Function key, the DTE channel number is incremented. If the network
channel is currently unassigned (‘‘–” is displayed on Line 2), the DTE channel
number initially displays the same number as the corresponding network channel
number. However, if the network channel is currently assigned, the DTE channel
number is shown as D
n. Pressing the Function key for D24 wraps the display back
to D1. Only those channels that are not already assigned appear on the LCD when
scrolling. The network channels assigned to ports (Prt1...Prt4) are unavailable for
assignment.
To specify DTE Drop/Insert (DSX-1) channels used to carry voice information,
1. Press from the channel allocation screen to return to the DTE Channels
screen.
2. From the DTE Channels screen, press F2 to select Voice.
3. Line 1 displays the 24 DS0 channels for the DTE Drop/Insert (DSX-1) interface.
Pressing the or key scrolls the channels onto the screen in groups of three.
Line 2 displays whether the DS0 channel in Line 1 is a data channel (Data) or a
voice (RBS) channel. Each time that you press the Function key located below the
desired channel, the display in Line 2 toggles between Data and RBS.
