Installing the DFSIG
Cisco IPICS supports voice interoperability between radio frequency subsystems
that support conventional P25 radio systems. To enable this support, you install
and configure the Cisco Digital Fixed Station Interface Gateway (DFSIG).
The DFSIG installs and operates on a dedicated Cisco Multiservices Platform
Series server. The appropriate operating system is installed on this server at the
factory. For a list of supported servers, see Cisco IPICS Compatibility Matrix.
The DFSIG installation process consists of two general procedures: First you
configure the Multiservices Platform Series server for your environment, then you
install and configure the DFSIG software on the Multiservices Platform Series
server.

DFSIG Overview
The DFSIG is an optional software package for Cisco IPICS. It runs on a Cisco
Multiservices Platform Series server and provides the connectivity between Cisco
IPICS and the conventional P25 radio systems with which you will interoperate.

Configuring the Multiservices Platform Series Server for Your Environment
The DFSIG includes the following components:
•
P25 Gateway—Handles the transcoding between the G.711 codec of a
multicast stream and the Improved Multi-Band Exitation (IMBE) codec
•
Console Arbitrator (CAR)—Handles the implementation of the DFSI
standard and interoperability with DFSI-capable fixed stations
The DFSIG provides these interoperability modes:
•
Channel selection
•
Repeater mode selection (direct/talkaround or repeater)
•
Squelch
•
Supplementary services—STRETCH
•
Encryption
•
Console priority
•
Emergency calls
Configuring the Multiservices Platform Series
Server for Your Environment
Before you install the DFSIG software on a Cisco Multiservices Platform Series
server, you must configure various network and system settings on the server for
your environment.
To configure the Cisco Multiservices Platform server, perform the following
steps.
Procedure
Step 1
Power on the Multiservices Platform server and log in to the server with the user
name root and the password ipics.
Step 2
Execute the reconfigure command:
[root]# reconfigure
Step 3
When you are prompted whether you want to reboot the server, press Y then press
Enter.

Configuring the Multiservices Platform Series Server for Your Environment
The server begins the reboot process. After a few minutes, the Welcome window
appears.
Step 4
At the Welcome window, click Forward to display the Root Password window.
Step 5
In the Root Password window, take these actions:
a.
In the Confirm fields, enter a password for the root user.
The root user has access to all the files in the server. Cisco IPICS requires that
you use strong passwords that meets these guidelines:
– Minimum of 8 characters in length
– At least one upper case letter
– At least one upper case letter
– At least one number
– At least one of the following special characters:
@[]^_`!"#$%&'()*+,-./:;{<|=}>~?
Note
b.
Step 6
If you need to change the root password at a later date, you can log in to
the Cisco IPICS server as the root user and change it by using the
reset_pw command. For more information, refer to the “Using the Cisco
IPICS CLI Tools and Service Commands” chapter in Cisco IPICS
Troubleshooting Guide.
Click Forward.
In the GRUB Password window, take these actions:
a.
In the Confirm fields, a password for the GRUB (boot loader) menu.
The boot loader password enables access to the boot loader menu, which
allows a system administrator to boot the server into single-user mode.
Single-user mode is required to recover a lost root password.
This password must contain at least 6 characters.
b.
Step 7
Click Forward.
In the System User window, take these actions to create a system user, which is
the user who performs administrative tasks on the server:
a.
In the User Name field, enter a unique user name for the system user.

b.
(Optional) In the Full Name field, enter the first name and last name of the
system user, or a brief description of this user.
c.
In the Password and Confirm fields, enter a password for the system user.
This password has the same requirements as the root password that you
entered in Step 5.
d.
Step 8
Step 9
Click Forward.
In the Network Setup window, take these actions:
a.
In the Host Name filed, enter the fully-qualified hostname for this server.
b.
In the IP address field, enter the IP address for this server.
c.
In the Subnet Mask, field, enter the subnet mask for this server.
d.
In the Gateway field, enter the IP address of the default gateway that this
server uses.
e.
In the Primary DNS field, enter the IP address of the primary DNS for this
server.
f.
(Optional) In the Secondary DNS field, enter the IP address of the secondary
DNS for this server.
g.
(Optional) In the Tertiary DNS field, enter the IP address of the Tertiary DNS
for this server.
h.
Click Forward.
In the Timezone window, take these actions:
a.
Choose the correct time zone for your area.
You can choose the time zone from the map or from the list.
b.
If your system clock uses Universal Coordinated Time (UTC), make sure that
you check the System Clock uses UTC check box. Cisco recommends that
UTC be used, particularly in Cisco IPICS deployments that include high
availability.
c.
Click Forward.

Step 10
In the Date and Time window take either of these actions, then click Forward:
•
If your network uses the Network Time Protocol (NTP), choose the Network
Time Protocol tab and check the Enable Network Time Protocol check box.
Enter the name or IP address of an NTP server in the Server field, and click
Add. Repeat to add additional servers. To delete a server, choose the server,
and click Delete.
If you configure NTP on the server, your system administrator should provide
instructions to the IDC users to also configure the Windows Time Service on
their IDC client machines to enable synchronization between the IDC and the
server logs. For detailed information about configuring the Windows Time
Service, go the Microsoft support site and search for Article ID 307897.
If you install a time-bound license for your system, use caution when
enabling NTP. Adjustments to the system date can cause Cisco IPICS to
invalidate your license.
Cisco recommends that NTP be used, particularly in Cisco IPICS
deployments that include high availability.
•
Step 11
If your network does not use NTP, choose the Date & Time tab and enter the
current date and time in the appropriate fields.
In the Finish Setup window, click Finish.
The system bootup process continues and the system processes an internal check.
When the bootup process completes, the log in prompt appears.
Installing the DFSIG Software
After you configure the Cisco Multiservice Platform server for your environment,
you are ready to install the DFSIG software on the server.
