2 NI223 iDen Radio Interface

A

1 General

The NI223 is an iDen interface box
designed to connect the IP-223
Ethernet Adapter Panel to an iDen
radio phone system, primarily the
Nextel network. The IP-223/NI223

LAN/WAN

combination will make the Nextel
network an IP asset to any
Telex/Vega IP base consoles. (C-Soft,
C-6200, IP-1616 or IP-2002) The IP­223 must be placed in iDen Radio
Mode to control the NI223. iDen Radio Mode is selected in the Multicast Setup Screen of the IP-

223. See Figure 1. Note, iDen Radio Mode is only available in IP-223 Software Versions

1.09 and higher.

Figure 1 Multicast Setup Screen IP-223 Showing iDen Radio Setup

Each line has a pull down menu that allows selection of iDen Radio Mode. The multicast address
and port numbers are configured just as any other mode, with the exception of the ring signal.
Standard phone calls can be made through the iDen interface and the IP223. The ringing signal is
broadcast on a unique multicast address. The ringing signal broadcast must be known to all
listening consoles, therefore, make sure the configuration for the ring multicast and port numbers
are consistent on the IP-223 and any listening console. For console configurations, please refer to
the specific User Manual for that product.

3 NI223 Setup and Alignment Procedure

3.1 IP-223 Setup

3.1.1 Jumper Settings

Jumper position Connection Type:
“B” Balanced 600 Ohm
Line 1: J3, J9 ,J11, J16, J21
Line 2: J25, J28, J29, J19, J20

“A” 600 Ohm Rx Termination
Line 1: J14
Line 2: J24

Serial Port Communications Jumpers: iDen Radio Mode
Line 1: J35 “B”
Line 2: J26 “B”

3.1.2 Web Page C onfiguration

Figure 1 shows the Multicast Setup page. This is the location that iDen Radio Mode is initially
configured via the pull down menu for Channel Type. It must be done first to allow the iDen
Radio Setup page to be displayed. The iDen Radio Interface can be used to make Direct Connect,
Group Call or Alert Calls in a normal radio sense. The multicast fields are setup using normal
radio configurations. Figure 2 shows the iDen Radio Setup page. The right most column holds
the iDen Radio Direct Connect numbers. The number placed in this field will be associated with
a Function tone. When a Console changes to that Function tone and Transmits, that Direct
Connect number will be sent to the iDen Radio and if available, a connection will be made. If
using the iDen Radio interface is used to make a phone call, the multicasts are unused, as a
TCP/IP socket connection is made in the same manner as Phone mode.

3.2 Connecting the IP-223 and the NI223

Figure 3 Connection between IP-223 and NI223

NI223 iDen Radio Interface 5

Connect the IP-223 and the NI223 as shown in Figure 3. The power for the NI223 will be
obtained from the same power connector the IP-223 is using. Make sure the polarities are correct
to avoid damaging the units. Figure 3 shows the iDen Radio configured for use with IP-223
Radio 1. Either or both radio ports on the IP-223 could be used. If both ports are used, a DB9
splitter cable is required to route serial channel one and two to their respective NI223’s. This can
be purchased from the factory. Part number: 301953

3.3 iDen Radio Setup

At power up or reset, with the iDen Radio properly connected, the display on the IP223 should
show “iDen” on the line that was enabled, either the top(line 1) or bottom(line 2) of the display.
If after connecting and configuring the IP-223 properly you do not see “iDen” on the display,
you should check the following items:

1) First double check that you have everything connected as described above.

2) Check that the IP-223 did get enabled for iDen Radio mode, then reset.

3) Check that the Jumpers for the serial communications are correctly set.

4) Make sure the baud rate of the radio is set at 19200. This will differ from radio to radio,
but as an example, in the i315: Press the menu button. Then select Settings, then
Advanced, then Baud Rate and finally 19200.

3.4 C-Soft Setup

NOTE: This example shows a basic setup for C-Soft. Please refer to the User manual for other
Vega IP based consoles if necessary.

3.4.1 Setup IP Multicast List

Figure 4 Setup IP Multicast List – iDen Radio in Phone Mode operation

Figure 4 shows an example of setting two lines in Phone mode. In this example, the Line Type is
selected as Phone mode. The Line Name is arbitrary and called Line 31 and Line 32 in the case.
The Rx port numbers need to be unique, typically they are just the next number in a standard
assignment sequence. The Base Radio IP address will be the IP address of the IP-223 that is
connected to the NI223.

3.4.2 Set Global Paramet ers

Figure 5 Setup Global Parameters - Phone Ring Multicast and Port

Figure 5 shows the Phone Ring Multicast and Port number setting. This value will be the same as
that shown in Figure 1.

3.4.3 C-Soft Phone Control Buttons

Figure 6 C-Soft Phone Control Buttons Setup

Figure 6 shows a few of the basic C-Soft Phone Control buttons. Any button can be configured
for a task by Right-Clicking on the button, then using the UI Element Function pull down menu.
In this case, Phone – On/Offhook was selected. The Remote Phone Line Select tab shows that no
specific line was selected as the Phone asset. Instead Pool was selected. In the case of the IP-223,
Pool mode means that if both lines are setup as Phone Mode(PSTN or iDen System), the open
line will be selected for use when the console tries to connect. This is the same function as the
multi-line telephone. Also shown is an example of a few phone control buttons. Please refer to
the C-Soft manual for further details on the button configuration.

3.4.4 C-Soft Radio Line Ty pes:

To use the IP-223 iDen Radio interface in Direct Connect Mode, the line type will be the
standard radio type. As shown in Figure 2, each Function tone entry will have a Direct Connect
number association. Simply changing the Function Tone selection will steer the Direct Connect
dial string. The same can be said for Group Call and Call Alert.

3.5 Manual Connections

A DTMF keypad can also be used on the console to manually dial the DirectConnect and Phone
modes of the NI223. By adding a 16 key dtmf keypad to the console design in C-Soft this is
facilitated. One major difference between this keypad and the normal keypad is the addition of
the A,B,C, and D keys for advanced control of the Nextel phone.

3.5.1 A-Key, Alert

The ‘A’ key is used to send an Alert function over the iDen system. Using the standard dialing
keys, enter the ID of the radio to send the alert to and then press the A key. Typically, labeling
the A key as Alert is a good idea.

3.5.2 B-Key, Send

The B key is used as a send button in manually dialing a phone call. Take the phone line
offhook, dial the number, then press the B key to connect the call. Label this button as send in
the console design.

3.5.3 C-Key, Group Call

Enter the group number to be called followed by the C key. When
the PTT button is pressed, a group call will be completed. Label the
C key as Group.

3.5.4 D-Key, DirectConnect Call

Enter the direct connect number to connect to then the D key. When
the PTT button is pressed, a Direct Connect call will be completed.

3.6 Audio Alignment Procedure

3.6.1 Receive Audio Alignment

The standard Receive audio alignment procedures should be followed for the NI223 installation.
With AGC turned OFF, inject a 0dBm test tone into the IP-223 front end and measure the level
at the Receive audio test points for line 1 or 2. (TP13 or TP1) The level should be near, but
below 0dBm reference from the test point to ground (TP14, near TP13). This should result in
audio levels from the iDen Radio at –5dBm to –10dBm as shown in Figure 8. A meter can be
used if the unit is on the bench top, or if installed, the front panel VU meter can be used. To
access the VU meter Press and Hold the line button, then press the IC button three times. A
general talk test is still the best mechanism for ensuring a quality connection. The system can be
tested with a handset from the front panel as well. To purchase the handset, contact the Telex
Vega Sales department.

Figure 8 IP-223 Receive Audio Alignment Example

3.6.2 Transmit Audio Alignment

The Transmit audio (Audio IN) to the iDen Radio should not be overdriven. The levels to the
radio should be at or near -5dBm as measured at the IP-223 radio test point on the front of the

NI223 iDen Radio Interface 9

unit. The TX Pot on the front panel of the IP-223 will be near 9-12 o’clock depending on the
microphone source. Alternatively, the Software Gains may be adjusted to gain more granularity
in the pot setting to accommodate different microphones. Figure 9 shows an example Transmit
Gain setting. From here a simple talk test will result in good audio levels.
