Clinical pharmacology

The CTI functionality allows the operator to connect an AN/PRC-150(C) to a Harris RF-6010 Tactical Network Access Hub via the radio’s PPP cable. This configuration provides the ability for base personnel to communicate with a deployed AN/PRC-150(C) or a network of deployed AN/PRC-150(C) radios via the base’s telephone system and the AN/PRC-150(C)’s 3G operating mode. In the following subparagraphs, the AN/PRC-150(C) connected to the RF-6010 shall be referred to as the basestation while a deployed CTI capable AN/PRC-150(C) shall be referred to as an outstation.

NOTE

This manual provides information on using the Harris AN/PRC-150(C) only. For detailed information on using the Harris RF-6010 or planning a CTI network, refer to the RF-6010 Tactical Network Access Hub User Manual.

3.19.29.1 Basestation Operations

The radio assumes the role of a CTI basestation when the RF-6010 is connected to the radio via its PPP cable and the RF-6010 initiates CTI communications with the radio. While a CTI phone call is in progress, the handset of the basestation will be disabled. When the handset is disabled, no audio will be heard, other than beeps indicating 3G connections. A hold-off tone will be produced if the operator attempts to key. Only the [CLR] button on the basestation’s KDU will function as described in Paragraph 3.19.29.4 while in a CTI call.

3.19.29.2 Connecting to the RF-6010

The AN/PRC-150(C) connects to the RF-6010 via its PPP cable. The baud rate of the PPP connection must be configured for 115.2 kbps. Should the PPP baud rate on the basestation be set to any other value, the KDU displays CTI GATEWAY INVALID PPP BAUD to indicate the configuration error. This message will appear upon power-up as well as power-upon entering the 3G radio mode from program or another radio mode.

3.19.29.3 Basestation Screens

The following subparagraphs provide information on basestation screens.

3.19.29.3.1 RF-6010 Initiated Call

When a call is initiated by the RF-6010, the following occurs:

•

Upon receiving a call request from the RF-6010, the KDU displays the standard 3G calling screen.

•

When the 3G radio mode circuit setup is successful, a tone is heard in the handsets of the outstation and the basestation radios. The KDU displays linked screen for the duration of the phone call, unless a higher priority status message such as CALL COMPLETE or WARNING: HIGH VSWR is displayed. See Figure 3-35.

•

Upon termination of the CTI call (by either the outstation operator or by the phone operator), TERMINATING PHONECALL is displayed briefly before the radio returns to scan.

SERVICE-3.19.29.3.2 Outstation Initiated Call

When a call is initiated by the outstation, the following occurs:

•

The standard 3G call receive screen is used during the link setup phase of the outstation phone call.

•

When the 3G radio mode circuit setup is successful, a tone is heard in the handsets of the outstation and the basestation radios. The KDU displays linked screen for the duration of the phone call, unless a higher priority status message such as CALL COMPLETE or WARNING: HIGH VSWR is displayed. See Figure 3-35.

•

After the 3G link has been established, the outstation will transfer the phone number. During the transfer of the phone number being called by the outstation, the basestation’s front panel will display the normal 3G link screen with the transfer information at the bottom of the KDU. See Figure 3-36.

•

Successful transfer of the phone number will be indicated by MESSAGE COMPLETE on the bottom of the KDU.

•

Upon receiving the phone number from the outstation, the basestation displays this message on the KDU.

Again, it will display the -TELEPHONY SERVICE- on the bottom of the KDU for the duration of the call, unless any other status messages are displayed on the screen. These status messages are displayed on the bottom line for three seconds.

•

After receiving the requested phone number from the outstation, it is possible that the CTI call is rejected for some reason. Reasons include basestation not being connected to the RF-6010, or the phone called is busy. When this occurs, the reason that the call is being rejected will be automatically transmitted to the outstation. After the reject reason has been transmitted, the basestation will wait for the outstation to terminate the link or for the link to time out, whichever occurs first.

•

Upon termination of the CTI call by either the outstation operator or by the phone operator, TERMINATING PHONECALL is displayed briefly before the radio returns to scan.

3.19.29.4 KDU Termination of CTI Calls

While a CTI call is in progress, a basestation operator is prevented from keying up the handset and from using the KDU with the exception of using the KDU to terminate the CTI call. To do this, perform the following procedure:

a. Press [CLR]. The radio will display TERMINATE PHONECALL?.

b. If YES is selected, the phone call will be terminated and the radio will return to scan. If NO is selected or if the [CLR] key is pressed, the phone call will continue unaffected. Select as appropriate.

3.19.29.5 CTI Automatic Override of Data

If the basestation is in a data communications with another radio or radios when a CTI call request originates from the RF-6010, the data communications will automatically be suspended. There is no need for a response from the operator.

NOTE

A request from the RF-6010 for a CTI call will not override a 3G voice call that is in progress.

3.19.29.6 Outstation Operations

The radio assumes the role of a CTI outstation if the PPP cable between the RF-6010 and the radio is disconnected or if the RF-6010 fails to initiate CTI communications with the radio.

The following subparagraphs cover outstation CTI operations.

3.19.29.6.1 Placing a Phone Call

A CTI call from an outstation allows an AN/PRC-150(C) radio to call a phone that is part of the phone system connected to the RF-6010. Perform the following procedure to place a CTI phone call:

a. Press [CALL].

b. Use the keys to select call type of PHONE.

c. Using the KDU keypad, enter the phone number to be called and press [ENT].

NOTE

The phone number is restricted to a length of 25 digits on the KDU. This length may be longer than the phone numbers used by the RF-6010.

Once the number has been entered at the outstation, the following occurs:

•

If the phone number is not formatted properly, the KDU will display INVALID PHONE NUMBER.

Pressing [CLR] will return the operator to Step c. If the number is valid, the KDU will display CALLING

<RADIO NAME>.

•

When the 3G radio mode circuit setup is successful, a tone is heard in the handsets of the outstation and the basestation radios, and the KDU displays the screen shown in Figure 3-37.

•

The outstation then proceeds to transmit the entered phone number to the basestation. See Figure 3-38.

•

If the outstation is configured to have CTI ringback enabled, a short three beep burst will be heard in the outstation handset followed by a period of silence. This pattern will repeat in the handset until the outstation operator keys the radio or the phone operator keys.

•

If for some reason the phone call is rejected by the basestation or by the RF-6010, a reject reason will be received by the outstation. The outstation will automatically terminate the CTI call and return to scanning with the reject reason displayed on the bottom of the KDU. (Refer to Table 3-11 for reject reasons.)

•

If no reject code is received, then the operator can key the handset and talk.

NOTE

There is no feedback provided to the outstation operator to indicate that the phone operator has answered their phone.

Even if CTI ringback is enabled, the ringback tones will continue to be generated until one of the operators keys. It is recommended that the phone operator be required to key upon answering their phone to ensure successful communications.

Perform the following procedure to terminate the CTI call:

d. Press [CLR]. TERMINATE PHONECALL is displayed on the KDU.

e. Use the keys to select YES and press [ENT]. TERMINATING PHONE CALL is briefly displayed, followed by CH### SCANNING.

3.19.29.6.2 Net Phone Call Operation

While not being capable of placing a net CTI call, the outstation can receive a net CTI call that was initiated by the basestation phone.

NOTE

If CTI ringback is enabled on the outstation, there will only be an audible indication (a short three beep burst) upon receiving a Net CTI Call. If CTI ringback is not enabled, there will be no indication of any kind of an incoming CTI Net Call.

NOTE

A CTI net call can only be performed from a phone using a net call phone number that is programmed into the radio using the RPA.

3.19.29.6.2.1 Broadcast CTI Net Call

When the basestation’s CTI net call type is set to broadcast, the outstation operator will not see a 3G call status screen. Instead, when the 3G radio mode circuit setup is successful, a tone is heard in the handsets of the outstation and the basestation radios. The KDU displays the screen in Figure 3-35.

If the outstation is configured to have CTI ringback enabled, a short three beep burst will be heard in the outstation handset followed by a period of silence. This pattern will repeat in the handset until either the outstation operator keys the radio or the phone operator keys. At this point, the operator can key the handset and talk.

Perform the following to leave a broadcast CTI call:

a. From the outstation, press [CLR]. LEAVE PHONECALL is displayed. If this is not done, the call will terminate when the base phone is placed back on its hook.

b. Use the keys to select YES and press [ENT]. LEAVING PHONECALL is briefly displayed, followed by CH ### SCANNING. If there were other outstations connected in the net CTI call they will not be affected by this. If this was the last outstation in the CTI net call, the call will be terminated.

3.19.29.6.2.2 Role Call CTI Net Call

When the basestation’s CTI net call type is set to role call, the outstation operator will not see the 3G call status screens while the radios set up the connection. When a response to the call is received from another net member, the text RESPONSE FROM and the name of the responding station will be displayed on the bottom line of the KDU.

A tone is heard in the handsets of the outstation and the basestation radios. The KDU displays the screen in Figure 3-35.

If the outstation is configured to have CTI ringback enabled, a short three beep burst will be heard in the outstation handset followed by a period of silence. This pattern will repeat in the handset until either the outstation operator keys the radio or the phone operator keys. At this point the operator can key the handset and talk.

Perform the following to leave a role call CTI net call:

a. From the outstation, press [CLR]. LEAVE PHONECALL is displayed. If this is not done, the call will terminate when the base phone is placed back on its hook.

b. Use the keys to select YES and press [ENT]. LEAVING PHONECALL is briefly displayed, followed by CH ### SCANNING. If there were other outstations connected in the net CTI call, they will not be affected by this. If this was the last outstation in the CTI net call, the call will be terminated.

While in a role call CTI net call, it is possible to view the stations that are participating in the phone call. Refer to Paragraph 3.19.20.

3.19.29.6.3 CTI Call Break-In

While a data transfer is actively being performed between two AN/PRC-150(C)s in 3G radio mode, the data transfer can be preempted to allow a CTI phone call to be made. This functionality is similar to voice call break-in described in Paragraph 3.19.22.

NOTE

It is not possible to preempt a 3G voice call for a CTI phone call.
