Table 29: CTP Bundle Multiservice Audio Port Parameter Settings in CTPView

FieldFunctionYour Action

Port Description

Specifies a description for the port.

Enter a description of up to 64 alphanumeric characters. Do not use the following characters:

( ; ' " ) ]

I/F Type

Specifies the daughter card as the interface type.

Select DCARD.

Multi-Service Mode

Specifies that the bundle will run in audio mode.

Select Audio.

Audio Mode

Specifies whether this end of the circuit provides clocking or uses adaptive clocking.

If the CTP devices at both ends of the circuit are synchronized, you can configure both ends as Master.

Select one:

  • Master—This end of the circuit provides clocking.
  • Slave—This end of the circuit uses adaptive clocking.

Audio Channel

Specifies the channel or channels to enable.

Select one:

  • Channel 0—Enables only channel 0.
  • Dual Channel—Enables both channel 0 and channel 1.

Audio Sample Rate [ KHz ]

Specifies the sample rate for audio circuits in kilohertz. The sample rate determines the audio quality and the network bandwidth needed. Higher sample rates create an IP data flow that requires higher bandwidth.

8 KHz corresponds to standard toll quality voice.

48 KHz corresponds to CD quality audio.

Select one:

  • 8
  • 12
  • 16
  • 24
  • 32
  • 48

Audio μ-law Encoding

Enables or disables μ-law encoding. Standard audio code samples are 16 bits. If you enable μ-law encoding, the 16-bit samples are converted to 8 bits, consuming half of the bandwidth without significant audio degradation.

Select one:

  • DISABLED (16 bit samples)—Generates 16-bit audio samples.
  • ENABLED (8 bit samples)—Generates 8-bit audio samples.

Audio Squelch

Enables or disables the active squelch function on the circuit.

If enabled, specifies whether the squelch is active or inactive.

The squelch function gates local audio output when DSR-A (channel 0) or RTS-A (channel 1) inputs are active or inactive.

Select one:

  • DISABLED—Disables the active squelch function on the circuit (audio output is always enabled).
  • ENABLED/ACTIVE—Squelch input is grounded and analog output is disabled.
  • ENABLED/INACTIVE—No signal is applied to the squelch input. Input is open and analog output is possible.

Audio Channel 0 Output Level

Specifies the output level for channel 0.

Note the following information about the values:

  • 0—There is no output.
  • 128—Unity gain, which means there is no attenuation or gain.
  • 255—Gain is 2:1.

Enter a number from 0 through 255.

Audio Channel 1 Output Level

Specifies the output level for channel 1.

Note the following information about the values:

  • 0—There is no output.
  • 128—Unity gain, which means there is no attenuation or gain.
  • 255—Gain is 2:1.

Enter a number from 0 through 255.

Configuring Multiservice IRIG-B Mode Port Parameters for CTP Bundles (CTPView)

Before you begin:

  • Log in to the CTPView software at least at the Net_Admin level.
  • Connect the CTPView server to the CTP device for which you want to configure bundles.

To configure Multiservice IRIG-B mode port parameters using CTPView:

  1. In the side pane, select Bundle > Configuration.
  2. Run your mouse over the Display and Select an Existing Bundle bar.
  3. In the table of bundles, select the bundle that you want to modify.
  4. Under Bundle Options, configure the parameters as described in Table 30 and click Click to Submit Bundle AND Port Changes.

Table 30: CTP Bundle Multiservice IRIG-B Port Parameter Settings in CTPView

FieldFunctionYour Action

Port Description

Specifies a description for the port.

Enter a description of up to 64 alphanumeric characters. Do not use the following characters:

( ; ' " ) ]

I/F Type

Specifies the daughter card as the interface type.

Select DCARD.

Multi-Service Mode

Specifies that the bundle will run in IRIG-B mode.

Select IRIG-B.

IRIG-B Source

Specifies the direction of the circuit. Although the IP circuit connection through the network is full duplex, an IRIG-B circuit is a simplex application, and the interface can operate only in Rx or Tx mode and not both at the same time.

(Although the bundle is by default a full duplex IP connection, you can configure it for simplex to save network bandwidth.)

If the autonegotiation setting of the CTP Ethernet media and the far-end switch or router do not match, it is possible for the CTP Ethernet ports to be in a half-duplex state, although the duplex setting is not configurable and always assumed to be full-duplex on the CTP device. Starting with CTPOS Release 7.2, the half-duplex state at CTP network interface card (NIC) ports are acquired, regardless of the duplex setting configured on the far-end node. After the autonegotiation process is completed, if the CTP NIC cannot acquire full-duplex mode, then the interfaces are considered to be down and a log message is recorded in both the /var/log/messages directory and the syslog file stating that the interface is down due to a non-full duplex condition. You are prompted to verify the cable connection, speed, and duplex settings because the NIC link might be down.

Select one:

  • TX (signal enters CTP)—The end of the circuit that accepts IP packets, extracts the IRIG-B data codes, and transmits IRIG-B signaling output onto the cable.
  • RX (signal exits CTP)—The end of the circuit that recovers IRIG-B from the attached cable and generates IP packets toward the network.

IRIG-B Data Rate

Specifies the data rate on the IP connection.

Note the following about setting the IRIG rate:

  • Unless network bandwidth is at a premium, we do not recommend that you change this value from the default of 16,000 bps.
  • Although the IRIG information can be transported through the network at the minimum configured rate (1000 bps), a CTP bundle running at this rate is subject to high latency.

Enter a number from 1000 through 25,500 bps. The port speed must be a multiple of 100 bps.

Output High Volts Level

This option appears only if you set the direction of the port to Tx.

Specifies the high output level, which is measured in peak-to-peak voltage. This setting is based on a 50-ohm termination

Enter a number from 0.00 through 7.85 volts peak-to-peak.

Output Low Volts Level

This option appears only if you set the direction of the port to Tx.

Specifies the low output level, which is measured in peak-to-peak voltage. This setting is based on a 50-ohm termination.

Enter a number from 0.00 through 7.85 volts peak-to-peak.
