# Configuring 4WTO Port Parameters for CTP Bundles (CTPView)

For CTP bundles, you can configure a 4WTO daughter card installed on a serial interface module.

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.
- Disable the bundle before you modify the bundle options.

To configure port parameters for 4WTO daughter cards for CTP bundles 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, place a check mark in the Advanced Options show check box to display advanced parameters, and configure the parameters described in Table 1.

5. Click Click to Submit Bundle AND Port Changes.

Field | Function | Your Action
--- | --- | ---
Port Description | Specifies a description for the port. | Enter a description of up to 62 alphanumeric characters. Do not use the following characters:
    ( ; ' " ) ]
I/F Mode | Specifies that the interface is connected to a data communication equipment (DCE) device. | Select DCE.
I/F Type | Specifies the daughter card as the interface type. | Select DCARD.
Channel Options | Specifies the voice channel or channels to enable on the 4WTO daughter card. Each CTP port with the daughter card installed can support either one or two channels. | Select one: Channel 0—Enables only channel 0. Channel 1—Enables only channel 1. Dual Channel—Enables both channel 0 and channel 1.
Output Level | Specifies the output level for the 4WTO daughter card. Note the following information about the values: 0—Gain is 2:3 (signal is attenuated 33%, or 1.8 dB). 25—Unity gain, which means there is no attenuation or gain. 255—Gain is 4:1 (signal is amplified 400% or 6 dB). Intermediate values are derived with linear interpolation. The actual gain depends on the impedance of the attached device. | Enter a number from 0 through 255.
Input Level | Specifies the input level for the 4WTO daughter card. Note the following information about the values: 0—Setting the value to 0 attenuates the signal 33% (1.8 dB). 25—default and is the unity value (no attenuation or gain). 255—Setting the value to 255 amplifies the signal 400% (6 dB). Note the following information about the values: 0—Gain is 2:3 (signal is attenuated 33%, or 1.8 dB). 25—Unity gain, which means there is no attenuation or gain. 255—Gain is 4:1 (signal is amplified 400% or 6 dB). Intermediate values are derived with linear interpolation. The actual gain depends on the impedance of the attached device. | Enter a number from 0 through 255.
Port Speed |  | Enter a number from 0.00100 through 12288.00000 KHz.
Talk 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 1) or RTS-A (channel 0) inputs are active/inactive. | Select one: DISABLED—Disables the active squelch function on the circuit 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.
Clock Cfg | Specifies the type of clocking for the port. To prevent voice channels from generating occasional noise bursts caused by unsynchronized nodes, we recommend that you configure one end of the voice port (not both) for adaptive clocking or lock both ends to clock references. | Select one: Custom—Custom clocking configuration is used. Voice/IRIG-B Master End—This end of the circuit generates a clock signal and sends it to the remote end. Voice/IRIG-B Slave End—This end of the circuit receives the clock signal from the remote end. The clock slave uses its period to determine when to sample data and how to transmit data across the link.
