# Configuring Serial Port Parameters for CTP Bundles (CTPView)

This topic describes how to configure port parameters for serial interfaces.

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 serial port parameters 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 Port Options configure the parameters described in Table 1.

5. Click Click to Submit Bundle AND Port Changes.

Table 1: CTP Bundle Serial Port Parameter Settings in CTPView

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 or to a data terminal equipment (DTE) device. | Select one: DCE—The interface is connected to a DCE device. DTE—The interface is connected to a DTE device.
Serial Encoding | Specifies the serial encoding method used on this bundle. | Select one: NRZ—Nonreturn to zero (NRZ) line encoding. ISOCH—Isochronous encoding. Isochronous encoding does not provide or embed the clock in the data. CDI—Conditioned diphase. Conditioned diphase encoding recovers and embeds the clock in the data signal. MSTAR—MilStar encoding. TRANS—Transparent encoding. See Configuring Transparent Encoding for CTP Bundles (CTPView) TDM—Additional data is interleaved with the port’s serial data. This option is used on TDM/TDC high-speed ports and is available only on even numbered ports on a CTP 2000 serial module. See Configuring the High-Speed CTP Bundle for TDM/TDC Operation (CTPView).
TDM Function | This option is used only for TDM/TDC operation. See Configuring the High-Speed CTP Bundle for TDM/TDC Operation (CTPView). |
TDM Rate | This option is used only for TDM/TDC operation. See Configuring the High-Speed CTP Bundle for TDM/TDC Operation (CTPView). |
I/F Type | Specifies the electrical standard used on the serial interface. | Select one: EIA-530 EIA-530A RS-232 V.35 OFF—Do not set the interface type to OFF.
Port Speed | Specifies the speed of the port. In networks without bandwidth constraints, we recommend a multiple of 10. The port speed recommendations vary according to encoding type: For transparent mode circuits, the port speed is the sample rate for user data. Therefore, port rate should be a multiple of the user data rate. For CDI or ISOCH circuits, the port speed is limited to 1024 Kbps. The port speed also varies depending on hardware: CTP2000 devices cannot have an aggregate port rate greater than 114.688 Mbps. | Enter a number from 0.00100 through 12288.00000 KHz.
