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.

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 as described in Table 21.

  5. Click Click to Submit Bundle AND Port Changes.

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 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.

When you change the encoding method, the clocking configuration changes to the default configuration for the encoding method that you select.

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. CDI encoding provides a speed of up to 4608 KBps.
  • 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).
  • TRANS8—Extension of the TRANS encoding. Compared with TRANS encoding, which sends four signals in each direction, with TRANS8 encoding, bandwidth is doubled and eight signals can be sampled and transported. This allows signals to be sent from additional interfaces that were not supported in TRANS encoding. </para>

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.

You can install the following optional daughter cards on a serial interface:

  • T1/E1 (CTP1000 and CTP2000 series)
  • 4WTO (CTP1000 and CTP2000 series)
  • IRIG-B (CTP2000 series only)
  • Multiservice Daughter Cards (CTP 2000 and CTP150 series)

Select one:

  • EIA-530
  • EIA-530A
  • RS-232
  • V.35
  • DCARD
  • 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 circuits, the port speed is limited to 4608 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 12880.00000 KHz.
