This topic describes how to configure port parameters for serial interfaces.
Before you begin:
To configure serial port parameters for CTP bundles using the CTP Menu:
If you select an active bundle, you are prompted to disable the bundle before configuring it.
Table 1: CTP Bundle Serial Port Parameter Settings in the CTP Menu
Field | Function | Your Action |
---|---|---|
Port descriptor text | Specifies a description for the port. | Enter a description of up to 62 alphanumeric characters. Do not use the following characters: ( ; ' " ) ] |
Interface | Displays the menu used to configure the interface type, mode, and encoding. | Select 2) Interface. |
Type | Specifies the electrical standard used on the serial interface. | Select one:
|
Mode | Specifies that the interface is connected to a data communication equipment (DCE) device or to a data terminal equipment (DTE) device. | Select one:
|
Encoding | Specifies the serial encoding method used on this bundle. | Select one:
|
Enter Synthesized port rate (KHz) | 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:
The port speed also varies depending on hardware:
| Enter a number from 0.00100 through 12288.00000 KHz. |
Enable adaptive clocking? | Specifies whether adaptive clocking is enabled for this circuit. If both end nodes are not locked to a clock reference, we recommend that you enable one end (not both) for adaptive clocking Appears only if you select ISOCH, CDI, MSTAR, TRANS, or TDM encoding. | Specify y (yes) or n (no). |
Initialize adaptive clocking parameters? y[n]: y | If you enabled adaptive clocking, specifies whether or not to initialize adaptive clocking parameters to their default values, which depend on port speed, packet size, and buffering parameters set on the bundle. We recommend the following settings:
| Specify y (yes) or n (no). |
TDC Clk/Data on port N+1 | This option is used for TDM/TDC operation. See Configuring the High-Speed CTP Bundle for TDM/TDC Operation (CTP Menu). | |
TDM rates | This option is used for TDM/TDC operation. See Configuring the High-Speed CTP Bundle for TDM/TDC Operation (CTP Menu). |
