T1 Compatibility Options

The version of the hsip_init utility shipped with the SunHSI software has options that enable you to invert data and clock signals to accommodate the requirements of T1 or CEPT transmission equipment. The hsip_init parameters that allow for inversion are:

■txd – transmit data signal

■rxd – receive data signal

■txc – transmit clock signal

■rxc – receive clock signal

The effect of the default settings for all of these parameters is that SunHSI software does not invert the data or clock signal controlled by the parameter. To invert a signal, you specify a setting of the form param-name=-paramname, for example, txc=-txc.

As an example, suppose you want to invert the transmit and receive data signals on the first SunHSI/U port (port 0) on the second SunHSI/U adapter in your system. To do so, enter the following command:

#hsip_init hihp4 txd=-txd rxd=-rxd

To invert both clock and data signals, enter:

#hsip_init hihp4 txd=-txd rxd=-rxd txc=-txc rxc=-rxc

Appendix C discusses the background and requirements for these inverted settings.

Operating Modes Options

This section describes the operating modes that you can set with the hsip_init utility.

The SunHSI software operates in two main operating modes, the high-level data link control (HDLC) mode and the IBM (SDLC) mode. The HDLC mode always operates in a full-duplex, point-to-point fashion. While the IBM mode defaults to a full-duplex, point-to-point, operation.
