Configuring Internal or External Clocking

Solstice X.25 supports the following clocking alternatives:

• Transmit clock and receive clock are both external. This is the situation in which clocking is provided by a synchronous modem or modem eliminator.

• Transmit clock is internal; receive clock is external. On the machine that is to supply clocking, set the Tx Clock parameter to the bit rate you want in the Link Editor in x25tool.

You can only use an IPC/IPX in situations where clocking is external, that is, where the remote (non-IPC/IPX side) supplies both the transmit and receive clocks.
