WAN Serial Port Configuration

The IPLink Series routers use a sync.-serial interface (X.21, V.35) or a T1/E1 interface for connection to stan- dard WAN services. Below are the configuration options for the WAN interface.

Serial Interface

The serial interface configuration menus allow the user to configure the serial interface for HDLC based con- nections.

Variables

The following table lists variables that are configurable on the IPLink’s software:

Variable	Options	Function
Clock Mode	Internal	The clock setting for the serial interface will determine the
		source of timing for the serial interface only.
	External
RX Clock Invert /	Inverted	The clock invert functions could be used to invert the clocks
TX Clock Invert		that are used on the serial interface. It is not recommended to
		change this parameter unless requested by Patton Electron-
	Normal
		ics’ technical support. Keep at default.
Serial Speed	Any n x 64 kbps speed.	Defines the generated speed for internal clock mode opera-
	Speed should be enter-	tion or the clock that will be received in external clock mode
	ed as the rate, i.e. 512	operation.
	for 512 kbps or 2048
	for 2.048 Mbps
TX Data Sample-	Ext Clk	When the unit is running in internal clock mode, the setting of
Point		TX Data SamplePoint will indicate to the system which clock
		to use to sample the in coming data. Some systems require
	Tx Clk
		that the data be sampled on one clock or another. This is
		also useful when tail circuits are being created.
		When running in the external clock mode this should be set to
		Ext Clk.
