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