152 Introduction
Introduction
This chapter describes how to configure and monitor the 3086 serial interface, generic frame relay, and the
FRS system. There is also a description of each section.
Serial Interface
The serial interface configuration menus allow the user to configure the serial interface for HDLC based con-
nections. Configurations are available for the web interface and the CLI interface. Both will be discussed in the
following sections.
Variables
The following variables are configurable on the 3086 software:
Clock
Options:
• Internal
• External
Function: The clock setting for the serial interface will determine the source of timing for the serial interface.
This will not set the source of timing for the DSL link and the timing derived from this interface can not be
used to driver the DSL interface
rxClkInv/txClkInv
Options:
• Inverted
• Normal
Function: The clock invert functions could be used to invert the clocks that are used on the serial interface. It
is not recommended to set these parameters unless requested by Patton Electronics’ technical support.
Speed
Options:
• Any n x 64K speed. Speed should be entered as the rate, i.e. “512” for 512Kbps or “2048” for 2.048 Mbps
Function: Defines the generated speed for internal clock mode operation or the clock that will be received in
external clock mode operation
txSamplePoint
Options:
• ExtClk
• TxClk
