Chapter 5. Configuration Menu

Port Configuration (Port Config)

Port Configuration selects and configures the parameters associ- ated with any data port in the unit. For example, parameters for the Drop Port Interface (PBX) interface are set through this menu. The items that can be set depend on which option module is installed. The list of option ports will vary with the configuration.

The ESU 120e is designed so that any additional ports developed in the future will contain the appropriate menu selections to provide access by use of this menu item.

The Config menus for options ports are described in separate sec- tions of the manual supplied with the option card.

INTERFACE

This option sets the electrical interface for the Base

 

Nx56/64 port.

 

Choices: V.35, V.11 (X.21), RS530, V.36

 

 

TSO RATE

This sets the base rate of the interface. The actual

 

data rate depends on the number of DS0s assigned

 

to the Nx port.

 

Choices: 56K or 64K

 

 

TX CLK

Controls the clock used by the TSU 120e to accept

CNTRL

transmit (TX) data from the DTE. The default is

 

normal. If the interface cable is long, causing a

 

phase shift in the data, the clock can be selected as

 

Invert. This switches the phase of the clock which

 

should compensate for a long cable.

 

Choices: Normal, Invert
