Chapter 5. Configuration Menu

Port Configuration (Port Config)

Port Configuration selects and configures the parameters asso- ciated with any data port in the unit. For example, parameters for the DSX-1 (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 configura- tion.

The TSU 120 is designed so that any additional ports devel- oped 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 sections of the manual supplied with the option card.

0.1 Nx56/64 Port Configuration (Port Config) Menu Items

Description

 

 

DS0 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, 64K

 

 

TX CLK CNTRL

Controls the clock used by the TSU 120 to

 

accept 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
