TSU ACE User Manual Chapter 5 Config Menu

DTE TX CLK

Controls the clock used by the TSU ACE to accept the transmit (TX) data from the

DTE. Most applications will allow for this to be set to

NTERNAL

. If the interface

cable is long (causing a phase shift in the data) the clock can be selected as

-I

(Internal/Inverted - the factory default setting). This switches the phase of the clock

which should compensate for a long cable.

The

UTO

setting allows the TSU ACE to automatically detect the delay from the

DTE device to the TSU ACE and set the proper phase of the clock. This feature

automatically selects between the

NTERNAL

and I

-I

settings. If the DTE

provides a clock with TX data, the clock selection is set to

XTERNAL

. The TSU ACE

depends on an externally supplied clock to accept the TX data.

Choices: INT-INV, INTERNAL, EXTERNAL, AUTO

START CHAN

Sets the starting channel for the T1 stream. This setting must be consistent with the

carrier if using a public network.

Choices: 01 through 24

# OF CHAN

Sets the number of DS0s (channels) to be used. The corresponding DTE rate will be

this number times 56K or 64K, depending on

1)R

ATE

56/64.

Choices: 01 through 24

DATA

Controls the inversion of DTE data. This inversion can be useful when operating

with an HDLC protocol. Often used as a means to ensure ones (1s) density.

TSU ACEs on both ends must have identical option settings.

Choices: NORMAL, INVERT

CTS

Clear To Send - signal sent from the receiving station to the transmitting station that

indicates it is ready to accept data

Choices: FORCE ON, NORMAL (see Table 5-2 on page 42)

DCD

Data Carrier Detect - Indicates to the DTE when a valid signal is being received at

the Network Interface.

Choices: FORCE ON, NORMAL (see Table 5-2)

DSR

Data Set Ready - Indicates to the DTE when the DCE is turned O

and ready for

operations.

Choices: FORCE ON, NORMAL (see Table 5-2)
