PERATION

Antistreaming Timer.

The Antistreaming Timer is controlled by RTS. If RTS

remains On long enough for a timeout to occur, the DDS transmitter sends DMI
[Data Mode Idle (all ones)]. The Antistreaming Timer is reset when RTS
transitions to the Off state. Choices are OFF, 10, 30, and 60.

DTE Port Parameters

The DTE Port Configuration screen (Figure 4- 12) allows setting the operating
parameters for the DTE ports.

Port Type.

The Port Type field displays the installed DTE interface which is either

V.35 or RS-232.

Port Rate.

Port Rate is determined by the Data Mode selection on the Network

Parameters. The values are 56K for DDS I and 64K for DDS II.

Port Format.

This field shows the data format for the DTE port which is always

synchronous.

DSR.

This field controls the behavior of the DSR signal during test modes. If

TEST>OFF is selected, DSR transitions to the Off state when a loop or BERT test
is active. Options are FORCED ON or TEST>OFF.

DCD.

This field controls the behavior of the DCD signal during an IDLE

condition. When Data Mode Idle codes are received, DCD transitions to Off if this
field is set to IDLE>OFF. This only applies to DDS I mode. Options are FORCED
ON or IDLE>OFF.

RTS.

If this field is set to NORMAL, the RTS signal controls the transmitter and

CTS output signal. If set to FORCED ON, the RTS input signal is set to On inside
the unit.
