Chapter 6. DTE Port Configuration

6-4 IQ Probe User Manual 61200214L1-20

Normal

The CD lead is off when the IQ Probe does not receive CD from the DSU/

CSU on the DCE port.

TC Clock Option (TC CLOCK OPT)

Normal

Clock for DTE's transmit data normal phase.

Inverted

Clock for DTE's transmit data inverted phase. May be used in high speed

circuits (>512 kbps) when the DTE's V.35 interface has high delay. This is

usually indicated by HDLC errors on the IQ Probe's DTE port.

Frame Relay Options (FR OPTS)

These selections apply to the signaling between the router or FRAD and

the IQ Probe DTE port.

T392

Set the timeout (in seconds) between polling intervals. This parameter

needs to be a few seconds longer than the T391 setting of the attached

frame relay device.

N392 and N393

These parameters define the error threshold for the UNI (user to network

interface) formed by the IQ Probe DTE port and the attached frame relay

device. If the error threshold is met, the signaling state status is changed

to down, which indicates a service-affecting condition. This condition is

cleared once N393 consecutive error-free events are received. N392 de-

fines the number of errors required in a given event window, while N393

defines the number of polling events in each window.
