Chapter 6. DTE Port Configuration

Forced On

The CD lead is always on.

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 defines the number of errors required in a given event window, while N393 defines the number of polling events in each window.
