Chapter 6. DTE Port Configuration

Protocol Options

Signaling Type (SIGNAL)

Set the signaling type for the DTE port to match the signaling type of the connected DTE device. Choices are none, FRF LMI, ANSI T1.617-D, and ITU-T Q.933-A. If none is chosen, the signaling state for the DTE port is always up.

T392

Set the timeout 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 formed by the FSU 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.

For example:

If N392=3 and N393=4, then if three errors occur within any four events the interface is determined inactive.

The status of the connection can be viewed in the Status menu under DTE Port Signaling State. The status will return to active once the threshold is no longer exceeded.

Guidelines for Configuring IP Addr, Subnet Mask, and Mng DLCI

If the attached router or FRAD is used to route SNMP/telnet frames to the FSU, set the Management DLCI to a unique value that identifies the virtual circuit between the router/FRAD and the FSU. The router/FRAD must also be configured to route the FSU IP address to this DLCI. The IP address and subnet mask for the DTE port must also be set.
