IDSL/Channel Rate

Write security: 2; Read security: 5

Determines the rate at which data is transferred over the IDSL link.

Possible rates are 64K, 128K, and 144K, or Auto. When Auto is select-

ed, the Express L128FP will determine the rate to use.

Read security: 5

This contains the number of Near-End-Block-Errors (NEBEs) that

have been detected by the Express L128FP's IDSL circuitry. Continu-

ous errors can indicate a line problem, but a burst at one time is nor-

mal.

Read security: 5

This contains the number of Far-End-Block-Errors (FEBEs) that have

been detected by the IDSL circuitry on the other end of the link. Con-

tinuous errors can indicate a line problem, but a burst at one time is

normal.

»» WAN/L2 Protocol

Write security: 3, Read security: 5

This parameter specifies the layer 2 data link layer transport used.

When selected as PPP, the Express L128FP will negotiate PPP over the

IDSL interface. This is used mainly for campus wiring applications.

Parameters for controlling the PPP negotiation are in the Configura-

tion/PPP Profile menu. Frame Relay should be selected when the

Express L128FP is connected to a Frame Relay switch. The Configu-

ration/WAN/Frame Relay menu is used for controlling the Frame Re-

lay parameters. When

(def) is selected, the Express L128FP

Auto Detect

will look at the incoming packets in order to determine what layer 2

protocol to use.
