ESDI/AML states

An ESDI/AML port may be in one of the states shown in the

following table.

MSDL/AML states

The layer 2 and layer 7 states of an MSDL/AML port are

reported separately by the STAT AML command.

Layer 2 can be disabled, released, or established. Layer 7 can

be disabled or active. Refer to the SL-1 Input/Output Guide

(NTP 553-3001-400) for a more complete description.

The messages listed in “ESDA error messages” on

page 17-11 and “CSA error messages” on page 17-12 include

additional information, where

n = AML number. See prompt ADAN in Overlay 17.

t = The system time.

x = The reason that the error code was issued.

Only a partial list of errors (those applicable to Meridian

Mail) is included here. For a complete list of possible error

State Description

Disabled The ESDI/AML port has been disabled by the

DIS ESDI/AML command.

Enabled The ESDI/AML port has been enabled, but the

link layer has not been set up by the CON

ESDI/AML command. The ESDI/AML port

must be in the enabled state to perform the

self-test.

Connected The ESDI/AML layer (LAPB protocol) is set up

(see CON ESDI/AML command) and the port

is ready to send and receive messages.

Auto Setup The ESDI/AML is attempting to set up the

LAPB layer for AML applications. This state

occurs during automatic recovery of the AML

or while the ACMS command is in progress.
