If the disconnection message is:<br />
“Disconnect Layer 2”<br />
the cause of the disconnection should be at the logical level.<br />
The typical situation for this disconnection message is the<br />
incorrect configuration of the TEI management of the instrument.<br />
This value is set in the CONFIGURATION page (see Chapter 7)<br />
before connecting with the access and must comply with the<br />
setting of the tested access.<br />
In case of point-point access, the TEI must be set in fixed mo<strong>de</strong><br />
with typical value zero (0). For point-multipoint access, the TEI<br />
must be set in automatic mo<strong>de</strong>.<br />
! Two or more terminals with the same TEI value<br />
cannot exist on the same access. In case of<br />
AUTOMATIC TEI, this is checked by the network. In<br />
case of fixed TEI, the operator must check that<br />
settings are correct.<br />
If the instrument displays the following message:<br />
“Disconnect Layer 3”<br />
the cause refers to the compatibility between the configuration of<br />
the local user and of the remote user, or in the service<br />
management capacity of either the user terminal or the network<br />
(services not implemented, non transparent capabilities with<br />
interworking).<br />
