Figure 13 contains three panels. For the configuration in the left panel (CDP), the administrator
must set the preferred protocol to CDP in the CESID Assignment form; for the configuration in
the middle panel (STP), the administrator must set the preferred protocol to STP, and for the
configuration in the right panel, the preferred protocol is set to STP and CDP.
If a conflict is detected between the STP/RSTP and CDP data, a log is generated. Logs are
recorded for all device moves and CESID-related activity and alarms are raised when the
system identifies a device (DN) with a missing CESID, typically when a device moves to an
unknown location.
Teleworker devices
Emergency call routing in a Teleworker environment is supported with the use of the following
equipment only:

Mitel Line Interface Module (LIM)
For information about LIM configuration refer to the LIM Installation Guide. For information
