Note: For information about updating CESIDs, see CESID Maintenance.
You must program a CESID for each DN in the network.
To program CESIDs
Class
of Service Options form
Enable "Display ANI/ISDN Calling Number Only".
Program the ARS for the ISDN trunks.
Assign the ISDN trunks in the Trunk Attributes form.
Put the trunks into a trunk group, using the Trunk Groups form.
Assign the Trunk Group to a route in the ARS Routes form, and designate the route as an Emergency route by selecting Emergency from the Route Type list.
Add an entry in the ARS Digits Dialed form for "911" (digits dialed 911, no digits to follow), and point this to this route.
Note: There are additional considerations if multiple emergency dialing strings are necessary for different geographic regions within a cluster. Emergency dialing strings must be COR restricted if the telephone set location is not served by the PSAP.
CESID
Assignment form
Assign a CESID number to each primary extension number. The MAC address of the Layer 2 switch port and
the Layer 2 switch port identifier are detected by the system when an
IP phone registers.
Note: You also have the option of manually assigning the MAC Address and port identifier to the Layer 2 switch ports in the L2 to CESID Mapping form. However, it is recommended that you allow the system to detect the address since this method is less prone to error.
CESID
Assignment Default form
Assign values for the CESID Assignment defaults.
L2 to CESID Mapping form
The "L2 Port MAC" field displays the MAC address of the Layer 2 switch port. The MAC address is detected by the system when an IP phone registers. You also can manually assign the L2 switch port MAC address during an Add operation, but not during an Edit operation.
The "L2 Port" field displays the identifier of the port. The port identifier is detected by the system when an IP phone registers. You can also manually assign the L2 switch port identifier during an Add operation, but not during an Edit operation.
Assign a CESID to each Layer 2 switch port.
To propagate CESID over IP trunks in a clustered environment, the IP trunks need to be in ARS route designated as an emergency route in the ARS Routes form.
CESIDs are modified in the CESID Assignment form.
Note: For IP devices that have automatic CESID updating enabled, the system updates the L2 to CESID Mapping table with the new CESID when the IP Phone registers at a known location and automatically updates the CESID in the CESID Assignment form.
To manually modify a CESID
In the CESID Assignment form, select the entry to modify, and click Change Member.
Enter the new CESID and/or CESID Comments, and click Save.
You can manually add, modify, or delete the CESID for a DN in the L2 to CESID Mapping table. We recommend that you do not manually enter information; however you may use this table to ensure that every port is assigned a CESID.
To add an entry to the L2 to CESID Mapping form
In the L2 to CESID Mapping form, click Add.
Enter the L2 Port MAC address, L2 Port number, and CESID.
Click Save.
To modify an L2 to CESID Mapping
In the L2 to CESID Mapping form, select an existing entry, and click Change.
Enter the new CESID, and click Save.
To delete an L2 to CESID Mapping
In the L2 to CESID Mapping form, select an existing entry, and click Delete.
Note: If a DN is deleted from the system (for example, through the 3300 System Administration Tool), the DN is automatically deleted from the CESID Assignment form; however, since the corresponding L2 to CESID Mapping may still be a valid mapping, the system does not delete any entries from the L2 to CESID Mapping table when a DN is deleted.
