5 Set the Facility Data Link according to your Service Confirmation Letter.
Two Facility Data Link (FDL) protocols are available. You may select either protocol
listed, both protocols, or no protocol.
•
T1.403. Sends Performance Report Messages. The service provider can maintain a
continuous history of trunk performance. The service provider can also send test
messages to the trunk, if needed.
•
TR54016. Sends messages when it is queried by the central office. If the service
provider wants to know the status of a particular trunk, it will ask for it, and the Wave
Server will send the information.
•
T1.403 & TR54016
• None
This option is provided to allow the T-1 trunk to be tested and maintained by far-end
equipment, for example, by the T-1 service provider’s equipment.
Your trunk provisioning letter should include this information.
T-1 service providers try to guarantee the up time of the trunks they provide in two ways:
• They keep track of the physical layer errors in both directions, when possible, to
proactively identify problems
• They send commands from their end of the T-1 to automatically loop T-1 trunks for
error testing
You can view these messages in the trace log by using the Trace Monitor diagnostic applet
in the Remote Diagnostics Console.
If you are configuring FDL on a public network, refer to the T-1 service provider’s
provisioning letter for information about the type of FDL support the service provider
supports. If nothing is mentioned, select None.
If you are configuring FDL on a private network, you will typically select None. Since you
control both of the T-1 endpoints, you can monitor statistics at each end.
If one trunk endpoint is not a Wave Server, select either T1.403 or TTR54016 according to
what the management equipment supports on the non-Wave endpoint.
