Procedures for Users Who Cannot Receive EC500
Calls on Their Cell Phones
■Perform Hardware Checks: If using DS1 loop back:
■If amphenol connector is being used:
—Verify that the loop back cable is properly
—If the connection is correct, the problem could be a bad cable. Replace the cable.
■If a D8W connector is being used:
—Verify that it is connected to Slot 8 of the Type 356A connector.
—If the above check is OK, the cause of the problem could be a bad cable. Replace the cable.
—The cause of the problem could also be that the 356A connector is bad. Replace the connector.
If using H.323 IP trunks for the loop back arrangement:
■Verify that the administration is as specified in the EC500 Release 3 Installation and Administration Guide’s Chapter 3, “Administration.”
■Busy out and release the two signalling groups associated with EC500 loopback.
■See maintenance documentation that can be obtained from the web site:

6.Check the COR of the inbound trunk in the loop back arrangement and verify that the trunk does not have calling restrictions, that it is not outward restricted, and that its Facility Restriction Level (FRL) is sufficient to access an external ISDN trunk facility. If any such problems are found, administer the right COR for that trunk.
7.Check the ARS Analysis table and make sure that there is an entry to route the cell phone number over an ISDN trunk on the switch.
If the problem cannot be corrected by following the above procedure(s) or those listed in Chapter 1, escalate the issue to an Avaya technician. In addition to the checks listed above, verify with the technician that the EC500 XMOBILE station is not restricted from receiving incoming calls.
