On Sunday, September 21, 2003, a communications disaster recovery test will be conducted of SIAC’s Network. This test will involve all participants who access SIAC via a communication link. The purpose of the test is to assure that we have the ability to switch your communications access to our alternate facility.

The following disaster procedures will be followed:

For Leased Line connections with dual site capability, SIAC will switch primary connections to an alternate site.

For Leased Line connections with just Dial backup, SIAC will fail connections to an alternate site, which will invoke the dial back-up and re-establish a connection to SIAC.

For all Dial connections to SIAC, SIAC will ask participants to use the alternate site backup phone number.

For T1 (Mux Connections), arrangements will be made on an individual basis, to determine the designated ports to be used.

For Frame Relay connection with dual PVCs capability, SIAC will disable your PVC access.
