Investigate tests in the order presented below. Clearing Error Codes associated with the one

Sanity Handshake Test (#106)
This test checks the ability of a PN’s Maintenance circuit pack’s to respond to queries. A
message is sent to the PN’s Maintenance circuit pack which then sends a message back. If the
response message is received, then the Maintenance circuit pack is queried for the PN cabinet
type (valid PN cabinet types are single carrier and multicarrier cabinets). The Maintenance
circuit pack reads pins on the backplane of carrier A that identify the type of cabinet and report
this information. If a valid cabinet type is returned, then the test passes.
