The value of tmnxCcagPathCcType is used as a third index into
the tmnxCcagPathCcTable. Along with tmnxCcagId and tmnxCcagPathId,
it uniquely identifies a cross connection type on a specific path
in a particular CCAG. The types are:
sapsap (1): the cross connection is between two saps, where both
services are access.
sapnet (2): the cross connection is between a sap and a network
service.
netsap (3): the cross connection is between a network and a sap
service.
