4.1.2 Connectionless Port Termination Point
A Connectionless Port Termination Point (CPTP) is a potential port capability for connectionless
technologies. A CPTP is not a new object, but it is a logical entity of a piece of equipment and supports a
connectionless client layer. A CPTP is a grouping of potential FPs on the server layer. The FPs are the
clients of a CPTP connected using MFD.
A CPTP is created as a Physical Termination Point (PTP) if the port is an external port and if it does not
support encapsulation and link aggregation. CPTP is created as a Floating Termination Point (FTP) if the
port is an internal encapsulation port and if it supports encapsulation and link aggregation. A CPTP on an
MFD can be either a PTP or an FTP.
ConnectionlessPort is a boolean layered parameter that identifies termination points (TPs) as CPTPs at
connectionless layers; for example, Ethernet. For an Ethernet client layer, a CPTP corresponds to an IEEE
bridge port, which can either be a UNI or an NNI.
The role played by CPTP for its connectionless client layer is stored in the “PortTPRoleState” layered
parameter, which is associated to the PTP/FTP object. The “PortTPRoleState” parameter can assume the
following values:

following values:
• unassigned CPTP—The initial role of a CPTP is unassigned. If CPTPs are automatically
created, they are created as unassigned CPTPs when the equipment that supports the port is
plugged into the NE. In this role, the CPTP cannot carry any traffic.
plugged into the NE. In this role, the CPTP cannot carry any traffic.
• assigned CPTP—An unassigned CPTP becomes an assigned CPTP when it is associated to
an MFD through a management operation. In this role, the CPTP cannot carry any traffic
because the MFD is not associated to an FD.
because the MFD is not associated to an FD.
• fdInternal CPTP—An assigned CPTP becomes an fdInternal CPTP when the MFD is
associated to an FD. An unassigned CPTP becomes an fdInternal CPTP when it is assigned
to an MFD that is already associated to an FD. In this role, the potential client FPs of the
CPTP can be used as internal points of the route of a Flow Domain Fragment (FDFr) and can
carry traffic.

CPTP can be used as internal points of the route of a Flow Domain Fragment (FDFr) and can

• fdEdge CPTP—An fdEdge CPTP is the same as an fdInternal CPTP. In this role, the CPTP
acts as an edge in the FD.
