yes,data link layer finalize and frame a packet as frame is a series of bits that units a data.........
Telegrams are sent in data packets. Bits packet frame segment data mean data packet and they belongs to Data link layer. Bye.
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".

Theoretically Data Link Layer puts packet into frame by adding header and tail to the packet but how is it possible when you take into consideration CCSDS packet definition:"A packet is a block of data with length that can vary between successive packets, ranging from 7 to 65,542 bytes, including the packet header.Packetized data are transmitted via frames, which are fixed-length data blocks. The size of a frame, including frame header and control information, can range up to 2048 bytes."According to this, frame is smaller than packet, so how can you put packet into frame??
Different textbooks may give you different answers to this question. In several I've seen, the "packet" is complete in the data link layer (layer 2) and is known as a 'frame' in the physical layer (layer 1). Others may indicate a packet is the result of the physical layer (layer 1). In other descriptions the terms packet and frame are interchanged in the layer 1 and 2 of the OSI model.
It depends on which textbook you are reading; some textbooks state that the frame is constructed in the data link layer (layer 2) and transmitted out the physical layer as a packet. Some other textbooks will say that the packet is created in layer 2 and transmitted out the physical layer as a frame.
The PDU at the Network layer is referred to as a packet. A PDU at the Data Link Layer is referred to as a frame.

The trailer protocol is a link-layer encapsulation method that rearranges the data contents of packets sent on the physical network. by : Umesh The trailer indicates where a frame ends. It, along with the header, encapsulates a packet, making it a frame. by: eSeriate
