P-Context-Count Sample Clauses

P-Context-Count. The P-Context-Count parameter determines the number of contexts to be maintained for the data compression protocol. Each context represents a logical connection between the DCP peers. Each context shall contain an X3.241 history buffer and additional information for error detection and synchronization procedures. The DCP peers use error detection and synchronization procedures to ensure that both the encoder and decoder copies of each history buffer are identical. Setting P-Context-Count to the value “0” indicates that the compression is to be on a connectionless basis. In this case, a single context shall be used and the history buffer shall be cleared at the beginning of every DCP data PDU. The sender shall set the R-A bit to “1” on all outgoing DCP data PDUs. When P-Context-Count is set to the value “1”, a single context shall be maintained by each of the DCP peers. When P-Context-Count is greater than “1”, P-Context-Count separate contexts shall be maintained by the receiver. The sender peer may use up to P-Context-Count separate contexts. The DCCI field shall be included on all DCP data PDUs in both directions in this case. Its size shall be determined by the P-Context-Count as described in Section A.2.1.7.
