How are window and packet size handled in local acknowledgment?
A. First, attempt to negotiate a consistent packet size for the call. If you cannot do so (one reason being that packet size negotiation is disabled) and local acknowledgment is enabled, then handle segmentation and reassembly for the circuit according to the X.25 recommendations. In the example below, serial 1 is configured for 128 and serial 0 is configured for 256: 3d22h: Serial1: X.25 I D1 Data (131) 8 lci 1024 M PS 5 PR 4 !— Two packets of 128 incoming. 3d22h: Serial1: X.25 I D1 Data (131) 8 lci 1024 M PS 6 PR 4 3d22h: Serial0: X.25 O D1 Data (259) 8 lci 1024 M PS 5 PR 4 !— One packet of 256 outgoing on other interface.
