This and LMI (Rev 1) format are described under "StatusExchanges" on page 20-12.Status ExchangesEach status exchange line contains (at the end) a pair of 3-digit numbers that are thenext and current sequence numbers. The types of status exchange will be one of these:l Full Status Enquiries, which are sent by the frame relay DTE (i.e., the Smart-Switch 1800).l Full Status Responses, which help the DTE learn which DLCIs are available forsending/receiving data. The frame relay DCE (switch) should report a DLCI asactive only when it has a path through the frame relay network. The status of aDLCI will be reported as N (new) or A (active). A DLCI is reported as new ifthis is the first time it is being reported to the DTE. A DLCI reported as activewill (if not already done) transition the frame relay DLCI on the Virtual Con-nections Display ([C], [C] from the Main Menu) to Data_trans and the port PortStatus Display ([C], [B] from the Main Menu) to Operational.16:23:58:00 R 0016 D (0008) 030851816780013116:23:59:10 R 0016 D (0008) 03085181678003310000 LIV S tatus Enqu iry 135/13416:24:18:00 R 0016 F (0008) 030851816780013116:23:58:00 R 0016 F (0008) 030851816780013116:23:58:00 R 0016 F (0008) 030851816780033116:23:58:00 R 0016 B (0008) 03085181678003310000 Full Statu s En quiry 136/13516:23:58:00 R 0016 B (0008) 030851816780033116:23:58:00 R 0016 B (0008) 030851816780013116:23:58:00 R 0016 B (0008) 03085181678001310000 Full Statu s 136/13616:24:18:30 R 0016 D (0008) 030851816780013116:24:18:40 R 0016 D (0008) 030851816780033116:23:58:00 R 0016 F (0008) 030851816780013116:23:58:00 R 0016 F (0008) 030851816780033116:24:02:00 R 0016 D (0008) 030851816780033116:24:02:20 R 0016 D (0008) 03085181678001310000 LI V S tatus 135/13516:23:58:00 R 0016 B (0008) 030851816780013116:23:58:00 R 0016 B (0008) 0308518167800331
