vism Lapd Trunk Group Table

1.3.6.1.4.1.351.150.23.1.1.1

This table defines attributes used to set up a Trunked LAPD (Link Access Procedure on the D-channel) connection over RUDP between 2 VISM's to transport PRI D channel information. Such a Trunked connection over RUDP can only be created if the D-channel has already not been configured for PRI Backhaul. The object vismLapdTrunkType in vismLapdTable indicate PRI Backhaul or Trunking is configured, also an entry will be created for each D channel. PRI Backhaul and PRI Trunking can co-exist on the same card but not on the same line, a line (DS1) is associated with a LAPD RUDP through vismLapdTrunkRudpIndex. ::= { vismLapdTrunkGrp 1 } SYNTAX VismLapdTrunkGrpEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION An entry in the vismLapdTrunkGrpTable. INDEX { vismLapdTrunkNum } ::= { vismLapdTrunkGrpTable 1 } VismLapdTrunkGrpEntry ::= SEQUENCE { vismLapdTrunkNum Integer32, vismLapdTrunkState INTEGER, vismLapdTrunkRudpIndex Integer32, vismLapdTrunkRowStatus RowStatus } SYNTAX Integer32(0..2147483647) MAX-ACCESS not-accessible STATUS current DESCRIPTION This is the index of vismLapdTrunkGrpTable. ::= { vismLapdTrunkGrpEntry 1 } SYNTAX INTEGER { oos (1), is (2), unknown (3) } MAX-ACCESS read-only STATUS current DESCRIPTION 'oos' - Out of service state. The LAPD Trunk state is independent of the RUDP session state in the sense that the LAPD state could be 'oos' while the RUDP session state is 'is' and vice versa. 'is' - In service state. 'unknown' - This is the state other than the above states. If the communication is lost between the 2 VISM's, the state of this connection becomes 'oos'. ::= { vismLapdTrunkGrpEntry 2 } SYNTAX Integer32(0..2147483647) MAX-ACCESS read-create STATUS current DESCRIPTION All LAPD Trunk connections are over RUDP. Each RUDP connection is characterized by a set of negotiable and non-negotiable parameters. These parameters are in vismRudpSessionCnfEntry(defined in CISCO-VISM-SESSION-MIB MIB) table. This object is an index into that table. Before creating an entry in this table the corresponding RUDP session entry must be created in the vismRudpSessionCnfEntry table with the vismRudpSessionType(defined in the same MIB) as LAPD Trunking. The RUDP session cannot be deleted if the corresponding LAPD Trunk still exist. The LAPD Trunk needs to be deleted before deleting RUDP session as specified in CISCO-VISM-SESSION-MIB. ::= { vismLapdTrunkGrpEntry 3 } SYNTAX RowStatus MAX-ACCESS read-create STATUS current DESCRIPTION This variable allows the user to add or delete the entry for this table. 'createAndGo': Use this to add a LAPD Trunk connection in this table. The vismLapdTrunkRudpIndex for this corresponding entry has to be specified also. 'active': This value is returned, once the row is created. 'destroy': Use this to delete a LAPD Trunk connection from this table. ::= { vismLapdTrunkGrpEntry 4 } -- LAPD configuration table. SYNTAX SEQUENCE OF VismLapdEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION This table is used for maintaining the configuration of the LAPD channel on VISM. ::= { vismLapdGrp 1 } SYNTAX VismLapdEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION An entry for vismLapdTable.
