vism Lapd Index

1.3.6.1.4.1.351.110.5.5.12.1.1.1

This is an index to vismLapdTable. This is derived from the following formula: index = 31 * (DS1# - 1) + DS0# where : DS1# - The T1/E1 line number in the range 1 - 8. DS0# - The DS0 channel number ranging from 1 to 24 for T1 and 1 to 31 for E1. ::= { vismLapdEntry 1 } SYNTAX INTEGER { pri(1), gr-303(2) } MAX-ACCESS read-create STATUS current DESCRIPTION This object indicates the type of the LAPD interface. When the user creates a LAPD entry this object need to be specified. After creation it cannot be modified. 'pri' - level of service provided by ISDN(Integrated Services Digital Network) that carries voice, data, other services with control and signaling information in D-channel. 'gr-303' - standard interfaces for integrated digital loop carrier systems. DEFVAL { pri } ::= { vismLapdEntry 2 } SYNTAX Integer32 (1..127) MAX-ACCESS read-create STATUS current DESCRIPTION The window size - maximum number of sequentially numbered I-frames that may be outstanding. DEFVAL { 7 } ::= { vismLapdEntry 3 } SYNTAX Integer32 (1..10) MAX-ACCESS read-create STATUS current DESCRIPTION The maximum number of retransmissions of a frame. DEFVAL { 3 } ::= { vismLapdEntry 4 } SYNTAX Integer32 (100..1023000) UNITS "milliseconds The maximum number of time in milliseconds to wait for acknowledgement for a transmit frame. This value should be less than vismLapdT203. For PRI, the range is 1000 ms to 1023000 ms. The default is 1000 ms. For GR-303, the range is 100 ms to 350 ms in increments of 50 ms. The default value is 150 ms. ::= { vismLapdEntry 5 } SYNTAX Integer32 (1000..1023000) UNITS "milliseconds The maximum time (in milliseconds) allowed without frames being exchanged. This value should be greater than vismLapdT200. For PRI, the range is 1000 to 1023000 and the default is 10000 ms. For GR-303, the range is 10000 to 300000 ms in increments of 10000 ms. The default is 30000 ms. ::= { vismLapdEntry 6 } SYNTAX INTEGER { ccitt(1), att5EssPRA(3), att4Ess(4), ntDMS100PRA(6), vn2or3(7), insNet(8), tr6MPC(9), tr6PBX(10), ausp(12), ni1(13), etsi(14), bc303TMC(15), bc303CSC(16), ntDMS250(17), bellcore(18), ni2(19) } MAX-ACCESS read-create STATUS current DESCRIPTION This object specifies what type of interface the LAPD stack will be used with. ccitt(1) : CCITT att5EssPRA(3) : AT&T 5ESS PRA att4Ess(4) : AT&T 4ESS ntDMS100PRA(6) : NT dms100 PRA vn2or3(7) : VN 2 or VN 3 insNet(8) : INS Net tr6MPC(9) : tr6 MPC tr6PBX(10) : tr6 PBX ausp(12) : Austel Primary ni1(13) : National ISDN-1 etsi(14) : ETSI bc303TMC(15) : Bellcorp tr303 tmc bc303CSC(16) : Bellcorp tr303 csc ntDMS250(17) : NT dms250 bellcore(18) : Bellcore ni2(19) : National ISDN-2 DEFVAL { ni2 } ::= { vismLapdEntry 7 } SYNTAX RowStatus MAX-ACCESS read-create STATUS current DESCRIPTION Row status allows users to create or delete a LAPD entry. 'createAndGo' - this option is use to create an entry in the table. Before a LAPD entry is created, the session manager should be set up(add a PRI backhaul session set, and session group between VISM and the call agent). Before creating a LAPD entry the entry in HDLC table will implicitly created first. If the DS0 has already been used then the request of creating a LAPD channel on the same DS0 on the same line will be rejected. After creating the LAPD entry the corresponding entry in vismLapdStatsTable will be implicitly created. 'active' - When an entry is created it becomes active. 'destroy' - Use this to delete an entry in this table. After implicitly deleting all the entries(if there is any) in vismLapdDlcEntry table for the specific D channel the entry in vismLapdEntry will be deleted, then the entry in vismLapdStatsTable will be implicitly deleted, followed by the deletion of the HDLC entry. ::= { vismLapdEntry 8 } SYNTAX INTEGER { network(1), user(2) } MAX-ACCESS read-create STATUS current DESCRIPTION This object specifies whether LAPD stack is on the user side or network side. This object can be set when the row is created. It cannot be modified for an existing row. DEFVAL { network } ::= { vismLapdEntry 9 } SYNTAX INTEGER { backhaul (1), lapdTrunking (2) } MAX-ACCESS read-only STATUS current DESCRIPTION This object indicates if the line is configured for Trunking or PRI Backhaul. This object is set to the appropriate type when the vismRudpSessionType (defined in CISCO-VISM-SESSION-MIB MIB) parameter in the vismRudpSessionCnfEntry(specify in the same MIB) table is set. The motivation to have similar such objects at two places is for convenience. ::= { vismLapdEntry 10 } -- vismLapdStatsTable SYNTAX SEQUENCE OF VismLapdStatsEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION This table contains statistics information for all LAPD (D channel Data Link) interfaces on VISM. ::= { vismLapdGrp 2 } SYNTAX VismLapdStatsEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION An entry in the LAPD Table.
