CISCO-VOICE-CAS-MODULE-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

cvcmABCDBitTemplateConfigTable  OBJECT-TYPE
    SYNTAX      SEQUENCE OF CvcmABCDBitTemplateConfigEntry
    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION
        "This table is used to configure templates
         on the module/card. These templates provide
         mapping information between the incoming CAS 
         ABCD signaling bit patterns and the outgoing 
         ABCD signaling bit patterns. The outgoing 
         bit patterns are derived from the incoming 
         bit patterns by applying a set of actions to
         each incoming bit.
         
         Thus, this table essentially contains 
         configuration information about CAS ABCD 
         signaling bits.

         The ABCD bit carries signaling information
         describing off-hook, on-hook event etc on a
         T1 or E1. The pattern representations
         differ in CAS variants on a T1 and E1.

         For example:
         On T1:
         E&M protocol ABCD seized is 1100
         On E1:
         CAS-R2 signaling ABCD seized is 0001

         This table is configured on a per module/ card 
         basis.

         Further, one can have multiple different actions
         performed on the different bits (A, B, C or D)
         consecutively for the same incoming ABCD bit 
         index. However, a given bit position can only 
         have one action being performed on it for a given
         incoming bit pattern.

         For example, for a given incoming bit index, 
         one can define the 'A' bit to be set to 0, the 'B'
         bit to be swapped with the 'C' bit, the 'C' bit to be 
         swapped with the 'B' bit and the 'D' bit to be inverted.
         Thus, using this table, the user can create a template
         with name (cvcmCasTemplateName) 'Template1' where for 
         incoming pattern (cvcmABCDIncomingPattern) '0000', 
         the action on the A bit (cvcmCasABitAction) is 
         'casBitSetToZero', the action on the B bit 
         (cvcmCasBBitAction) is 'casBitCBit', the action on the 
         C bit (cvcmCasCBitAction) is 'casBitBBit' and the action
         on the D bit (cvcmCasDBitAction) is 'casBitInvertBit'.
         This will create one entry in 'Template1' where the 
         resultant outgoing pattern (cvcmABCDOutgoingPattern)
         will be '0001'.
