6.1.10. Data Selection Previous topic Parent topic Child topic Next topic

The data selection programs offer the operators of systems with call detail recording the capability of adjusting the data output of certain connections according to internal company requirements concerning the existing output capabilities (devices).
These then continue the processing of data records that were recorded by the data recording function and that were entered into memory especially reserved for this purpose at the end of the connection or section.

Selection sequence:

The selection processes each connection block or the standard data record that results from it. This is also true for standard data records that result from connection attempts (for example, station is busy in the trunk).
The basis of the selection process is the selection field, which is divided into 4 so-called selection groups (see AMO SELG).
Each selection group corresponds to an independent output unit with definable device allocation, where the outputs for "Display at attendant console" (or several attendant consoles) or each HD file are considered as one device.

POOL_PART
RES_OUT_WO_QUE
DEV_BAS
DEV_RES
BLOC_BAS
BLOC_RES
SEL_GR_STATE
SEL_TAB
The following parameters are allocated to each of these selection groups.
  • POOL_PART
    Number of reserved elements (queue entries) in the CDB pool
  • RES_OUT_WO_QUE
    Mode of operation for the reserve output
  • DEV_BAS
    Device indicator for basic operation
  • BLOC_BAS
    Number of data records per output procedure (basic)
  • DEV_RES
    Device indicator for reserve operation
  • BLOC_RES
    Number of data records per output procedure (reserve)
  • SEL_GR_STATE
    Operating state of a selection group
  • SEL_TAB
    Field of 8 selection tables
    Each selection group (1-4) taken into service compares the connection characteristics of the standard data record with the customer-specific characteristics given in its 8 selection tables. If a connection characteristic within a selection group applies, the standard data record is processed by the next selection group, regardless of the decision (output/no output). Multiple outputs (to the same device) are thereby eliminated even if overlapping characteristics are entered.
    It is possible to make multiple outputs (parallel outputs) of a standard data record to different devices if there are additional selection groups with the same characteristic combination in the selection tables.
    Selection table
    A selection table contains 13 fields.

    Elements:
  • OUT_IND: output indications. Consists of the fields FORM_BAS, FORM_RES, CALC_LIST, DEST_LIMIT. The CALC_LIST field contains the new tariff group number, which is used during the charge calculation.
    Mode: DA_M_CGS_TA_OUT_IND_STR
  • LIMIT_CHARGES: limiting value for call charge units; output occurs if this value is exceeded.
    Mode: DA_M_CONN_CHRG_UNIT_RNG
  • LIMIT_TIME: limiting value for the duration of the connection; output occurs if this value is exceeded.
    Mode: DA_M_CG_TIME_STR
  • MEMB_ROUT_CODE: routing code
    Mode: DA_M_CGS_MEMB_ROUT_ARY
  • MEMB_SERV_IND: service with which output occurs (network type, transmission speed)
    Mode: DA_M_CGS_SERV_IND_PST
  • MEMB_ATT_GR: statement for selecting a maximum of 16 ATND groups.
    Mode: DA_M_CGS_MENGE_ATT_GR_PST
  • POP1: connection and class of service codes
    Mode: DA_M_CG_MARK1_PST
  • POP2: limiting values
    Mode: DA_M_CGS_TA_MARK2_PST
  • NODE_TBL: node number table (the node numbers are expanded to 4 places)
    Mode: DA_M_CGS_NODE_NO_ARY
  • COPIN: Class of Pin
    Mode: POWERSET( DB_M_COPIN_RNG )
  • CARRIER
    Mode: POWERSET( DB_M_CP_CARRIER_RNG )
