NEC 2000 IPS manual Data Transmission Sequence for Ethernet Interface, System Capacity

Chapter 10 System Input/Output (I/O) Interfaces

b. SMDR with AP00

oAP00 without expansion memory (standard): up to 1600 calls (if central office feature is used, up to 800 calls)

oAP00 with expansion memory (optional): up to 27000 calls (if central office feature is used, up to

26000 calls)

oWhen a call is completed, the record is sent to the output device and is removed from memory. o If the amount of calls exceed the SMDR memory, those overflow calls will not be recorded.

The built-in SMDR cannot be provided when AP00B with MRC-C program is mounted.

Account Codes, Forced Account Codes, Authorization Codes and DISA Codes on Tandem connections (SMDR with AP00 only) are reported in the applicable call record.

SMDR with AP00 provides a record of incoming Tie Line tandem calls where another trunk is dial accessed.

For details of SMDR format, data stream, memory buffer, etc., refer to the Installation Procedure Manual/Feature Programming Manual.

Up to 16 digits of the calling subscriber’s number for Automatic Number Identification (ANI) and CPN (ISDN) can be recorded in the SMDR by system programming.

Data Transmission Sequence for Ethernet Interface

Establishing a connection, outputting billing Information, and releasing a connection are performed between the PBX and the SMDR terminal in the following timings.

Timing to Establish a Connection

oA connection is established when a connection request is received from the SMDR terminal.

Timing to Output Billing Information

oBilling information is output when a polling request is received from the SMDR terminal connected to LAN.

Timing to Release the Connection

oThe connection is released when the SMDR terminal does not receive data from the PBX in a predetermined time interval. Also the connection is released when the PBX receives connection release text from the SMDR terminal or does not receive data from the SMDR terminal within a given time interval.
