For outgoing calls, up to 15 digits may be recorded, excluding the ARS or facility access code but including the O or 1 prefix (to identify local and toll calls) and 950- 1 0XX and 10 XXX interconnect access codes.

Numbers longer than 15 digits will be truncated.

.Data Records: The system prints call records for incoming and outgoing (external) data calls. Calls are considered data calls if they involve a data extension.

The following list describes the SMDR data collected for each call and the number of characters in each field. All information is right justified in its field, unless otherwise indicated. The record is provided in a standard 80-column format. The headings for each record item are noted in bold type. These headings are printed across the top of each page. Page advance is determined by counting lines based on a fixed page length. Each record is followed by a carriage return and a line feed.

The system can provide for the storage of up to 100 SMDR records. If more than 100 records are received while the printer is disconnected, a message “Calls Lost Due To Call Record Overflow” is provided when a printer is re-attached.
