Instruction manual

Features and Services
Remote Access: Remote Access calls are fully covered in the SMDR call records. Failed remote
calls are shown in account field (see Figure 48).
Tandem Trunking: If an outgoing call is originated by a tandem tie trunk, the tandem trunk’s FAC
is recorded in the STN field. If no FAC exists for this trunk, then the 4-digit trunk number (9xxx) will
appear. No other SMDR fields are affected.
Administration Requirements
System:
● Send SMDR records to SMDR Port (yes or no; default = yes).
● Minimum length (seconds) of successfully dialed calls that are reported by SMDR (10-255;
default = 40).
● Type of SMDR peripheral: CAT or non-CAT (yes = CAT, no = non-CAT).
Hardware Requirements
An AT&T Model 572 printer or any standard RS-232 serial 80-column ASCII printer is required for
printing the SMDR output. The printer must be dedicated to SMDR to ensure that all calls are
recorded. An AT&T Call Accounting System may also be used as the SMDR output device (see
below).
The printer can be directly connected to Port 2 of the ZTN130 CPU/MEM (Call Processing
Unit/Memory) circuit pack or switched access (either on- or off-premises) can be provided.
Connection is the same as described for the SAT.
SMDR port parameters areas follows:
● No parity; bit is set to zero (mark or space),
● 1 start bit, 1 stop bit, and 7 data bits.
● Baud rate defaults to 1200 (can be set to 300).
● DTR (data terminal ready) required from printer.
● RTS (ready to send) and CTS (clear to send) not required.
● No flow control.
Detailed connection information is provided in Figures 2-51 through 2-55.
Maximum cabling distances are provided in Section 5, “Technical Specifications.”
