SMDR for Data Call - RS232C - PRI S-88
S-88 SMDR for Data Call - RS232C - PRIGeneral Description
This feature provides a call record of all outgoing station-to-trunk and incoming PRI trunk-to-station data calls.
When this feature is provided, an RS232C output port is used, permitting direct interface with a customer-owned
computer system. All output is in ASCII format, and includes the following:
• Calling telephone number
• Called telephone number (24 digits maximum)
•Route Number
• Start of Call Time
• Disconnect Time
• Year, Month and Date
• Attendant Handled
Operating Procedure
No manual operation is required. Call records are output automatically.
Service Conditions
1. STATION MESSAGE DETAIL RECORDING (SMDR) information facilitates analysis of trunk and data
port traffic, and can be used for cost allocation or billing purposes.
2. SMDR can be programmed to record all outgoing calls or only toll calls, depending upon user
requirements.
3. Incomplete and abandoned calls are discarded by SMDR, depending upon system and other data
assignment.
4. If DATA CALL ROUTE ADVANCE [D-52] or DATA CALL LEAST COST ROUTING - 3/6-DIGIT
[D-49] is provided with the system, SMDR records the route numbers selected for outgoing calls.
5. The maximum number of dialed digits cannot exceed 24.
6. When customer-owned computer equipment is connected via the RS232C interface, SMDR information
is transmitted directly to the comput er as each call record is compiled .
7. If an outgoing call is directed to a trunk that cannot accept answer supervision from the Central Offi ce, the
call start time will be a 30-second default (tim ing variable in system data) after the last digit is dialed. (This
timing is variable in system data.)
8. If the distance between the RS232C I/O port and the processing computer exceeds 50 feet (15 meters), an
asynchronous-type modem should be used.
9. RS232C Interface specifications:
Synchronization: Asynchronous
Data Speed: 9600 bps max.
Code: ASCII 7-bit + parity bit
Maximum Distance: 50 ft. (15m) without modem
10. The NEAX/ASTRA COMPUTER COMMUNICATION SYSTEM (CCS) [N-11] feature provides for
collection, storage, analysis and processing of SMDR information on the premises. Detaile d managemen t
reports are made readily available to the user.
