15. FORCED ACCOUNT CODE [F-7] can be recorded on SMDR, for INWATS and CO incoming calls,
when used in conjunction with the REMOTE ACCESS TO SYSTEM [R-2] service feature.
16. FORCED ACCOUNT CODE [F-7] cannot be registered on SMDR if the incoming REMOTE ACCESS
TO SYSTEM [R-2] calls are terminated to stations via night service or DID.

19. A maximum of 28,000 simultaneous calls can be stored in the system memory (active calls). When a call
is completed, the record is sent to the output device and is removed from memory.
20. If an overflow of active calls occurs, calls are allowed to complete and are not recorded.
21. CALL TRANSFER - ALL CALLS [C-11]: The first or last station (system option) on the call is the
number recorded in the called number field. Also available as a system option is the provision of a separate
call record for each station.
22. CALL FORWARDING - INTERCEPT/ANNOUNCEMENT - ATTENDANT [C-75]: The called
telephone number is recorded for Attendant-assisted incoming calls.

Station Message Detail Recording - PRI S-83
Service Conditions (cont’d)
29. DIRECT INWARD DIALING (DID) [D-8] trunk calls: If the call is to the Attendant, the Attendant can
input an account code before extending the call.
30. INDIVIDUAL TRUNK ACCESS [I-4]: The Attendant cannot dial in an SMDR account code before using
direct trunk selection.
31. Incoming tie trunk calls: If an incoming call to the Attendant is extended, the Attendant can input an
account code.
32. CALL FORWARDING - INTERCEPT/ANNOUNCEMENT [C-25]: When an incoming trunk call
receives intercept treatment routing it to the Attendant, SMDR functions as if the Attendant was dialed
directly.
33. Night service: When the system is in the night service mode, SMDR records calls routed to the Night
station (answering station).
34. CALL-BY-CALL SERVICE SELECTION - PRI [C-105]: Only Trunk Provisioning service is available.
35. OUTGOING TRUNK QUEUING [O-2]: The SMDR records the dialed account code. When the caller is
called back with a trunk, the account code does not need to be reentered.
36. REMOTE ACCESS TO SYSTEM [R-2]: If the call is terminated in the PBX or tandeming through the
PBX, the remote access trunk and route numbers are recorded. A FORCED ACCOUNT CODE [F-7] can
be requested upon entry to the network via remote access. If a FORCED ACCOUNT CODE [F-7] is used,
it can be recorded by SMDR.
37. SERIAL CALL [S-15]: The duration of the total call is recorded on the last station call.
38. STATION HUNTING - CIRCULAR [S-7], STATION HUNTING - SECRETARIAL [S-8], STATION
HUNTING - TERMINAL [S-9]: The hunted-to station is recorded in the called number field.
39. TANDEM SWITCHING OF TIE TRUNKS 2/4 WIRE [T-1] calls: The calling number is the incoming
trunk route plus trunk number; the called number is the number dialed.
40. CALL WAITING - TERMINATING [C-12], CALL WAITING - ORIGINATING [C-31]: The called
number is recorded and SMDR recording of call duration begins when the station answers.
41. UNIFORM CALL DISTRIBUTION (UCD) [U-1]: The calling number is the incoming trunk route plus
the trunk number. If the call is to a PBX station, the station answering the number is recorded as the dialed
number.
42. On an incoming trunk call to the Attendant, the Attendant call record starts upon answer and completes
when the Attendant releases. A station call record starts when the Attendant releases and completes when
the station goes on-hook. If required, a station record will not be generated if the station does not answer.
43. A system option is available to allow or restrict call completion in the case where a failure occurs in
transmitting SMDR data from the Local Processor to the I/O port.
44. Additional hardware is required to implement this feature.

numbers maximum.
6. TOLL DENIAL/TOLL DIVERSION [T-6] and TOLL RESTRICTION - 3/6-DIGIT [T-7] may or may not
be applied to Speed Calling, as desired.
7. LEAST COST ROUTING - 3/6-DIGIT [L-5] can be provided via Speed Calling access.
8. Each individual station equipped with this feature programs their own personal Speed Calling numbers.
9. If SPEED CALLING - STATION - PRI is assigned to a Module Group, SPEED CALLING - GROUP -
PRI [S-85] shares the same memory tables; so careful consideration should be taken when programming.
10. SPEED CALLING-STATION data is retained in memory, even if the system is reinitialized or in the event
of a power failure, by means of a hard disk for a system.
11. SPEED CALLING - STATION - PRI data remains even if system is reinitialized.
12. Stations can be added or removed from a group only via the MAINTENANCE ADMINISTRATION
TERMINAL (MAT) [M-18].
13. A user cannot dial the called party sub-address as abbreviated codes.

2. A station is assigned blocks as primary stations, and associate stations to that group as secondary stations.
The primary station can program 10 memory blocks commonly used as Speed Calling numbers for that
group; therefore, a group can consist of 100 Speed Calling numbers maximum.
3. Each abbreviated call code can store a maximum of 24 digits, including access codes.
4. A station can be assigned as a primary station for only one group of memory blocks.
5. There is no limit to the number of secondary stations assigned to one Primary group.
6. Secondary and primary stations must belong to the same Module Group.
7. A secondary station can only be assigned to one Primary group.
8. TOLL DENIAL/TOLL DIVERSION and TOLL RESTRICTION - 3/6-DIGIT [T-40] may or may not be
applied to Speed Calling, as desired.

SMDR for Data Call - RS232C - PRI S-88
S-88  SMDR for Data Call - RS232C - PRI
General 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 computer as each call record is compiled.
7. If an outgoing call is directed to a trunk that cannot accept answer supervision from the Central Office, the
call start time will be a 30-second default (timing 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. Detailed management
reports are made readily available to the user.
