Matrix PRASAR UCS - Station Message Detail Recording-Posting

Matrix PRASAR UCS System Manual 1103
Station Message Detail Recording-Posting
The Station Message Detail Record (SMDR)-Posting feature of PRASAR UCS is used for interfacing the system
with a third party Call Accounting Software (CAS).
When PRASAR UCS is interfaced with a third party Call Accounting Software (CAS) to determine the cost of the
calls made by the extension users, the system uses SMDR-Posting to send to CAS call record details, like number
to which the call was made by the extension user, number of the extension from which the call was made, the date
and time when the call was made, the duration of the call, metering pulses incurred for the call, etc. On receipt of
this information, the CAS calculates the cost of the call for billing.
As different CAS interfaces support different protocols, the PRASAR UCS offers the flexibility to send call detail
records using the protocol supported by CAS. PRASAR UCS supports as many as 16 different widely-used CAS
protocols such as, Holidex, Hobic, Micros A, Micros B, Comm One, Call-Inn, Bell-HOBIC, XIOX, RSI and others.
Each posting protocol has its own handshaking protocol and call record format. You may configure any one of
these depending upon the protocol supported by CAS you have interfaced with PRASAR UCS. It is also possible to
customize the posting protocol to match the settings required by the CAS you have interfaced.
PRASAR UCS supports SMDR-Posting on USB to Communication Port as well as on TCP/IP Ethernet (LAN/WAN)
Port. Thus, the CAS can be interfaced either on the USB1 to COM port, USB2 to COM port or the Ethernet port
(LAN/WAN) of the PRASAR UCS.
SMDR-Posting sends outgoing call records only.
SMDR-Posting Protocols
The PRASAR UCS supports different SMDR posting protocols from the system to CAS. The flow of messages
between the PRASAR UCS and the protocols of CAS Interface (Matrix and Blind Send) are described below:
Matrix
• Positive Response from the CAS
• Negative Response from the CAS
PRASAR UCS to CAS CAS to PRASAR UCS
<STX> -Call Record-<ETX> <BCC>
ACK
PRASAR UCS to CAS CAS to PRASAR UCS
<STX> -Call Record-<ETX> <BCC> and wait for
Response to Data Timeout (sec), default 3 sec.
NAK
Retransmit <STX> -Call Record-<ETX> <BCC>
and wait for Data Transfer Retry Timer (sec) - on
Negative Response, default 3 seconds.
