Install Station Message Detail

Recording (SMDR)/Call Detail

Recording Unit (CDRU) Interface

The interface between the switch and Station Message Detail Recording (SMDR) can be through a Processor Data Module (PDM), Trunk Data Module (TDM), or 212-type modem.

For connections between the switch and the Processor Data Module (PDM) or Trunk Data Module (TDM), refer to the section on installing Processor Data Modules (PDMs).

The connection between the switch and the 212-type modem is the same as for external ringing (Figure 9-11).When a 212-type modem is used, an external pooled modem circuit pack must be provided. One of the pooled modem’s conversion resources is dedicated to the Station Message Detail Recording (SMDR) output device.

Connections between the G3i switch and an Asynchronous Data Unit (ADU) or data module are the same as for remote administration devices such as the Generic 3 Management Terminal (G3MT). These connections are shown in Figure 9-32and Figure 9-33.All such connections require the mode 2 to mode 3 conversion resource shown in these figures.

Administer your connections as described in DEFINITY Communications System Generic 3 V2 Implementation, 555-230-655.

A TN726B data line circuit pack may also be used. If so, Processor Data Modules (PDMs), Trunk Data Modules (TDMs), or 212-type modems are not required for the data terminal equipment (DTE). Connections between the switch and the Station Message Detail Recording (SMDR) output receiving device is the same as a customer-provided data terminal (Figure 9-33).

The Station Message Detail Recording (SMDR) output device can be connected directly to the data communications equipment (DCE) connector on the rear of the control carrier. This connection is made using a RS-232 cable. A Processor Data Module (PDM) or Trunk Data Module (TDM), modem, or Asynchronous Data Unit (ADU) is required.
