-- 5210TL-130200-1001 CALL TRACING6.0 Call tracing provides troubleshooting information for experienced technical personnel trained in the operation and maintenance of the system. Call tracing involves analyzing the address data contents of channel memory, control memories A and 6, and pad memory as the system makes voice/data connections. Connections take place during a period of time, and employ certain parts of the system. The time interval is called a time slot, and the parts which come into play depends on the type of connection (see Figure 6.1). The channel memory and control memory A are used in two-party calls while channel memory and control memories A and B are used in three-party calls. All of these memories are interrelated with a time slot/channel number. A complete memory cross-reference is shown in Table 6.1. A brief description of how a call is processed will help the user understand call tracing. 1. A call has been established between Directory Number 2083 (physical location: group A, universal card slot 5, circuit 6) and directory number 2055 (physical location. group B, universal card slot 6, circuit 3) (see Figure 6.2). 2.The system stores the hardware ID of the off-hook directory number in a time slot (channel number) in channel memory. Here, 2083 (HID 56 hex) is assigned channel 18 (address 0449) in channel memory.
