Page 66: Table 2-11: Payload Sequence Capture Timing
Functional Overview Overhead and Payload You can set up the VX4610 to capture overhead and payload data into memory. Capture An overhead/payload capture is qualified by a trigger event or signal that you specify. When a capture occurs, one Transport/Section Overhead and a continu- ous sequence of payloads are acquired into memory.
Page 67: Table 2-12: Internally Derived Trigger Events
Invalid NDF None Pulse This trigger event has an uncertainty of one frame when used to capture overhead or payload. The VX4610 does not use the status of S-bits to detect the LOP trigger event. 2–16 VX4610 SDH/SONET Generator/Receiver User Manual...
Page 68 Trigger Input. Trigger input is used in the payload and overhead capture process. The capture process has two steps. First, the capture is armed when an INITiate command is sent. Second, the capture is completed when the VX4610 receives a trigger input. The trigger input can originate from one of several sources:...

Tributary Signal Testing Add/Drop/Test Option Only This section discusses five ways to use the Add/Drop/Test Option of your VX4610 to test the viability of a network element (NE) and portions of the network. VX4610 as a Stand-Alone You can use the VX4610 as a stand-alone tributary test set without using any Tributary Test Set SONET or SDH features.
Page 96: Figure 2-13: Setup For Testing The Sdh Tributary Payload Mapping
Mapping The VX4610 maps a pattern into the tributary payload of a SONET/SDH signal. This signal is then generated by the VX4610 and transmitted to an NE. The VX4610 receives the SONET/SDH signal and measures both the SONET/SDH and mapped tributary signals.

Status and Events...
Page 532: Status And Event Reporting System
Status and Events The Status and Event Reporting System reports asynchronous events and errors that occur in the VX4610 SDH/SONET Generator/Receiver. This system consists of four 8-bit registers and two queues that you access through the command language. You can use these registers and queues to query the instrument status and control the interrupts that report events.
Page 533 Request Service (obtained from a serial poll) shows that the VX4610 has requested service from the GPIB controller. Master Status Summary (obtained from *STB? query) summarizes the event status bit and message available bits in the Status Byte Register.
Page 534 The Standard Event Status Register, shown in Table 4–3, records many types of Register events that can occur in the VX4610. Use the *ESR? query to read the contents of this register. The response is the sum of the decimal values for all bits set.
Page 535 VX4610 was executing a command or query. Table 4–6 on page 4–9 lists the execution error messages. Command Error shows that an error occurred while the VX4610 was parsing a command or query. Table 4–5 on page 4–8 lists the command error messages. –...
Page 536 Query Error (bit 2 in the Standard Event Status Register) to indicate the lost response. The System Error and The VX4610 error and event messages are stored in the System Error and Event Event Queue Queue. Use the SYSTem:ERROr? query to get the event number and a text description of the event.
Page 537: Status And Event Reporting Process
Event Queue (1). If the corresponding bit in the Event Status Enable Register is also enabled (2), then the event status bit in the Status Byte Register is set to one (3). 4–6 VX4610 SDH/SONET Generator/Receiver User Manual...
Page 538: Synchronization Methods
Synchronization Methods Although most GPIB commands are completed almost immediately after being received by the VX4610, some commands initiate processes requiring additional time. For example, after you send a SENSe:DATA:TELecom:AUTOscan command, you must wait until it has completed execution before you give another command or query.
Page 539: Messages
Status and Events Messages The VX4610 generates error messages in response to events caused by com- mands or queries. Each type of event sets a specific bit in the Standard Event Status Register. Thus, each message is associated with a specific Standard Event Status Register bit.
