ATM Board Framer Looparound Test (#1260)
Destructive
This test verifies the board’s circuit (Time Division Multiplexing) and packet paths
using an on-board, dummy virtual circuit. Before running the test, you must
■ busyout the ATM-TRK circuit pack (
busyout board UUCSS
) and
■ switch synchronization (
change synchronization
) from the ATM-TRK
circuit pack
If the ATM-TRK circuit pack is supplying synchronization, the test aborts.
The test sends a digital counter from one of the tone generators via one of the
TDM bus time slots. The ATM framer interface converts this digital counter to ATM
cells and loops them back internally. The ATM-TRK circuit pack converts the cells
