Testing RAM Accesses: dalNbcsTswDiagTestRam
Verifies the hardware access to the device internal RAM by writing and reading back values. The
following types of RAM tests can be performed: single write/read, walking ones, migrating ones,
and aliasing. Note that both connection maps are tested for all types of tests listed above. The
first three types can be performed on either a user-specified range or the entire RAM. Aliasing is
always performed on the entire RAM.
Controlling diagnostic loopbacks: dalNbcsTswDiagLpbk
This function is used to control the diagnostic loopbacks available on a time switch device
PRBS Generation/Monitoring Control
This section describes the functions that are used to configure the pseudo random pattern
generation and monitoring on the working and protect links. The granularity is assumed to be
STS-1.
Configuring payload for the PRGM: dalNbcsTswCfgPrgmPyld
This function configures the payload for the PRBS generator or monitor on the working and
protect links. The payload can be configured as 12 STS-1’s, 4 STS-3c’s , a combination of STS-
1’s and STS-3c’s or a single STS-12c.
