You can enable Switchover on bad SQL on the Functional Configuration screen; follow these steps:
1. At the System Configuration menu, type 2 , "Functional Configuration," and press <Enter>.
2. At the Functional Configuration screen, type 7 , Switchover on bad SQL, then press <Space> to
cycle through these options: Auto (typical for normal operation) or Off. To move to the next
column, for a remote modem, press <Tab>.
3. To return to the System Configuration menu, press <Esc>.
Monitor Data Transmission
The 2345 provides three screens for monitoring data transmission when running in framed mode.
• Two screens show statistics that are in the DSX3 MIB in RFC 2496; one shows the current 15
minute interval, the other shows a 24 hour interval. For details on the definitions, see RFC 2496.
• dsx3PESs: P-bit Errored Seconds (PES)
One second with a PCV, an Out of Frame (OOF) defect, or an AIS; does not increment
during unavailable seconds (UAS).
• dsx3PSESs: P-bit Severely Errored Seconds (PSES)
One second with 44 or more PCVs, an OOF, or an AIS; does not increment during a UAS.
• dsx3SEFSs: Severely Errored Framing Seconds (SEFS)
One second with an OOF or an AIS; does not increment during a UAS.
• dsx3UASs: Unavailable Seconds
The number of seconds that the interface is not available, which is from the start of 10
continuous PSESs or the start of a failure condition, whichever occurs first. The UAS ends at
the start of 10 contiguous seconds with no PSES if there is no failure or, if there is a failure
with clearing time of up to 10 seconds. If the failure took more than 10 seconds to clear, the
UAS ends at the start of 10 contiguous seconds with no PSES or when the clearing time
started. No other counter increments during a UAS.
• dsx3LCVs: Line Coding Violation (LCV) Error Event
Count of both BiPolar Violations (BPVs) and Excessive Zeros (EXZ) occurrences. One EXZ
increments the LCV by one, regardless of the number of zeros in the string.
• dsx3PCVs: P-bit Coding Violation (PCV) Error Event
Count of P-bit Parity Errors.
• dsx3LESs: Line Errored Seconds (LES)
The number of seconds with a Coding Violation (CV) or LOS defect.
• dsx3CCVs: C-bit Coding Violation (CCV) Error Event
Count of C-bit coding violations, CP-bit parity errors (C-bit Parity).
• dsx3CESs: C-bit Errored Seconds (CES)
One second with a CCV, an OOF, or an AIS; does not increment during a UAS.
• dsx3CSESs: C-bit Severely Errored Seconds (CSES)
One second with 44 or more CCVs, an OOF, or an AIS; does not increment during a UAS.
