Table 5-22. CSU_STAT? and REMOTE_STAT? Response Data (continued)
Data Description Typical Value
BPV SEC Bipolar violation seconds - A non-zero signal element in an
AMI (bipolar) signal that has the same polarity as the
previous non-zero signal element. Section 6.2 –
ACS-160
Series Monitor & Control Features gives more information on
bipolar violations.
Under normal operating
conditions, you should not
have any BPV seconds.
SLIP SEC Controlled slips seconds - The occurrence of a replication, or
deletion, of a DS1 frame at the receiving terminal. A
controlled slip may occur when there is a difference between
the timing of a synchronous receiving terminal and the
received signal. Under normal operating
conditions, you should never
have any SLIP errors.
PLB SEC Payload loopback seconds - A loopback which results in a
1.536 Mbps loopback of the payload of the signal received
by the customer installation from the network installation
maintaining bit-sequence integrity for the information bits. Under normal operating
conditions, you should not
have any payload loopback
seconds.
YEL SEC Yellow alarm seconds - Signal transmitted if a DS1 terminal
is unable to synchronize on the DS1 signal for some interval
of time indicating an LOF (loss of frame) condition.
Commonly referred to as yellow signal, also known as a
remote alarm indication (RAI). Under normal operating
conditions, you should not
have any yellow alarm
seconds.
Clear CSU_STAT? and REMOTE_STAT? Data
Each CSU_STAT? and REMOTE_STAT? register can hold from 0 to 65535 events. When a register
reaches 65535 events, it remains at that number until cleared to 0 with a CLEAR command. For
example, to clear an ACS-163 multiplexer’s CSU_STAT? and REMOTE_STAT? registers, issue a
command in this form:
<ADDRESS>:TERM:CLEAR:;
The CLEAR command clears both the CSU_STAT? and REMOTE_STAT? registers. You cannot clear
individual data registers.
Issue ATT_STAT? Command
You can query a summary of the ACS-160 Series multiplexer’s AT&T TR54016 performance
registers by issuing a ATT_STAT? command to its TERM, DI-A, or DI-B module. Table 5-23 shows
examples of ATT _STAT? commands for ACS-160 Series multiplexers.

Evaluate ATT_STAT? Responses
The 15-minute ATT_STAT? registers can hold a maximum of 900 events, one for each second in
the interval (60 seconds per minute X 15 minutes = 900 seconds). The 15-minute interval
registers should never exceed 900.
The 24-hour registers can hold a maximum of 65535 events. If the number of events exceeds
65535, the register remains at that number until the point in the current 24-hour period when
there is not a 15-minute event record. At that time, the sum of the 15-minute intervals decreases.
