Display POTS Statistics
This report displays POTS statistics.JB Delay Mark
discarded, TX error No. of discarded transmitted packets due to:
- Heartbeat Lost - No. of transmitting Heartbeat
(signal-quality error) packets lost/errors
- Deferred - Count of frames for which the first
transmission attempts on a particular interface is
delayed because the medium is busy. The count
represented by an instance of this object does not
include frames involved in collisions
- Late Collision - Discarded transmitted frames
because a collision occurred. No. of times that a
collision is detected on a particular interface later than
512 bit-times into the transmission of a packet
- Excessive Collision - Count of frames for which
transmission on a particular interface fails due to
excessive collision
- Carrier Sense Lost - No. of times the carrier sense
condition was lost or never asserted when attempting
to transmit a frame on a particular interface. The count
represented by an instance of this object is
incremented at most once per transmission attempt,
even if the carrier sense condition fluctuates during a
transmission attempt
- Underrun - DMA underrun. Discarded outgoing
packets because there are no packets waiting in the
buffer
transmitter resets No. of times the Ethernet transmitter was reset after a
transmission error.
Parameter Description
Line X Active/Inactive Current status of line X
Active: Phone line connection is up
Inactive: Phone line connection is down
Buffers Rcvd No. of packets received from this POTS line
Buffers Sent No. of packets sent to this POTS line
Discarded Discarded packets due to Jitter Buffer Overrun. The
internal Jitter Buffer is full and could not allocate a
new free packet buffer
Underrun No. of times the POTS port was ready for a packet and
no packet was waiting in the Jitter Buffer
Overflow No. of packets put into the Jitter Buffer when the Jitter
Buffer was over the Over JB Mark level. The packets
are arriving too fast
