Modulation Standard

Modulation standard can be V.21, Bell103, V.22, V.22 bis, Bell 212, V.23, V.32, V.32 bis, V.32terbo, V.34, V.34+, or K56Flex 1.1.

TX/RX Bit Rate

TX is the bit rate from the local DCE to the remote DCE. RX is the bit rate from the remote DCE to the local DCE. These rates may be asynchronous.

Connect Protocol

Connect protocol for the current session, which can be SYNC mode, ARA1.0, ARA2.0, LAP-M, MNP, FAX mode, SS7/COT, or V.110.

Compression

Compression protocol used for the current connection, which can be None, V.42 bis TX, V.42 bis RX, V.42 bis both, or MNP5 data compression.

Link Signal Quality

Measure of line quality for a given bit rate where 0 is the worst and 3 is steady state. If a 1 or 2 is present, the modem must shift down to a lower rate. Likewise, if the value is 4 to 7, the modem speeds shift up to a higher rate. If the value is high (for example, 7) and the bit rate is low, then there may be a problem at the remote end receiver.

SNR

The ratio measurement (in dB) of the desired signal to noise. This value can range from 0 to 70 dB and changes in 1 dB steps. Note that a 28.8-kbps connection demands an SNR of about 37 dB. Any values lower than this level result in a diminished quality of connection. A 33.6-kbps connection demands a signal-to-noise ratio (SNR) of 38 to 39 dB. Also note that a “clean” line has an SNR of about 41 dB.

TX/RX Symbol Rate

TX is symbol rate used to send samples to the line. RX is the symbol rate used to receive samples off of the line. The rates are synchronous with each other.

TX/RX Carrier Frequency

For TX, carrier frequency used by the local DCE. For RX, carrier frequency used by the remote DCE.

TX/RX Trellis Coding

Adds dependency between symbols in order to make the detection in noise more robust (Forward Error Correction). Modems may use 8 (V.32, V.32 bis, V.17), 16, 32, 64 (V.34, V.34+, V.90, K56flex), or no trellis coding (V.22, V.22 bis, V.21, Bell212, Bell103, V.29, V.27).

TX/RX Preemphasis Index

Involves shaping the raw transmit spectrum in order to deal with spectrum roll-offs. The preemphasis index can take on the values 0 to 10. A zero denotes no reshaping. Typical values usually fall in the ranges from 0 to 2 or 6 to 7. This technique is used with V.34 and V.34+ standards.

TX/RX Constellation Shaping

A method for improving noise immunity by using a probability distribution for sent signal points. The signal states used to predict the sensitivity to certain transmission impairments. Values may be either Off-none or On-active. This technique is used with V.34 and V.34+ standards.

TX/RX Nonlinear Encoding

Occurs during the training phase and moves the outer points of the constellation away in order to deal with nonlinear distortion. Nonlinear distortion (0 to 200 Hz) tends to affect the higher power signals. Moving the outer constellation points out reduces the chance of error. Values may be either Off-none or On-active. MICA modems support nonlinear coding in both directions. This technique is used with V.34 and V.34+ standards.

TX/RX Precoding

Serves the same purpose as the preemphasis index but instead manages the bits and not the raw transmit signals. This is done only when requested and therefore will occur in the RX mode. The values may be either Off-none or On-active. This technique is used with V.34 and V.34+ standards.

TX/RX Xmit Level Reduction

Affects the transmit signal with 0 to 15 in dBm of reduction. If nonlinear distortion is detected, the modem prompts the client for a lower-powered TX signal. If the remote end detects nonlinear distortion, it may request that the sender lower the TX signal. This technique is used with V.34 and V.34+ standards.

Receive Level

The power of the received signal in dBm steps. It ranges from 0 to –128 dBm. Typically the range in the United States is about –22 dBm, and in Europe is –12 dBm. A good range is from –12 dBm to –24 dBm.

Frequency Offset

The difference (in hertz) between the expected RX carrier frequency and the actual RX carrier frequency.

Phase Jitter Frequency

Peak to peak differential (in hertz) between two signal points. Uncanceled phase jitter looks like “rocking” of the baseband quadrature amplitude modulation (QAM) constellation. The points look like arcs with the outer points having longer arcs.

Phase Jitter Level

Amount of phase jitter measured and indicates how large the “rocking” is in degrees. On an oscilloscope, the constellation points would look like crescent moons. Values can range up to 15 degrees. The typical value is zero (that is, phase jitter is not normally present).

Far End Echo Level

Over long connections, an echo is produced by impedance mismatches at 2-wire-to-4-wire and 4-wire-to-2-wire hybrid circuitry. The far-end echo level (that portion of the sent analog signal that has bounced off of the remote modem analog front end) may range from 0 to –90 in dBm.

Phase Roll

Phase roll affects the echo signal coming back. A certain constellation pattern is sent from a modem and arrives at to the central office. Some echoed form of this signal/constellation pattern is sent back. However, the constellation shape may be rotated from 0 to 359 degrees. This rotation is called the phase roll.

Round Trip Delay

Total round trip propagation delay of the link (in milliseconds). This is important for proper echo cancellation. The amount that the delay varies on the network.

Total Retrains

Count of total retrains and speed shifts.

Self Test Error count

Total errors generated during a self-test run.

EC Retransmission count

The number of times the NextPort has gone into error recovery in the TX direction for a particular connection. The larger the number, the worse the connection. However, this parameter should be weighed against the count produced by EC packets sent and received in order to determine if there should really be a concern.

EC packets transmitted/received OK

Error correction (EC) packets sent is the number of TX frames that the client modem accepted. EC packets received is the number of data RX frames accepted.

EC packets (Received BAD/ABORTED)

This is identical to the EC Retransmission count field.

PPP/SLIP packets transmitted/received

Total count of PPP/Serial Line Internet Protocol (SLIP) packets sent and received. This total could include all PPP/SLIP packets, including BAD/ABORTED packets.

PPP/SLIP packets received (BAD/ABORTED)

Total count of the bad or aborted PPP/SLIP packets, which is a subset of PPP/SLIP packets received. A counted PPP packet has a bad frame check sequence (FCS), or the SLIP packet has a transparency error.

RBS Pattern

Reports the number of robbed bits detected in the connection. The robbed bits are used for inband signaling. This information is reported only for K56Flex (by the analog modem) and is found only on a channelized line such as T1 or E1. The six least significant bits (LSBs) of the returned value indicate the periodic robbed bit signaling (RBS) pattern where a 1 denotes a pulse code modulation (PCM) sample with a robbed bit.
