ADTRAN 604, 612, 616, 606, 624 system manual Displays the T1 performance data

Section 4 User Interface Guide Total Access 600 Series System Manual

INTERFACES (T1) > CONFIG > LINE CODE

This sets the line code for the T1 interface. The setting must match the line code of the circuit to which the interface is connected. Choices are B8ZS (bipolar with 8-zero substitution) and AMI (alternate mark inversion). Default is B8ZS.

INTERFACES (T1) > CONFIG > EQUALIZATION

Select the line build out for the T1 interface. These are attenuation settings. 0 dB is the strongest signal, and the other settings make the T1 transmit signal weaker. The setting of this field depends on whether the circuit is provisioned for DS1 by the telephone company. The choices are 0 dB, -7.5dB, -15 dB, -22 dB. Default is 0 dB.

INTERFACES (T1) > CONFIG > CSU LPBK

Configures the Total Access 6XX to respond (ENABLE) or not respond (DISABLE) to a received ANSI Inband CSU loopback pattern. DISABLE ALL configures the Total Access 6XX to disregard ALL loopback commands sent inband or over the FDL. Default is ENABLE.

INTERFACES (T1) > CONFIG > RX SENSITIVITY

Configures the sensitivity of the T1 receiver for this interface to provide increased sensitivity for long-run T1 applications. Choices are AUTO (default), -36 dB, and -10 dB.

INTERFACES (T1) > STATUS

Displays the T1 status including performance data and alarm histories.

INTERFACES (T1) > STATUS > PERFORMANCE

Displays the T1 performance data.

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS

Provides current (15-minute window) status on key performance measures as specified in ANSI T1.403 and AT&T TR 54016 for each of the T1 ports as well as historical statistical totals.

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS > INTERVAL

Identifies the interval (CURRENT or TOTAL) for the listed performance statistics.

INTERFACES (T1) > STATUS > PERFORMANCE > CURRENT AND TOTALS > ES

ES (Errored Second) - For ESF mode, an errored second is defined as a second with one or more Path Code Violations (PCVs), or one or more Out of Frame (OOF) defects, or one or more Controlled Slip events, or a detected AIS (blue alarm) defect. For D4 (SF) mode, the presence of Bipolar Violations (BPVs) also triggers an errored second.
