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 

 (bipolar with 8-zero substitution) and 

 (alternate mark 

inversion). Default is 

.

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 

, 

, 

, 

. 

Default is 

.

Configures the Total Access 6XX to respond (

) or not respond (

) to a received ANSI 

Inband CSU loopback pattern. 

 configures the Total Access 6XX to disregard ALL loopback 

commands sent inband or over the FDL. Default is 

.

Configures the sensitivity of the T1 receiver for this interface to provide increased sensitivity for long-run 
T1 applications. Choices are 

(default), 

 

, and 

 

. 

Displays the T1 status including performance data and alarm histories.

Displays the T1 performance data.

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.

Identifies the interval (

 or 

) for the listed performance statistics.

 (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.
