# SONET Interface Configuration

To display SONET interface configuration, select SONET Interface Configuration from the CATEGORY pulldown menu. The following information is displayed:

SONET or SDH Signal (sonetMediumType)

Elapsed Time (sonetMediumTimeElapsed )

Valid Intervals (sonetMediumValidIntervals )

Line Coding (sonetMediumLineCoding)

Line Type (sonetMediumLineType)

Circuit Identifier (sonetMediumCircuitIdentifier)

# SONET or SDH Signal (sonetMediumType)

Identifies whether a SONET or SDH signal is used across this interface. The value can be 1 or 2, as follows:

|  | SONET
|  | SDH

# Elapsed Time (sonetMediumTimeElapsed)

The number of seconds that have elapsed since the beginning of the current error-measurement period (maximum 900 seconds, partial seconds included).

# Valid Intervals (sonetMediumValidIntervals)

The number of previous 15-minute intervals for which valid data has been stored. SONET devices must support at least this specified number of intervals.

Minimum 4 (= 1 hour)

Default 32 (= 8 hours)

Maximum 96 (= 24 hours)

The number of complete 15 minute intervals that the device has actually been online is used if it is less than the number specified here.

# Line Coding (sonetMediumLineCoding)

The line coding for this interface. Values depend on whether it is an electrical or optical interface.

Electrical interface:

| 2 | B3ZS (sonetMediumB3ZS)
|  | CMI (sonetMediumCMI)

Optical interface:

|  | Non-Return to Zero (sonetMediumNRZ)
|  | Return to Zero (sonetMediumRZ

The value 1 is for anything else (sonetMediumOther).

# Line Type (sonetMediumLineType)

Specifies the type of line to which this interface is connected. Lines may be optical fiber or electrical:

Optical fiber:

| 2 | short range single mode (sonetShortSingleMode)
| 3 | long range single mode (sonetLongSingleMode)
| 4 | Multi-mode (sonetMultiMode)

Electrical:

| 5 | Coaxial (sonetCoax)
|  | UTP (sonetUTP)

The value 1 is for anything else (sonetOther).

# Circuit Identifier (sonetMediumCircuitIdentifier)

The identifier for the circuit, provided by the TELCO transmission vendor. Use this to help with troubleshooting.
