Description:

This object specifies the physical format of an E1 logical span. The user will be allowed to configure an E1 span, if the IMG 1010 is configured for E1 via the host flags.

Accessing this Pane:

Field Descriptions:

Loop Timing Type:

Specifies whether that specific span is used for primary loop timing, secondary loop timing or not.

 

Coding Method:

Specifies the line coding of that specific span:

 

Enable CRC4:

Specifies whether CRC4 error checking is enabled or disabled:

 

Enable FEBE:

Specifies whether FEBE is enabled or disabled:

 

Line Length:

Specifies whether the E1 interface is 75 ohm or 120 ohm.

 

Signaling Method:

 

Layer 1 Management:

 

Transmit All Zeros:

Specifies whether transmit all zeros is enabled or disabled.

 

Loopback Mode:

Bearer or Signaling DS1’s can be configured for local or remote loopback. Each span offset must be individually configured.

 

Note: When you place a span in loopback mode the Span Status will indicate Out Of Service. Following the test you must manually put the span back in service by selecting the In Service button.

See Loopback Testing for more information.

 

Monitoring Fields:

Span Status:

This monitoring field indicates the current status of the E1 span.

 

Buttons:

In Service:

This button brings the E1 span in service.

Note: You must manually bring a span back in service following a loopback test.

 

Out Of Service:

This spans takes the E1 span out of service.

 

Default E1 Format:

The table below shows the default format for E1 spans. You must enable Clear Channel signaling to use timeslot 16 as a voice channel for out-of-band signaling (for example, an ISDN application).

Note: Clear Channel signaling must be enabled to use timeslot 16 as a D channel in ISDN applications.

 

Note: For CAS, channel 16 will appear as Out of Service.
