Circuit Group

Description:

The circuit groups are created under the ISUP group. The starting and ending spans and channels are configured from drop down menus

Accessing this Pane:

Dialogic IMG EMS -> Routing Configuration -> Channel Groups -> Channel Group (of type SS7) -> ISUP Group -> Circuits

Field Descriptions:

IMG Name

The name of the IMG on which the group resides. This has a drop down menu displaying all IMG's configured under the IMG Logical Group.

 

IMG Interface

Signaling - Use the ports labeled Signaling/Timing on rear of IMG

Bearer - Use the ports labeled Bearer on rear of IMG

 

Start Interface Offset

This is the offset on the rear of the IMG. The Start Interface Offset is the Offset that the first span the CICs will get configured on.

 

End Interface Offset

This is the offset on the rear of the IMG. The End Interface Offset is the ending span that the CICs will get configured on.

 

Start Channel

Within the Offset there are 24 channels (T1) and 32 Channels (E1). User can select which channel in the offset to start configuring CICs on

 

End Channel

Within the Offset there are 24 channels (T1) and 32 Channels (E1). User can select which channel in the offset the last CIC is configuring on

 

Start CIC

Give this field a numerical value corresponding to the starting CIC number.

 

Skip Channel 16 (Default = False)

Note: When configuring SS7 on E1 channel 16 can be reserved for signaling, or not used. If out of band signaling is configured on channel 16 or the channel is not configured as a CIC, the CIC numbering no longer matches the time-slot numbering. The next two fields work toward alleviating the issue. The skip channel 16 field is supported in E1 protocol only.

 

False (Do Not Skip Channel 16)

The default value for this field is false. When false is selected channel 16 and each multiple of 16 will not be skipped when CICs are assigned to the time-slots. In this configuration a CIC will be assigned to channel 16. As displayed in the table below CIC #16 is assigned to time-slot 16.

Display Table

 

 

 

In Service:

Bring a CIC into service from an Out of Service State

 

Out of Service:

Take a CIC Out of Service

 

Maintenance Block:

Initiate a Maintenance Block on a specific CIC or range of CIC's. Calls will not be processed on a CIC put into Maintenance Block Mode. Any calls that are on that circuit will be brought to an idle state gracefully. Any calls on that cic will be allowed to continue until call is released.

 

Maintenance Unblock:

Unblock a CIC or range of CIC's from the Maintenance Block state

 

Reset:

Reset a CIC.

 

Continuity Check Request (COT Test):

To initiate a Continuity Check on a CIC or a group of CICs, right-click on the CIC(s) entry and select Continuity Check Request. The results will appear in the Manual COT Result column (Start, Start NACK, Success, Failure).

 

Note: COT cannot be performed on JT-ISUP CICs.

 

Circuit Query Message:

Send a CQM (Circuit Query Message) to query for the CIC state. The CQM and CQR (Circuit Query Request) is printed in the Call Tracing. Can query 1 CIC at a time. Cannot query a range of CICs

 

Graceful Out Of Service:

Bring CIC or range of CIC's Out of Service Gracefully. Allow any calls to be released before bringing CIC to an idle state.
