ISUP Group - JTISUP

This pane defines the configuration for a group of ISUP channels. The contents of the pane will vary depending on whether the associated SS7 Stack configured in the OPC-DPC field is an ANSI, ITU, or JTISUP stack.

 

For Information Regarding the ISUP Group with an ANSI stack selected in the OPC-DPC field, refer to the ISUP Group - ANSI

For Information Regarding the ISUP Group with an ITU stack selected in the OPC-DPC field, refer to the ISUP Group - ITU

Field Descriptions:

OPC - DPC

This field has a drop-down list populated with OPC-DPC combinations from previously configured SS7 Stack (OPC) and SS7 Route (DPC) configurations.

 

Glare Rule

Indicates how simultaneous incoming and outgoing seizures of the same SS7 channel are resolved.

Drop Outgoing Call - The incoming seizure is denied.

Drop Incoming Call - The outgoing seizure is denied.

Odd/Even - The incoming seizure is denied if:

> The OPC value is less than the DPC value and the CIC number is odd or,

> The OPC value is greater than the DPC value and the CIC number is even (ITU-T Recommendation Q.767).

 

Incoming Continuity Check

Configures the behavior when receiving an IAM with Continuity Check required on this circuit.

Wait for COT (default) - Wait for the COT before sending the INVITE or Setup (Outgoing IP channel groups).

Do not wait for COT - Propagate the IAM with 'Continuity check required on previous circuit' (Outgoing SS7 channel groups).

 

Out Continuity Check

This field indicates how frequently outgoing calls on this SS7 channel undergo an automatic continuity check.

 

None (Default) - No Continuity Checks Performed

1:xx - One out of every X calls undergoes a Continuity Check

1:02 - One of every 2 calls undergoes a Continuity Check.

1:03 - One of every 3 calls undergoes a Continuity Check.

1:04 - One of every 4 calls undergoes a Continuity Check.

1:05 - One of every 5 calls undergoes a Continuity Check.

1:06 - One of every 6 calls undergoes a Continuity Check.

1:07 - One of every 7 calls undergoes a Continuity Check.

1:08 - One of every 8 calls undergoes a Continuity Check.

1:09 - One of every 9 calls undergoes a Continuity Check.

1:10 - One of every 10 calls undergoes a Continuity Check.

1:11 - One of every 11 calls undergoes a Continuity Check.

1:12 - One of every 12 calls undergoes a Continuity Check.

1:13 - One of every 13 calls undergoes a Continuity Check.

1:14 - One of every 14 calls undergoes a Continuity Check.

1:15 - One of every 15 calls undergoes a Continuity Check.

1:16 - One of every 16 calls undergoes a Continuity Check.

 

Satellite Circuit

This field indicates if this SS7 channel makes use of a satellite facility.

 

No (Default)

Yes

 

CIC Service Rule

Indicates which SS7 message is sent when an SS7 stack on the 2020 IMG takes an SS7 channel out-of-service.

Block - The SS7 stack sends an SS7 Blocking (BLO) message. The SS7 stack will then send an SS7 Unblocking (UBL) message when the 2020 IMG puts the SS7 channel back in service.

No Bloc - The SS7 stack does not send SS7 message. This stack will send an SS7 Reset Circuit (RSC) message when the 2020 IMG puts this SS7 channel back in service.

No Action - The SS7 stack does not send an SS7 message.

 

Hop Counter

Indicates the number of switches that can have processed a call before the call is dropped.

Off (Default) - Feature is Disabled. Switch will not reject call.

01-31 - Select from drop down list the number of switches that can process the call before call is dropped.

Echo Suppression

Echo Suppression is designed to eliminate echo signals in one direction caused by signals in the other direction. Helps prevent the individual talking on a telephone line from hearing his or her own voice.

Echo Suppressor Not Present (Default) - Echo Suppression is disabled.

Echo Suppressor Present - Echo Suppression is enabled

LNP Routing Enable

Use this field to enable or disable Local Number Portability routing.

 

Disable (Default)

Enable

 

Refer to the Local Number Portability (LNP) topic for more information.

 

Link OOS Handling

Disable (Default) - Functionality is same as previous software. If Signaling Link goes Out Of Service, then the associated CIC's will go Out Of Service as well.

Enable - If signaling link goes Out Of Service all associated CIC's which are in the idle state will go Out Of Service. If any CIC's are in either the ringing or connected state the CIC's will not go Out Of Service until a later subsequent condition occurs. See SS7 Link OOS Handling for more information on configuration and functionality.

 

Layer 3 Route Type

MTP3 - Defaults to MTP3 and cannot be modified
