IMG 1010 - SS7 Functionality Specifications 1010 and 1004

Overview

Feature F-1446 'SS7 Stacks on the IMG 1004' allows SS7 Stacks to be configured on the Sangoma®IMG 1004. Since the inception of the IMG 1004 there has been a slow progression of SS7 functionality. Initially SS7 was not supported then in software version 10.5.1 feature F-1406 was added which now allowed the IMG 1004 to be configured as a remote SS7 node and was able to terminate up to 4 links. Now in software version 10.5.3 the ability to configure SS7 stacks is now supported. The addition of this feature allows the IMG 1004 to have the SS7 functionality of the IMG 1010 with limitations. See the links in the Related Topics Heading below for information on the functionality and limitation of SS7 on the IMG 1004. Information on configuration etc. can be found in the SS7 configuration section of this WebHelp (Configuration > Signaling > SS7_10.5.1+). Configuration is accomplished in the same manner as the IMG 1010.

SS7 Redundancy

Supported

Supported

SS7 Stacks

  • 32 Stacks per GCEMS (Software 10.5.3 SP7+)

  • 16 Stacks per GCEMS

  • 4 Stacks within each Logical Node Group

  • 32 Stacks per GCEMS (Software 10.5.3 SP7+)

  • 16 Stacks per GCEMS

  • 4 Stacks within each Logical Node Group

SS7 Links

  • Up to 128 links can be created within a logical node group.

  • Up to 64 links may be terminated on an individual IMG 1010.

*Redundancy is not a factor on number of links created within logical node group.

  • Up to 4 links may be terminated on an individual IMG 1004.

  • Up to 8 links total may be configured in a logical node group. Logical node group for IMG 1004 has a max number of two IMG 1004's

*Redundancy is not a factor on number of links created within logical node group.

SS7 Routes

  • 512 Routes to 128 Destinations per Logical Node Group.

  • 32 Routes to 8 Destinations per Logical IMG Node Group.

CICs

  • 768 CICs per Physical T1 IMG within logical node group. (32 Interfaces * 24 Channels)

  • 744 CICs per Physical E1 IMG within logical node group. (24 Interfaces * 31 Channels)

At least one channel is needed for SS7 signaling link. Therefore, the functional maximum on at least one node is 767 CICs

  • 128 CICs (Single IMG 1004 logical node group)

  • 256 CICs (Logical node group for IMG 1004 has a max number of two IMG 1004's).

At least one channel is needed for an SS7 signaling link. Therefore, the functional maximums are actually (127 CICs / 255 CICs)

CIC Groups

  • 512 ISUP Groups per Logical IMG Node Group when SS7 signaling is configured on IMG 1010.

  • 16 ISUP Groups per Logical IMG Node Group when SS7 signaling is configured on IMG 1004.

Node Group Membership

  • An IMG 1010 SS7 Node Group many contain up to 32 nodes (either IMG 1010 or IMG 1004).

  • At least one IMG 1010 node must be the designated SS7 Primary node.

  • Optionally, a second IMG 1010 node may be designated the SS7 Secondary node for SS7 redundancy.

  • An IMG 1004 SS7 Node Group may contain up to two IMG 1004 nodes.

  • At least one node must be the designated SS7 Primary node.

  • Optionally, the second node may be designated as a SS7 Secondary node for SS7 redundancy.

 

Additional Functionality:

  • As displayed in the table above, an IMG 1004 configured as a SS7 Server can control one remote node with CIC's.

  • If configuring SS7 redundancy the IMG 1004 configured as an SS7 server (Primary) will allow only the SS7 secondary node to be configured. No remote nodes can be configured in this situation.

  • When configuring SS7 Redundancy the IMG 1004 supports up to 8 links. Four links can be configured on the Primary SS7 Node and Four links can be configured on the Secondary SS7 Node.

  • The IMG 1004 supports SIP-T functionality.

  • The IMG 1004 DOES NOT support SS7 M3UA functionality.

  • The IMG 1004 DOES NOT support SS7 SCCP/TCAP traffic.

  • No labels
