Overview
Follow the steps below to configure two Excel platforms for interworking. These steps assume knowledge of SS7 and IP configuration.
The following term is used below.
Universal Flavor - Indicates that the Universal Protocol is not using any user defined TLVs to communicate any network-side protocol information which is not represented in the Universal Protocol specifications.
1. Assign the Logical Node ID.
2. De-assign spans.
3. Send the Product License Download message for the appropriate license (for example SIP).
4. Assign the IP Network Interface card’s spans and channels.
5. Configure interworking for all the designated SS7 CICs by setting the L4 Host Interworking configuration byte 0x0A as follows:
00 17 00 D7 00 00 FF 01 02 0D 03 00 01 00 0D 03 00 05 17 00 61 01 01 0A 01
Where:
00 61 = L4 Channel Management
01 = Entity
01 = Number of configuration bytes
0A = L4 Host Interworking
01 = Enable
See CH - Channel Management (0x61) in the API Developer’s Guide: Overview for more detail.
6. Configure Layer 4 interworking conversion from SS7 to Universal format by setting configuration bytes for Host/Network Protocol ID and flavor in the L4 Interworking component 0x84.
00 1D 00 D7 00 00 FF 01 02 0D 03 00 01 00 0D 03 00 05 17 00 84 01 04 03 01 04 02 14 05 15 01
Where:
00 84 = L4 Interworking Component
01 = Entity
04 = Number of Configuration Bytes
03 = Local Network Protocol ID
01 = SS7
04 = Local Network Protocol Flavor
14 = Host Protocol ID (host interface to mimic for host interworking)
05 = Universal Protocol
15 = Host Protocol Flavor (host interface to mimic for host interworking)
01 = Universal Flavor (indicates that the Universal Protocol is not using any user defined TLVs to communicate any network side protocol information which is not represented in the Universal Protocol specifications.)
See PPL Component for Interworking (0x84) in the API Developer’s Guide: Overview for more detail.
7. Configure the SS7 stack, link set, links, routes, and CICs.
8. Send the route tables.
9. Bring spans, SS7 links, and channels in service.
10. Using the VoIP Protocol Configure 0x00EE configure the appropriate TLVs to enable SIP, UPDF tunneling, and remote host (set as Excel platform 2).
1. Assign Logical Node ID.
2. Deassign spans.
3. Send the Product License Download message for the appropriate license (for example SIP).
4. Configure interworking for all the designated SS7 CICs by setting the L4 Host Interworking configuration byte 0x0A as follows:
00 17 00 D7 00 00 FF 01 02 0D 03 00 01 00 0D 03 00 05 17 00 61 01 01 0A 01
5. Configure Layer 4 interworking conversion from SS7 to Universal format by setting the configuration bytes for Host/Network Protocol ID and flavor in the L4 Interworking component 0x84.
00 1D 00 D7 00 00 FF 01 02 0D 03 00 01 00 0D 03 00 05 17 00 84 01 04 03 01 04 02 14 05 15 01
6. Configure the SS7 stack, link set, links, route, and CICs.
7. Send route tables.
8. Bring spans, SS7 links, and channels in service.
9. Using the VoIP Protocol Configure (0x00EE) message configure the appropriate TLVs to enable SIP, UPDF tunneling, and remote host.
