History: Sangoma SMG Product PlanSource of version: 5 (current)The [http://sangoma.editme.com/wanpipe-linux-asterisk-ss7|Sangoma Signal Media Gateway] (SMG) is a set of technologies that augment other media gateway and PABX projects so they can connect to the PSTN for SS7-controlled intermachine trunks (IMT) and SS7 services.
Sangma SMG is composed of the following components: *Linux 2.6 operating system *Sangoma WAn adapter cards and Wanpipe drivers for E1/T1 connectivity *((xmtp2km)) for SS7 MTP2 *((ss7box)) for SS7 MTP3 *((ss7boost)) for SS7 ISUP and SCCP *((sangoma_mgd)) for managing IMT voice circuits with control info from ss7boost *[http://www.pbxfreeware.org/chan_woomera/|chan_woomera] as a point of interface to media gateways *media gateway/pabx (for example, [http://www.asterisk.org|Asterisk] or [http://www.freeswitch.org|FreeSwitch]) !Rev 0.2 (Under Development) --- *((Clustering)) - Multiple SMG platforms operate as a single entity. One or two SS7 links are sufficient to control a growing number of E1/T1 by adding cards and platforms to the cluster. Almost perfect linear growth curve. *A-link support. *ss7box platform redundancy for increased operational safety. !Rev 0.1 (Legacy) --- * Tested with 8 E1 at full capacity on a single platform with a single high performance CPU at 80% utilization with G.711 voice streams. *Voice codec interworking, CPU resource, and memory resource all impact call capacity. *Tested in both ANSI and ITU environments. *SS7 F-link capability with failover/failback support. Multiple linkset and multi-link linkset support. Alternate route support. *See product plans for individual components listed above for more details. |
