Telscale SS7 card is a small DSP-based computer, designed to be used with OpenSigtran software. It can be ether plugged inside a server or just powered with +5V DC.
Telscale card runs uClinux, has 2 synchronous TDM interfaces (E1 or T1) and 2 Ethernet ones.
The card is capable of acting as ether a signaling gateway or a probe.
Depending on the volumes, Telscale SS7 card can be ordered in another form-factors.
When used as a set of Signaling Gateways, a card is connected to PLMN via a couple of G.703 E1 or T1 interfaces, which can be populated with 64k (low speed) or 2M (high speed) signaling links.
The multiplexing sublayer distributes time slots with signaling between various SS7 stack instances that are runing inside a card as independent uClinux applications. Initial version of M3UA stack can be found here.
Card is capable of monitoring 2 G.703 E1 or T1 interfaces and can be assumed as a cost-effective probe for various purposes.
It can be a part of SS7 monitoring/fraud detection/welcome-sms etc solution or can convert a PC with Wireshark into protocol analyzer, providing traces like USSD payload test.
As Telscale SS7 card is a stand-alone computer that interfaces the World via IP,
