The SP201-SA, a member of the SignalPath™ Signaling Gateway product line, addresses the need for a low-cost product that is universally compatible with most enterprise and customer premise PBXs, IP-PBXs, IP video conferencing, media gateways, and multi-service access devices. The compact SP201-SA desktop unit, which supports CAS (R1, R2, DTMF) and ETSI and NI2 ISDN, is capable of carrying traffic over T1/E1 trunks via standard BNC or RJ48 connections.

The SP201-SA was developed as a PBX solution for both carrier and enterprise customers. With its low cost, expanded feature set, and small footprint, the SP201-SA will attract the business of enterprise Customer Premises Equipment (CPE) vendors who want to establish ISDN to legacy protocol network connections in regions they are currently unable to service due to deficiencies in their networks' signaling capabilities.
