The Pulse product line of Voice Signaling Converters allow any organization, service provider or agency to address the connection of legacy voice equipment to newer standards. Whatever your reason or need to convert from one type of voice signaling conversion to another, Pulse has your solution.

We work with most of the major legacy voice signaling protocols such as R2, E&M, Qsig, ISDN PRI, SS7 and C7. Many others are also available for special applications

The R2 Signaling Protocol has been used around the world since the 1960s.  The R2 protocol is still heavily used in Europe, Latin American, Australia and Asia. This signaling is based on the CAS (channel associated signaling) protocol which means the signaling is contained in each timeslot of voice.

The SS7/C7 Signaling Protocol is the most common standard around the world.  The SS7/C7 protocol defines the procedures and protocol by which network elements in the public switched telephone network (PSTN) exchange information over a digital signaling network to effect wireless (cellular) and wireline call setup, routing and control .

GTW-2200:  This device allows conversion from SS7/C7 to SIP VoIP. Supports E1, T1, T3 or STM-1 . Up to 64 ports of conversion. AC or DC Power.

The ISDN Signaling Protocol has replaced many R2 voice circuits.  The ISDN protocol operates over standard telephone wires supporting voice, video and or/data. The protocol consist of BRI or PRI have B channels that carry the voice or data and D channels for the signaling.

SP-201:  This device allows conversion from ISDN to R1, DTMF or SS7/C7 signaling. Supports E1 and/or T1. A-law to Mu-law conversion. Dual or four span conversion. AC or DC Power.

SP-230:  This device allows conversion from ISDN to SS7/C7 to R1 or DTMF signaling. Supports E1 and/or T1. A-law to Mu-law conversion. Up to 48 span high density conversion. AC or DC Redundant Power.

NC-AD300D:  This device allows conversion from ISDN to SS7/C7, Qsig, V5.2 signaling. Supports E1. Up to 8 span high density conversion. AC or DC Power.

NC-AD300X:  This device allows conversion from R2, ETSI PRI, Qsig, V5.2, C7 , SS7 signaling or Analog FXO/FXS. Supports E1. Up to 50 span high density conversion. AC or DC Power.

Liberator S:  This device allows conversion from PRI to BRI ISDN. Up to 4 PRI and 0,4,8,12 or 16 BRI high density conversion. AC or DC Power.

GWT-2200:  This device allows conversion from ISDN to SIP VoIP. Supports E1, T1, T3 or STM-1 . Up to 64 ports of conversion. AC or DC Power.

The GSM Signaling Protocol is the standard for cellular service around the world.  The GSM protocol operates over 2G and 3G standards with millions of cell phones. There are many purposes for converting GSM to SIP, H.323 or ISDN since cost savings are obtained.

MV-Series:  This device allows conversion from GSM or CDMA 2000 to SIP signaling. Supports 2G and 3G Cellular and  VoIP. Supports up to 8 ports. AC Power.

HG-Series:  This device allows conversion from GSM to SIP, H.323 or ISDN signaling. Supports 2G Cellular, VoIP, E1 and/or T1. Supports up to 72 ports and/or 2xE1/T1. AC Power.

PBX Signaling Protocols for their attached digital telephones are proprietary.  The digital handsets for most all digital PBX or telephone systems are not compatible with today's voice equipment, gateways or IP PBXs. Pulse has products that allows them to be sent over standard IP/Internet or be used with todays IP PBX systems.

Portico:  This device allows conversion from proprietary PBX signaling protocols to SIP voip. Reuse your digital telephone sets with your new IP PBX, no need for users to relearn new phones. Supports up to 24 digital telephones from manufacturers like Avaya, Nortel, Alcatel, Panasonic, Siemens, NEC and Toshiba. AC or DC Power.

Extender:  This device allows conversion from proprietary PBX digital station ports to IP.  This allows for the extension digital telephones across the street or around the world. Supports up to 24 digital telephones from manufacturers like Avaya, Nortel, Alcatel, Panasonic, Siemens, NEC and Toshiba. AC or DC Power.

X.25 signaling protocol was used widely in the 1980's. X.25 is an ITU-T standard protocol suite for packet switched wide area network (WAN) communication. An X.25 WAN consists of packet-switching exchange (PSE) nodes as the networking hardware, and leased lines, Plain old telephone service connections or ISDN connections as physical links. X.25 is a family of protocols that was used especially during the 1980s by telecommunications companies and in financial transaction systems such as automated teller machines. X.25 was originally defined by the International Telegraph and Telephone Consultative Committee (CCITT, now ITU-T) in a series of drafts and finalized in a publication known as The Orange Book in 1976.

X.25 is today to a large extent replaced by less complex protocols, especially the Internet protocol/span> (IP) although some telephone operators offer X.25-based communication via the signaling (D) channel of ISDN lines. There is still a need to provide legacy conversion.

Farlinx:  The FarLinX X25 Gateway is the answer for handling all your X.25 to TCP/IP migration requirements. Featuring routing between TCP and X.25, TCP and XOT, X.25 and XOT, data conversion,, a Triple-X PAD, Host PAD, an extension for special POS protocols and even an X.25 switch all at a very affordable cost, the FarLinX X25 Gateway fits the bill for TCP/IP to X.25 interconnection
