Protocols and approvals
Worldwide IP and tdM protocols for applications using boards and software from Aculab
Aculab's protocol coverage extends to the broadest range of worldwide call control and signalling protocols with appropriate, host independent regulatory approvals. the list includes many different national and international variants of Signalling System Number 7 (SS7), CAS and ISDN (including Q.931, Q.SIG and DPNSS), for operation over E1 and T1 trunks on our tdM boards. In addition, for IP telephony and VoIP applications, Aculab offers H.323 and SIP stacks for use with our IP and media processing boards.
Combined protocols
Many applications require voice board or IP-based media processing functionality, such as record, playback, DTMF handling, wideband audio conferencing, encoding/transcoding and T.38 fax. All these essential functions and more are available with Aculab's Prosody X IP or DSP boards, which can be combined with any protocol, including SIP and SS7, to deliver powerful, cost-effective, telecoms server-based solutions.
In addition, offering the same core functionality, Prosody S, Aculab's advanced HMP, offers a viable alternative to using IP boards for telco and enterprise applications or service delivery platforms, bringing granular scalability and cost-efficiencies to those familiar with traditional, board-based designs.
Obtaining the software
With the exception of SIGtrAN and Prosody S, which are licensed, all protocols, including SIP and C7, are freely available via a software download utility for use with all of Aculab's board hardware. Developers can simply collect the protocol firmware, free of charge, when they need it, gaining a distinct advantage in terms of system cost and value per channel.

Regulatory approvals
Aculab has obtained many country specific, host independent regulatory approvals, such that Aculab's boards can be integrated into PC or server-based solutions without further telecom approvals being needed. In regions where this option is not available, Aculab has experience to offer in support of users seeking system level type approvals.
To discuss your requirements, contact your Account Manager or send an email to sales@aculab.com and one of our representatives will get right back to you.
Summary detail
A detailed summary of the available approvals and protocol information can be viewed as a PDF file. Please note that a number of protocols are used throughout the world, (like DPNSS, Q.SIG and SS7) and are indexed as 'Worldwide' in the tables.

| Notes: 1. A DSP 65 module is required for DTMF or CAS tone signalling with E1/T1 PCI and Passive monitor PCI boards. A PMXC is needed for SS7 and DTMF or CAS tone signalling with Prosody X variants. 2. Protocols marked ' ' in the table are compatible with Aculab's Passive Monitor products based upon the E1/T1 PCI and cPCI boards. In the case of Canada and the USA, the applicable protocols are T1 Q.931/Q.932-based ISDN protocols only. Aculab's 'p-monitor' firmware is required.3. Aculab's R2T1 firmware provides a generic MFC R2 protocol stack, which uses switches to establish specific national or signalling variants. See the individual protocol release notes available via the Aculab installation tool (AIT). 4. Many CAS protocols provide for selection of either decadic (dial pulse), DTMF or MFR1 or MFC R2 register signalling and a number of line signalling methods. See the individual protocol release notes. 5. the majority of protocols are balanced, meaning that the same protocol may be used at both user and network ends of a link. In some cases user and network ends are established by switches in the firmware. Some protocols are provided by means of separate firmware for user and network ends. See the individual protocol release notes. 6. Some protocols offer both DDI and non-DDI options. See the individual protocol release notes. 7. In some cases the source specification documentation is less than thorough in its treatment of the protocol, leaving operations open to interpretation. Aculab is grateful for any feedback regarding the use of any listed protocol. 8. If you cannot find the protocol you need listed here, we may be able to help, as often, particularly with CAS protocols, an existing variant can prove viable. Aculab's generic MFC R2 stack often proves suitable for use even in countries where it has not already been validated for use against a specification. Aculab are able to compare an existing protocol stack against your specification, or alternatively may be able to produce the required variant for you. Please contact your Account Manager or email sales@aculab.com to discuss your requirements. 9. Developers looking to use 'host independent' approved Aculab products in their complete CT systems should not require further telecoms approval for that system prior to network connection. | |||||

| Notes: 1. A DSP 65 module is required for DTMF or CAS tone signalling with E1/T1 PCI and Passive monitor PCI boards. A PMXC is needed for SS7 and DTMF or CAS tone signalling with Prosody X variants. 2. Protocols marked ' ' in the table are compatible with Aculab's Passive Monitor products based upon the E1/T1 PCI and cPCI boards. In the case of Canada and the USA, the applicable protocols are T1 Q.931/Q.932-based ISDN protocols only. Aculab's 'p-monitor' firmware is required.3. Aculab's R2T1 firmware provides a generic MFC R2 protocol stack, which uses switches to establish specific national or signalling variants. See the individual protocol release notes available via the Aculab installation tool (AIT). 4. Many CAS protocols provide for selection of either decadic (dial pulse), DTMF or MFR1 or MFC R2 register signalling and a number of line signalling methods. See the individual protocol release notes. 5. the majority of protocols are balanced, meaning that the same protocol may be used at both user and network ends of a link. In some cases user and network ends are established by switches in the firmware. Some protocols are provided by means of separate firmware for user and network ends. See the individual protocol release notes. 6. Some protocols offer both DDI and non-DDI options. See the individual protocol release notes. 7. In some cases the source specification documentation is less than thorough in its treatment of the protocol, leaving operations open to interpretation. Aculab is grateful for any feedback regarding the use of any listed protocol. 8. If you cannot find the protocol you need listed here, we may be able to help, as often, particularly with CAS protocols, an existing variant can prove viable. Aculab's generic MFC R2 stack often proves suitable for use even in countries where it has not already been validated for use against a specification. Aculab are able to compare an existing protocol stack against your specification, or alternatively may be able to produce the required variant for you. Please contact your Account Manager or email sales@aculab.com to discuss your requirements. 9. Developers looking to use 'host independent' approved Aculab products in their complete CT systems should not require further telecoms approval for that system prior to network connection. | |||||
