Protocol Development


CubeRoot has a reputation of excellence in the field of customised stack development and approval testing. With experience in an extensive range of industry standards and customised protocols, we are confident that we can apply our knowledge to any development.

Our diverse experience covers major developers such as Trillium, Telenetworks, Netbricks, WindRiver as well as our own in house development of stacks from standards.

We have taken several stacks through to full approval at test houses such as KTL and BSI.


Stack development and portation of existing stacks is complimented by our experience in driver development, incorporation of protocols into existing software and automated regression test services.

The following set of case studies is an example of the work we have conducted in the field of protocol stack development. These projects have been conducted on commission for both medium and large companies including Ericsson and Motorola.

ISDN Monitor And Decoder
  • Windows based
  • EuroISDN decoding
  • Filtering of Q.921/Q.931 message types
  • Storage and offline decoding
Time-stamped message flows, custom colour settings. Time capture mode, allowing hours or even days of message analysis.
EuroISDN BRI Stack
  • Fully developed in-house
  • Approved software
  • Custom Call Control
  • Developed to ITU Standards
Fully approved Basic Rate Stack Q.931/Q.921 with multiple TEI support.
Frame Relay Stack Portation
  • Trillium Stack Portation (Q.933 & LMI/Q.922)
  • Frame Relay/ATM interworking
  • Custom Call Control designed and implemented
  • In depth knowledge of PVC/SVC procedures
Portation of Frame Relay into ATM backbone switch. A complex Call control module was designed to control and interface to the existing software architecture (CPSA). A web based interface was designed and implemented using Ericsson's Erlang language.
ISDN CAS Development
  • Linux Based Media Gateway development
  • Multiple Variant Protocol support
  • State Machine Design and Implementation
  • Testing to standard Telecomm equipment
Customer requirement driven project with the development of multiple CAS protocol stacks, integrated into a media gateway. Fully tested and documented inhouse.
DASS-2 PRI Stack Portation
  • Telenetworks Stack Portation
  • Approval to BSI Standards
Custom stack written to interface to existing customer software. Taken to full BSI approvals and testing. Extensive documentation was written for the project that enabled customers to expand the software features in the future.
EuroISDN PRI Stack Portation
  • Telenetworks Stack Portation
  • Remote Data Backup Solution
  • Short time-to-market project
EuroISDN stack ported onto customer platform for data backup solution. This development was completed in a short timeframe for time-to-market window. The software was then taken to KTL test labs for full approvals.
