It has modular construction allowing a basic setup to be expanded as needed by clipping extra modules onto a backplane
The basic Central Control Unit (CCU) starts off as an 8 extension unit, with either analog POTS lines or ISDN line modules available. There is a serial connection that can be used for call logging and configuration. It can either use standard telephones or proprietary feature phones. A special Door Phone may be added on extension 23 and the system may be connected to an electronic lock relay to allow the door to be opened via a Door Phone call. Any extension may be programmed as a PA (Public Address) speaker.
It is the successor to the BT Pathway also made by Lake Communications, which superseded the BT Inspiration which in turn superseded the BT Revelation.

Wiring information
Extensions are 4-Wire hybrids, connect 2 and 5 to A and B on the CCU for standard analogue extensions and 1 and 6 to C and D for digital extensions. There are no connections to 3 and 4.
Miscellaneous information
Current known highest firmware version for the CCU is 915 Current known highest firmware version for the BBM is 189
The BBM module is notoriously unreliable on early versions of the firmware requiring frequent reboots to reconnect to the trunk.
The BBM comes in two versions, a two port and twelve port. Both are to be avoided and best use a VoIP to PSTN trunk converter, such as a Cisco unit.
This unit was manufactured for other markets under the name of "Commander Connect", "Inter-tel Encore CX", "Tellumat Convergence 30 (C30)" & "Mitel 3000"
The Digital Private Network Signalling System (DPNSS) is a network protocol used on digital trunk lines for connecting to PABX. It supports a defined set of inter-networking facilities.
Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the digitalised circuits of the public switched telephone network. Work on the standard began in 1980 at Bell Labs and was formally standardized in 1988 in the CCITT "Red Book". By the time the standard was released, newer networking systems with much greater speeds were available, and ISDN saw relatively little uptake in the wider market. One estimate suggests ISDN use peaked at a worldwide total of 25 million subscribers at a time when 1.3 billion analog lines were in use. ISDN has largely been replaced with digital subscriber line (DSL) systems of much higher performance.
Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for voice calls for the delivery of voice communication sessions over Internet Protocol (IP) networks, such as the Internet.
The public switched telephone network (PSTN) is the aggregate of the world's telephone networks that are operated by national, regional, or local telephony operators. It provides infrastructure and services for public telephony. The PSTN consists of telephone lines, fiber-optic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables interconnected by switching centers, such as central offices, network tandems, and international gateways, which allow telephone users to communicate with each other.
Internode Pty Ltd is an Australian Internet service provider (ISP) that provides NBN broadband services, business-class broadband access, web hosting, co-location, Voice over IP, and a variety of related services. Internode became part of TPG Telecom in July 2020.
Asterisk is a software implementation of a private branch exchange (PBX). In conjunction with suitable telephony hardware interfaces and network applications, Asterisk is used to establish and control telephone calls between telecommunication endpoints such as customary telephone sets, destinations on the public switched telephone network (PSTN) and devices or services on voice over Internet Protocol (VoIP) networks. Its name comes from the asterisk (*) symbol for a signal used in dual-tone multi-frequency (DTMF) dialing.
A business telephone system is a telephone system typically used in business environments, encompassing the range of technology from the key telephone system (KTS) to the private branch exchange (PBX).
The next-generation network (NGN) is a body of key architectural changes in telecommunication core and access networks. The general idea behind the NGN is that one network transports all information and services by encapsulating these into IP packets, similar to those used on the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term all IP is also sometimes used to describe the transformation of formerly telephone-centric networks toward NGN.
Direct inward dialing (DID), also called direct dial-in (DDI) in Europe and Oceania, is a telecommunication service offered by telephone companies to subscribers who operate private branch exchange (PBX) systems. The feature provides service for multiple telephone numbers over one or more analog or digital physical circuits to the PBX, and transmits the dialed telephone number to the PBX so that a PBX extension is directly accessible for an outside caller, possibly by-passing an auto-attendant.
A VoIP phone or IP phone uses voice over IP technologies for placing and transmitting telephone calls over an IP network, such as the Internet. This is in contrast to a standard phone which uses the traditional public switched telephone network (PSTN).
