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It is the successor to the BT Pathway also made by Lake Communications, which superseded the BT Inspiration which in turn superseded the BT Revelation.
On the BT Systems this allows you to connect to BT's VOIP services as trunks and provides the ability to connect VOIP extensions using the V-IP Feature Phone.
The BROADBAND MODULE has the following features:
Wide Area Networking
Local Area Networking - providing a 4 port hub
Wireless Local Area Networking
Multi-user Internet Access
ADSL/Broadband
ISDN
Firewall
VoIP Gateway supporting 2 IP trunks
Management - via serial (v24 interface) or IP
The BROADBAND MODULE PLUS has all the above features but includes a VoIP Gateway with
12 endpoints that can be configured as IP trunks, IP extensions, or any combination of both. It
also supports Unified Messaging.
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.
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"
