Liberator S ISDN Converter, Splitter, Switch & Concentrator

Liberator S

The Liberator S ISDN Converter, ISDN Splitter, Switch, and Concentrator supports up to 4 E1/T1/PRI interfaces and 0, 4, 8, 12, or 16 BRI ‘S’ interfaces. As standard Liberator ‘S’ can be user configured with either all E1 or all T1 PRI interfaces. Purchasing the optional E1/T1 conversion pack means both E1 and T1 can be supported on the same unit. BRI NT and TE ports can optionally be fitted with Power Failure Relay Protection. BRIs can be set for ETSI (Euro-ISDN) or ANSI (US-ISDN) on a per-port basis and can perform ANSI to ETSI conversion. The unit will connect any port to any port and any ‘B’ channel to any ‘B’ channel without constraint giving full cross-connectivity between all ports, both local and network channels. The intuitive DbLite GUI (supplied) enables fast and simple configuration. All options can be set to tailor the use, connectivity, least cost routing and other advanced features to match the requirements. The flexibility and modularity of the Liberator means it can be put to many varied uses.

Liberator S BRENT Converter

BRENT Converter

The BRENT Converter is based on the Liberator “S” platform and all features on the Liberator “S” are available on the BRENT Converter. The BRENT Converter is a powerful and useful tool for many situations. It is designed to simplify BRENT installations and to provide a more cost effective, reliable and manageable solution for applications where multiple BRENTs are required (for videoconferencing, for example). It also enables BRENTs to use more reliable PRI services, which may also be delivered over fibre to improve security. To ensure more reliable BRENT operation with ISDN in other countries, including the USA, SPIDs etc are handled and there are a number of configuration options to help the BRENTs to function under different conditions and on a huge variety of networks. BRENT can be troublesome and difficult to interoperate with non-UK ISDN services but the Brent Converter assists in overcoming these issues. It also has many flexible features, such as Number Manipulation, which often come in useful in the more unusual applications often associated with BRENTs.

Liberator E - ISDN Converter, ISDN Splitter, Switch, and Concentrator

Liberator E

The Liberator E high reliability ISDN Converter, ISDN Splitter, Switch, and Concentrator supports 8, 16, 24 or 32 PRI/E1/T1 interfaces and Dual load-sharing PSUs. Ability to inter-link Liberator ‘E’ units to support additional PRI ports in a virtual non-blocking single switch. The Liberator models can support up to 32 E1/T1/PRI interfaces via two card types, either 8-port or 16-port cards. The PRI ports on the 8-port card can be user-switched between NT and TE and have Telecoms Approvals for direct connection to the ISDN network. The PRI ports on the 16-port cards are NT only. When mixing an 8-port and a 16-port card the 8-port is always in the lower position. Purchasing the optional E1 T1 conversion pack means both E1 and T1 can be supported on the same unit and this can be selected on a per-port basis. The unit will connect any port to any port and any ‘B’ channel to any ‘B’ channel without constraint, giving full cross-connectivity between all ports, both local and network channels.

ISDN Bri Fibre Optic Modem

ISDN Bri Fibre Optic Modem

The FRM2-BRI/ST2 is an ISDN over fibre modem that enables basic rate ISDN interfaces to be extended over multimode fibre optic cabling. The units are ideal for sensitive data applications that require the use of fibre and have been designed to transport a single ISDN Bri interface over multimode fibre optic cabling. The unit is completely transparent to all ISDN protocols and is simply 'inserted' between the ISDN line and end terminal equipment.

Central Site I-Mux

Central Site I-Mux

The DataBand CSI and ISU range connect high speed serial data devices together using multiple ISDN calls, in effect dialling a high-speed “leased line” between non-ISDN devices. It is ideal for use with videoconference units, MCUs, encryptors (such as KIVs) or any high-speed serial device that needs bandwidth on demand. It aggregates or inverse multiplexes multiple ISDN channels from multiple ISDN PRI interfaces into N*64kbps V.35, RS530, X.21/V.11 and E1 ports. A single CSI (Central Site I-Mux) supports from 1 to 8 ISDN PRIs for network access, and from 8 to 16 serial data ports with data rates of up to 1.024Mbps per port. CSIs can be linked together to form larger systems. Easy to manage and configure, the CSI is an ideal central-site solution for:

  • New Inverse multiplexing and Terminal Adaptor applications
  • Replacement of existing unsupportable legacy platforms
  • Migrate and free-up multiple single port I-Muxes/aggregators at central sites and redeploy them at remote sites

DataBand ISU 512U - I-Mux Service Unit 512k with up to 4 x “U” BRI ISDN ports

DataBand ISU 512U

The DataBand ISU and CSI range connect high speed serial data devices together using multiple ISDN calls, in effect dialling a high-speed “leased line” between non-ISDN devices. The 512U version is available with 2 or 4 x “U” 2-wire Basic Rate ISDN interfaces (common in North America) and can deliver data rates of up to 512kbps. {There is also a version with both 2 x “U” interfaces and 2 “S” TE interfaces which gives added flexibility if unsure of what ISDN services may be available}. Available with 1 or 2 I-Mux serial ports. The ISDN can be partitioned between the 2 ports or access dynamically so 1 port can use all of the ISDN, for example. This gives a great deal of flexibility on potential speeds of different calls. The Cascade option allows the system to be further expanded.

DataBand ISU 512S - I-Mux Service Unit 512k with up to 4 x “S” 4-wire BRI ISDN ports

DataBand ISU 512S

The DataBand ISU and CSI range connect high speed serial data devices together using multiple ISDN calls, in effect dialling a high-speed “leased line” between non-ISDN devices. The 512S version is available with up to 4 x “S” 4-wire Basic Rate ISDN interfaces and can deliver data rates of up to 512kbps. The “S” BRI interfaces can optionally be individually switched between the standard TE presentation (connects to a carrier-delivered service) and NT presentation (acts like a carrier interface and connects to other ISDN equipment). This feature gives added flexibility on service types and means other ISDN devices can also share the network resources. There is also a version with 2 x “U” interfaces and 2 x “S” interfaces which gives added flexibility if unsure of what ISDN services may be available. Available with 1 or 2 I-Mux serial ports. The ISDN can be partitioned between the 2 ports or access dynamically so 1 port can use all of the ISDN, for example. This gives a great deal of flexibility on potential speeds of different calls.
