Liberator S Technical Specification 1. Overview The Liberator models detailed within this document support up to 4 PRI interfaces and 0, 4, 8, 12, or 16 BRI ‘S’ interfaces. A standard Liberator ‘S’ can be user configured with all PRI interfaces the same. The BRI ports are supplied as standard to be NT presentation (simulates a network and connects to CPE). Software enables BRIs to be user-configured as NT or TE ISDN Converter, ISDN Splitter, Switch, and Concentrator (simulates CPE and connects to a network) in blocks of 4.

Any call can be routed to a Group of ports or ‘hunt-group’. Multiple devices can be configured to accept calls dialling to a range of numbers and the calls can be routed to a Group in a variety of ways (sequential, always the lowest available port etc). Incoming calls can be automatically rerouted to alternate preprogrammed destinations if the main number is busy or unavailable, or after a set time (1-20 seconds). Liberator is configured and managed by Transition’s DbManager. 3.4 Redirection on ‘Busy’ or ‘Unavailable’ Incoming calls can be automatically rerouted to alternate preprogrammed DbManager is an intuitive GUI which supports multiple real-time workstations. Versions are available which can be configured for the smallest installation, or up to many thousands of devices. Configuration/management sessions can be established remotely via an ISDN call or locally through the unit’s LAN/Ethernet port or the RJ serial port. SNMP Traps & Alarms are supported as is a call analysis tool. numbers, Groups or ports if the main number or port is unavailable. This gives 3. Ports, inter-connectivity and routing the ability to automatically switch to backup or standby device for resilience purposes. 3.1 Ports, Channels and Groups Liberator employs a simple system where BRI and PRI ports or individual ‘B’ Liberator supports a Secondary and Tertiary destination or Routing Profile. channels can be allocated to one or more customer named “Groups”. If an out-going call to the ISDN network cannot be established (user or network busy, for example), Liberator can automatically redial via other network ports These Groups form the basis of all configurations, making it fast, simple and without the end user having to take any action. The same can be done for intuitive to your applications. As an example you can refer to a Group of 4 BRI incoming calls switching between local devices. 3.5 Call Deflection Some carriers support the “Call Deflection” service. With Liberator calls can be automatically diverted to a different destination, without using any local ISDN channels, based on a number of criteria including DDI number, time-of-day, and/ or no answer. 3.6 Nailed Calls Timeslots or ‘B’ channel capacity can be established on behalf of devices which are unable to handle dialling protocols. For example, Liberator can provide capacity for non-switched Fractional E1 and T1 circuits. These ‘Nailed’ calls can be configured as temporary or permanent, giving the ability to profile capacity to match needs. ports as ‘Video 1’ and subsequently use this term on all routing parameters. 3.7 Channel Reservation and Scheduling This features has the ability to change and structure profiles in an efficient way ‘Hunt Groups’ or ‘rotaries’ are as easy to establish. and to vary them if your routing or capacity requirements change during the day or week. 3.2 Call Routing Calls can be routed on the number dialled, the Time-of day sub-address, CLI, Call Type, originating port, time- A Group can reserve a number of channels based on the time of day. of-day or a combination of the above. Whatever your routing requirements; Liberator can help. A Group can also be configured to have a Minimum and Maximum number of destination channels available and reserved for the Group’s use. 3.3 Cross-Connection Any ‘B’ channel can be connected to any other This facility gives flexibility when allocating network access to different devices, allowing each to have a reserved minimum capacity available for immediate use.

Minnetonka, MN 55343 USA http://www.transition.com PAGE 2 Setting the maximum capacity means the ISDN devices can share and contend Liberator normally passes the tones transparently between ISDN points but for the remaining ‘B’ channels yet any device cannot take an unfair proportion. this is not always possible in all instances, such as some least-cost routing applications, if there is no network at all, or in certain other circumstances The Maximum and Minimum access rates can be varied based on day and such as when Liberator cannot make a final routing decision until the number time. Up to eight different profile schedules can be configured per Group. If any is dialled. In these instances, Liberator can be configured to generate dial, ring, schedules overlap, a warning is given. busy, N/U tones itself. 3.8 Least-Cost-Routing 3.11 CLI Generation A number of options are available to assist with selecting the best route. Liberator is able to generate a CLI field. The number of the CLI can be programmed for individual ports or calling numbers. Calls beginning or ending with particular numbers can be routed to a specific Group or ‘B’ channel. Additional Ports can be configured as secondary/tertiary destinations should the preferred Port(s) be busy or unavailable. Liberator has the ability to convert or translate any incoming or outgoing number into any other number, to add/remove leading, middle and trailing digits. See below ‘Number Translation’. 4. General 3.9 Number Translation or Conversion 4.1 Clocking Any incoming dialled number can be converted by Liberator and presented on Software-selectable clock source using any PRI port any BRI NT interface, or any ISDN interface.

Destination Groups, together with Secondary and Tertiary destinations and number/CLI Any PRI port and any NT BRI conversion. port can be used to source clock. Automatic switch-over when a clock is lost/recovered with no impact on user traffic. 4.2 Real-Time Clock Internal battery-backed real-time clock for Event Log time-stamps and For example an incoming call to 12345 may be converted to 98765 because the debugging purposes. original extension at 12345 has moved onto a VoIP gateway on a different ISDN PRI and now the users has a different DDI number. 4.3 Events Up to 5000 Events are held within the Liberator in NV RAM on a FIFO basis Events Liberator can convert/add/delete leading digits, digits in the middle of numbers include all call information such as port dialling, number dialled, subaddress, and/or trailing digits. It can also manipulate subaddresses and CLIs. time of call and time of call clear-down, time of incoming call and to which port and if there is a CLI attached, time of clear-down and which ‘end’ cleared. All of this flexibility is not required by all, but if you should need it, it is easy to use and configure. Events can be reported automatically to the DbManager or other tools via an ISDN call, the local Console port or across the LAN. This can be on a timed schedule or when the Event Log reaches 90%. Once Events are successfully reported to the DbManager the log is cleared. DbManager can also access the logs and download them when required. DbManager writes all Events and Alarms to a flat .csv file in real-time and this file can be manipulated by external tools to format and extract information, for example for billing. 3.10 Tone Generation 4.4 Routing and Prioritisation Summary Windows Transition Networks, Inc. tel: 952.941.7600 / 800.526.9267 ©2011 Transition Networks, Inc.
