ISDN Simulator General FAQs -Please see here for technical FAQs

Q1. Does Liberator Simulator support BRI TE presentations so it connects to a BRI network?

No, all ISDN connections on the Liberator Simulator are NT. If you require TE interfaces please refer to the Liberator S product range. Back to top

Q2. Does Liberator Simulator support USA-based PRI 23 “B” channels?

Yes, Liberator supports T1 ISDN with various switch options as well as US-based BRIs. All are software configured and the BRIs can support dual SPIDs and dual TEIs. Liberator is also capable of converting between E1/T1 and US/Euro BRIs in many different combinations. Back to top

Q3. Can Liberator Simulator route calls according to the number dialled (DDI)?

Yes, Liberator Simulator has a very powerful routing engine. It is possible to configure multiple routing table entries that define the profile of a specific call and where that call should be routed. Routing can be performed on incoming port number, DDI number, CLI number, Sub addressing, call type (3Khz voice, unrestricted data, video etc) or a combination of all these options. Back to top

Q4. Can Liberator Simulator route calls according to Calling Line Identifier (CLI)?

Yes, Liberator Simulator has a very powerful routing engine. It is possible to configure multiple routing table entries that define the profile of a specific call and where that call should be routed. Routing can be performed on incoming port number, DDI number, CLI number, Sub addressing, call type (3Khz voice, unrestricted data, video etc) or a combination of all these options. Back to top

Q5. Can I route calls based on Call type (3Khz Audio, Unrestricted Data, Video etc)?

Yes, Liberator Simulator has a very powerful routing engine. It is possible to configure multiple routing table entries that define the profile of a specific call and where that call should be routed. Routing can be performed on incoming port number, DDI number, CLI number, Sub addressing, call type (3Khz voice, unrestricted data, video etc) or a combination of all these options. Back to top

Q6. Can I use Liberator Simulator as a drop & insert mux?

No, the Liberator Simulator does not support G703/G704 interfaces. If you require D&I functionality please refer to the Liberator "S" product range. Back to top

Q7. Can I change Routing profiles according to Time of Day?

Yes, Liberator Simulator offers ToD configuration for active profiles. You may wish to route calls in one manner during the day with the ability to route to another destination over night. Back to top

Q8. Can I use Liberator Simulator to manipulate dialled number strings?

Yes, Liberator Simulator has a powerful call conversion engine. This allows modification/ addition of digits to the DDI/CLI and SubAddress fields. Back to top

Q9. Can I “Bar” certain numbers?

Yes, Liberator Simulator offers a call baring facility. It is possible to define certain call profiles which you do not want routed. Back to top

Q10. Can I route calls to an alternative destination?

Yes, Liberator Simulator can have a Primary, Secondary and Tertiary destination configured for each routing profile. Should the call not be routed to the Primary it will automatically try the other two destinations. The re-route facility relies on the call remaining active to allow sufficient time for re-routing.

Q11.What ISDN standards does Liberator Simulator support?

Liberator Simulator currently supports ETSI Q.931 Euro-ISDN and ANSI PRI. Various T1 switch options are available. ISDN interfaces are all NT (looks like a network) "S" interfaces with optional Power Feed. Liberator supports dual SPIDs and other ANSI based parameters. Back to top

Q12. Can Liberator Simulator convert between E1 and T1?

Yes. Liberator Simulator can optionally convert between E1 PRI and T1 PRI. Additionally BRI conversion from ETSI to ANSI is also available. Also see Patapsco's Liberator "C" which is specifically designed for E1-T1 conversion. Back to top

Q13. Is there an upgrade path?

There is no upgrade path for the Liberator Simulator. Please ensure you purchase the correct quantity of ports at procurement. For upgradeable devices please refer to the Liberator S product range. Software upgrades can be done locally or remotely with code loaded to an offline FLASH sector which can be switched to at any time.
