1.Simulator, test and demonstration application with multiple BRI ports acting
like an ISDN network. Full inter-connection and features such as CLI etc. Available
with 4, 8 or 16 BRIs. |
| |
2.PRI network simulator available with one or two
ports. Full "B" channel cross-connection.
with 4, 8 or 16 BRIs. |
| |
| 3.ISDN BRI and PRI simulator. Allows testing and
applications such as demonstrating equipment at customer site. Supports
4,8 or 16 BRIs with one or two PRIs. |
| |
| 4.Convert multiple network BRIs into a PRI where
PRIs are unavailable, expensive or not supplied with less than 30 "B" channels.
4, 8 or 16 BRI ports connect to the network. |
| |
| 5.Convert network BRIs into two PRIs which need
fractional PRI access. Greatly reduces installation, rental and deposit
costs. Ability to share and contend for capacity if required. |
| |
| 6.Use multiple BRI access lines to deliver one or
two PRIs as well as local BRI ports. Share network capacity and use low-cost
BRIs lines instead of multiple expensive PRI and BRI. Up to two local PRIs
and a total of 16 BRIs (network and customer-facing). |
| |
| 7.Share a smaller number of network BRIs between
many local PRIs, for example 4 network BRIs can be used by up to 12 local
devices. |
| |
| 8.Share a single network PRI and network BRIs between
a local PRI and multiple BRIs. The network PRI and BRI services could possibly
be from different Carriers giving resilience. |
| |
| 9.Share a single PRI and multiple network BRIs (from
two different Carriers?) between two local PRI devices and multiple BRI
units. Sharing and contention is available. |
| |
| |
| |
 |
|
| |
| 10.Convert a network PRI or fractional PRI into multiple
BRIs. Up to 16 BRIs (32 "B" channels) with 4, 8 and 16 port options. |
|
| 11.Use a single PRI to supply one or two local PRI devices
and 4, 8 or 16 BRI units. |
| |
| 12.Use two PRIs (from different Carriers?) to deliver
local PRI and BRI ports. Least cost routing (LCR) functions are available
in Liberator if two different Carriers are used. |
| |
| 13.Share two different Carriers to supply a single
PRI. Most common application for this configuration is least cost routing
or for applications that require enhanced resilience. |
| |
| 14.Share a single PRI between two local PRI devices.
There is no BRI requirement in this application. |
| |
| 15.Liberator supports Carrier Preselect or Pre-select
least cost routing by adding digits to the dialled number so the calls
can be directed to the lowest-cost operator. |

Patapsco's DB120 provides the ability
to support more PRI and BRI ports as well as supporting other applications
such as ISDN backup. |
