The Liberator S
ISDN converter, switch, concentrator and simulator

Promptus Liberator S 

The Liberator "S" supports up to 3 E1/T1/PRI interfaces and either 0, 4, 8, or 16 BRI 'S' or "U" 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.

 

The BRI ports can be ordered as NT (simulates a network and connects to CPE) or TE (simulates CPE and connects to a network) in blocks of 4, 8 or 16. NT and TE BRIs can be populated within the same unit. Options also are available for Te and NT PRI presentations.

 

The unit will connect any port to any port and any 'B' channel to any 'B' channel giving full cross-connectivity between all local ports and network channels.

 

Through the intuitive GUI (supplied), different options can be set to tailor the use, connectivity, least cost routing and other advanced features.

- Optional Terminal Power-Feed with external 40VDC supply for NT ports. Provides 40V 1W to ISDN BRI devices

 

 

Control Ports

• RJ11: Asynchronous, 8 data, 1 stop bit, no parity, 18kbps to 64kbps
• Ethernet RJ45: 10/100BaseT
• Password protection on both ports

 

 

Indicators

• Each PRI has 2 associated LEDs to indicate Layer 1, 2 and 3 status
• Each BRI has 2 associated LEDs, 1 for each 'B' channel
• LAN:
- COL: to indicate data collisions on LAN 
- ACT: to indicate activity on LAN
- 100: to indicate 100BaseT connectivity
• PWR: to indicate power
• RUN: to indicate operational status 

 

 

Relays

• Interfaces PRI21 and PRI22 are Power Failure Relay protected 
• On power-loss, a critical failure or under operator control, the relays close forming a metalic path between the two interfaces

 

 

Management

• Central Management via DBManager
• Configuration/management sessions can be established remotely via an ISDN call or locally through one of the Control Ports (Asynchronous RJ11 or Ethernet 10/100BaseT)
