Applications Low-Bit Rate Voice Server
High reliability in mission-critical installations
LBRV is suited to carrier networks and service organizations where down-time is
unacceptable. Examples include call centers, help desks, and inter-exchange trunks. LBRV
offers high reliability through:
•
Hardware redundancy
•
Environmental ruggedness
•
No moving parts
•
Path redundancy (with FRS). It can be achieved through Backup PVC feature which
switches to an alternate path upon either Loss of LMI (loss of FR administration
connection) or WAN CGA alarm (T1/E1 failure)
Carrier networks requiring specialized Telco interfaces
This integrated access system has specialized telco interfaces found in carrier environments
such as:
•
Coin phone (12/16 kHz or battery reversal)
•
64 kbps G.703 co- / contra-directional
•
BRI & PRI ISDN voice
•
T1 and E1 interface
This integrated access system is equipped with the LBRV Server card which offers
cost-effective applications including:
•
Bulk voice compression for remote call center
•
Back-hauling voice for new carriers (e.g. centralized voice mail)
•
Extending voice access network over VSAT
