Connecting to the Device
An BSGX4e unit provides two telephony interfaces: one FXS port for connectivity
of analog phones or fax machines and one FXO port to act as a backup lifeline to
the PSTN.
Security

Intrusion Detection System (IDS), Application Layer Gateway (ALG), and support
for network address translation (NAT) and virtual private networks (VPNs).
Multi-Service QoS
The BSGX4e unit includes an advanced QoS mechanism called Guarantee of
Service (GoS). This easy-to-configure mechanism ensures the optimal priority and
bandwidth allocation for multiple classes of critical traffic. It is compatible with
DiffServ with support for Terms of Service (ToS) field remarking.
LAN Switch
An BSGX4e unit includes a 4-port switch, with support for Layer 2 QoS and VLAN
segmenting.
Monitoring
An BSGX4e unit dynamically monitors and provides statistics for both data and
voice flows (such as Mean Opinion Score (MOS) scores gathered per call).
Management
Perform configuration and monitoring by entering commands or by selecting
options from a Web browser interface. The management system assures secure
remote access with SSH and Hypertext Transfer Protocol over Secure Socket Layer
(HTTPS).
