Gateway Feature Summary 
Feature
Description
Interoperability
The gateway provides a high degree of interoperability with other H.323 
compliant gateways, gatekeepers, terminals, proxy, and Multipoint Control Unit 
(MCU) products by being based on the H.320 standard and H.323 protocol stack.
Web-based management
The gateway features the gateway interface. This is a web interface used to 
configure and monitor the gateway. You can view and modify all aspects of the 
gateway configuration from a remote location using a Java-enabled web browser.
SNMP management
The gateway features Simple Network Management Protocol (SNMP) 
management that supports all aspects of monitoring, diagnostics, configuration, 
and trapping.
Diagnostics
The gateway features front and rear panel LED indicators that display status for 
the unit. You can also access remote diagnostics of the unit through the gateway 
interface, Telnet, SNMP, or a serial port.
Network load balancing
The gateway supports load balancing on the network by communicating with a 
gatekeeper through H.323 RAI (Resource Available Indication)/RAC (Resource 
Available Confirmation) messages.
T.120 data collaboration
The gateway supports data transfers in calls between ISDN and IP by using high 
speed T.120 in HMLP and VarMLP formats.
Quality of service (QoS)
The gateway features configurable coding of media packets to achieve QoS 
routing priority on the Internet Protocol (IP) network. The Type of Service (ToS) 
bits of the IP datagram header can be configured for priority level.
Dial plan
The gateway supports a simplified dial plan for outbound dialing using a single 
universal prefix. Using the dial plan, the gateway automatically detects the 
capabilities received in the Setup message from the IP endpoint and sets the same 
bit rate for the ISDN (or serial interface) side of the call.
Direct dialing and call routing
The gateway dial plan supports these direct dialing and call routing facilities:
  •
Direct Inward Dialing (DID)
  –
Multiple Subscriber Network (MSN)
  –
Q.931 Sub-addressing Information Element
Internal and External Interactive Voice Response (IVR)
  •
TCS4
  •
Default extension
Access control
The gateway features password-controlled access to the gateway interface. You 
can define up to ten different administrator access profiles for the gateway.
DTMF translation
The gateway supports translation between in-band Dual Tone Multi-Frequency 
(DTMF) signals (on the ISDN side) and out-of-band H.245 messages (on the IP 
side). DTMF translation occurs for voice and video calls.
