DESCRIPTION
DHCP (Dynamic Host Configuration Protocol) allows the individual
clients (computers) to obtain the TCP/IP configuration at start-up from
a centralized DHCP server. Your device has built-in DHCP server
capability enabled by default. It can assign IP addresses, an IP default
gateway and DNS servers to DHCP clients. Your device can also act
as a surrogate DHCP server (DHCP Relay) where it relays IP address
assignment from the actual real DHCP server to the clients.
IP alias allows you to partition a physical network into logical networks
over the same Ethernet interface. Your device supports three logical
LAN interfaces via its single physical Ethernet interface with the your
device itself as the gateway for each LAN network.
You can configure multiple voice (SIP) accounts.
Your device is a SIP Application Layer Gateway (ALG). It allows VoIP
calls to pass through NAT for devices behind it (such as a SIP-based
VoIP software application on a computer).
The built-in adaptive buffer helps to smooth out the variations in delay
(jitter) for voice traffic (up to 60 ms). This helps ensure good voice
quality for your conversations.
Voice Activity Detection (VAD) reduces the bandwidth that a call uses
by not transmitting when you are not speaking.
Your device generates background noise to fill moments of silence
when the other device in a call stops transmitting because the other
party is not speaking (as total silence could easily be mistaken for a
lost connection).
You device supports G.168 of at least 24 ms.
This an ITU-T standard for eliminating the echo caused by the sound
of your voice reverberating in the telephone receiver while you talk.
Get the current time and date from an external server when you turn
on your WiMAX Modem. You can also set the time manually.
Use the WiMAX Modem's logging feature to view connection history,
surveillance logs, and error messages.
Enhanced Variable Rate Codec (EVRC), G.711 (PCM
law), G.729a, and G.723.1
T.38 FAX relay (FAX over UDP).
G.711 fax relay for fax calls and be able to renegotiate codec to G.711
if a fax call is detected.
Supports different distinctive ring tones on each line.
Prioritize VoIP traffic originating from the RJ-11 ports over any other
traffic.
