Standards implementation:
IP ToS: Applied to RTP voice packets by default
802.1p/Q: Automatically applied for RSGM and devices in Remote mode
IPSec: Two encryption algorithms (DES/3DES) & two hash algorithms (MD5/SHA-1) are
supported
STUN (Simple Traversal of UDP through NAT): Based on RFC3489, but modified to
efficiently operate for Telenium
IP
communications.
PPPoE: Supported by phones and RSGM
DHCP: Phones support DHCP client configuration in Remote mode
RSGM supports DHCP client for WAN interface, and DHCP server (up to 50
internal clients) on its LAN interface
NAPT: Phones supported behind NAT/NAPT devices
Router in RSGM provides NAT/NAPT support so that all clients can use private
addressing
HTTP: All devices except SHUB8 and POE8 have HTTP-based administration or upgrade
capability
Important Metrics
Parameter Acceptable value
Description
Latency
(delay)
Less than 120
milliseconds
The duration it takes for a packet to move
from one endpoint to another on the network.
Jitter
Less than 20
milliseconds
The variation in latency. When packets arrive
at varying speeds, it can be disruptive to
getting a clear audio stream.
Packet loss
Less than 1%
When some packets do not arrive, there are
gaps in the audio stream. Because voice is a
real-time application, the missed packets will
not be retransmitted.
