June 2005 RLC description
Operational characteristics
The RLC provides a number of unique features that distinguish it from other
remote service products.
These features include:
„
adjustable quality of service (QoS) using QoS Transitioning Technology
„
port sharing options
„
multiple security levels
„
packet voice processing
„
dial-up trunking
„
bandwidth allocation
„
Meridian telephone equipment compatibility
Adjustable QoS using QoS Transitioning Technology
Nortel’s patented QoS Transitioning Technology monitors the QoS level on the
internet protocol (IP) portions of your Remote Gateway 9100 Series system.
This feature detects poor voice QoS when it occurs. The QoS level is a user-
oriented metric that takes one of ten settings. Using Configuration Manager, you
can select an acceptable transition threshold from among the ten predefined
settings to identify the limits of acceptable voice QoS.
Configuring QoS Transitioning Technology to provide satisfactory results
requires a detailed understanding of traffic on your IP network. For guidance on
evaluating and adjusting your network’s QoS, refer to the
Remote Gateway 9100
Series Network Engineering Guidelines (NTP 555-8421-103). Refer to page 16
for instructions on obtaining this document.
QoS on shared networks
High volumes of data packets can cause QoS problems for voice traffic on
shared networks. Configuring the router to send voice packets ahead of data
packets (prioritizing voice packets) can address some QoS concerns. For further
details, refer to “Prioritizing voice traffic over shared networks” on page 185.
