Link utilization assessment

ITG Line 2.0/i2004 Internet Telephone Description, Installation, and Operation
• p2 - The preferred strategy for the choice of codec for intrazone calls
(that is, preserve voice quality or preserve bandwidth)
• p3 - The total bandwidth available for interzone calls
• p4 - The preferred strategy for the choice of the codec for interzone calls
If no IP voice zones are configured, zone 0 operates as a default zone with no
restrictions on bandwidth usage. However, if any zones are configured, zone
0 must also be configured if it is referenced by any i2004 Internet Telephones
or ITG Line 2.0 TNs.
When moving an i2004 Internet telephone, the Meridian 1
Administrator must change the zone assignment in Overlay 11.
See "X11 Input/output Guide", NTP 553-3001-511.
Procedure 4
Link utilization assessment procedure
1 Obtain a current topology map and link utilization report of the intranet.
2 Visually inspect the topology map to reveal which WAN links are likely
to be used to deliver ITG traffic. Alternately use the traceroute tool (see
"Measuring tools" on page 70).
3 Find out the current utilization of the WAN links. For example, the link
utilization may be averaged over a week, a day, or an hour.
4 Obtain the busy period (peak hour) utilization of the link.
5 Also, because WAN links are full-duplex and data services exhibit
asymmetric traffic behavior, obtain the utilization of the link
representing traffic flowing in the heavier direction.
