Setting WAN Bandwidth Limits Between Network Regions
Administrator’s Guide for Avaya Communication Manager

November 2003
The bandwidth usage numbers shown above assume 6 bytes for Multilink Point-to-Point Protocol (MP)
or Frame Relay Forum (FRF), 12 Layer 2 (L2) header, and 1 byte for the end-of-frame flag on MP and
Frame Relay frames for a total of 7 byte headers only. They do not account for silence suppression or
header compression techniques, which might reduce the actual bandwidth. For other types of networks
(such as Ethernet or ATM) or for cases where there is a lot of silence suppression or header compression
being used, the network may be better modeled by administering the CAC-BL limits in terms of number
of connections rather than bandwidth used.
Instructions
NOTE:
All DIRECT links must be administered first, and INDIRECT links administered last.
To set bandwidth limitations between directly-connected network regions:
1
Type change ip-network region <n>,
where n is the region number you want to administer, and
press
ENTER
.
2
The
IP Network Region
screen appears.
3
Scroll to page 3 of the form, Inter Network Region Connection Management.
4
In the
codec-set
field, enter the number (1-7) of the codec set to be used between the two regions.
5
In the
Direct WAN
field, enter y.
6
In the
WAN-BW-limits
field, enter the number and unit of measure (Calls, Kbits, Mbits, No Limit)
that you want to use for bandwidth limitation.
7

5
In the
Intervening-regions
fields, enter up to four intervening region numbers between the two
indirectly connected regions.

NOTE:
Type display ip-network region <n> to view the current settings of inter-network region
connections. Type status ip-network region <n> to view the current status (i.e.,
bandwidth and number of connections being used) of network-region connections.
