Cisco IOS Release 12.0(3)T
As mentioned in the previous configuration steps, the E1 R2 signalling type (whether ITU, ITU
variant, or local variant as defined by the cas-custom command) needs to match the appropriate
PCM encoding type as defined by the cptone command. For countries for which a cptone value has
not yet been defined, you can try the following:
• If the country uses a-law E1 R2 signalling, use the GB value for the cptone command.
• If the country uses u-law E1 R2 signalling, use the US value for the cptone command.
For more information about configuring R2 signalling, refer to the Cisco IOS Release 12.0
Dial Solutions Configuration Guide.
4 country name use-defaults Specifies the local country, region, or
corporation specification to use with R2
signalling. Replace the name variable with
one of the supported country names.
Cisco strongly recommends that you
include the use-defaults option, which
engages the default settings for a specific
country. The default setting for all
countries is ITU.
See the cas-custom command in the Cisco
IOS Release 12.0 Dial Solutions Command
Reference for the list of supported regions,
countries, or corporation specifications.

(Optional) Further customizes the R2
signalling parameters. Some switch types
require you to fine tune your R2 settings.
Do not tamper with these commands unless
you fully understand your switch’s
requirements.
For nearly all network scenarios, the
country name use-defaults command
fully configures your country’s local
settings. You should not need to perform
Step 5.

IOS Release 12.0 Dial Solutions Command

signalling command.
