Digital Articulation Anchorage Parameters
After ambience up the controller, you can configure articulation anchorage ambit for that digital
voice port. Back you defined a ds0-group, the arrangement automatically created a logical
voice port. You charge again access the voice-port agreement approach to configure portspecific
parameters. Each articulation anchorage you set up in agenda articulation anchorage agreement is one
of the analytic articulation ports you created with the ds0-group command.
Follow these accomplish to configure basal ambit for agenda T1/E1 articulation ports:
Step 1. Access voice-port agreement mode.
Router(config)#voice-port slot/port:ds0-group-number
Step 2. Select a two-letter keyword for the articulation alarm advance tones and added localespecific
parameters to be acclimated on this articulation port.
Router(config-voiceport)#cptone locale
Step 3. Specify the companding accepted that is acclimated to catechumen amid analog and
digital signals.
Router(config-voiceport)#compand-type {u-law | a-law}

Note This command is acclimated in cases back a DSP is not used, such as bounded crossconnects,
and overwrites the compand-type amount set by the cptone command.
Step 4. Activate the articulation port.
Router(config-voiceport)#no shutdown
Figure 4-14 and Example 4-4 allegorize a complete agenda articulation anchorage agreement that
specifies US as the blazon of alarm advance tones to use and u-law as the companding type.
