Configure Signaling On Voice Ports - Cisco AS5350 - Universal Access Server Configuration Manual

Chapter 6 Configuring Voice over IP

Configure Signaling on Voice Ports

The Cisco AS5350 and Cisco AS5400 gateways process and manage digital voice calls on the universal
port card. They support voice configuration on channelized T1, E1, and T3 trunk interfaces.
Your universal port card supports ISDN PRI, E1 R2, and T1 CAS digital signaling. Configure your voice
ports according to signaling type. Set parameters as needed for input gain, output attenuation, echo
cancellation, various timeouts, and translation rules. Defaults are generally adequate, but may need to
be tweaked for some networks.
Note For ISDN configurations, voice ports (with serial interfaces acting as D channels) are created
automatically when you configure an ISDN PRI group. Before configuring your voice ports, configure
both B and D channels as described in
Interface."

ISDN PRI Signaling
Signaling for ISDN PRI VoIP is handled by ISDN PRI group configuration. If you have ISDN PRI voice
ports, be sure to complete these tasks:

Ensure that multiframes are established on the serial interfaces (acting as D channel). Then set
parameters as needed for input gain, output attenuation, echo cancellation, various timeouts, and
translation rules.
