Preparing Information to Configure Digital Voice Ports
Gather the following information about the telephony network connection that the voice port will be
making:
Line interface: T1 or E1
Signaling interface: FXO, FXS, or E&M. If the interfaces are Primary Rate Interface (PRI) or BRI,
see the “Configuring ISDN Interfaces for Voice” chapter in this configuration guide and Cisco IOS
Terminal Services Configuration Guide.
Line coding: AMI or B8ZS for T1, and AMI or HDB3 for E1
Framing format: SF (D4) or ESF for T1, and CRC4 or no-CRC4 for E1
Number of channels
Table 8 describes voice-port hardware configurations for various platforms. After the controllers have
been configured, the show voice port summary command can also be used to determine available voice
port numbers. If the show voice port command and a specific port number is entered, the default
voice-port configuration for that port displays.
