IPTX v Summary Configurable parameters on FXS ports include signal, cptone, description, ring frequency, ring cadence, disconnect-ack, busyout, station id name, and station id number. Configurable parameters on FXO ports include signal, ring number, dial-type, description, and supervisory disconnect. Configurable parameters on E&M ports include signal, operation, type, auto-cut-through, and description. Configurable timer and timing parameters define initial digit and interdigit timing, digit and interdigit duration, as well as ringing time. Digital voice ports are created with the ds0-group command in the T1/E1 controller.

© 2005 Cisco Systems, Inc. All rights reserved. IPTX v Summary (Cont.) ISDN can be implemented in two different ways: BRI and PRI. In most countries, customer access to BRI is available at the S/T interface. Enabling ISDN BRI requires global configuration and interface configuration commands. Some ISDN switches require the configuration of SPID numbers. A T1 controller configuration must include the framing type and line coding. ISDN PRI configuration requires that the pri-group command specify the time slots that are used for voice and signaling. ISDN PRI does not require SPIDs. The ISDN PRI D channel and B channel are configured separately from the controller using the interface serial command. ISDN PRI requires that a T1 (or E1) controller be configured.
