Bearer Independent Call Control (BICC) Over ATM/IP Switching Systems Generic Requirements
Document Number GR-3100
Issue Number 03
Issue Date Dec 2001
ABSTRACT: Issue 3 of GR-3100, Bearer Independent Call Control (BICC) over ATM/IP Switching Systems Generic Requirements, replaces Issue 2.
GR-3100 provides the Telcordia view of proposed generic requirements for the use of the Bearer Independent Call Control (BICC)
protocol for signaling between Serving Nodes (SNs) to establish and release a call over an ATM or IP backbone network in which the call
control signaling and bearer control signaling are separated. Between SNs, the control of ATM bearers is provided by the ATM Forum User
Network Interface specification, Version 4.0 (UNI 4.0) and Private Network-Network Interface, Version 1.0 (PNNI 1.0) signaling
protocols. The IP bearer connection associated with the call is set up using the BICC IP Bearer Control Protocol, draft ANSI T1.ipbcp
which is tunneled in the BICC call control messages between the SNs using the BICC Bearer Control Tunneling Protocol, draft ANSI
T1.bctp. BICC is an adaptation of the narrowband ISDN User Part (ISUP) for the support of narrowband ISDN services independent of the
bearer technology and signaling message transport technology used.
This document represents current views based, in part, on existing and evolving industry standards related to BICC. This document,
wherever possible, points to specific requirements already listed in other Telcordia generic requirements documents or to industry
This document provides requirements for the following two types of SNs: Interface Serving Node (ISN) and Gateway Serving Node (GSN).
For the support of BICC at the end office, the ISN [Originating SN (O-SN) and Destination SN (D-SN)] provides an interface to the
access networks and supports interworking with various legacy access protocols (e.g., DTMF, ISDN). For the support of BICC at the
tandem level, the ISN [Originating ISN (O-ISN) and Destination ISN (D-ISN)] also provides an interface to the circuit-switched networks
(e.g., PSTN, ISDN) using ISUP. The GSN provides inter network gateway functionality, for call and bearer, using the BICC protocol.
This document includes procedures to support calls between client company networks and other Interconnecting Networks (ICNs). These
ICNs include Interexchange Carriers (IXCs); International Carriers (INCs); and other Local Exchange Carriers (LECs), including
Competitive Local Exchange Carriers (CLECs). This document provides requirements for the BICC signaling protocol independent of the
network used for its transport. In addition, this document provides high-level bearer control signaling requirements for ATM/IP bearer
setup and release.
Issue 3 of GR-3100-CORE reflects additions to Section 2 in support of BICC at end office, and revisions to Section 3 in support of
protocol alternatives for transporting BICC messages between BICC network elements. Additionally, Issue 3 includes additions to
Section 5 to include IP bearer setup call flows, additions of new requirements in Section 5 in support of BICC at end office, and new
requirements in Section 5 in support of calls over IP bearer. Issue 3 also includes additions to Section 6 in support of operation of
the BICC protocol with IP Bearer Control Protocol, and additions in support of establishment and release of IP bearer connections.
Additions to Section 9 in support of BICC evolution, BICC capability sets (e.g., CS 1, CS 2), and industry status (ITU-T and T1S1) are
also included, as well as additions and changes in Appendixes A, B, and C reflecting support of IP bearer, and alignment with ANSI BICC
CS 1+ specifications.
