Trunk Group Types

The Cisco BTS 10200 Softswitch supports the following trunk group types: announcement, channel
associated signaling (CAS), Integrated Services Digital Network (ISDN), Signal System 7 (SS7), and
SOFTSW (Session Initiation Protocol (SIP)). The Trunk Group table defines common information based
on the trunk group type. The Cisco BTS 10200 Softswitch supports announcement, CAS, ISDN, SS7 and
SOFTSW trunk group profiles. The following trunk group types are discussed:
•

Announcement

The Announcement Trunk (annc-trunk) table is used when an announcement server is required in an
Asynchronous Transfer Mode (ATM) network.

Channel Associated Signaling

The CAS Trunk Group Profile (cas-tg-profile) table holds common information on a CAS trunk group.
It supports the following signaling types: dual tone multifrequency (DTMF) loop start, DTMF ground
start, multifrequency (MF) im start, MF wink start, DTMF im start, DTMF wink start. A cas-tg-profile
record can be shared by multiple CAS trunk groups.

Integrated Services Digital Network

The ISDN Trunk Group Profile (isdn-tg-profile) table holds common information regarding an ISDN
trunk group. This table is used to configure the Cisco BTS 10200 Softswitch to interact with various
types of private branch exchanges (PBXs) having different configurations (such as non-facility
associated signaling (NFAS), facility associated signaling (FAS), and so forth), initialization procedures
(service or restart), or supporting different call control or maintenance timer values. The isdn-tg-profile
record can be shared by multiple ISDN trunk groups. The table tokens configure the Call Agent to
communicate with a particular PBX.

Signaling System 7

The SS7 American National Standards Institute (ANSI) Trunk Group Profile (ss7-ansi-tg-profile) table
holds common information regarding an SS7 trunk group such as continuity test (COT). This table can
be shared by multiple SS7 trunk groups.
