System Release 6.1 cPCI for Windows Release Guide — May 2006 36
Support for QSIG NCAS
The ability to make (outbound) and receive (inbound) Non-Call Associated Signaling
(NCAS) calls is supported for the QSIG protocol (E1 or T1) on the Intel NetStructure
®
DMV1200BTEC, DM/V960A-4T1-cPCI and DM/V1200A-4E1-cPCI boards.
Note: The feature is only supported on media loads that use the QSIG T1 or E1
protocol; for example, ml2_qs2_qsige1.
See the Global Call ISDN Technology Guide for more information.
2B channel transfer
2B Channel Transfer (2BCT) is now supported. See the “Network Facility Request -
Two B Channel Transfer” section in the Global Call ISDN Technology Guide.
D-channel backup
In addition to NI-2 ISDN protocol support for D-channel backup, 4ESS and 5ESS
protocol support for D-channel backup has been added in this release. Refer to the
DM3 Configuration Guide for more information.
Dynamic protocol selection
When using DMT160TEC and DMN160TEC boards, this feature enables changes on
a trunk-by-trunk basis within selected front-end configurations (T1 or E1). For
example, if a trunk is configured for E1 at download, a user can change that trunk to a
different variant of the same E1 call control signaling protocol during runtime, for
example, ISDN QSIG to ISDN NET5. Changes from one E1 call control signaling
protocol to another E1 call control signaling protocol, for example, ISDN to R2MF or
vice-versa are not supported. Changes to/from Clear Channel or NFAS are also
excluded. This feature is supported on Intel NetStructure
®
DMT160TEC and
DMN160TEC boards only. See the “Using Dynamic Trunk Configuration” section in
the Global Call ISDN Technology Guide for more information.
Note: The number of channels per trunk must remain the same as originally
configured. This means you cannot dynamically change a span from T1 to E1
or vice-versa. This functionality is only provided at download.
Dynamic line coding and frame selection
Allows dynamic configuration (post download) of the following trunk parameters:
• Line Type (E1 or T1)
• Frame Selection (D4 or ESF when using ISDN on T1; E1 standard or E1 standard
and CRC-4 when using ISDN on E1)
See the “Using Dynamic Trunk Configuration” section in the Global Call ISDN
Technology Guide for more information. This feature is supported on Intel
NetStructure
®
DMT160TEC and DMN160TEC boards only.
Support for Continuity Check IE
Global Call supports the Continuity Check IE (0x53) that is part of Codeset 6 for the
4ESS protocol. See the “Retrieving Continuity Check IE” section in the Global Call
ISDN Technology Guide for more information.
6.5 IP Media API Library
The IP Media library (IPML) is used to control media on IP devices. Voice over IP (VoIP)
applications that use IP signaling stacks other than those supplied with Intel products may
