System Release 6.1 cPCI for Windows Release Guide — May 2006 17
E1/T1 CAS/R2 Technology Guide. DMN160TEC boards do not support CAS/R2
protocols.
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.
D channel backup support for 5ESS and 4ESS
In addition to the NI-2 ISDN protocol, the CONFIG File parameter
NFAS_Standby_IntlD (Standby Instance Identifier) now supports D channel backup
(DCBU) on the 4ESS and 5ESS protocols. Refer to the DM3 Configuration Guide for
more information.
Support for 2B Channel Transfer (2BCT)
Allows the connection of two independent B Channel calls at an ISDN PRI user's
interface to each other at the PBX or CO. The ISDN PRI user sends a Facility
message to the PBX or CO requesting that the two B Channel calls be connected. If
accepted, the user is released from the calls. See the Global Call ISDN Technology
Guide for details.
Dynamic line coding and frame selection
Provides new parameter values for gc_SetConfigData( ), allowing dynamic
configuration of the following trunk parameters at runtime:
• Line Type (E1 or T1)
• Frame Selection (D4 or ESF when using T1; E1 standard or E1 standard and
CRC-4 when using E1)
Refer to the Global Call ISDN Technology Guide and the Global Call E1/T1 CAS/R2
Technology Guide.
PDK Trace support on the DMT160TEC board.
The PDK Trace tool allows those who use a DM3 PDK protocol to log specific
information related to the operation of the protocol. Refer to the Diagnostics Guide for
more information.
Improved Configuration Manager
Provides a trunk configuration utility for DMN160TEC and DMT160TEC boards. Refer
to the DM3 Configuration Guide for more information.
