System Release 6.0 PCI for Windows

Release Update, Rev 62 — January 30, 2008 151
Dialogic Corporation
1.44.1 Feature Description
Currently, bearer channel time slots on DM3 Boards are numbered from 1 to 15 and 17 to
31 for the QSIG protocol. Channel 16 is reserved for signaling. Thus, the QSIG stack will
reject any calls with the channel identification information element set to 16, as it assumes
that channel 16 is reserved for signaling data.
With the Service Update, you can specify that bearer channel time slots use a
sequentially-ordered logical channel numbering scheme, from 1 to 30, for the QSIG
protocol. This scheme conforms to the ECMA QSIG specification. (See Section 1.44.2,
“Documentation”, on page 152 for reference information on this specification.)
This functionality is available through a new parameter in the CONFIG file and is enabled
on a trunk by trunk basis. You must manually add this parameter in the appropriate
[CCS.x] section of the CONFIG file and turn the feature on. Next, update the
corresponding FCD file by downloading the firmware to the board using the Dialogic
®
Configuration Manager (DCM). Changed values take effect at the time the firmware is
downloaded to the board. For more information about modifying FCD file parameters, see
the Dialogic

Configuration Guide.
The new QSIG parameter is described below.
CCS_ALTQSIGCHANMAP_FLAG (Alternate QSIG Channel Mapping)
Number: 0x26
Description: This parameter enables bearer channel time slots to use a sequentially-
ordered logical channel numbering scheme, from 1 to 30, for the QSIG protocol. If not
enabled, bearer channel time slots are numbered from 1 to 15 and 17 to 31. In this mode,
channel 16 is invalid as it is reserved for signaling.
Note: This parameter only applies to E1 boards.
Values:
• 0 (disabled) (default value)
• 1 (enabled)
Guidelines: To enable the alternate QSIG channel mapping scheme, add this new QSIG
parameter in the [CCS.x] section of a CONFIG file and set to 1.
Example: This example shows the new QSIG parameter added and enabled in the
[CCS.1] section of a CONFIG file:
