System Release 6.0 PCI for Windows

Release Update, Rev 62 — January 30, 2008 351
Dialogic Corporation
To disable the Active Talker algorithm, set the parameter 0x3b03 to a value larger than the
maximum number of conferences per DSP; setting it to Conf_MaxTotalParties, or per board total
number of parties, will suffice, to a maximum of 255.
Even without Active Talker, scaling is also enabled by default. If not required, set the parameter
0x3b04 to a number larger than the maximum number of parties per DSP, and again using
Conf_MaxTotalParties will suffice, to a maximum of 255.
Update to Section 6.9, [lineAdmin.x] Parameters (Digital Voice)
In the guidelines for the SignalingType parameter, the note about NFAS D channel
backup (DCBU) supported only on ISDN NI-2 protocol is incorrect. DCBU is
supported on 4ESS, 5ESS, and NI-2.
Update to Section 6.9, [lineAdmin.x] Parameters (Digital Voice)
Because of a feature in the Service Update, a new parameter, 0x1626, can be
manually added to the CONFIG file for trunk preconditioning. This parameter should
be documented in Section 6.9, [lineAdmin.x] Parameters (Digital Voice). For
information about this feature and the new parameter, see Section 1.73, “Trunk
Preconditioning”, on page 256 of this Release Update.
Update to Section 6.9, [lineAdmin.x] Parameters (Digital Voice)
The following new parameter is added in Section 6.9, [lineAdmin.x] Parameters
(Digital Voice):
InitialBitPattern (Initial CAS Signaling Bit Pattern)
Number: 0x1625
Description: The InitialBitPattern parameter defines the values of the CAS ABCD signaling
bits that are transmitted for all channels on the specified line at the time the firmware is
downloaded and initialized.
Values: 0x0 to 0xf, where the hexadecimal value represents the binary ABCD bit values. For
example, 0xd defines the ABCD bit pattern as 1101.
Guidelines: For a T1 line, the default is 0x0. For an E1 line, the default is 0xd.
Update for CRC Checking Parameter (PTR# 31812/32282)
The following information about the CRC Checking Parameter should be included in
the Configuration Guide:
A T1 front end can run two different framing algorithms when configured as extended
superframe (ESF): a default algorithm and an alternate CRC-6 checking algorithm.
The CRC-6 checking algorithm allows the circuit to confirm the CRC-6 bits in the
