1 Introduction
The CG 6565 Installation and Developer's Manual explains how to perform the
following tasks:
• Install and configure a CG 6565 board.
• Verify that the board is installed and operating correctly.
• Use the CG 6565 board keywords to configure the board.
• Use the CG 6565 board utilities.
This manual is for programmers and system integrators who develop media server
applications. This manual defines telephony terms where applicable, but assumes
that the reader is familiar with basic telephony and Internet data communication
concepts, switching, and the C programming language.

Migration information
The CG 6565 board is based on the CG 6000/C, CG 6100C, and CG 6500C boards.
Although the boards are very similar, be aware of the following hardware and
software differences as you migrate from one of these boards to the CG 6565 board.

Overview of the CG 6565 board CG 6565 Installation and Developer's Manual
12 NMS Communications
Software differences
The software differences between the CG 6000/C, CG 6100C, CG 6500C boards and
the CG 6565 board include changes to the following:
• System configuration file
• Board keyword file
• Booting sequence
• Board information
System configuration file
The CG 6565 board product names that appear in the system configuration file
depend on the number of trunks:
Product name Trunks
CG_6565 No trunks
CG_6565_4 4 trunks
CG_6565_8 8 trunks
The following system configuration file excerpt describes a CG 6565 board configured
using no call control:
[CG 6565]
Product = CG_6565
Number = 0
Bus = 2
Slot = 9
File = c6565nocc.cfg
For more information, refer to Creating a system configuration file for oamsys on
page 48.
Board keyword file
The CG 6565 board keyword file differs from the board keyword files of the
CG 6000/C, CG 6100C, or CG 6500C boards in the following ways:
• The CG 6565 board uses framers instead of DSPs for signaling.
You must configure the trunks to perform signaling. Once you configure the
trunks, use only channel associated signaling (CAS) to convey signaling
information:
NetworkInterface.T1E1[x].SignalingType = CAS
The CG 6565 board does not require DSPs to do signaling. Do not set the
following DSP values:
DSP.C5x[0].Files = qtsignal
DSP.C5x[0..1].Files = 8tsignal
• The CG 6565 board merges the core file and the run module to create a file
named cg6565core.ulm. The CG 6565 board does not require the following
DLMFiles[x] settings:
DLMFiles[x] = cg6krun
DLMFiles[x] = cg6500run

CG 6565 Installation and Developer's Manual Overview of the CG 6565 board
NMS Communications 13
• In the CG 6565 configuration file, only set the DLMFiles[x] keyword when
using the board with the following software:
Software Setting
Generic ISDN DLMFiles[x] = c6565igen
Fusion DLMFiles[x] = cg6565fusion
ISDN management DLMFiles[x] = c6565imgt.dlm
DPNSS DLMFiles[x] = c6565.dlm
NaturalFax DLMFiles[x] = cg6565fax.dlm
When you use only one DLM file, xis always 0 (zero). If using more than one
DLM file, number them sequentially starting with 0 (zero). They can appear in
any order. For example:
DLMFiles[0] = cg6565fusion
DLMFiles[1] = c6565igen
• The following keywords are available to set hardware echo cancellation
values:
• HardwareEcho.EchoChipEnabled
• HardwareEcho.Trunk[x].OnOffTimeslots
• HardwareEcho.XLaw
Note: Do not use hardware echo cancellation in conjunction with software
echo cancellation (that is, echo cancellation implemented through programs
running on CG board DSPs).
For more information about hardware echo cancellation, refer to Configuring
hardware echo cancellation on page 31.
• All DSP resources must be managed by the CG 6565C resource management
scheme. Use the following keywords to set up appropriate resource
management:
• Resource[x].Definitions and Resource[x].DSPs instead of
DSP.C5x[x].Files to specify DSPs and DSP functions.
• Resource[x].TCPs instead of TCPFiles[x] to specify TCPs.
The NMS Conferencing service implements resource management differently
than other Natural Access services. For more information, refer to the
NaturalConference Service Developer's Reference Manual.

Booting sequence
The CG 6565 board booting sequence differs from the booting sequence of the
CG 6000/C, CG 6100C, and CG 6500C boards in the following ways:
• CG 6565 boards do not require that you run the burnall script to update the
flash memory on any CG 6565 boards in the chassis.
• CG 6565 boards download the run file, cg6565core.ulm, directly into SDRAM
when the boards boot up using NMS OAM. This file is installed in the
\nms\cg\load directory.
• On CG 6565 boards, the NMS OAM utility, oammon, logs boot-specific
information to cg6x6xboot_bus_slot.txt. For information about using the
oammon utility and generating log files, refer to the NMS OAM System User's
Manual.
The following example shows oammon output:
Fri Feb 11 11:51:01 - OAMEVN_ALERT ERROR Board 1 "Name1"

• CG 6565 boards use C5441 DSPs and not C5420 DSPs for applications. The
DSP files have .f41 extensions instead of .f54 extensions. For example,
CG 6000/C, CG 6100C, and CG 6500C boards use dtmf.f54, but CG 6565
boards use dtmf.f41. The .f41 files are in the \nms\cg\load directory (or
/nms/cg/load for UNIX), which is the same directory that contains .f54 files.
Use f41info to display file resource usage instead of the f54info utility.
• The Fusion msppsamp and tpktsamp demonstration programs include the –E
option to disable software echo cancellation running on the DSPs. Set this
option when using hardware echo cancellation on the CG 6565 board. For
information on using msppsamp, refer to the Fusion Developer’s Manual.
• The CG 6565 daughterboard includes an echo chip for providing hardware
echo cancellation capabilities and to free up DSP resources. For more
information, refer to Configuring hardware echo cancellation on page 31. To
control hardware echo cancellation on a per-timeslot basis, refer to Using
echo cancellation control on page 101.
• Trunk impedance on the CG 6565 board applies to two trunks and must be
identical for trunk pairs. For information about the pairings, refer to
NetworkInterface.T1E1[x].Impedance on page 181.
• CG 6565 boards include a temperature monitoring system. If the board
temperature becomes too high, oammon generates either a warning or a
critical error message. For more information, refer to Temperature monitoring
system on page 25.
• CG 6565 boards do not support the following Switching service functions:
• swiConfigStreamSpeed
• swiGetStreamsBySpeed
All 32 H.100 streams are automatically configured for maximum capacity
(8 Mbit/s or 128 timeslots).

CG 6565 board features
The CG 6565 board is an NMS Communications PCI board. It is a high-density
platform for IVR, fax, VoIP, and media server applications. The board uses a high
performance PowerPC processor.
Configurations with a main board and attached daughterboard provide up to eight T1
or E1 digital trunk interfaces and two Ethernet 10/100/1000Base-T interfaces.
Refer to the NMS Communications web site (www.nmscommunications.com) for a list
of available CG 6565 board configurations, for a list of countries where NMS has
obtained approval for the CG 6565 board, and for product updates.
CG 6565 boards include the following features:
• DSP resources
The CG 6565 board has up to 6384 MIPS of media processing DSPs.
• PCI bus connectivity
Each CG 6565 board is designed to reside in a single PCI bus slot. Each board
contains a universal (5 V or 3.3 V signaling) PCI bus interface compliant with
the PCI Local Bus Specification, Revision 2.2. The PCI interface is a 33 or 66
MHz 32/64-bit device. The PCI-X interface is a 66 or 100-133 MHz 32/64-bit
device and complies with the PCI-X Addendum to the PCI Local Bus
Specification, Revision 1.0.
• Trunk connectivity
Board configurations provide up to eight T1 or E1 network interfaces for
digital trunk connectivity. You must configure the board for either T1 or E1.
For more information, refer to Configuring the T1 or E1 interface on page 30
and to NetworkInterface.T1E1[x].Type on page 192.
• H.100 bus connectivity
The CG 6565 board fully supports the H.100 bus specification. The H.100 bus
enables multiple boards to share data. For example, you can connect two or
more CG 6565 boards for applications that perform trunk-to-trunk switching.
You can use H.100 compatible products from other manufacturers with the
CG 6565 board.
The H.100 interface supports the following stream configurations on the
H.100 bus:
• Full mode: 32 streams at 8 MHz each, which provides 128 timeslots
each for a total of 4096 timeslots.
• Backward compatibility mode: 16 8-MHz streams, 16 2-MHz
streams (total of 2560 timeslots). The H.100 interface can operate
with MVIP-90 boards on the same bus. In this configuration, an
H.100 board in the system must be the bus master.

• Telephony bus switching
Switching for the CG 6565 board offers support for the H.100 bus within the
H.100 architecture. On the CG 6565 board, switch connections are allowed for
a total of 512 full duplex connections between local devices and the H.100
bus.
• Ethernet connectivity
The CG 6565 board contains two 10/100/1000Base-T Ethernet connections
for fast Ethernet connectivity and support of both IPv4 and IPv6. For more
information, refer to Connecting to an Ethernet network on page 45.
• Echo cancellation
CG 6565 boards support up to 480 ports of line echo cancellation with 64 ms
tails.

Software components
Natural Access is a development environment that provides such services as call
control, system configuration, and voice store and forward. CG 6565 boards require
the following software components that are available with Natural Access:
• NMS OAM (Operations, Administration, and Maintenance) software and
related utilities.
• Configuration files that describe how the board is set up and initialized.
• Runtime software and drivers that control the CG 6565 board.
• One or more trunk control programs (TCPs) that enable applications to
communicate with the telephone network using the signaling schemes
(protocols) on the trunk.
NMS OAM
NMS OAM manages and maintains the telephony resources in a system. These
resources include hardware components (including CG boards) and low-level board
management software modules (such as clock management).
Using NMS OAM, you can:
• Create, delete, and query the configuration of a component.
• Start (boot), stop (shut down), and test a component.
• Receive notifications from components.
NMS OAM maintains a database containing records of configuration information for
each component as shown in the following illustration. This information consists of
parameters and values.
