# CG 6565E board features

The CG 6565E board is a PCI Express media 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 www.dialogic.com/declarations/default.htm for a list of available CG 6565E board configurations, for a list of countries where Dialogic has obtained approval for the CG 6565E board, and for product updates.

CG 6565E boards include the following features:

- DSP resources

  The CG 6565E board has up to 6384 MIPS of media processing DSPs.

- x4 PCIe connectivity

  Each CG 6565E board is designed to reside in a single PCIe slot. Each board contains a x4 PCIe interface compliant with the PCI Express Base Specification, 1.1.

- 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 and to NetworkInterface.T1E1[x].Type.

- H.100 bus connectivity

  The CG 6565E 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 6565E boards for applications that perform trunk-to-trunk switching. You can use H.100 compatible products from other manufacturers with the CG 6565E 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 4096 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 6565E board offers support for the H.100 bus within the H.100 architecture. On the CG 6565E 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 6565E 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.

- Echo cancellation

  CG 6565E boards support up to 480 ports of line echo cancellation with 64 ms tails.
