Comparison of IPN-2 and IPN-3 Cards

The following table provides the similarities and differences between the IPN Series 2 and the IPN Series 3 cards. Host developers must take the differences into account to integrate the IPN Series 3 card into a CSP

Table 4-1 IPN-2 and IPN-3 Cards

Information | IPN-2 Card | IPN-3 Card
--- | --- | ---
CPU | PPC8260 | PPC8270
Memory | 128 MBs | 256 MBs
Board ID | 101 (0x65) | 145 (0x91)

Network Interface | All ports support 10/100 Mbps full/half duplex. Dip 4 control auto-negotiation or force full 100 Mbps Three Ethernet Ports configured as a single Link Aggregation Group. All ports connected to an unsecured public data network | All ports support 10/100 Mbps full/half duplex. Dip 4 control auto-negotiation or force full 100 Mbps In the current release two ports are used: DATA 0 DATA 1 Future releases will include the following: - Four Ethernet Ports connected to an unsecured public data network: - Two Ethernet Ports connected the secured, Control network. - Redundant port links In the current release, the control ports and link redundancy on the data ports are disabled. For backward compatibility the IP Address Assign API message binds the motherboard IP address to the data network - not the control network.
Binding Logical Spans/Channels | Logical spans/channels are bound to the IPN-2 card | Logical spans are bound to a module.

Asymetrical Codecs | Yes | No
VoIP Module Profiles | Profile #1: G.711 Only (512 channels) Profile #2: LBR+T.38 (256 channels) | Profile #4: G.711 Only (512 channels) Payload sizes 20ms and 30ms only. No RTP Redundancy. Profile #5: LBR+T.38 (256 channels)
VoIP Endpoint Terminal Capabilities | 64 ms Echo Tail, 300ms Jitter Buffer | 128 ms Echo Tail, 200ms Jitter Buffer
EXS API Interface and Usage | See IPN-3. | All messages used to interface with the IPN-2 card are used the same way with the IPN-3. All are identical except the following: Card/Module Status Report/Query (0xA6/0x83): The unused third module data is removed. Resource Attribute Configure/Query (0xE3/0xE4): Slight differences in the terminal capabilities.
Default Resource Profile | LBR - G.711 + G.726 + G.723.1 + G.729A/B + T.38 (Profile #2) - 256 channel/modules | LBR - G.711 + G.726 + G.723.1 + G.729A/B + T.38 Profile #5) -256 channels/modules
Port Consumption Mode | Configure as either a port consuming or non-port consuming device. Granularity on line card level - not span level. In non-port consumption mode, can apply 3, 0, -2, -3, -4, -6, -9 dB of attenuation on both channels. Default is non-port consuming | Configure as either a port consuming or non-port consuming device. Granularity is on line card level - not span level. Can have four fixed pads: 3, 0, -3, -6 dB Default is non-port consuming
Resource Licensing | Each channel is logical span takes up one resource point. Unlicensed IPN-2 provides 96 resource points per module. | Each channel is logical span takes up one resource point. Unlicensed IPN-3 provides 96 resource points per module.
System Software Supported | 8.1 | 8.4.1

A computer, attached to the Excel platform through an RS-232 or Ethernet link, from which you run the telecommunications application that controls the Excel platform.
Voice over Internet Protocol. The delivery of voice information in digital form in discrete packets rather than in the traditional circuit-committed protocols of the public-switched telephone network (PSTN).
See Pulse Code Modulation.
The protocol used in most local area PC networks. Typically, most Ethernet networks support data transmission speeds up to 10 Mbps, but 100 Mbps is also possible.
Internet Protocol. Part of the TCP/IP family of protocols used to route messages and tracks the addresses of nodes.
See Programmable Protocol Language.
Real-Time Transport Protocol. Supports transport of real-time data like interactive voice and video over packet-switched networks.
An H.323 terminal or gateway, or MCU. An endpoint can call and be called. It generates and/or terminates the information stream.
The point in the Excel platform where a DS0 connects to a network. Also known as a "socket."
