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

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.

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.
