Service Conditions

1.Up to 956 IP terminals can be accommodated per system.

2.Total number of ports for IP terminals, legacy stations/trunks (except for AP cards) and IP PADs is up to 1020 per system. See chapter 1 for capacities of stand alone and network configurations.

Note: Legacy stations/trunks means the ones connected to the Time Division Switch (TDSW). Examples of legacy station/trunk cards are LC, DLC, COT, PRT, CCT, DTI, 8RST (DTMF receivers), CFTB (Conference trunk), etc.

3.IP terminals are accommodated in the Virtual PIM’s (Virtual FPs) so that the hardware-PIM’s are not required to accommodate IP Enabled Dterm terminals. The Virtual PIM is software-defined PIM used for data assignment for IP Enabled Dterm terminals and Virtual IP trunks (for CCIS Networking via IP). Maximum nine (15) Virtual PIM’s are provided per system. Total number of the Virtual PIM’s (for IP terminals) and hardware-PIM’s is up to 16 per system.

4.Minimum one hardware-PIM is required per system to accommodate the MP card. The number of hardware- PIM’s depends on the number of legacy stations/trunks and IP-PADs. Up to two hardware-PIM’s (128 LT ports) can be controlled by the MP without the addition of an FP card. With three FP cards, up to eight hardware-PIM’s (512 LT ports) can be controlled [One FP card controls up to two hardware- PIM’s (128 LT ports)].

5.The IP-PAD is required for connections between IP terminals and legacy stations/trunks. The IP- PAD converts voice packet data to PCM signals. The number of IP-PADs depends on the traffic volume of those connections. Up to eight IP-PADs can be accommodated per system, thus providing 256 channels. Up to two IP-PADs can be controlled by the MP without FP cards, and additional IP-PADs can be controlled by the FP cards (two IP-PADs per FP card).
