– When the number of port and number of licence of Key FD data are insufficient, it causes the FP
operation failure or the IP telephone connection failure.
– After Key FD data is loaded to the Main Site, the service feature, number of port, and number of
licence to be used by each Remote Site are sent to the flash memory of each Remote Site’s MP card
automatically. When Remote Sites operate with survival mode, this data is used.
– Data to be used by each Remote Site is stored in the flash memory every 10 minutes. When a
Remote Site starts operating with survival mode within 10 minutes from starting up, the system
does not operate normally because the data is not stored in flash memory. The system should be
observed for more than 10 minutes after starting up.
– The number of legacy terminal that depends on the number of PIM in TDSW system depends on
the number of port in Remote PIM over IP system. For Key FD data, one PIM licence for TDSW
system is converted to 64 ports for Remote PIM over IP system.
• The number of accommodated terminals/trunks in Main Site and Remote Site should be a maximum
of 1020 ports in the whole system.
[Series 3300 software required]
• The TCP/IP network is required between Main Site and Remote Site. The closed and bandwidth
guaranteed network is preferable, such as IP-VPN (Layer 3 VPN) or wide area Ethernet service (Lay-
er 2 VPN). The following table shows the permissible delay time in the network.
If the network is short of the requirement, it may cause the delay operation of system, the delay and
deterioration of voice packets, disconnection of calls, and frequent changeover to survival mode at
Remote Site.
• The MP card of Remote Site has the same system data as that of Main Site, because Remote Site
automatically gets the data from Main Site when Remote Site starts. In normal operation, Main Site
automatically copies the system data to Remote Site through the network at the time set by CM43
Y=7 once a day.
• This feature is available in the Retrofit System (used as Main Site). The system that using the fol-
lowing MP cards can be mixed used in Remote PIM over IP system in any combination.
Main Site : PN-CP24-A/PN-CP24-B, PN-CP27-A, PN-CP26-A, PN-CP28-A
Remote Site: PN-CP31-A/PN-CP31-B, PN-CP24-A/PN-CP24-B, PN-CP27-A, PN-CP26-A, PN-
CP28-A
NOTE:
PN-CP27-A/PN-CP28-A cannot be used as Backup CPU system in Remote Site.
[Series 3300 software required]
• This feature is not compatible with Fusion service of 2400 IPX.
• The RUN lamp of Remote Sites’ MP card flash at 60 IPM in normal mode and 120 IPM in survival
mode.
