Note 1: The KX-NCP500 Physical Shelf has a total of 5 Free Slots, 3 of which are small and 2 of which are large. The small slots can accept 4-Circuit Loop Start Analog Trunk Cards (LCOT4), 23B+D Channel ISDN Primary Rate Interface Cards (PRI23) or 4-Port Digital Hybrid Extension Line Cards (DHLC4). The large slots can accept 24-Channel T1 Cards (T1), 8-Port Digital Extension Line Cards (DLC8), 16-Port Digital Extension Line Cards (DLC16), 8-Port Single Line Extension Cards (SLC8), 16-Port Single Line Extension Cards (SLC16) or a 3-Module Option Board for Door Controllers, DISA/OGM, Sensors or an Echo Canceling card. Each time you populate a slot with a physical card, you are effecting the ratio of Trunks -to- Extensions. Example: A configuration using all physical slots for 64 trunks means that there is no room for physical extensions or special option cards such as Door Controllers, UCD/DISA, etc. Likewise, a configuration using all physical slots for 44 extensions means that there is no room for Trunks or special option cards.
Note 2: The KX-NCP500 Virtual Shelf has a total of 8 Slots - 4 are Trunk related and 4 are Extension related. Each virtual trunk slot can accommodate 16 trunks for a total of 64 Virtual Trunks. Slots accept either SIP CO Lines or H.323 CO Lines provided that no more than 32 of these are H.323. Each virtual extension slots can accommodate up to 32 IP extensions. IP extensions are available as SIP (hard or soft) or Panasonic Proprietary (also hard or soft).
Note 3: Totals are somewhat dynamic. Even though the maximum number of trunks is 128 and the maximum number of extensions is 172, you cannot realize both at the same time since you would run out of slots. Your Panasonic Certified Dealer will help you balance these maximums so as to optimize the system for future growth.
