IP Office 500 Control Unit

With a greater VCM channel capacity and performance, the IP Office 500 (IP500) is the most suitable of the IP Office range for IP Telephony applications. It also provides an entry level offer into the IP Office family through IP Office Standard Edition software. The IP500 also differs from the IP412 by providing a greater trunk expansion capability of up to eight four PRI interfaces (maximum 192/240 trunks). The IP500 is a stackable unit with an optional 19" rack mounting kit and an optional wall mounting kit for smaller configurations. The IP500 includes:

  • 4 slots to house a mixture of extension cards and VCM cards
  • Digital Station 8 card
  • Phone 2 and Phone 8 cards
  • VCM-32 and VCM-64 cards
  • Optional trunk daughter card support:
  • Analog Trunk Module 4 card
  • BRI-4 and BRI-8 cards (2 x 2B+D and 4 x 2B+D channels respectively)
  • Single and Dual Universal PRI cards
  • Support for IP400 trunk and VCM cards using a Legacy Card Carrier
  • Slot for smart card Feature Key – required for system operation as well as licensing of optional features.
  • 9-pin DTE Port for maintenance.
  • Support for up to 8 IP500 Expansion Modules (requires upgrade to Professional Edition):
  • Phone modules (8, 16, 30)
  • Digital Station modules (16, 30)
  • Analog Trunk Module 16
  • BRI So8 module
  • IP400 expansion modules (not WAN3 10/100 or Network Alchemy modules)
  • External O/P socket supporting two relay on/off switch ports, e.g. for door entry systems.
  • Audio input port for external music on hold source.
  • 48 Data channels
  • Up to 30 VoiceMail Pro ports
  • Two 10/100 switched Ethernet ports (Layer 3).

IP500 Voice Networking License

QSIG, H.323 and SCN capabilities are not enabled by default in the IP500. An additional license is required to enable this functionality with 4 simultaneous networking channels (no channel limit for QSIG). Additional channels can then be licensed in increments of 4. A Voice Networking license is still required to enable QSIG, even though there is no limit to the number of QSIG calls that can be made or received once licensed.

IP Office Standard Edition

By default the IP500 control unit runs a subset of full IP Office functionality called IP Office Standard Edition. In this mode the IP500 is restricted to a maximum of 32 users in the base control unit with no expansion. Supported options include Embedded Voicemail, Phone Manager Lite/Pro/PC Softphone, SoftConsole, TAPI, SMDR, SIP trunking, mobile twinning, VPN Phone and IP DECT, as well as licenses for voice networking (H.323 or SCN). IP Office Standard Edition does not support advanced applications (VoiceMail Pro, CCC, Conference Center, etc). This restriction can be removed by adding an IP Office Professional Edition Upgrade license to the configuration.

IP Office Professional Edition

By purchasing the upgrade license from Standard Edition to Professional Edition, additional functionality is enabled. This includes the ability to expand the system using up to eight external Expansion Modules, allowing the IP500 to support a maximum of 272 extensions through a mixture of analog, digital or IP handsets. If additional analog trunks are required, these can be aggregated in groups of 16 on each analog expansion module. Note that the Professional Edition also enables the licensing of advanced applications such as VoiceMail Pro.

The following table shows which features are supported by Standard Edition and which require the upgrade to Professional Edition.

Call Capacity

Busy Hour Call Complete (BHCC) is a measure used to test IP Office systems under a high call load. For BHCC tests, each incoming call rings for 5 seconds, is answered and stays connected for 6 seconds. The BHCC figures for the different IP Office control units are listed below. Note that in some cases the BHCC figure achievable will be limited by the number of incoming trunks supported.

  • IP500 = 36000.

Telephone Extension Cable Lengths

The following table details the maximum cable lengths supported for the telephone ranges. These figures assume that standard twisted-pair telephone cable or CAT5 network cable is used.

Heat Dissipation

Note that the above numbers are for reference only. For practical purposes, for example the calculation of heat dissipation, it is recommended to base environmental requirements (for example air cooling or UPS ratings) on the maximum input rating of the power supplies of the planned IP Office configuration, as follows.

In order to calculate the maximum, that is worst case, amount of heat that can be generated by an IP Office system, it is assumed that all input power is converted to heat; whether from the PSU itself, the system unit, expansion module and/or cabling.

Heat dissipation is normally measured in British Thermal Units (BTU's). A heat value expressed in Watts can be converted to BTU/hr by multiplying by 3.41297. As indicated above, you should use the maximum power input of 115 VA of each power supply to calculate this most accurately.

Using the conversion factor:

  • Heat Dissipation = 115 x 3.41297 = 392.5 BTU/hour.

The metric equivalent to BTU is a Joule where 1 BTU = 1,055 Joules.

This calculates the BTU value per power supply. The maximum BTU per system is therefore calculated, based on total number of power supplies installed in the system. For example, for a IP412, this would be 1 for the base unit and up to 12 for the expansion modules.

  • IP412 Maximum Heat Dissipation = 13 x 392.5 = 5,103 BTU/hr.

Remember to budget for the power requirements of any additional devices that are to be co-located with the IP Office such as server PC's (voicemail, etc).
