IP Office IP412 Control Unit
With a greater internal data transfer capability than the IP406 V2, the IP412 is more suitable for meeting the needs of the small contact center or businesses with a CRM focus. The IP412 differs from the IP4060 V2 by providing a greater trunk expansion capability of up to four PRI trunks. The IP412 is a stackable unit with an optional 19" rack mounting kit. The IP412 includes:
Through support of up to twelve external Expansion Modules, IP412 can be enhanced to support a mixture of analog, digital or IP phones, to maximum of 360 phones in any combination.
If additional analog trunks are required, these can be aggregated in groups of 16 on each analog expansion module.
A Data Channel is used for Remote Access (RAS), Internet Access, and Voicemail sessions. A data channel is an internal signaling resource used whenever a call is made from the IP network to an exchange line (Central Office). For example, four people surfing the Internet will use a single data channel since they all share the same line to the ISP. Two people remotely accessing the Office LAN from home will use two data channels since they have dialed in on separate lines. IP extensions do not use data channels. Data channels are used for voicemail connections with a maximum of 30 available for VoiceMail Pro on a IP412.
Modems and Voice Compression modules
You can add additional hardware to the IP412 system to add one modem card (12 V.90 modems) and 2 Voice Compression Modules (VCM). Each VCM supports from 4 to 30 simultaneous Voice over IP sessions and is used for either providing networking between sites over a Wide Area Network or supporting IP Telephones and Soft phones.
IP400 Trunk Interface Cards
IP400 trunk interface cards fit into the card slots on the Small Office Edition, IP406 V2 and IP412 control units and in any slot of the IP500 when combined with the IP500 Legacy Card Carrier. They provide analog, ISDN or CAS trunk connectivity. Not all interfaces are available in all territories. The following table shows how many of each card type are supported by each of control unit.
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.
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.
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:
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.
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).
