The IP412 Office base unit is 19" rack mountable and supports as standard:
- Two 10/100 switched Ethernet ports.
- DTE Port.
- X.21/V35 WAN interface.
- Support for 12 Expansion Modules (360 extensions maximum).
- Two relay switch port for door entry systems (Ext O/P socket).
- Audio port for external music on hold source.
- 100 Data channels (Maximum 30 useable for Voicemail Pro).
Note: A data channel is 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.
Optional internal upgrades allow for the support of up to 12 x V.90 modem calls and two 5, 10, 20 or 30 channel Voice Compression Modules (VCM). Fitted with two 30 channel voice compression modules, 60 simultaneous voice over IP sessions can be supported. These can be used for either providing networking between sites over a wide area network or supporting IP Telephones and Soft phones. An IP extension only uses the compression module whilst on a call to a non-IP extension/line. Hence, it is possible to support more extensions than the capacity of the VCM's.
IP412 Office can be expanded by 12 Expansion Modules, however this is restricted to a maximum capacity of 360 Analog or Digital Stations.
The IP412 Office is available pre-configured with a single or dual PRI (E1/T1 Lines ) and a spare slot for an optional Quad Analog Trunk, Quad Basic Rate, PRI or Dual PRI (E1/T1).
