Page 390

Issue 22.a.- (21 March 2011)

Expansion Modules

Through support of up to six external Expansion Modules, IP406 can be enhanced to support a mixture of

analog, digital or IP phones, to maximum of 190 phones in any combination.

If additional analog trunks are required, these can be aggregated in groups of 16 on each analog expansion

module

Data Channels

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 20 available for VoiceMail Pro on an IP406 V2.

Modems and Voice Compression modules

You can add additional hardware to the IP406 system to add one modem card (2 or 12 V.90 modems) and 1

Voice Compression Module (VCM). The 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 WAN3 10/100

All IP400 control units except IP500 and IP500 V2

The IP400 WAN3 10/100 module provides three WAN connections (X21, V35 or V24 via a 37way D Type socket

and using an appropriate connector cable). Data rates of up to 2 Mbps are supported on each interface, the

carrier providing the line dictates the actual operating speed i.e. in some territories the maximum speed may be

limited to 1.544 Mbps. These WAN interfaces are identical to the single WAN connection provided as standard

on the IP406 and IP412 platforms.

The IP400 WAN3 10/100 connects to the control unit through the Local Area Network via a 10/100Mbps

connection and does not use an expansion port on the control unit. IP500 does not support the WAN3 10/100.

All other platforms support up to two WAN3 10/100 modules.
