Chapter Overview
This chapter discusses the MiVoice Office 250 family of products that provide an enhanced IP
solution for small- and medium-sized business environments. The MiVoice Office 250 is a family of
converged communications platforms that supports Internet Protocol (IP), digital, and analog single
line phones.
System Description Changes
Prior to v4.0, the system was marketed as the CS-5200, CS-5400, and CS-5600 communication
servers. Starting with the v4.0 release, these CS-5200, CS-5400, and CS-5600 product model
designations are no longer used, and the original CS-5x00 hardware platform is now referred to as
the CS Controller platform. The newer hardware platform is referred to as the HX Controller platform.
Also starting with the v4.0 software release, hardware expansion options have been simplified and
are now independent of licensing. For example, a new license is no longer required to add a
Processor Expansion Card (PEC-1) or a Processing Server (PS-1) to the system. Release 6.1
introduced the PS-1 as a virtual appliance. As a result, system capacities that were tied to the 5x00
size designations (e.g., a CS-5200 being limited to 75 IP phones) are no longer enforced. A system
can now be equipped with up to 250 phones (up to 240 digital or up to 250 IP) as long as the phones
are properly licensed.
Instead of using Digital Expansion Interface (DEI) licensing, digital telephones are now licensed the
same way that IP phones are licensed in the system. A new category E license was added in v4.0
for digital telephones. When upgrading existing systems to v4.0 or later, the AMC will convert the
old DEI licensing model to the category E licensing model. Each DEI license is converted to 48
category E licenses. Note that SLAs attached to digital circuits do not require a license.
Due to these changes in licensing, the IP Endpoints Enabled and System IP Endpoint Capacity
values have been eliminated from the Software License Feature folder in DB Programming. Also,
an Extended Node Capacity license is no longer required to go above 63 nodes.
System Evolution
Starting with v2.0, G.711 became the default vocoder for MiVoice Office 250 instead of G.729. This
change provided increased IP phone capacity by using a less processing-intensive codec to allocate
IP resources than was used in preceding versions.
Also since v2.0, the system has supported four single line phones with the Single Line Module
(SLM-4), part number 580.2100. Prior to the SLM-4, single line phones were supported on the
MiVoice Office 250 by digital Single-Line Adapters (SLA), IP SLAs, or the two single line ports built
into the Base Server. The built-in single line ports are wired to connect with two built-in loop start
trunk ports, which provides the system with power fail bypass capability.
In addition, with v2.1 or later, any system equipped with one or two Digital Expansion Interface (DEI)
chassis can run up to three eight-port Single Line Modules (SLM - 8), part number 580.2101, in each
DEI. Having the same form-factor as the Digital Endpoint Module (DEM-16), the SLM-8 fits in the
DEI chassis.
NOTE
Starting with the v4.0 software release, the lack of a PEC-1 and/or a PS-1 (or vPS-1) no
longer reduces the maximum feature capacities available on the system. For a list of
capacities, see “System Capacities” on
