Chapter 3: Product Description

System Evolution

System Evolution
An Inter-Tel 5000 platform running on v2.x provides increased IP endpoint capacity for all its
configurations. This increased capacity is achieved by using a less processing-intensive codec
to allocate IP resources than was used in preceding versions. Starting with v2.0, G.711 became
the default vocoder for Inter-Tel 5000 platforms instead of G.729.
Since the release of v2.0, the Inter-Tel 5000 platforms have supported four single line endpoints
with the Single Line Module (SLM-4), part no. 580.2100. Prior to the SLM-4, single line
endpoints were supported on the Inter-Tel 5000 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 of the three systems equipped with one or two Digital
Expansion Interface (DEI) chassis can run up to three eight-port Single Line Modules (SLM-8),
part no. 580.2101, in each DEI. Applicable licensing is required. Having the same form-factor as
the Digital Endpoint Module (DEM-16), the SLM-8 fits in the DEI chassis. For feature
descriptions, installation procedures, and programming instructions, see the appropriate
chapter.
For systems that utilize numerous IP endpoints, IP trunks, and IP networking, v2.0 and later
allows oversubscription of IP resources. With oversubscription, dynamic allocation of IP
resources, and Camp On capability, a system can be programmed with more endpoints than it
has IP resources available to support simultaneously. For oversubscribed systems, the
Resource Reservation Tool allows you to reserve IP resources for essential functions such as
Emergency/911, as well as other customer-specified devices and endpoints.
With v2.1 and later running on the Inter-Tel CS-5600 platform, a separate Processing Server
(PS-1) handles call processing and supports 16-port Basic Voice Mail. The PS-1 controls and
communicates with the Inter-Tel CS-5200/5400/5600 Base Server across the customer's local
area network (LAN).

The Base Server is actually an Inter-Tel CS-5400 that, to avoid confusion
hardware-wise, is called a Base Server when it functions as a component of an
Inter-Tel CS-5600 system.
