Introduction
The Inter-Tel
®
5000 platform provides an enhanced IP solution for small- and medium-sized
business environments. Marketed as Inter-Tel CS-5200, CS-5400, and CS-5600 Communica-
tion Servers, each system supports IP endpoints, Inter-Tel digital endpoints, Inter-Tel IP soft-
phones, standard single line and other endpoints. Depending on optional equipment and
programming options, trunking, and licensing, the Inter-Tel 5000 platform supports 25–250 IP
endpoints, up to 192 digital endpoints, and up to 54 single line analog endpoints.
Technology Highlights
This guide provides detailed descriptions of system capabilities, capacities, and applications
based on the following technology features:
• Software and Hardware Foundation: Inter-Tel 5000 systems provide call processing
(CP) features, Wide Area Network (WAN) Fail Survivability, and a Power Fail Bypass
relay.
• Scalable: In addition to three bays that can be equipped with trunk and endpoint mod-
ules, the Inter-Tel 5000 Base Server provides multiple access ports to the platform. Two
loop start trunks, two single line endpoints, and external voice mail PCs can be con-
nected, as well as Digital Expansion Interface (DEI), Music on Hold (MOH), and pag-
ing equipment.
• Messaging: Basic Voice Mail (BVM) is provided with each system, and additional
voice mail capacity is available by installing either the optional Enterprise
®
Messaging
(EM) system or a Voice Processing Unit (VPU). For details, see “External Voice Pro-
cessing Systems” on page 22. Fax over IP (FoIP) between Inter-Tel 5000 nodes and
Unified Messaging are also available.
• Digital signal processing: Digital signal processor (DSP) technology enables Confer-
encing, Dual Tone Multi-Frequency (DTMF) detection, tone generation, modem opera-
tion, and Automatic Number Identification (ANI), or Caller ID.
• Private networking: Any of the Inter-Tel 5000 systems can operate as a stand-alone
system or function as a node in a network of up to 99 Inter-Tel Axxess or Inter-Tel 5000
nodes. For details about 99 Nodes requirements, see “Network Capability” on page 302
• Oversubscription: For systems that utilize numerous IP endpoints, IP trunks, and IP
networking, v2.x allows oversubscription of IP resources. With oversubscription,
dynamic allocation of IP resources, and Camp On capability, a system can be pro-
grammed with more endpoints than it has IP resources available to support simulta-
neously. For further explanation, see “IP Resources” on page 301. The Resource
Reservation Tool allows reservation of IP resources for essential functions such as
Emergency/911, as well as other customer-specified devices and endpoints.
Stable and reliable performance of the Inter-Tel 5000 platform relies, in part, on maintaining a
clean and controlled environment for the Inter-Tel 5000 equipment. For environmental require-
ments, see Table 42 on page 298.
NOTE
System capacities cited in this guide refer to the maximum number possible before
making resource tradeoffs. The actual number of trunks or endpoints installed on a
system depends on the user’s requirements and the physical constraints and config-
uration of the system.
