Page 16 System Network Capacities
IP Single-Line Adapters (IP-SLA), Single-Line Adapters (SLA), and single line analog
phones and other endpoints.
• Pocket PC SoftPhone: The Model 8601 is a SIP softphone that runs on selected Pocket
PC 2002 (or later) Personal Digital Assistant (PDA) platforms. The IPRA supports the
Model 8601 Pocket PC SIP-mode softphone, which is described in the following para-
graph, but does not support Inter-Tel legacy IP SoftPhones.
• Multi-protocol phones: A multi-protocol phone is one that operates either in Inter-Tel
Protocol (ITP) mode or in Session Initiation Protocol (SIP) mode. A SIP server is
required for SIP mode operation. Multi-protocol phones include Models 8620/8622,
8662, and 8690. Multi-protocol phones require software licenses.
• Wireless phones: Models 8664, 8665, and 8668 are wireless phones that operate in ITP
mode.
• Single line phones: In addition being able to install single line phones in each of the
two circuits built into the Inter-Tel CS-5200/5400 chassis, one single line phone can be
installed in with each IP-SLA, and two single line phones can be installed with each
SLA.
System Network Capacities
Two or more Inter-Tel Advanced Communications Platforms (Inter-Tel 5000 or Axxess) can be
connected to form a network that provides a seamless interface between the systems. To the
user, the network appears as one integrated system. With few exceptions, the user can perform
all of the functions across the network that can be performed within a single system.
In this guide, all references to a “network” mean two or more connected systems. Each system
in a network is called a “node.”
The maximum capacities for networking appear in Table 2.
* The maximum number of endpoints and trunks that can be installed is limited by the number
of voice channels and/or system memory resources available.
Voice Processing Systems
Inter-Tel CS-5200/5400 Communication Servers support an internal Inter-Tel 5000 voice pro-
cessing system, Basic Voice Mail (BVM), and two external voice processing systems, the
Voice Processing Unit (VPU) and Enterprise Messaging (EM).
Basic Voice Mail
Basic Voice Mail (BVM) is built into Inter-Tel 5000 platform capability to provide voice mail
and messaging services. BVM does not support Fax-On-Demand or Unified Messaging.
BVM messages are stored on a CompactFlash (CF) memory card formatted by Inter-Tel. The
card also stores system applications and the user database.
