Strata CIX General Description

Connectivity
IP telephones connect to either the MIPU, LIPU, LIPS in the Strata CIX system running software
version 5.2 or above. However, the IPT2008-SDL can only be connected to the MIPU,
LIPU/LIPS. These telephones must be connected to MIPU / LIPU / LIPS to use peer-to-peer
Real Time Protocol (RTP) connection.
Note
The Strata CIX also supports the IPT1020-SD. This telephone can be connected to a
BIPU-M card only. It does not support peer-to-peer RTP connection.
• These telephones do not use the System power supply, so there is no power restriction to limit
the number of IP telephones that can connect to an individual Strata system. The IP Telephones
have built-in connectors. The back of the telephone has connector labels. The telephones can be
powered by a local power supply on the PoE (Power over Ethernet).
• The RJ45 LAN jack connects the telephone to the network via the LAN cable supplied with the
telephone. These telephones operate on the network at 10/100Mbps and 1000Mbps(IP5000-
series only) and can be connected to a fast switch hub, router, LAN, WAN, etc.
• The RJ45 PC jack can connect the IPTs to the user’s PC. The IPTs can operate like a switch, as
opposed to a hub, so the telephone can be connected directly to the LAN or Cable/DSL modem,
and then a PC can be connected to the telephone PC jack to connect to the LAN through the
telephone.
• The built-in headset jack enables headsets to be connected to the telephone. No optional
headset interface is required. The same carbon or ECM headset support used on Toshiba digital
telephones can also be used on IP telephones.
Capabilities
The Toshiba IP Telephones also have the following capabilities:
• The IPTs contain two types of codecs (coder/decoder): G.711 and G.729A. The codec
determines the IP telephone voice quality and network bandwidth requirements. The G.711
requires the most bandwidth and provides the best voice quality. The G.729A requires less
bandwidth, but it does not provide the best voice quality. The desired codec is selectable for
each IP telephone in IP station administration using eManager or Network eManager.
• The external ringer interface connector is mounted inside the telephone base. This enables
connection of an BESCB external speaker device to provide a loud ringer for the IP telephone.
• All telephones in the system can be IP telephones up to the system’s maximum station capacity
(see
Table 32 on page 134
).
• Terminal Authentication is an option that allows a particular IP telephone to keep a reserved
directory number on a CIX system. This prevents IP telephones from logging in with another
telephone’s directory number if the other telephone has been disconnected to be taken to
another location. This feature uses the unique Media Access Control (MAC) address that is
permanently coded into each telephone network interface circuit. The unique MAC address of
the telephone is assigned to a particular directory number in system programming.
• IPT firmware can be updated locally or remotely using eManager. This enables service
personnel to update IP equipment with new features and enhancements as they become
available. Updates require a brief interruption of IP telephone operation (a few minutes).
• IP telephones have a discovery retry timer to prevent network congestion when many IP
telephones request services simultaneously. If network congestion is detected, the telephone
will pause and then retry for service.
• IP telephones have loop back and ping capabilities for maintenance and fault finding purposes.
• IP telephones support Dynamic Host Configuration Protocol (DHCP) or static IP addressing.
