IP Telephones

Connectivity

IP telephones connect to either the MIPU, LIPU, LIPS or GIPH in the Strata CIX system running
software version 3.1 or above. However, the IPT2008-SDL can only be connected to the MIPU,
LIPU/LIPS or GIPH. These telephones must be connected to MIPU / LIPU 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 RJ45 LAN jack connects the telephone to the network via the 10Base-T/100Base-TX cable
supplied with the telephone. These telephones operate on the network at 10/100 Mbps 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 headsets used on Toshiba digital
telephones can 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.
• 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
• 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.
