IP Telephone Features
System Availability: Strata CTX100, CTX670
The Toshiba IPT1020-SD IP telephone is
a 20-button speakerphone with a two-line
by 24-character display. It looks and
functions just like a DKT3020-SD digital
telephone; however, it has different built-
in connectors (shown right):
The AC adapter (model BADP120-
1A supplied with the IPT1020-SD)
powers the telephone if PowerDsine’s
Power Over LAN
TM
is not used (see
“Power Over LAN” on page 80 for
details). IPT1020-SDs do not use the
CTX power supply, so there is no
power restriction to limit the number
of IP telephones that can connect to an
individual Strata CTX cabinet.
The RJ45 LAN jack connects the
telephone to the network via the
10Base-T/100Base-TX cable supplied
with the IPT1020-SD. The IPT1020-
SD operates 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 IPT1020-SD to the user’s PC. The IPT1020-SD 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.
The IPT1020-SD also has the following attributes and capabilities:
The IPT1020-SD contains 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 CTX WinAdmin.
The external ringer interface connector is mounted inside the telephone base. This enables
connection of an HESB external speaker device to provide a loud ringer for the IP telephone.
Existing tilt stands (BTSD and BTSA) are compatible with then IPT1020-SD to adjust the
angle of the telephone as desired.
