Mitel 3300 - Network; Lines; Trunks

System

• Unified Messaging - Enables the 6000 Managed Application Server to synchronize voice
mail messages with a 3300 ICP, and to manage those messages with a standard e-mail
client using the IMAP (Standard Unified Messaging) protocol.
The Application Processor Card requires a dedicated hard drive.
Network
Lines
The 3300 ICP supports the following internal voice connections:
• 10/100BaseT Ethernet connections are required for Mitel IP telephones to connect to the
customer's Ethernet LAN. A single 10/100BaseT Ethernet connection is required to connect
to the 3300 ICP Controller.
• On-Premises (ONS) lines (24V per port) are for industry-standard DTMF telephones. The
external loop resistance on an ONS line must be 600 ohms or less, and the loop length
must be 5000 feet (1500 meters) or less on 26-gauge wire. These lines are supported by
the ASU II and the ONS line card in the Peripheral unit or MicroLIGHT. Note: Pulse and
rotary dial telephones are not supported by the ASU II, AMB, or AOB.
• Off-Premises (OPS) lines (48V per port) are for industry-standard telephones where the
external loop resistance exceeds 600 ohms or where lightning surge protection is required.
The maximum resistance on an OPS line must be 1800 ohms or less, and the loop length
must be 19,000 feet (5800 meters) or less on 26-gauge wire. These lines are supported by
the OPS line card and are only available if a Peripheral unit or MicroLIGHT is installed.
• Digital Network Interface (DNI) lines provide an interface for Mitel digital telephones, and
consoles. The maximum loop resistance on a DNI line must be 280 ohms or less, and the
loop length must be 3300 feet (1000 meters) or less on 26-gauge wire. These lines are
supported by the DNI Line card and are only available if a Peripheral unit or MicroLIGHT
is installed.
Trunks
The system can connect to the Public Switched Telephone Network (PSTN) or to private
networks over both digital and analog trunks.
The following digital links are supported:
• DS1 Links - The system supports D4, Q.Sig, MSDN/DPNSS, Primary Rate ISDN (DM-250,
DMS-100, Bellcore National ISDN, 4ESS, NI-2, 5ESS NI2, N13), and XNET over PRI
protocols. The system connects to DS1 links through the Universal NSU or the DS1 For-
matter card in the DSU cabinet or MicroLIGHT. (See Note below.)
• E1 Links - The system supports DASS II, MSDN/DPNSS, Q.Sig, Primary Rate ISDN (Euro
ISDN (CTR4)), and XNET over PRI protocols. The system connects to E1 links through the
Universal NSU or the CEPT Formatter card in the DSU cabinet or MicroLIGHT. (See Note
below.)
